It is the sodium salt of benzoic acid and exists in this form when dissolved in water. It can be produced by reacting sodium hydroxide with  benzoic acid . Production: Sodium benzoate is produced by the neutralization of benzoic acid,which is itself produced commercially by partial oxidation of toluene with oxygen. Natural occurrence: Sodium benzoate occurs naturally, along with benzoic acid and its esters, in many foods.Fruits and vegetables can be rich sources, particularly berries such as cranberry and bilberry, other sources include seafood such as prawns, and dairy products like milk, cheese and yogurt.

Application Of Plant Growth Regulator On Wheat 1. Promoting wheat germination Triacontanol. In the treatment of wheat and wheat seeds with 30 alkyl alcohol, the activity of enzyme in seed can be improved and the metabolism of enzyme is promoted, which is beneficial for material transportation and provides energy for growth and development, raising germination rate and making the seedling early and orderly. According to the experiment of agricultural technology promotion station in xintai city, shandong province, The seeds were planted for 4-12 hours after sown with 0.2-0.5 mg/litre of 30anol, which bring an increase of 4.3%-7.1% per mu. Before the wheat seeding, it had better soak in 0.2-0.5 mg/litre of 30 alkyl alcohol for 4-12 hours. Generally speaking, every 15kg of wheat is sprayed with 30 alkanol, which can be seeded after 2 to 4 hours. Precautions: strictly use the concentration to avoid side effects. Plant Growth Regulator can be mixed with insecticide, fungicide Cytokini...

Vitamin C, also known as  L-ascorbic acid , is an essential nutrient for higher primates and other minorities. Ascorbic acid can be produced by metabolism in most organisms, but human beings are the most notable exception. The most widely known is the lack of vitamin C which can cause scurvy. Both humans and animals can take vitamin C,The pharmacophore of vitamin C is ascorbate. In the body, vitamin C is an antioxidant because it protects the body from the oxidant. Vitamin C is also a coenzyme. Most animals can synthesize vitamin C by themselves, but humans, marmosets, guinea pigs, etc. must be taken from food; vitamin C plays an important role in the formation of collagen. Collagen is an important substance for the development and repair of human tissue cells, gums, blood vessels, bones and teeth and help the body's absorption of iron. Ⅰ：Vitamin C function: Ⅰ: Main physiological function 1. Promote the biosynthesis of collagen. Conducive to the faster healing of the tissue w...

Food additives are substances added to food to preserve flavor or enhance its taste, appearance, or other qualities. Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as with wines. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin. Food additives can be divided into several groups, although there is some overlap because some additives exert more than one effect. For example, salt is both a preservative as well as a flavor. Acidity regulators ：Acidity regulators are used for controlling the pH of foods for stability or to affect activity of enzymes. Food coloring ：Colorings are added to food to replace colors lost during preparation or to make food look more attractive. Fortifying agents：Vitamins, minerals, and dietary supplements to increase the nutritio...
