Abstract

The invention provides a method for preparing a feed from common andrographis herb dregs by virtue of fermentation. The method comprises the following steps: (1) pretreatment of dregs, namely drying the dregs until the moisture content is 2-5wt% and grinding until the power granularity is within the range of 2.5-10 meshes; (2) preparation of a dreg culture medium, namely mixing 50 parts of dregs with bran in the ratio of 1: 1 to 2: 1, 0.2-0.6 part of corn flour, 0.2-0.6 part of ammonium chloride and 0.1-0.3 part of monopotassium phosphate in 25-50 parts of sterile water, pouring the obtained mixed liquid into a conical flask and mixing evenly to obtain natural pH, and sterilizing at 121 DEG C under high pressure for 20 minutes; (3) dreg fermentation, namely inoculating 10-30mL of the second-level seeds of rhizopus oryzae strain or bacillus subtilis strain into each 100g of dreg culture medium, fermenting at 26-30 DEG C for 48-96 hours, and shaking the culture medium evenly every 12 hours; (4) product treatment, namely drying the culture medium obtained by fermentation, and grinding and sieving by use of a sieve of 2-4 meshes, thereby obtaining the fermented feed product. The method is simple in process, short in time, low in material consumption, advantageous for industrial pilot scale-up, and relatively high in yield.

Description

technical field [0001] The invention relates to a method for preparing feed by fermenting andrographis paniculata dregs, belonging to the technical field of biochemical industry. Background technique [0002] Andrographis paniculata, also known as spring lotus and autumn willow, is an annual herb with a length of 4-8 cm and a width of 1-2.5 cm. Medicinal plants have the functions of clearing away heat and detoxification, reducing inflammation, reducing swelling and relieving pain. Indications for cold and fever, sore throat, aphtha of the mouth and tongue, cough and cough, diarrhea and dysentery, hot stranguria, astringent pain, carbuncle and sore, snake bites. [0003] From the website of the State Food and Drug Administration in 2015, it can be found that there are 14 manufacturers involved in andrographis paniculata, of which 5 produce andrographolide and andrographolide semi-ester extracts. It is known that each production enterprise consumes about 3,000 tons of Androg...
