Sulfite

Sulfites are compounds that contain the sulfite ion SO32-.Sulfite ion is the conjugate base of bisulfite.It occur naturally in all wines.Sulfites are commonly introduced to arrest fermentation at a desired time, and may also be added to wine as preservatives to prevent spoilage and oxidation at several stages of the winemaking.It is also used as preservatives in dried fruits, preserved radish, and dried potato products.Sulfite content in the blood and urine of babies can be caused by molybdenum cofactor deficiency disease which leads to neurological damage and early death.

Sulfur Dioxide

Sulfur dioxide is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide unless the sulfur compounds are removed before burning the fuel. Sulfur dioxide is an intermediate in the production of sulfuric acid. It used as a preservative for dried apricots and other dried fruits owing to its antimicrobial properties. As a preservative, it maintains the appearance of the fruit and prevents rotting. Sulfur dioxide is also a good reductant. In the presence of water, sulfur dioxide is able to decolorize substances. Specifically it is a useful reducing bleach for papers and delicate materials such as clothes. Sulfur dioxide is a versatile inert solvent that has been widely used for dissolving highly oxidizing salts. It is also used occasionally as a source of the sulfonyl group in organic synthesis.

Tertiary Butylhydroquinone

tert-Butylhydroquinone is an aromatic organic compound which is a type of phenol. It is a derivative of hydroquinone, substituted with tert-butyl group. It is a highly effective antioxidant. In foods, it is used as a preservative for unsaturated vegetable oils and many edible animal fats. It does not cause discoloration even in the presence of iron, and does not change flavor or odor of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole. It is used industrially as a stabilizer to inhibit autopolymerization of organic peroxides. In perfumery, it is used as a fixative to lower the evaporation rate and improve stability. It is also added to varnishes, lacquers, resins, and oil field additives.

Trehalose FOOD GRADE 98%

Trehalose Food Additives

USES of trehalose:

l low sweetness food: all kinds of snacks, cakes, bean paste, jam, seasoning seasonings processed food in general.(instead of 10 to 100% white sugar)

l improve taste: canned food, fermented food, flavoring, health foods and material, improve alkali flavor, taste, spicy taste, inhibition of bitterness and astringency, etc.(it can be added between 0.5-7%, depending on the product.)

l protect aging protein: applied to the noodles, bread, rice, butter, barbecue seasoning sauce, Fried starchy foods such as meat pie in can receive good effect, the effect was more marked in low humidity or frozen.Frozen conditioning food (fish balls, fish paste products, etc., can improve tissue, enhance elasticity and patience, lactic acid bacteria beverages (increase the number of living bacteria and inhibit the fermentation flavor)

l resist moisture absorption: dried meat, pork floss, chocolate, chewing gum, donuts, particles, powder and seasoning, seaweed and processed foods, all kinds of powder coating, mix (of powder with 5%, and the rest right amount add)

l results sex: jelly, hard candy, lollipop, candied fruit, sugar and other (instead of 40-80% of white granulated sugar)

l keep food color, inhibiting Browning: keep bright red, to reduce the sweetness of strawberry jam, strawberry characteristic flavor and odor.

Fresh fruits, vegetables, trehalose can replace the role of water in plant and animal tissues or cells, namely in tissue and cell water loss, to play a number of benefits protection organization, the structure of a cell is not affected by dry and freeze damage.Therefore, the preservation of vegetables, meat and fruit is very effective.

Trisodium Citrate

Trisodium citrate is the sodium salt of citric acid. It is chiefly used as a food additive, usually for flavor or as a preservative. As a conjugate base of a weak acid, it can perform as a buffering agent or acidity regulator, resisting changes in pH.Trisodium citrate is used to control acidity in some substances, such as gelatin desserts. It can be found in the mini milk containers used with coffee machines. It is used as an anticoagulant in blood transfusions. It is also used to relieve discomfort in urinary tract infections, such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative.

ascorbic acid FOOD GRADE 99%

Ascorbic Acid is a naturally occurring organic compound with antioxidant properties. It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. Because it is derived from glucose, many animals are able to produce it, but humans require it as part of their nutrition. Other vertebrates which lack the ability to produce ascorbic acid include other primates, guinea pigs, teleost fishes, bats, and some birds, all of which require it as a dietary micronutrient (that is, in vitamin form).
