Abstract

The invention discloses a method for lowering the content of deoxynivalenol of soy-sauce hard liquor. According to the method, the aim of remarkably lowering the content of deoxynivalenol of soy-sauce hard liquor is achieved through mixing flour of weight which is 10-50% of the weight of cooked soybeans or bean meal, strains of weight which is 0.1-0.6% of the weight of the cooked soybeans or bean meal and soybean active peptide of weight which is 0.01-0.1% of the weight of the cooked soybeans or bean meal with the cooked soybeans or bean meal and carrying out liquor making. The method has the advantages that the existing liquor making processes are not changed, and the content of deoxynivalenol of soy-sauce hard liquor can be remarkably lowered by 23-36%.

Description

A kind of method that reduces deoxynivalenol in sauce daqu
Technical field
The present invention relates to food fermentation technical field, be specifically related to a kind of method that reduces deoxynivalenol in sauce daqu.
Background technology
Soy sauce is China's traditional condiment, and the history of existing more than 2000 year, due to its unique flavour and local flavor, has now become one of flavouring indispensable on international market so far.China's high-salt dilute soy has higher edible safety, but its production process adopts multiple-microorganism to carry out solid-state and liquid spontaneous fermentation, therefore,, except physics, chemistry and the biologic contamination introduced by raw material, also exist many distinctive potential safety hazards.
Deoxynivalenol, is a kind of category-B trichothecene, has obvious cytotoxicity, embryotoxicity and teratogenesis.Deoxynivalenol generally pollutes the cereal crops such as wheat, corn, soybean, be considered to one of main natural toxin being present in head blight Wheat and barley, united state food and agricultural organization and the World Health Organization are defined as the most dangerous abiogenous food contaminant together with aflatoxin.Because the primary raw material of soy sauce is soybean and wheat, so deoxynivalenol can enter in finished product by raw material.At present, the degraded of deoxynivalenol mainly contains physics, chemistry and biology method.Wherein, Physical comprises cleaning, heating, ultrasonic wave, absorption etc.; Chemical method and biological methods all need additional chemical substance or microorganism.Because sauce daqu needs further fermentation, therefore should not adopt the physics methods such as cleaning.Meanwhile, chemical residual may affect soy sauce color, mouthfeel, and brings potential food-safety problem.Therefore, seek elimination or the biodegrading process of mycotoxin in effective soy sauce production process, improve the edible safety of soy sauce, for ensuring food safety and promoting economic development, tool is of great significance.
Summary of the invention
The object of this invention is to provide a kind of method that reduces deoxynivalenol in sauce daqu.
Of the present inventionly a kind ofly reduce the method for deoxynivalenol in sauce daqu and comprise: after 10% ~ 50% the flour, 0.1% ~ 0.6% bacterial classification, 0.1% ~ 0.6% the Soybean Peptide that are equivalent to soybean or dregs of beans weight are mixed, be evenly distributed on after boiling on soybean or dregs of beans and carry out making leaven of soy sauce.
In said method, described koji-making condition is: 1 ~ 4 day koji time, 25 ℃ ~ 35 ℃ of temperature, relative humidity 60% ~ 100%.
Described Soybean Peptide is prepared by the following method: soybean protein isolate with water with 1:7 ~ 1:9(w/w) ratio mixes, and 45 ~ 50 ℃, adopts papain or compound protease to be hydrolyzed under the condition of pH6.0 ~ 8.0; When degree of hydrolysis reaches 10% ~ 15%, enzyme goes out; Centrifugal, get supernatant; Supernatant is crossed the milipore filter of 3000 u, and filtrate freeze-drying obtains Soybean Peptide.
In above-mentioned preparation method, described in the enzyme bar that goes out be 90 ℃ ~ 100 ℃, keep 10 ~ 15min.
In above-mentioned preparation method, described centrifugal condition is 9000 ~ 10000r/m, centrifugal 10 ~ 15min.
In above-mentioned preparation method, the biologically active peptide that described molecular weight concentrates on 100 ~ 2000u accounts for the more than 70% of total nitrogen.
The present invention compared with prior art has the following advantages:
1, the present invention be take soybean protein isolate as raw material, by controlled enzymatic hydrolysis, obtains Soybean Peptide, and raw material sources are abundant, and product has no significant effect yeast making process.
2, the present invention is by adding biologically active peptide in yeast making process, promoted aspergillus oryzae propagation and metabolism, suppressed varied bacteria growing, under limited process conditions, significantly reduced Daqu in deoxynivalenol content.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is described further.
embodiment 1
1, soybean protein isolate and water 1:7(w/w) mix, at 50 ℃, under pH6.5, with papain hydrolysis to degree of hydrolysis, be 12.5%, 95 ℃ and keep the 12min enzyme that goes out, the centrifugal 15min of 9000r/m, gets supernatant; Supernatant is crossed the milipore filter of 3000u, and gained soybean active peptide molecular weight concentrates on 100 ~ 2000u, accounts for 75.0% of soybean protein isolate total nitrogen.
2, with the weighing scale with respect to soybean, after the Soybean Peptide of 50% flour, 0.3% bacterial classification (Shanghai makes 3.042) and 0.1%, 0.3%, 0.6% is mixed respectively, being evenly distributed on the soybean after boiling, is 25 ℃ in temperature, under the condition of relative humidity 60%, koji is 3 days, obtains sauce daqu.As shown in Table 1, Cheng Quzhong deoxynivalenol content has reduced by 23.9% ~ 36.9% with respect to the control group that does not add Soybean Peptide.
?
embodiment 2
1, soybean protein isolate and water 1:9(w/w) mix, at 50 ℃, under pH8.0, with composite protease hydrolysis to degree of hydrolysis, be respectively 10.4%, 12.8% and 14.9%, 90 ℃ and keep the 15min enzyme that goes out, 10000r/m, centrifugal 10min, gets supernatant; Supernatant is crossed the milipore filter of 3000u, and gained soybean active peptide molecular weight concentrates on 200-2000u, accounts for respectively 74.5%, 76.2% and 78.4% of soybean protein isolate total nitrogen.
2, with the weighing scale with respect to soybean, after 10% flour, 0.1% bacterial classification, 0.3% above-mentioned Soybean Peptide are mixed, be evenly distributed on after boiling on soybean, 30 ℃ of temperature, under relative humidity 90% condition, koji is 2 days, obtains sauce daqu.As shown in Table 2, Cheng Quzhong deoxynivalenol content has reduced by 30.0% ~ 33.9% with respect to the control group that does not add Soybean Peptide.
