[0022] A preparation method of goat milk drink containing ACE inhibitory peptide, the steps of the preparation method are:

[0023] Step 1: Cool the reconstituted goat milk to 4°C, use a high-speed centrifuge to centrifuge at 6400 rpm for 15 minutes, remove fat, and obtain skim milk;

[0024] Step 2: heat the obtained skim milk in a constant temperature water bath within the range of 35-75°C, stir with a magnetic heating stirrer at a stirring speed of 0-1600rpm, and add HCl solution dropwise while stirring to make the skim milk solution The pH value is 4.2-5.0, and the casein is precipitated. Use a high-speed centrifuge to centrifuge at 6400 rpm for 15 minutes, discard the supernatant, freeze-dry the precipitated casein, and pre-freeze at -40°C for 12 hours. Then transfer to a freeze dryer and freeze-dry at -55°C for 24 hours to obtain casein freeze-dried powder, and measure the casein yield;

[0025] Step 3: The obtained casein freeze-dried powder is made into a casein solut...

Abstract

A method for preparing a goat milk beverage containing ACE (Angiotensin Converting Enzyme) inhibitory peptide comprises the following steps of: cooling, centrifuging and fatting reconstituted goat milk, thereby obtaining skimmed milk; preparing casein from the skimmed milk by an isoelectric precipitation method, and obtaining polypeptide powder through enzymolysis; and mixing polypeptide powder with reconstituted goat milk, concentrated fruit juice, polypeptide powder, cane sugar, citric acid, beta-cyclodextrin, purified water and the like to obtain the goat milk beverage containing ACE inhibitory peptide. The goat milk beverage containing ACE inhibitory peptide prepared by the method provided by the invention contains the ACE inhibitory peptide and thereby has obvious effect of reducing blood pressure; if the hyperpietic drinks the goat milk beverage for a long time, the blood pressure of the hyperpietic can be reduced; and the goat milk beverage is mild in properties without side effect on people of normal blood pressure; and the goat milk beverage containing ACE inhibitory peptide has various effects of immunological activity, and prompting digestive absorption and losing weight, and the like.

Description

technical field [0001] The invention relates to a method for preparing a drink, in particular to a method for preparing a goat milk drink containing ACE inhibitory peptide. Background technique [0002] With the development of social economy and the gradual improvement of living standards, the proportion of fat and calories in people's diet has increased significantly, and the improvement of mechanization, automation and information technology has gradually reduced people's daily physical activities. However, these It will lead to a rapid increase in the incidence of cardiovascular and cerebrovascular diseases. Cardiovascular disease is mainly coronary heart disease, which is also called coronary atherosclerotic heart disease, and hypertension is an important risk factor for atherosclerosis, and blood pressure level is positively correlated with the risk of cardiovascular disease. The 2010 Chinese guidelines for the prevention and treatment of hypertension pointed out that ...
