FAQ

Q1: What is the greatest advantage of lactone tofu made with GDL compared to tofu made with traditional gypsum or salt brine?

 

A1:The greatest advantage of Renze GDL lies in its extremely tender and smooth texture and stable quality. Lactone tofu has a texture as smooth as pudding, and it has good water retention. Its yield and shelf life are both higher, making it suitable for the market.

 

Q2: Can GDL be used in other foods besides making tofu? How safe is it?

 

A2: Of course. Renze GDL is a safe and multi-functional food additive.

Versatility: Besides serving as a coagulant for tofu, it is also a mild acidulant used in beverages and candies. It is a key component of leavening agents and is used in steamed buns and cakes. It is used as a gel promoter in jelly and pudding to make the texture more stable. It can also play a certain anti-corrosion role.

Safety: GDL is a natural oxidation product of glucose and is widely present in natural foods such as honey and fruit juice.

 

Q3: What are the practical operational advantages of using GDL for food producers?

 

A3: The process control of Renze GDL is simpler and the yield rate is higher. Easy to use, just mix well. The reaction is controllable and the quality is uniform.
