Abstract

The present invention relates to a method for the preparation of liquid pearls from solid pearls, particularly to a biochemistry method for the preparation of liquid pearls from solid pearls, which mainly solves the problem of the hard solubility of the pearls. The present invention hydrolyzes non-soluble hard shell protein in the pearls into soluble hard shell protein by the catalyzing and hydrolyzing action of enzyme. The biochemistry method for the preparation of liquid pearls from solid pearls comprises the following steps: pearls are pulverized to 60 meshes; the parts of the pearls comprising inorganic salt are dissolved in hydrochloric acid or phosphoric acid and are filtered, and filter liquid is used for stand-by application; the non-soluble parts of the pearls are washed to neutrality by water and are also ground into mixed suspension liquid; 0.1 to 0.5% of papain is added, and an enzyme catalysis reaction is carried out in the temperature of 50 to 65 DEG C; hydrolysate is formed by filtration, and the remained inorganic salt parts and the hydrolysate are prepared into liquid pearls with different concentrations.

Description

Method for preparation of liq. pearl from solid pearl

The present invention relates to a kind of biochemical method that changes liquid pearl by the solid pearl into.

Before the present invention proposes, pearl mainly be with form of powder for using because contained composition is the insoluble composition in the pearl, so theoretically, the nutrition of pearl bioavailability in vivo is restricted.In recent years along with research to pearl, people attempt to prepare liquid pearl by hydrolysis method, usually the method that adopts is acid hydrolysis, basic hydrolysis, enzymic hydrolysis, wherein acid hydrolysis, the basic hydrolysis meeting is damaged the nutrition of part pearl, and corrosion production unit, contaminate environment, these system shortcomings are restricted its application, enzyme process prepares amino acid, biggest advantage is not destroy the amino acid composition, and enzymolysis product need not to carry out special processing, mild condition in the suitability for industrialized production, equipment is simple, do not have three-waste pollution etc., extract protein hydrolystate (seeing Chinese patent CN86108557) as Zhang Gongqin of university of Tongji University etc. with enzyme from proteinaceous waste material, the luxurious Jiang Yong of Nanning monosodium glutamate etc. extract nutrition (seeing Chinese patent CN86108878) etc. with enzyme from pollen, all be that comparatively satisfied enzyme process prepares amino acid whose example, but do not see as yet that so far the method for preparing the pearl amino acid composite liquid with enzyme process is arranged.

The objective of the invention is to utilize the catalytic hydrolysis effect of enzyme, the solid pearl is prepared into liquid pearl, make the scleroprotein in the pearl change aqueous nutrition into, to improve the biological utilisation effect of pearl.

The present invention realizes by following method, it is the catalytic hydrolysis effect that utilizes enzyme, contained insoluble duricrust proteolysis in the pearl is become easily being absorbed by the body and multiple amino acids of solubility, its concrete grammar is, earlier with the pearl raw material through tentatively being crushed to 60 orders, add 2 times of amount hydrochloric acid or phosphoric acid dissolving, make the filtrate for later use of contained inorganic salt part in the pearl; Insoluble part is to be washed to neutrality, put and grind to form even suspension in the colloidal mill, the papoid that adds 0.1-0.5%, carried out under the neutral environment of 50-65 ℃ of temperature enzymic catalytic reaction 1-2 hour, and filtered then, filtrate partly is the pearl amino acid hydrolyticsolution, the filtrate that contains the inorganic salt part that to leave and take simultaneously, look its purposes, quantitatively join in the pearl amino acid hydrolyticsolution, make it to form the liquid pearl of different concns.

Outstanding advantage of the present invention is the main active ingredient that has more intactly kept pearl, make human body be easy to each seed amino acid composition in the absorption liquid corpse pearls, for preparation is that the series oral liquid and the exterior-applied article of main raw material provides easy with the pearl, the method of easy row, this processing method need not special producing equipment in addition, simple to operate, safety, production cycle shorten greatly than acid-hydrolysis method, and have better effect.

The embodiment of the invention:

In the container that a band stirs, add pearl meal (60 order), slowly add hydrochloric acid, with adding with stirring, the ratio that adds acid is a pearl powder; Acid=1: 2～3 (w/w).Filter then, put and fling to acid gas in the Fume Hoods, the gained residue is a pearl inorganic elements part, other usefulness of purchasing; Filter residue partly moves in the reactor, add 10 times of water gagings, 0.2% papoid is in the environment of pH7,55 ℃ of attemperation, carry out enzyme digestion reaction 60 minutes, and filtered, discard filter residue, collect filtrate and be the Margarita hydrolyzed solution that contains multiple amino acids, the inorganic salt part that to before continue to employ looks its purposes quantitatively to join in the amino acid hydrolyticsolution again, promptly gets the liquid pearl of different concns.

Claims

A kind of method for preparing liquid pearl by the solid pearl, it is characterized in that earlier pearl raw material pulverizing to 60 order, add 2 times of amount hydrochloric acid or phosphoric acid solution, make that contained inorganic salt are partly dissolved in the pearl, filter then, leave and take the filtrate for later use that contains the inorganic salt part, insoluble part adds the water flushing to neutral, put and grind to form even suspension in the colloidal mill, add the papoid of 0.1-0.5%, in the neutral environment of 50-65 ℃ of temperature, carried out enzymic catalytic reaction 1-2 hour, filter then, filtrate partly is the pearl amino acid hydrolyticsolution, again with the standby filtrate of inorganic salt part and the liquid pearl that the pearl amino acid hydrolyticsolution is mixed with different concns of containing.
