Problems solved by technology

Adopt this method to ferment notoginseng slag to produce protein feed and there are following problems: 1, the accumulation of fermentation metabolites (sugars) has produced repression to the synthesis of various hydrolytic enzymes, and then has influenced thalline growth and each 2. The hydrolytic enzyme system synthesized by Trichoderma konningen is not perfect enough to fully hydrolyze the notoginseng slag, thus limiting the enzymatic conversion of the notoginseng slag to obtain sugar rate, which is not conducive to the growth of bacteria; 3. mold cells The protein content of the fermented product is limited, thereby limiting the improvement of the protein content in the fermented product; 4, the palatability of the fermented product is relatively poor

Embodiment 1

[0032] Example 1 In this example, notoginseng slag was used as raw material, and Aspergillus niger (Aspergillus niger 3.6187) / Saccharomyces cerevisiae (Saccharomyces cerevisiae 2.1042) were used as strains to carry out mixed-bacteria solid-state fermentation to produce health-care feed. Specific steps are as follows:

[0033] 1. Pretreatment of notoginseng slag

[0034] Firstly, the notoginseng dregs are dried in an oven at normal pressure and 60° C., and the time is limited when the notoginseng dregs are in an easily crushed state. The dried notoginseng slag is crushed and sieved, and the notoginseng slag with a particle size of 0.2-0.4 mm is selected for subsequent processes.

[0035] 2. Ingredients and mixing

[0036] First add 4g of ammonium sulfate to 150g of water, mix evenly, and then mix the solution with 100g of pretreated notoginseng slag powder evenly.

[0037] 3. Sterilization

[0038] The mixture is sterilized by high-pressure steam sterilization: steam pressu...

Embodiment 2

[0044] Example 2 In this example, notoginseng slag was used as raw material, and Aspergillus niger (Aspergillus niger 3.6187) / Candida tropicalis (Candida tropicalis 2.587) were used as strains to carry out mixed-bacteria solid-state fermentation to produce health-care feed. Specific steps are as follows:

[0045] 1. Pretreatment of notoginseng slag

[0046] Firstly, the notoginseng dregs are dried in an oven at normal pressure and 60° C., and the time is limited when the notoginseng dregs are in an easily crushed state. The dried notoginseng slag is crushed and sieved, and the notoginseng slag with a particle size of 0.2-0.4 mm is selected for subsequent processes.

Embodiment 3

[0056] Example 3 In this example, notoginseng slag was used as raw material, and Aspergillus niger 3.6187 / Aspergillus oryzae 3.761 / Candida utilis 2.281 were used as strains to carry out mixed-bacteria solid-state fermentation to produce protein feed . Specific steps are as follows:

[0057] 1. Pretreatment of notoginseng slag

[0058] Firstly, the notoginseng dregs are dried in an oven at normal pressure and 60° C., and the time is limited when the notoginseng dregs are in an easily crushed state. The dried notoginseng slag is crushed and sieved, and the notoginseng slag with a particle size of 0.1-0.5 mm is selected for subsequent processes.

Abstract

The invention discloses a method for producing health feed by using notoginseng residues fermenting. The method comprises: (1) pretreating notoginseng residues through drying, crushing and screening; (2) uniform mixing the pretreated notoginseng residues, water and nitrogen source; (3) treating the mixed materials through steam sterilization; (4) inoculating moulds and yeasts on the sterilized materials to carry out mixed culture solid-state fermentation; (5) drying the fermented products to obtain the health feed. According to the method provided by the present invention, the notoginseng residues can be transformed into a protein feed with disease prevention and health function. With the method provided by the present invention, the notoginseng residues are used as resources, a purpose of changing waste into valuables is realized, such that environmental pollution is reduced, and greenness health feed without antibiotics is provided for breeding industry.

Description

technical field [0001] The invention belongs to the field of industrial waste recycling, and relates to a method for producing health-care feed by solid-state fermentation of notoginseng slag. Background technique [0002] The use of food industry waste, agricultural and sideline product leftovers, crop straw and other waste biomass resources to ferment and produce single-cell protein is a hot spot in current research and development. The solid-state fermentation method has the characteristics of simple process, low energy consumption, low equipment investment and high yield, and is favored by many researchers and producers in the field of biomass conversion. [0003] Panax notoginseng is a plant of the genus ginseng of Araliaceae, which is a traditional Chinese medicinal material in my country. As a medicinal and edible plant, Panax notoginseng has been believed to have the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain ...
