QUALIFIED PRODUCTS |
Preservatives: interfere with microbial enzyme activity, inhibit the growth of bacteria and mold, used in preserves and preserved fruits to prevent deterioration and extend shelf life.
Antioxidants: Preferentially react with oxygen to avoid food oxidation. Add to fried foods and nuts, prevent oil oxidation, protect vitamins, maintain flavor, nutrition and color.
Bleach: When refining sugar, it destroys the pigment structure by reducing effect, makes white sugar, glucose, etc., whiter, and improves the appearance competitiveness of the product.
Processing AIDS: wine brewing to regulate the fermentation environment, inhibit harmful bacteria, help yeast fermentation; Starch processing can improve starch properties, facilitate molding, increase yield and quality.
