Abstract

The invention provides a method for preparing nutritional natto. The method comprises the steps of screening and washing soybeans; soaking the washed soybeans; steaming the soaked raw material soybeans at a high temperature to get cooked soybeans; inoculating the cooked soybeans with natto strain and then sub-packaging; putting the sub-packaged cooked soybeans into a fermentation chamber, wherein the temperature of the fermentation chamber is 55-70 DEG C; controlling the temperature to drop to 40-55 DEG C and keeping the temperature for 7 h; rising the temperature from 40-55 DEG C to 45-60 DEG C, keeping the temperature for 4 h; lowering the temperature from 45-60 DEG C to 0-5 DEG C, and keeping the temperature for 8h to get a semi-finished product; sub-packaging the semi-finished product and adding flavoring bags, and then performing external packaging to get a finished product, and then putting the finished product into a freezer for cold storage. According to the method provided by the invention, as the production process flow and the independently researched and developed new fermentation process are optimized, more shredded natto with high nutrition value can be prepared, thus, the demand for good appearance is met, and meanwhile, the original nutrition value of natto is stored, thus, market promotion is facilitated.

Description

A kind of preparation method of nutritious natto
Technical field
The invention belongs to food fermentation and food processing field, be specifically related to a kind of natto preparation method with the high nutrition of Donna beans silk.
Background technology
Natto, China Han traditional zymotic bean product, be one of important flavoring of many styles of cooking, its raw material are soya bean, the title that soya bean has " kings in beans ", and be called " Vegetable meat ", " green cow " by people, nutritive value is the abundantest.Containing the protein about 40% of high-quality in dry soya bean, it is the hat of other grains.Modern nutriology research shows, one jin of soya bean is equivalent to thin pork more than two jin, or three jin of eggs, or the protein content of 12 jin of milk.Fat content also accounts for first place in beans, and oil yield reaches 20%; In addition, also containing mineral matters such as vitamin A, B, D, E and calcium, phosphorus, iron.Containing irony 55 milligrams in one jin of soya bean, and the utilization that is easily absorbed by the body, very favourable to hypoferric anemia; In one jin of soya bean phosphorous 2855 milligrams, very favourable to cerebral nerve.Various bean product after soya bean processing, not only protein content is high, and can not synthesize and essential amino acid containing multiple human body, and in cholesterol level, the protein digestibility of bean curd is up to 95%, is the product of desirable dietetic treatment.
Natto system high protein nourishing food, the alcohol element contained in natto, acidifying type lipid in part cholesterol, decomposer can be got rid of in body after edible, abnormal blood pressure is made to recover normal (" health science " magazine in January, 1994 number, comment society of Japan publishes, the 4th page), and natto has whole intestines effect, and easily digesting, is extraordinary garnishes.
But there is certain shortcoming in natto, the first, the original distinctive local flavor of natto and smell, as very much corrupt food, taste is slightly smelly, makes many consumers be difficult to accept, especially female consumer; Second general rapid-result natto is difficult to the natto silk forming high nutrition, makes some consumers always can not be very satisfied to this, is difficult to form strong consumption dynamics always, annoyings businessman.
Summary of the invention
Based on this, the present invention have developed a kind ofly to be had unique zymotechnique and can produce the natto food enriching natto silk, and a kind of preparation method of nutritious natto comprises the following steps:
Step one: screening cleaning soybean, selects material bean;
Step 2: soak, soaked by the described material bean after screening cleaning, the time is 12-24 hour;
Step 3: the described material bean after immersion is carried out thermophilic digestion and obtains ripe beans;
Step 4: by packing after described ripe beans inoculation natto bacterial classification;
Step 5: the described ripe beans after packing are put into fermenting cellar, described fermenting cellar temperature is 55-70 degree Celsius, and control temperature drops to 40-55 degree Celsius, maintains 7 hours; Be increased to 45-60 degree Celsius from 40-55 degree Celsius, maintain 4 hours, be reduced to 0-5 degree Celsius from 45-60 degree Celsius, maintain 8 hours, obtain semi-finished product;
Step 6: carry out external packing after described semi-finished product packing is added flavor pack and obtain finished product, more described finished product is put into freezer refrigeration.
Wherein, soybean described in described step one carries out screening cleaning by screening cleaning machine, and described screening scavenging period is 20 minutes.
Wherein, in described step 2,12-13 hour under 20 degrees Celsius of water temperature condition, 18-19 hour under 15 degrees Celsius of water temperature condition, 23-24 hour under 10 degrees Celsius of water temperature condition.
Wherein, in described step 3, digestion process is:
A, by soak after soybean drain;
B, the soybean after draining is carried out steam boiling;
C until described in drain after soybean completely well-done.
Wherein, in digestion process, steam pressure 0.12-0.13pma, temperature is 105 degrees Celsius, 30 minutes time.
Wherein, receiving beans bacterial classification to be gemma hay bacillus in described step 4, is 20-30PPM by kind of amount.
Wherein, in described step 6, packing every part is 50g or 40g.
The present invention is compared with original technology:
1., by optimized production process and process, reduce high temperature Production Time, save the nutritive value of natto self.
2. by special sweat, eliminate natto stink, new product natto has unique local flavor, adapts to Chinese popular diet taste custom, is convenient to promote on a large scale.
3., by new-type sweat, high/low temperature combining with fermentation mode makes it possible to pull out more more nutritious natto silks, meets requirement that is attractive in appearance and nutrition, is beneficial to popularization.
Detailed description of the invention
Below describe and specific embodiment of the invention scheme is shown fully, to enable those skilled in the art to put into practice them.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.The scope of embodiment of the present invention comprises the gamut of claims, and all obtainable equivalent of claims.
New-type zymotechnique has high nutrition, enriches a preparation method for the natto of natto silk, comprises the following steps:
Step one: screening cleaning soybean, to clean material bean, decontamination work, filters out the material bean of full grains, free from insect pests;
Step 2: soak, described material bean after screening cleaning is soaked, make the abundant imbibition of material bean, according to water temperature, soak time is 12-24 hour, is taken out by the material bean after soaking, and then rinses slowly the material bean after immersion with clear water, prevent the integrality destroying material bean, wash away immersion foreign material out, dust;
