Abstract

The invention discloses a preparation method of goat milk containing ACE (Angiotensin Converting Enzyme) inhibitory peptide based on Lactobacillus helveticus fermentation. The preparation method comprises the following steps of: vaccinating Lactobacillus helveticus in goat milk or goat milk reconstituted milk, and carrying out anaerobic fermentation at a temperature of 30-40 DEG C for 10-15 hours, so as to obtain fermented goat milk; sufficiently mixing 80-90 parts of the fermented goat milk, 5-10 parts of sucrose, 0.15-0.5 parts of a stabilizer and 5-30 parts of water and then cooling to a temperature below 10 DEG C, so as to obtain mixed fermented goat milk; and sealing the mixed fermented goat milk at a temperature of 2-5 DEG C, and maturating for 8-10 hours so as to obtain the goat milk containing the ACE inhibitory peptide. The prepared goat milk has nutritive values of goat yogurt and specific tastes, and further contains the ACE inhibitory peptide with higher inhibition rate, so that not only can the development and the utilization of the goat milk resources be prompted, but also the goat milk has positive effects on hypertension prevention and nutrition and health care of a patient suffering from hypertension.

Description

technical field [0001] The invention belongs to the technical field of goat milk fermentation, and relates to a method for preparing goat milk containing ACE inhibitory peptides fermented by Lactobacillus helveticus. Background technique [0002] The World Health Organization (WHO) defines hypertension as: systolic blood pressure ≥ 140 mmHg and / or diastolic blood pressure ≥ 90 mmHg when blood pressure is measured three times on different days without using antihypertensive drugs. According to the survey data on nutrition and health status of 270,000 national residents organized by the Ministry of Health in 2010, the prevalence rate of hypertension among people aged 60 and over in my country is 49%, that is, about 1 out of every 2 people over 60 years old. Man suffers from high blood pressure. In recent years, the prevalence of hypertension in children has also increased. According to survey results in some provinces and cities in the past 10 years, the prevalence of hyperten...
