Embodiment 1

[0015] 1. Take out the pearl oyster meat frozen at -18°C, melt it at room temperature, remove impurities, wash it, add water to boil for 5 minutes, remove it, and let it semi-dry. Repeat the 12000r / min 5 times with the pearl oyster meat in a tissue pounder, and pound it into a slurry every time for 5 minutes, then measure the volume and weigh it.

[0016] 2. Add 5 times the amount of liquid carbon dioxide according to the volume of the pulpy pearl oyster meat and stir evenly for supercritical extraction. The supercritical extraction conditions are: pressure 24~26×10 6 Pa, temperature 50°C, time 3 hours.

[0017] 3. After the supercritical extraction of the pearl oyster meat slurry, add 5 times the weight of water and stir evenly. Stir continuously at 240-300r / min to form a cloudy liquid. After heating to 50°C, keep the temperature constant.

[0018] 4. Add 6,000 activity units of alkaline protease per gram to the turbid liquid at a constant temperature of 50° C. according to...

Embodiment 2

[0027] 1. Wash the live pearl oyster, cut open and take the meat, add water and boil for 5 minutes, take it out, and let it dry. Take a certain weight of pearl oyster martensii meat and repeat it 5 times in a tissue pounder at 12000r / min, pound it into a slurry for 5 minutes each time, measure the volume, and weigh it. All the other are with embodiment 1.

Abstract

The invention provides a method for producing Pinctada martensii meat antihypertensive functional nutrient solution. The method comprises the following steps: after Pinctada martensii meat is boiled with water, the meat is dehydrated and smashed into pulp; the pulp is added to liquid carbon dioxide according to volume to carry out supercritical extraction to remove fishy smell; the pulp is stirred uniformly with water according to the weight of the Pinctada martensii meat pulp; the pulp is quickly heated up and boiled to inactivate enzyme after alkali protease is added for enzymolysis, and is quickly heated up and boiled to inactive enzyme after trypsin is added for enzymolysis; aqueous solution is centrifugally collected, and is filtered by a reverse osmosis membrane; and filtrate is collected and concentrated in vacuum, and is diluted by deionized water to be appropriate, and a proper amount of cane sugar is added to the filtrate to prepare the product. The method can produce the antihypertensive functional nutrient solution in batch by using the Pinctada martensii meat which is leftovers in pearl manufacture serving as a main raw material, and the product has pure taste, simple process, short production period, large output, low cost, high economic benefit and obvious antihypertensive effect.

Description

technical field [0001] The invention relates to a production method of pearl oyster martensii meat antihypertensive functional nutrient solution, which belongs to the technical field of health food production. Background technique [0002] At present, there are 160 million hypertensive patients in my country. Hypertension in my country is characterized by high morbidity, high disability, high mortality, low awareness, low diagnosis and treatment, and low control. Therefore, the treatment and prevention of hypertension is an important topic in today's society. Angiotensin-converting enzyme plays a key role in blood pressure regulation. Angiotensin I, which has no pressor activity in the human body, is converted into angiotensin II under the action of angiotensin-converting enzyme, which stimulates vasoconstriction to increase blood pressure, and also It can promote the secretion of aldosterone and further increase blood pressure. The study found that a class of small pepti...
