However, pearls have an organic / inorganic hybrid nanostructure. Every two layers of nepheline-structured calcium carbonate (about 200-500 nanometers thick) sandwich a layer of protein and aquifer layers with a thickness of several to a dozen nanometers. The water content is about 2-6%, and pearl protein is shell protein, which is difficult to be digested and absorbed by the human body

Embodiment 1

[0015] 10kg of pearls were pulverized by an ultrafine pulverizer to obtain 9.87kg of pearl powder. Detected with a MASTERSIZER200 laser particle size analyzer, the particle size results of the pearl powder are: d (0.1) 4.355 microns, d (0.5) 9.023 microns, d (0.9) 20.062 microns; Protein 3.2g. Gained pearl powder 9.83kg is mixed with water into 20% turbid liquid.

[0016] Pour the turbid solution into a 100L bioreactor, heat to 45°C, add 8 grams of neutral protease, stir for 4 hours to carry out enzymatic hydrolysis, and then raise the temperature to 100°C to inactivate the enzyme.

[0017] The turbid liquid after hydrolysis was dried with a spray dryer to obtain 9.80 kg of enzyme-hydrolyzed pearl powder.

[0018] Inspection: Take 10g of enzyme-hydrolyzed pearl powder and 100g of water, mix evenly, centrifuge at 1000 rpm, take the supernatant for total protein (amino acid, total polypeptide) detection (Kjeldahl method), get 0.06g of soluble total protein, pearl powder Conta...

Embodiment 2

[0024] 10kg of pearls were pulverized by an ultrafine pulverizer to obtain 9.90kg of pearl powder. Detect with a MASTERSIZER200 laser particle size analyzer, the pearl powder particle size results are: d (0.1) 3.955 microns, d (0.5) 8.822 microns, d (0.9) 19.06 microns, and the pearl powder contained in every 100g of pearl powder is measured by the Nitrogen method. Protein 3.13g. Gained pearl powder 9.85kg and water are mixed with 50% slurry. Then use a small ball mill to wet grind until the average particle size is less than 0.5 micron. Detected with a MASTERSIZER200 laser particle size analyzer, the pearl powder particle size results are: d (0.1) 0.172 microns, d (0.5) 0.365 microns, d (0.9) 0.898 microns.

[0025] Mix the wet-milled pearl powder with water to form a turbid liquid containing 40% pearl powder.

[0026] Pour the turbid solution into a 100L bioreactor, heat it to 50°C, add 10 grams of neutral protease, stir for 6 hours to carry out enzymatic hydrolysis, and ...

Abstract

The invention discloses a preparation method of enzyme hydrolysis pearl powder, comprising the following steps of: superfine pulverizing and wet grinding the pearl until more than 90 percent of the particles have a diameter less than 0.5 micron, mixing the pearl powder with water into turbid liquid, heating the turbid liquid to 40 to 60 DEG C, adding neutral protease for enzyme hydrolysis and enzyme destruction, and drying by spraying to obtain the enzyme hydrolysis pearl powder. The technical method is simple, the proteolysis ratio of the pearl is high, and the special flavour and effective constituent of the pearl powder are maintained to the maximum. The pearl powder can be easily digested and absorbed by a human body, can be easily absorbed by the skin and is applicable to medicine, nutrition and skin-care product as an additive.

Description

technical field [0001] The invention relates to a processing method of pearl powder, in particular to a production method of enzyme hydrolyzed pearl powder. Background technique [0002] Pearl is a kind of precious Chinese herbal medicine, which has the effects of calming the nerves, improving eyesight, detoxification and beauty care. Modern scientific analysis shows that pearls contain nearly 20 kinds of amino acids, more than 20 kinds of trace elements, porphyrin and rich calcium. However, pearls have an organic / inorganic hybrid nanostructure. Every two layers of nepheline-structured calcium carbonate (about 200-500 nanometers thick) sandwich a layer of protein and aquifer layers with a thickness of several to a dozen nanometers. The water content is about 2 to 6%, and pearl protein is shell protein, which is difficult to be digested and absorbed by the human body. [0003] Due to the high hardness and toughness of pearls, processing is very difficult. The current tradit...
