The mechanism of action of lactase

The mechanism of action of lactase is mainly to decompose lactose through hydrolysis reaction. Lactose is a disaccharide formed by a molecule of glucose and a molecule of galactose connected by a glyc

What precautions should be taken when adding lipase to food?

1. Dosage control Add strictly according to the prescribed dosage to avoid excessive or insufficient dosage affecting food quality and effect. 2. Temperature and pH conditions Understand the temperatu

What are the methods of using lipase?

1. Direct addition method Add an appropriate amount of lipase preparation directly to food or reaction system. This is the most common and simple method, but the amount of addition needs to be accurat

What effects does the use of lipase have on the taste and quality of food?

1. Improve taste Increase the crispness of food: In baked foods, such as biscuits and shortbread, the appropriate use of lipase can decompose part of the fat, produce small molecules, and make the foo

How to store lipase to extend its shelf life?

1. Low temperature storage Lipase is usually stored in a refrigerator at 2 - 8℃, or in a freezing environment at a lower temperature (such as -20℃ or -80℃). Low temperature can significantly reduce th

How to judge the quality of a lipase?

1. Enzyme activity Enzyme activity is a key indicator to measure the quality of lipase. Higher enzyme activity means that it can more effectively catalyze the hydrolysis reaction of fat under the same

What is the shelf life of lipase?

The shelf life of lipase is affected by many factors, such as product purity, storage conditions, production process, etc. Generally speaking, under appropriate storage conditions (such as low tempera

What are the methods for producing lipase?
