preparation example Construction

[0043] As a third aspect of the present invention , the present invention provides a preparation method of soy sauce, said preparation method comprising the step of preparing fermented seeds and the step of preparing soy sauce with said fermented seeds;

[0044] The step of preparing the fermented seeds comprises: inoculating the Aspergillus oryzae species into the fermentation medium of the Aspergillus oryzae species and cultivating to prepare the fermented seeds.

[0045] In one example, the culture conditions include adopting the following gradient culture method: first culture at 26°C-34°C for 23h-27h, then at 35°C-37°C for 8h-12h, and then at 25°C-32°C for 33h -37h.

[0046] As far as the culture gradient of the present invention is “cultivated at 26°C-34°C for 23h-27h”, the temperature of the culture gradient can be selected from, including but not limited to, the following values ​​or ranges between: 26°C, 26.5°C, 27°C , 27.5°C, 28°C, 28.5°C, 29°C, 29.5°C, 30°C, 30.5...

Embodiment 1

[0052] 1. Raw material pretreatment

[0053] (1) Bran pretreatment: the fineness of the bran is controlled at 20 mesh sieves and the proportion of the under-sieve is 30% (by weight).

[0054] (2) Pretreatment of crop straw: mixed crop straw powder (m 稻草秸秆粉 :m 小麦秸秆粉 =1:1) The fineness is controlled at 40% (weight ratio) under the 20 mesh sieve.

[0055] (3) corn flour pretreatment: the fineness of corn flour is controlled at 25 mesh sieve ratio is 65% (weight ratio).

[0056] 2. Cultivation of Aspergillus oryzae strains for soy sauce fermentation

[0057] (1) Preparation of culture medium for Aspergillus oryzae

[0058] The pretreated bran and mixed crop straw powder (m 稻草秸秆粉 :m 小麦秸秆粉 =1:1), soybean protein, bean dregs, and corn flour are respectively 45%, 20%, 4%, 16%, and 15% according to the weight ratio. After weighing and mixing the dry material, the dry material is obtained according to the weight ratio: Water=1:1.2 ratio, stir evenly, dispense into Erlenmeyer flas...

Embodiment 2

[0062] 1. Raw material pretreatment:

[0063] (1) Bran pretreatment: the fineness of the bran is controlled at 20 mesh sieves and the ratio of the under-sieve is 40% (by weight).

[0064] (2) Pretreatment of crop straw: mixed crop straw powder (m 稻草秸秆粉 :m 小麦秸秆粉 =1:1) The fineness is controlled at 30% (weight ratio) of 20-mesh sieve.

[0065] (3) corn flour pretreatment: the fineness of corn flour is controlled at 25 mesh sieves and the proportion is 85% (weight ratio).

[0066] 2. Cultivation of Aspergillus oryzae strains for soy sauce fermentation

[0067] (1) Preparation of culture medium for Aspergillus oryzae

[0068] Mix the pretreated bran and crop straw powder (m 稻草秸秆粉 :m 小麦秸秆粉 =1:1), soybean protein, bean dregs, and corn flour are respectively 35%, 22%, 6%, 19%, and 18% according to the weight ratio. After the dry material is weighed and mixed, the dry material is obtained according to the weight ratio: Water=1:1.2 ratio, stir evenly, dispense into Erlenmeyer fl...

Abstract

The invention relates to an aspergillus oryzae fermentation solid material, an aspergillus oryzae strain culture medium and a preparation method and application of the aspergillus oryzae fermentation solid material. The aspergillus oryzae fermentation solid material comprises the following components in percentage by weight: 30%-50% of bran, 15%-25% of crop straws, 2%-8% of soybean protein, 10%-20% of bean dregs and 10%-20% of corn flour; the crop straw comprises rice straw and wheat straw. Compared with the prior art, the method has the following beneficial effects that two agricultural and sideline product resources including the rice straw and the wheat straw are effectively recycled, resource waste and environmental pollution caused by incineration or discarding of the agricultural and sideline product resources are avoided, and the method is economical and environmentally friendly. The rice straw and the wheat straw are added, so that the problem of unstable quality of aspergillus oryzae strains caused by influence on normal respiratory metabolism of aspergillus oryzae due to poor air permeability of a traditional culture medium is solved.

Description

technical field [0001] The invention belongs to the field of soy sauce brewing, and in particular relates to aspergillus oryzae fermentation solid material, aspergillus oryzae strain culture medium and a preparation method and application thereof. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. [0003] A large amount of rice straw and wheat straw are produced in agricultural production. How to effectively use these rice straw and wheat straw is very important for environmental protection and rational use of resources. At present, there is n...
