Description

Technical Field

[0001] This invention relates to a method for preparing green biological feed from the residue of banana taro polyphenol flavonoid extraction, belonging to the field of agricultural waste resource utilization technology. Background Technology

[0002] Canna edulis Ker, also known as banana taro, is a perennial herbaceous plant belonging to the genus Canna in the family Cannaceae. It is widely cultivated in southwestern and southern my country and is a high-yield starch crop. However, the starch processing of Canna edulis produces a large amount of starch residue. Its stems, leaves, and fine roots are often discarded or used as low-grade animal feed, resulting in resource waste and potential environmental pollution.

[0003] The residue from the extraction of polyphenols and flavonoids from banana trees still contains a small amount of active substances and nutrients such as cellulose and crude protein, showing potential for feed use. However, current processing methods do not involve deep processing, resulting in poor palatability and low nutrient utilization, making it difficult to realize its value. Traditional biological feed preparation processes also have many drawbacks, failing to achieve efficient and green conversion of such residues.

[0004] Based on this, we developed a simple, environmentally friendly, and efficient method for converting the residue from the extraction of banana taro polyphenol flavonoids into green biological feed. This method can solve the problem of residue pollution, broaden feed sources, and reduce breeding costs, and has important practical application value. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the existing technology and provide a method for preparing green biological feed from the extract residue of banana taro polyphenol flavonoids, which can not only solve the problem of residue pollution, but also broaden the feed source and reduce the breeding cost.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A method for preparing green biological feed from the residue of banana taro polyphenol flavonoid extraction includes the following steps: S1: Waste residue pretreatment: Extract the wet waste residue of banana taro polyphenol flavonoids, dry it at 50-60℃ to a moisture content of 10%-15%, and pulverize it through a 40-60 mesh sieve to obtain raw material powder; S2: Ingredient Mixing: Take 70-80 parts raw material powder, 10-15 parts wheat bran, 5-10 parts corn flour, 3-8 parts soybean meal, 1-2 parts brown sugar, and 0.5-1 parts compound inorganic salt by weight, mix evenly, adjust the moisture to 55%-65%, and make fermentation base material; S3: Activation of bacterial strains: A compound bacterial agent containing Bacillus subtilis, Lactobacillus plantarum, and Candida utilis at a live count ratio of 3:2:1 is activated in warm water at 35-40℃ for 20-30 minutes to obtain an activated bacterial solution; S4: Anaerobic fermentation: Add activated bacterial solution at 0.3%-0.6% of the fermentation substrate mass, and perform anaerobic fermentation at a constant temperature of 28-35℃ for 5-7 days; S5: Post-processing: Dry at 40-50℃ until moisture content ≤12%, pulverize and sieve to obtain green biological feed.

[0007] Furthermore, in step S2, the composite inorganic salt is composed of ferrous sulfate, zinc sulfate, and calcium dihydrogen phosphate mixed in a mass ratio of 1:1:2.

[0008] Furthermore, during the anaerobic fermentation process in step S4, the mixture is turned over every 24 hours to ensure uniform fermentation.

[0009] Furthermore, the total viable count of the compound fermentation agent is ≥10. 9 CFU / g.

[0010] Furthermore, the resulting product has a crude protein content of ≥20% and a crude fiber content of ≤13%, meeting the standards for green biological feed. Compared with the prior art, the beneficial effects of the present invention are:

[0011] Firstly, it realizes the resource utilization of banana taro polyphenol flavonoid extraction residue, completely solving the resource waste and environmental pollution problems caused by direct disposal or accumulation of residue, which is in line with the concept of circular agriculture development. Secondly, it overcomes the shortcomings of existing treatment methods, such as poor palatability and low nutrient utilization rate, and improves the feed value of extraction residue through scientific transformation, giving full play to the role of its residual active substances and nutrients. Thirdly, the process is simple, green and environmentally friendly, and low in cost, avoiding many drawbacks of traditional biological feed preparation processes, achieving efficient transformation of extraction residue, while broadening the sources of feed raw materials and reducing breeding costs, and has significant practical value and promotion prospects.
