Benefits of technology

In this patented method called New Horizons (Hoicobi), there was an improvement over previous methods by replacing certain parts or materials altogether instead of just one material used. It also improved productivity compared to existing processes due to its ability to produce high yields from raw grains without causing any harmful substances like bacteria. Additionally, it reduces environmental concerns because no waste products were generated when producing these types of crops through conventional techniques such as open pit farming. Overall, this innovative technology improves food safety while maintaining better taste budgets.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency of producing yeast extract from grain sources such as rice or wheat through fermentations processes involving different types of fungal cells called germinaires. These techniques involve culturing specific type of molds on solid substrate like cereals, which allows them to produce alcoholic liquid products faster than existing methods without causing harmful effects upon their health.

Embodiment 1

[0036] as attached figure 2 Shown, a kind of novel Hanoi white koji production technique of the present invention comprises following processing steps:

[0037] 1) Activation on test tube slant: inoculate the Hanoi alba koji on the sterilized test tube slant medium for activation, control the activation condition at 35°C for 4 days, and use it as the first-generation koji variety, wherein the test tube slant medium adopts 7 % malt juice agar medium, controlled sterilization conditions: 121°C, 40 minutes;

[0038] 2) Expansion culture of bran triangular flask: mix bran and water according to the mass ratio of 1:1 to make bran triangular flask culture medium, according to the proportion of 30g bran triangular flask culture medium per 500mL bran triangular flask, Divide into 500mL triangular flasks of glutinous rice, sterilize at 121°C for 25 minutes, shake up while hot and cool down, inoculate the first-generation koji species obtained in step 1) at an inoculation volume of 0....

Embodiment 2

[0054] A kind of novel Hanoi white koji production technique of the present invention comprises following processing steps:

[0055] 1) Activation on test tube slant: inoculate Hanoi alba koji on a sterilized test tube slant medium for activation, control the activation condition at 34°C for 5 days, and use it as a first-generation koji variety. Among them, the test tube slant medium adopts a sugar content of 8 % malt juice agar medium, controlled sterilization conditions: 123°C, 42 minutes;

[0056] 2) Expansion of the bran triangular flask: mix the bran and water according to the mass ratio of 1:0.8 to make the bran triangular flask culture medium, according to the ratio of 35g bran triangular flask culture medium per 500mL bran triangular bottle, Divide into 500mL triangular flasks of glutinous rice, sterilize at 123°C for 35 minutes, shake up while hot and cool down, inoculate the first-generation koji species obtained in step 1) at an inoculation volume of 0.05% by volume...

Embodiment 3

[0064] A kind of novel Hanoi white koji production technique of the present invention comprises following processing steps:

[0065] 1) Activation on test tube slant: Inoculate Hanoi alba koji on a sterilized test tube slant medium for activation, control the activation condition at 38°C for 4.5 days, and use it as the first-generation koji species. Among them, the test tube slant medium adopts Brix 10 % malt juice agar medium, controlled sterilization conditions: 125°C, 45 minutes;

Abstract

The invention provides a novel aspergillus candidus production process and belongs to the field of brewing bran starter production processes. The novel aspergillus candidus production process is mainly characterized in that 1), for the first time, liquid seeds are adopted to replace three-stage solid seeds in conventional thick-layer ventilation starter making processes, and three generations of starter seeds are cultivated in a closed liquid seed tank, so that the problem that the three-stage solid seeds are prone to bacterial infection and the problem that made starter is impure and non-prominent in flavor are solved fundamentally; 2), a pot-type bran starter cultivator is adopted to replace a ventilation starter tank, and temperature and humidity in the cultivation process of aspergillus candidus are controlled accurately in an airtight environment, so that aspergillus candidus is enabled to be uniform in growth tendency, the made starter is snowy white in color and prominent in flavor, and saccharifying power is 2-3 times that of the thick-layer ventilation starter making processes; 3), for the first time, wind power delivery equipment is applied in the brewing bran starter production processes, so that the problem of difficulty in long-distance conveying of solid materials is solved; the wind power delivery equipment is matched with stemming equipment, cultivating equipment, smashing equipment and drying equipment for use, so that labor intensity is lowered greatly, and mechanized production of brewing bran starter is realized.
