Problems solved by technology

Due to the hydrolysis reaction, the product contains a large amount of free fatty acid and monoglyceride, such as: a typical reaction product contains up to 20% of monoglyceride and nearly 20% of fatty acid, if the target product is diglyceride, This method generates a large number of by-products, and the separation of by-products requires a higher cost, and the utilization of by-products is also a problem that needs to be considered, so this method is economically insufficient.

Embodiment 1

[0038] Mix 50g and 100g of dry glycerin and white clay respectively to obtain adsorbed glycerin. Such as figure 1 As shown, the adsorbed glycerin and 1000g of refined rice bran oil are premixed in tank 1, and the mixture of solid adsorbed glycerin and oil is pumped into tank 3 through pump 2, and then 200 g of immobilized lipase Lipozyme TL IM is added at 20°C Under the condition of 60 revolutions per minute, the diglyceride content reached the maximum for 72 hours after the reaction was filtered to remove the immobilized enzyme and glycerin adsorption material in the reaction product, and then the monoglyceride and fatty acid were removed by molecular distillation at 190°C and 1.2 Pa The diglyceride grease was obtained, and the results are shown in Tables 1 and 2.

Embodiment 2

[0040] The temperature is 50°C, the amount of enzyme added is 40g, and the reaction time is 24 hours. The rest is the same as in Example 1. The results are shown in Tables 1 and 2.

Embodiment 3

[0042] Same as Example 1, except that the amount of enzyme added is 80g, the reaction temperature is 40°C, and the reaction time is 28 hours. The results are shown in Tables 1 and 2.

Abstract

The invention relates to a process for preparing diglyceride grease comprising the steps of, (1) adsorbing the glycerine onto adsorption material, (2) mixing the adsorption material obtained in step (1) and glycerine with triglyceride, using immobilization lipolytic enzyme as catalyst for catalyzing the reaction between triglyceride and glycerine at 20-90 deg. C, (3) separation by removing immobilization lipolytic enzyme and glycerine adsorption material from the outcome yield of (2), separating aliphatic acid to obtain diglyceride grease.

Description

Technical field [0001] The invention relates to a production method of diglyceride grease. Background technique [0002] Diglyceride is a fat molecule with only two fatty acid chains. Diglyceride can be used as an emulsifier, fat plasticity improver or as a base for food, medicine, cosmetics, etc. Recent studies have found that the absorption and metabolism modes of diglycerides and triglycerides are different. Diglycerides are easier to be converted into energy and used in the body, while triglycerides are easier to accumulate in the body. Eating fats containing diglycerides has the effect of reducing weight. Therefore, diglyceride fats can be eaten as a healthy fat. [0003] Glycerolysis is a method that uses glycerol and triglycerides to react. Chemically catalyzed glycerolysis has been used in the production of saturated fatty acid monoglycerides and diglycerides, but the reaction needs to be operated at high temperatures, which is more suitable for saturated fatty acids.
