Description

L-cystine is an organic compound with the molecular formula C6H12N2O4S2 and a molecular weight of 240.3. L-Cystine is a white hexagonal plate-like crystal or white crystalline powder, soluble in dilute acids and alkaline solutions, extremely insoluble in water, and insoluble in ethanol. L-Cystine exists in small amounts in proteins and is mostly found in keratin in hair, fingers, claws, etc.

Advantages:

L-cystine promotes protein synthesis, maintains cell structure and antioxidant capacity (through the synthesis of glutathione).
L-cystine supports the health of hair, skin and nails (as a component of keratin).
L-cystine has an auxiliary detoxification function (participating in liver metabolism).

Application

Bread and baked goods
Fermentation accelerator: L-cystine can be used as a fermentation accelerator for bread and other baked goods, which helps improve the fermentation performance of the dough and makes the bread softer and more delicious.
Preservative: Adding L-cysteine to baked goods can also have a preservative effect and extend the shelf life of the food.
Dairy products
Dairy additive: L-cystine is used as an additive in dairy products, which can enhance the taste and nutritional value of dairy products.
Juice beverage
Antioxidant: L-cystine can prevent the oxidation of vitamin C in juice, prevent the Browning of juice, and maintain the bright color and nutritional value of juice.
Nutritional fortifier
Supplement amino acids: L-cystine is one of the essential amino acids for the human body and it has multiple physiological functions within the body. Adding L-cystine to food can serve as a nutritional fortifier to enhance the nutritional value of the food.
Improve the taste and texture of food
Enhancing taste: When L-cystine is heated with sugars in food, it can produce various special aromas, which helps to enhance the taste of the food.
Enhancing texture: Adding L-cystine to noodle products can improve the taste of raw noodles, dry noodles and fried noodles, making them more chewy. Meanwhile, it can also enhance the adhesion and extensibility of flour products, improve moisture retention, reduce cracking due to freezing, and further improve the texture of food.
Other applications
Food flavoring agent: L-cystine has a unique umami flavor and can be used as a food flavoring agent to enhance the umami and flavor of food.
Meat products: In meat products and paste-like aquatic products, L-cystine can be used as a surface gelling agent to strengthen the texture and maintain a fresh taste.
