Abstract

A kind of production method of pure malt extract, this method comprises that wheat embryo is put into reactor steeped 2-3 hour with the water logging that is four times in wheat embryo weight, defibrination then, and to regulate pH with NaOH solution after filtering out bits be 7.0-8.0, under 40-50 ℃ of condition continuous stirring 90-100 minute, add food-grade albumen enzyme and food-grade lipase simultaneously, be incubated 40-50 ℃, with the solution-stabilized pH7.0-8.0 of NaOH, behind the enzymolysis 1.5 hours, heat temperature raising to 120 ℃ deactivation sterilization is cooled to 50-60 ℃ then, smart filter, vacuum concentrates, the homogeneous spraying drying powder-forming, the malt extract of making through the inventive method has the contained complete nutrients matter of wheat embryo, and instantly easily is absorbed by the body.

Description

The production method of pure malt extract

The present invention relates to the production method of pure malt extract, particularly relate to the method that contains the pure malt extract of needed by human body nutritional factors with biologic enzymolysis method production.

Malt extract, i.e. the nutrition elite of wheat, this part elite mainly concentrates in the wheat germ.The malt extract raw material of custom address is gone up by society at present, and majority is meant refining flour (the starch part of wheat).Minority is meant makes maltose that generates after the biocatalyst saccharification rice and so on fructus hordei germinatus, be the conversion product of starch, promptly is the maltose composition as the malt extract part of the extract of malt and milk indication sold on the market, is not the nutrition elite of wheat.

In recent years, the food variety of using wheat germ increases gradually, but all still be to adopt the mode of directly wheat germ being made additive to use so far, processing to wheat germ also all is that physical method is as baking, slurry etc. is wasted in pulverizing, the elite of wheat germ is not partly done the decomposition and the purification of further in-depth, and the wheat germ powder of producing with physical method can not be instant, and sediment is arranged.Be not easy to use widely and better absorb with human body.

In order to overcome above-mentioned shortcoming of the prior art, the inventor has proposed a kind of method of producing pure malt extract with enzymatic isolation method through after studying for many years.The pure malt extract of producing with the inventive method has the effect that doubles to concentrate nutrition elite in the wheat germ, and it is instant to have reached malt extract, the purpose of deposit-free.

The flow process of pure malt extract production method of the present invention is as follows: wheat embryo → immersion → defibrination → separating and filtering → enzymolysis → deactivation → essence filter → vacuum concentrates → homogeneous → spray thing drying → packing → product.The production method of pure malt extract of the present invention can not only be produced easy dissolving, and deposit-free also contains the malt extract of abundant nutrition composition, and production method is simple, and is with low cost, is easy to popularize.

The production method of pure malt extract of the present invention be with wheat embryo in having the jacket type reactor of agitator with the little immersion of (by wheat embryo weight) four times 2-3 hour, defibrination then, and with 100 mesh sieve separating and filtering bits, with NaoH solution (10%(is heavy) the NaoH aqueous solution) regulate PH at 7.0-8.0, the logical vapours of chuck is warmed up between 40-50 ℃, continuous stirring 90-100 minute, rotating speed 200-300 rev/min, the amount of pressing every gram protein 100 unit enzyme activities in the wheat germ simultaneously adds the food-grade albumen enzyme, and the amount of pressing the fatty 25 unit enzyme activities of every gram adds food-grade lipase, be incubated 40 ℃ to 50 ℃, and with the solution-stabilized pH value of NaoH at 7.0-8.0, enzymolysis 1.5 hours.After enzymolysis finishes, heat temperature raising to 120 ℃ go out enzyme works, sterilization, be cooled to 50-60 ℃ then, filter with ceramic filter is smart, filter residue reclaims recirculation and concentrates with rising film or downward film evaporator vacuum then, vacuum is 600-720mmHg, and high-pressure homogeneous with homogenizer, pressure is 175 kilograms per centimeter ², spray-dried at last, promptly become the powdery pure malt extract.

With the pure malt extract of the inventive method preparation, dash all dissolvings of back with hot water, leaving standstill does not have precipitation and occurs after 30 minutes, can be instant or as the nutrition fortifier of numerous food, the trophic analysis of pure foster essence the results are shown in Table 1-4.

The complete nutrients matter that contains wheat embryo from table 1-4 as can be seen with the malt extract of method production of the present invention.The nutrition that wheat germ contained from a unit, wherein protein reaches more than 30%, belong to full price albumen, eight kinds of essential amino acid A wide selection of colours and designs, ratio between amino acid quantity also adapts with the needs of human body, limiting amino acid content is abundant, and is higher 1.5 times than egg intensive amount (0.72) as lysine content in the hectogram albumen (1.85 gram).Contain selenium, be very strong antioxidant by its peroxidase of glutathione that the peptide bond condensation forms by glutamic acid, cysteine, glycine; the structure of cell membrane has protection and the old and feeble effect of the cell mass that slows down (neural, cell), and antagonist immunity and sterilizing power have facilitation.

Wheat germ contains the best grease about 12%, wherein about linoleic acid (about 65%) VE(0.52%) height of content, can be rated as the hat that occupies various edible oils.Linoleic acid is an essential fatty acid, and the softening blood vessel effect is arranged, and VE can keep human body normal development function, the vigor of building up health, and delaying cell aging also can be prevented going up the undue in vivo oxidation of unrighted acid and cause canceration, and antitumaous effect is arranged.Paddy alcohol in the 2-6% unsaponifiable matter is provitamin D, mainly is lecithin and cephalin in 2% phosphatide, is the Main Ingredients and Appearance that constitutes brain and nerve fiber.

Wheat germ contains abundant multivitamin, and B, B, B, Yan acid, pantothenic acid, folate content are all very high, choline (410 milligrams/hectogram) inositol (852 milligrams/hectogram) helps brain development and prevent nephrorrhagia, liver function barrier.

Wheat germ contains abundant trace element, as calcium (404 milligrams/hectogram) phosphorus (1018 milligrams/hectogram) iron (30 milligrams/hectogram) zinc (10.08 milligrams/hectogram) potassium (827 milligrams/hectogram) magnesium (336 milligrams/hectogram) etc. all is to constitute tissue and keep normal physiological activity institute essential, especially is fit to the needs that child development is grown up.

Wheat germ contains the total reducing sugar more than 30%, mainly contains dextrin, pentosan etc., easily is absorption of human body.

Through deepening the malt extract after making with extra care, original protein and grease have been done decomposition, are convenient to absorption of human body, vitamin and trace element have all been done concentrating at double, exceeded original content, nutrition is all from natural, and composition is abundant, fully, dietary function is outstanding, adapt to patient and health care needs old, weak, children such as hypertension, liver function barrier, because can be instant, made things convenient for edible, enlarged application, had more characteristics than original wheat germ.

The following examples are to further specify of the present invention.

Embodiment 1
