Abstract

The invention provides a preparation method for single cream hydrolysate. The preparation method comprise a step of subjecting homogenized single cream to enzymatic hydrolysis, wherein hydrolase for enzymatic hydrolysis comprises lipase and phosphatidase, and the activity units of lipase and phosphatidase for hydrolysis of each 100 kg of the single cream are 2.3 * 10<5> to 2.3 * 10<7>, and 5.25 * 10<5> to 5.25 * 10<7>, respectively. Through combined action of lipase and phosphatidase, an enzymatic hydrolysis speed is increased, and output efficiency of flavor components is high. The invention further provides a dairy product prepared from the single cream hydrolysate and a preparation method thereof.

Description

technical field [0001] The invention relates to a method for preparing a cream hydrolyzate, in particular to a method for preparing a cream hydrolyzate capable of producing aroma efficiently, a dairy product added thereto, and a method for preparing a dairy product. Background technique [0002] The aroma of milk products is affected by heat treatment during processing and the composition of milk components, which greatly reduces the aroma, aftertaste and freshness of milk, especially skimmed and partly skimmed milk, due to the reduction of fat, the taste is thinner, Not enough milk flavor. The difference in the taste of different milks is firstly caused by the difference in the content of aroma substances. In liquid milk products, the adsorption of aroma compounds by fat is the main mechanism of aroma retention. [0003] Through the enzymatic hydrolysis of lipase, the triglyceride in milk fat can be enzymatically hydrolyzed. Saturated and unsaturated fatty acids, keto aci...
