Cysteine is one of the components of glutathione, which can accelerate the aging of free radicals.

Trehalose is a typical stress metabolite that can form a unique protective film on the surface of cells under harsh environmental conditions such as high temperature, high altitude, high osmotic pressure, and dehydration, effectively protecting the structure of biomolecules from damage and maintaining the life processes and biological characteristics of living organisms

The application range of sucralose is becoming increasingly wide, mainly due to its obvious advantages Sucrose has high safety and no side effects, with an AD value of 15mg/kg Sucralose has a high degree of sweetness and is currently one of the most successful sweeteners in research and development projects.

The principle of vitamin C (and its salts such as sodium ascorbate) in color preservation of meat products is one of its core applications, involving complex redox reactions and nitrite chemistry. Its mechanism of action can be clearly explained through the following four key steps:

Vitamin C (mainly L-ascorbic acid and its salts) plays multiple roles in food through its unique chemical properties, with the core being that it is a potent reducing agent (electron donor) and possesses organic acid properties. Its mechanism of action is closely related to its application scenarios. The following is a detailed analysis:

The following is a comparison of the core differences between L-cysteine hydrochloride and L-cysteine, covering chemical properties, stability, application scenarios, and selection criteria:
