Tartaric acid is an organic acid found in plants such as grapes, tamarind and bananas. It is a dibasic acid, which means that the molecule that can be ionized in water has a hydrogen atom on each side. Tartrates are also known as sodium tartrate. This acid was originally taken from potassium tartrate, which was isolated by "ibn Hayyan" at the beginning of the 9th century. Later, in 1769, the Swiss chemist Carl Wilhelm Scheele invented the modern method of obtaining tartaric acid.

The acid can be produced naturally, but it can also be produced synthetically. DL Tartaric acid and endotartaric acid are the two forms of tartaric acid that can be synthesized. The pure form of tartaric acid was first created by Louis Pasteur in 1847.

One of the interesting properties of tartaric acid is that it is chiral. This means that its internal structure does not have a plane of symmetry and has a mirror image that cannot be superimposed. A chiral mirror image is also known as an enantiomer and can be compared to a human hand.

The most common use of tartaric acid is as a food additive. It is often added to specific types of candy to add a sour flavor. Typical uses for cream of tartaric acid are to stabilize egg whites and as an active ingredient in baking powder. The acid can also be found in wine.

Tartaric acid is also used as an emetic to induce vomiting and has laxative properties. In addition, it has antioxidant properties. This means that tartaric acid is able to limit or prevent the oxidation of molecules in the body, preventing the formation of free radicals.

High levels of tartaric acid are dangerous because it can act as a muscle toxin. It inhibits the production of malic acid and an overdose can lead to paralysis or death. About 7.5 grams or so of tartaric acid per kilogram of body weight can be fatal. This means that a 70-kilogram person would have to ingest at least 500 grams to die of poisoning.

Carrageenan is a collective name for a group of linearly sulfated polysaccharides derived from marine edible red algae, including Hordeum vulgare, Kirinia, Saccharomyces cerevisiae and Sarcophyllum. These polysaccharides are widely used in the food industry due to their ability to bind stably to proteins in food, e.g. as coagulants, thickeners or stabilizers for dairy and meat products. 

The chemical structure of  Carrageenan is a linear polysaccharide compound consisting of D-galactose and 3,6-anhydro-D-galactose residues. And according to the different positions of the semi-ester sulfate groups attached to the galactose, carrageenan can be divided into seven types: k-carrageenan, L-carrageenan, r-carrageenan, λ-carrageenan, ξ-carrageenan, φ-carrageenan, θ-carrageenan. And the current production and use of k-type, L-type and A-type carrageenan or their mixtures, especially to k-type is common.

Carrageenan is a safe food additive that has been confirmed through long and rigorous scientific research.

Carrageenan is currently certified by food regulatory agencies in China, the United States, Europe, Japan and Brazil, and is considered safe by the World Health Organization (WHO), the Food and Agriculture Organization, and the Joint WHO Expert Committee on Food Additives (JECFA). Of course, there are still some studies questioning the safety of carrageenan, mainly focusing on whether overconsumption can affect intestinal health, but these views are currently controversial.

According to GB 2760-2014 “National Food Safety Standards for Food Additives” issued by the Health and Welfare Commission, carrageenan is only required to be “used in moderation according to the needs of production” in diluted cream, butter and butter concentrate, raw and wet noodle products, spices, fruit and vegetable juices; and the maximum additives in raw and dry noodle products, other sugars and syrups, and infant formulas, respectively, are not allowed to be added to food. In raw and dried noodle products, other sugar and syrup, infant formula, the maximum additive amount is 8.0g/KG, 5.0g/KG, 0.3g/L. This means that, carrageenan in most food categories, there is no “excessive additive”, which also proves that there is no evidence to prove that carrageenan additive amount has a food safety risk.

Degradable carrageenan has been found to cause intestinal inflammation and alter the microbiota, and has been found to be a trigger for inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Food carrageenan and degradative carrageenan are completely different products, sparking controversy over the safety of food additives. The safety of food-grade carrageenan has been confirmed through various studies.

   Fumaric Acid, also known as transbutenedioic acid, fenugreek acid, corydalic acid, or lichenic acid, is a colorless, flammable crystal of a carboxylic acid derived from butene. Fumaric acid tastes like fruit and can be found in the genera fucus, boletus, lichen and Icelandic seaweed.

   Fumaric acid is white granules or crystalline powder, odorless, with specific sour taste, acidity is strong, about 1.5 times as Citric Acid, melting point 286-287 ° C, sublimation above 200 ° C, 290 ° C decomposition, 230 ° C and above the first transformed into adipic acid, and then the loss of water to generate adipic anhydride. Boiled with water can be obtained DL-Malic Acid. Relative density 1.635 (20 ℃), soluble in ethanol and acetone, slightly soluble in water and ether, insoluble in benzene and carbon tetrachloride, solubility in 100g of water: 25 ℃ 0.63g, 40 ℃ 1.07g, 60 ℃ 2.4g, 100 ℃ 9.8g. fumaric acid is very small hygroscopicity, and with sodium bicarbonate neutralization of the smallest amount required. 3% of the aqueous solution of the pH value of 2.0-2.5. 2.5.

   Fumaric acid has a fruity sour flavor, strong acidity, about 1.5 times that of citric acid, so a low concentration of fumaric acid solution can replace citric acid. But because it is slightly soluble in water, generally not used alone, often fish citric acid, tartaric acid compound use, can show the fruit sour flavor.

   Fumaric acid has strong buffering properties to maintain the pH value of the aqueous solution to maintain at 3.0 or so (the pH value of the aqueous solution of 2.25-2.7), which is suitable for the role of preservatives at pH 3.0 or so has a particularly important significance, so it is often used as a combination of preservatives such as one of the main ingredients. In addition, it has a weak antioxidants ability and a stabilizing effect on water-in-oil emulsifiers.

  Theanine is an amino acids discovered by Japanese researchers in 1950 from Yuluo green tea, which is capable of giving off the flavor component of green tea. Represented by chewing gums and candies, theanine has been used in many food and beverage products, including soft drinks and supplements. In recent years, theanine has gradually gained attention for its anti-stress and sleep quality-enhancing effects, and several studies and experiments have been conducted on the ingredient.

  Previous studies have shown that L-theanine can act on the human brain and exert the effect of inhibiting the excitatory effect of tea caffeine. It is well known that the caffeine contained in tea and coffee has the effect of causing nerve excitation and waking up the brain. The L-theanine in tea is believed to release the excitatory effect of caffeine, and it has been proven that the beta wave (i.e., the brain wave that occurs in the state of excitation) that occurs when drinking caffeine is suppressed by L-theanine.

  In humans, the parasympathetic nerves are stimulated when drinking water, which in turn produces a relaxing effect. However, in the case of drinking water, the relaxation effect comes and goes quickly, and the relaxation effect lasts for nearly an hour when drinking theanine-containing water. Regarding the testing of the relaxation effect, here are the results of a study conducted by the Sun Chemical Company's General Research Institute and Aichi Shukutoku University. In this study, eight volunteers were randomly divided into a water drinking group containing 50mg of theanine and a water drinking group containing 200mg of theanine. The results of the study showed that in the theanine 200mg drinking group, alpha waves appeared in the back of the head and the top of the head regions of the subjects, and in the theanine 50mg drinking group, the power value of the alpha band domain in the high anxiety domain cluster increased. From this study, it can be concluded that theanine has a relaxing effect.

  In order to explore the anti-stress effects of theanine, the Department of Pharmaceutical Sciences of Shizuoka Prefectural University issued a research report. When mice were fed drinking water containing theanine under face-to-face rearing conditions, no acceleration of aging was observed. Therefore, it can be seen that theanine can relieve stress and thus inhibit the acceleration of aging by ingesting theanine.

  Theanine is also effective for difficulty in falling asleep and waking up in the middle of the night. Sun Chemical and the Japan National Psychiatric Nervous Center Mental Health Research Institute jointly released the results of a study on the effect of theanine in improving sleep. Although the difference was not particularly significant, the trend of showing a better fall-asleep elapsed assessment in the L-theanine condition, although the effect was not very strong, implies that L-theanine is likely to have a sleep-promoting effect. In terms of sleep efficiency, compared to 93.8% in the placebo group, the L-theanine condition showed a significant improvement of 96.6%. This result suggests that L-theanine not only prolongs sleep duration, but also shows potential to enhance sleep quality.

  The combination of L-theanine and caffeine improves memory function and memory accuracy, and in the case of memory topics reduces distraction-induced inattention, among other things.

  There have been no reports of health damage or side effects of theanine in Japan. In addition, the safety of the theanine has been confirmed during a short period of oral intake. In one study, subjects were given 200 mg of L-theanine once a week for 3 months, and no side effects were observed. However, the Japanese industry believes that reliable information on human safety is currently insufficient and will need to be discussed in detail in the future.

  In China, tea theanine was approved as a new food ingredient in 2014, with an intake of ≤0.4 g/day, excluding foods for infants and young children. It should be noted that there is also insufficient reliable information on safety during pregnancy and lactation. Therefore, avoid use during pregnancy and lactation.

  With regard to drug-drug interactions, in the case of use with antihypertensives, it has been reported that the effects of the drug can be increased. In addition, in the case of concomitant use with stimulants such as caffeine, there is a possibility of weakening the effect of the latter.

Edible gelatin and industrial gelatin are gelatin, basically no difference in appearance, the average consumer can not identify, and the difference lies in the raw materials and different uses. The reason why there will be gelatin in yogurt, jelly and other foods is because gelatin has the physical and chemical properties of strong water absorption and high viscosity, coupled with a fat-free, high protein, cholesterol-free, so gelatin becomes a natural nutritious food thickening agent for yogurt, jelly, Xiao Long Bao and other foods to add a certain texture to be used, but also has a certain role in preserving freshness.

 

To add gelatin to food is known as food gelatin, food gelatin is the use of fresh animal skin by strict safety production control boiling extracted collagen protein, non-toxic and harmless, as long as the requirements of the country in accordance with the packaging labeling, it is not illegal, the public do not need to worry about safety issues, from a nutritional point of view, the addition of food gelatin will not affect the original nutritional value of food.

 

The main character of the recent public unpleasantness is another use of gelatin - industrial gelatin. Industrial gelatine is widely used in a variety of products in the sheet metal, furniture, matches, packaging, paper and other industries, and in which it mainly plays a role in thickening, stabilizing, cohesion and so on. Because it is not used for food, the boiling process is relatively simple, in which preservatives are also added, and its use for food is strictly prohibited.

 

Now the common practice is to collect leather trimmings, through a series of processes, from the leather will be hydrolyzed proteins out, made of gelatin, so can effectively use the waste leather, reduce costs. But the problem is that the waste leather contains a lot of metal chromium, and in the process of dehydrolyzed proteins chromium can not come off clean, so the industrial gelatin with toxicity, if only used for industrial production, will not cause damage to human health.

 

Foods with gelatin are not vegan

Gelatin as a food thickener, used in meat jelly, canned food, candy, sausage, fans, instant noodles, ice cream and other food industries, and food to add a thickener in one of the purposes is to increase the strong taste, such as vermicelli, instant noodles, etc.; Secondly, in order to prevent impact in the process of transportation leads to the collapse of the product shape, such as yogurt. There are many netizens mistakenly believe that fans, vermicelli, yogurt, etc. belong to the vegetarian diet, which is a kind of misinterpretation.

 

This is a misinterpretation because gelatin is added during the production of vermicelli, and gelatin is a product boiled from the skin, bones, tendons and other parts of the animal, so if there is a product that contains gelatin, it can't possibly be vegan, and therefore some vegans shouldn't choose to add gelatin to their products.

 

Nowadays there are some all-vegan gelatin substitutes such as guar gum, carrageenan, etc. There are also many vegan substances that have the same ingredients as gelatin, such as cellulose, agar, guar gum, xanthan gum, carob fruit, fruit jelly, etc., so if you read the ingredients list and see that there is gelatin, then you can know that it's not vegan, but if there are any of the vegan substances mentioned above in the ingredients list, even if you're a vegan, you can eat it now.

Soy protein, known as soy protein, is the protein contained in soy products, which is about 38% or more, four to five times more than cereals. Soy protein is a plant-based protein.

 

Soy protein is a kind of plant protein, its amino acid composition is similar to milk protein, in addition to methionine is slightly lower, the rest of the essential amino acid content are richer, is a plant-based complete protein. In terms of nutritional value, can be equal to animal protein, in the genetic structure is also the closest to the human body amino acids, so it is the most nutritious plant protein. Soy protein has the incomparable advantages of animal protein, soy protein, although methionine is very little, but does not contain cholesterol, its unique physiological active substances --- isoflavones have the effect of lowering cholesterol. Soybean is one of the main crops in China, because it has both edible oil resources and edible protein resources, has a high nutritional value, soy protein is the most abundant protein in nature, the amino acid composition and the composition of essential amino acids similar to the human body, but also rich in calcium, phosphorus, iron, oligosaccharides and a variety of vitamins, is known as the “gold of growth. Gold”. Industrialized soy protein products include soy protein powder (SF), soy protein concentrate (SPC), soy protein isolate (SPI) and soy tissue protein (TSP).

 

FAO/WHO (1985) human test results show that the essential amino acid composition of soy protein is more suitable for human needs, for people over two years of age, the physiological efficiency of soy protein is 100. soy is rich in protein, and its protein content is almost twice as much as that of meat, eggs and fish. Moreover, the protein contained in soybeans has sufficient content of “essential amino acids” and complete components, which belongs to “high-quality protein”. The human body's demand for protein varies according to age, gender, weight, job type and so on. In order to guide people's diet, countries around the world combined with the actual situation of their own country respectively formulated the “recommended daily supply of dietary nutrients” In 1999, the U.S. Food and Drug Administration issued a statement: 25 grams of soy protein intake per day, there is a reduction in the risk of cardio-cerebral vascular disease.

 

There are two types of soy protein products: powdered soy protein products and textured soy protein products.

Powdered soy protein products are soybean as raw material by degreasing, removal or partial removal of carbohydrates and soy protein-rich products, depending on the protein content is different, divided into three kinds:

(1) soy protein powder, protein content of 50-65% (dry basis);

(2) soy protein concentrate, protein content of 65-90% (dry basis), with soy protein concentrate as raw material by physical modification and obtain the With emulsification, gel and other functions of the product is called functional soybean protein concentrate.

(3) soybean isolate protein, protein content of 90% (dry basis) or more. Soybeans are rich in protein, its content is wheat, rice and other cereal crops more than twice, usually between 40% and 50%.

 

The storage protein is the main body of soybean protein, accounting for more than 70% of the total protein, including 7S globulin (soybean with globulin) and 11S globulin (soybean globulin), and other storage proteins, such as 2S, 9S, 15S and so on, the content of a smaller amount. In addition to storage proteins, soy protein also contains some biologically active proteins, such as β-amylase, cytochrome c, phytohemagglutinin, lipoxygenase, urease, Kunitz trypsin inhibitor and Bowman-Birk trypsin inhibitor. Often, these inhibitors are removed during processing or inactivated by special means to improve the digestibility of soy products. In addition, isoflavones, saponins and lecithin are usually present in different types of commercially available soy protein products.

 

In terms of amino acid content, soy protein is the only plant protein reported to contain the nine essential amino acids required by the human body and to meet the human body's needs, and it is recognized as a full-valent protein, with the protein evaluation index PDCAAS (Protein Digestibility Corrected Amino Acid Score) reaching the maximum value of the evaluation, as do casein and egg white.1 From the point of view of amino acid requirement, both for 2% and 2% of the total amino acid requirement, soy protein has the highest amino acid content in the world. In terms of amino acid requirements, the essential amino acid content of soy protein meets the daily requirement of the human body for both preschool children aged 2 to 5 years and adults. However, for infants, the addition of threonine, methionine, lysine and tryptophan in appropriate amounts can increase the potency ratio and net protein ratio of soy protein.

 

The modern population needs foods that are appetizing, free of adverse side effects, and rich in nutrients. Among the existing food groups, there is no other crop with these conditions and abundant sources of raw materials than soybeans. Drinks made from soy protein are known as “green milk” by nutritionists. Soy protein is effective in reducing high cholesterol in people with high cholesterol. Soy protein drinks in the arginine content than milk, its arginine and lysine ratio is also more reasonable; the lipids, linoleic acid is extremely rich and does not contain cholesterol, can prevent cardiovascular disease in adulthood. Rich lecithin, can remove excess sterols in the blood, “vascular scavenger” reputation.

 

Soy protein drinks are easier to digest and absorb than milk. Milk into the stomach is easy to form large and hard lumps, while soy milk into the stomach is formed into small slices, and fluffy not hard, can make it easier to digest and absorb. These soy proteins are essential nutrients for everyone, but most of them are insufficient through daily dietary intake and must be supplemented by consuming protein powders, especially for certain special groups such as children, pregnant women, lactating mothers and the elderly.

Allulose is a well-studied rare sugar that has been granted GRAS certification by the US FDA, meaning it is generally recognized as safe as a food ingredient under the conditions of intended use in food and beverages. However, allulose has not been listed in China for the time being. Allulose is an isomer of fructose, a monosaccharide with very low content in nature. It is found in natural foods such as fruits, raisins, figs and kiwi. White powder, easily soluble in water.

 Allulose Features

1.Low calorie. Calories are much lower than sucrose, about one-tenth of sucrose, and a small amount of calorie is approximately 0

2.The taste is close to that of sucrose. The sweetness of allulose is 70% of that of sucrose, which is very similar to high-purity sucrose. It stimulates the taste buds slightly faster than sucrose. There is no bad taste during consumption, and changes in temperature will not affect its sweetness. High-sweet stevia will feel greasy, and allulose is better at this point.

3.Maillard reaction. Allulose can undergo the Maillard reaction and can replace sucrose in baking.

4.High security. Allulose has passed the GRAS safety certification of the US FDA, and is considered by European and American scholars to be the best substitute for erythritol. Humans generally have a certain tolerance to the intake of sugar alcohols. If the tolerance is exceeded, symptoms such as diarrhea may occur, but allulose will not occur, and it is very safe.

5.Control blood sugar and suppress blood sugar response. Allulose has no effect on blood sugar and suppresses the glycemic response of other carbohydrates when tested with carbohydrates

6. Anti-obesity. Studies have shown that allulose has the potential to pre-obesity in animal models. It suppresses the expression of genes related to fatty acid synthesis and increases the expression of genes related to lipolysis.

Natural Vitamin E has very many benefits for the human body, and it plays a very important role in both health and beauty.

Slows down skin aging and lightens blemishes

Numerous studies have concluded that Vitamin E slows down aging, it is a highly effective antioxidant that blocks free radical reactions. In the body can protect cells from free radical damage, but also can promote protein renewal synthesis, promote the synthesis of certain enzymes and proteins, reduce the activity of catabolic enzymes, promote the normal metabolism of the human body, enhance the body's endurance, reduce the formation of lipofuscin, and improve the elasticity of the skin.

Eliminate free radicals, protect blood vessels

Many factors in life, such as staying up late, smoking, excessive stress, radiation, some chemical drugs will accelerate the generation of free radicals in the body. Free radicals will also attack the cells on the cardiovascular vessels. Natural vitamin E can protect the cells from free radical damage and play a role in protecting blood vessels. Hypertensive patients take natural vitamin E to protect cardiovascular cells, reduce cellular oxygen demand, effectively improve cardiovascular function and slow down the aging of blood vessels. Observational studies have shown that supplementation with natural vitamin E will reduce the incidence of cardiovascular disease events to a certain extent.

Effective against mouth ulcers

Natural vitamin E has antioxidant activity, can prevent the peroxidation of unsaturated fatty acids, reduce the generation of lipid peroxide, and has the effect of stabilizing the protective film. Natural vitamin E can promote local blood circulation, relieve pain, accelerate the healing of ulcers and promote tissue and mucosa repair. Experiments suggest that natural vitamin E can accelerate the healing of ulcers, no side effects through clinical observation, safe and reliable, can effectively shorten the healing time of oral ulcers.

Enhance physiological function, assist in pregnancy preparation

Daily supplementation of natural vitamin E can enhance the physiological functions of the ovaries, promote follicular development, stimulate the function of the anterior pituitary gland to increase gonadotropins; at the same time, it can also improve the development of the corpus luteum, slow down the atrophy and degeneration of the corpus luteum, and increase the level of progesterone. The effects of natural vitamin E go far beyond these points, and should be supplemented appropriately on a daily basis.
