In which application does glycerine NOT serve as a humectant in the food industry?
-
A.
To prevent the oxidation of food colour
-
B.
To control ice crystal formation in frozen desserts
-
C.
To retain moisture in processed meats
-
D.
To maintain consistency and prevent drying in dairy products
Correct Answer:
A. To prevent the oxidation of food colour
Explanation:
Glycerine is widely utilized in the food industry as a humectant due to its hygroscopic nature, which allows it to attract and retain water. This function is essential for maintaining the moisture content in processed meats, preventing dairy products from drying out, and controlling the development of ice crystals in frozen desserts to ensure a smooth texture. However, preventing the oxidation of food color is not a function of glycerine as a humectant; instead, it typically serves as a solvent or carrier for such additives. Therefore, the application where it does not function as a humectant is preventing the oxidation of food color.
