Description

A kind of preparation method of corn steep liquor
Technical field
The invention belongs to technical field of agricultural product process, be specifically related to a kind of preparation method of corn steep liquor.
Background technology
Corn is grass family Zea annual herb plant; Fresh corn contains abundant nutriment, such as protein,Calcium, glutathione, cellulose, magnesium, selenium etc. Lecithin, linoleic acid and vitamin E contained in corn are collaborative, can prevent coronary diseaseThe old sufferers such as disease, cell ageing, vascular sclerosis and cerebral functional deterioration; Contained lutern, that zeaxanthin can resist eyes is oldChange, prevent old ARM, energy Stimulation of The Brain cell, strengthens memory simultaneously; Contained glutathione and selenium are collaborative, generate paddyThe sweet peptide oxidizing ferment of light, has the function of renewing one's youth, delaying senility; The contained nutriment of maize point has the human body of enhancing newly oldMetabolism, adjustment nervous function, and make skin delicacy smooth, suppress, delay wrinkle and produce. So corn is desirable dietotherapyHealth products. But the storage period of fresh corn is shorter, in order to extend storage life majority, corn is dried to storage, its nutritional labeling is beaten greatlyDiscount. In existing corn steep liquor preparation process, will after corn peeling, directly pull an oar, absorption rate is lower, and maize peelIn contain high fiber, starch and protein, caused the waste of resource.
Summary of the invention
The problem existing for prior art, the invention provides the preparation of the corn steep liquor of a kind of corn after germination treatmentMethod, the method has farthest been preserved corn nourishment value, extends storage life.
The technical scheme that the present invention adopted is to achieve these goals:
The preparation method who the invention provides a kind of corn steep liquor, comprises the steps:
(1) pretreatment of raw material: choosing fresh corn grain, add corydalis tuber extract, soak 2h, is 25-28 in temperature after pulling outDEG C, humidity is to germinate under 80-85% condition, in the time that bud length is 0.5-1mm, clear water rinses;
(2) cold fragmentation: germination iblet is added to the water fragmentation of 20 DEG C of temperature <, obtain thick corn steep liquor;
(3) heating gelatinization: thick corn steep liquor is heated to 80-90 DEG C, and is delivered to slaking tank insulation storage 30-60min and makes pasteChange;
(4) enzymolysis: after gelatinization, thick corn steep liquor is cooled to 50-55 DEG C, adds 10-80ppm beta amylase, insulation enzymolysis;
(5) making beating: by thick corn steep liquor making beating after enzymolysis, cross 1.5mm sieve, then pull an oar for the second time, cross 0.8mm sieve, obtain carefullyCorn steep liquor;
(6) homogeneous sterilizing: thin corn steep liquor is used to homogenizer homogeneous, filling and get final product after sterilizing.
Further, described corydalis tuber extract adopts following methods to be prepared from:
(1) 8 parts of corydalis tubers are added to 50 parts of water, 25min is boiled in heating, is cooled to 38 DEG C after filtration, obtains filtrate;
(2) 0.8 part of ascorbyl palmitate is dissolved in ethanol, then adds in above-mentioned filtrate, stir.
Further, described ethanol is 4.5mL/g with the liquid ratio of ascorbyl palmitate.
Further, in corn steep liquor preparation process (2), the addition of described water is 1-2 times of germination iblet weight.
Further, the time of described enzymolysis is 30-60min.
Further, the pressure of described homogenizer homogeneous is 45MPa.
Further, described sterilizing for to be incubated 30-120s at temperature 110-120 DEG C.
The present invention is first creationary carries out germination treatment by iblet while preparing corn steep liquor, although corn nutritive valueHeight, but protein quality is not good enough, human body is low to its digestibility, and amino acid imbalance in corn, and lysine, tryptophan containAmount is obviously not enough, and after germination treatment, its lysine and tryptophane can obviously improve, protein digestibility, water-solubleProperty cellulose and calcium content are improved, after germination treatment, and corn epidermis expansion attenuation, corn steep liquor viscosity prepared by the later stage is fallenLow, improve its energy density. Corn soaks through corydalis tuber extract in advance, the collaborative ascorbic acid of fumaric acid wherein containingPalmitate, can suppress the generation of mould in corn germination process, thereby improve the quality of products.
Advantage of the present invention is:
(1) the present invention is germinateed corn and enzymolysis Combined Treatment in advance, the corn steep liquor comprehensive nutrition of preparation, soluble proteinContent has improved 2-3 doubly, and digestibility is high, delicate mouthfeel;
(2) storage life limit for length, good stability, is easy to store and transport.
