Problems solved by technology

Sodium diacetate is a new type of antifungal agent that has been introduced to the market in recent years. Although it overcomes the above-mentioned shortcomings of propionic acid, its addition is relatively large. Each ton of feed requires 3000-5000 grams of sodium diacetate, and the use cost is high. And when too much is added, the palatability of the feed is not good
[0003] Dimethyl fumarate and monomethyl fumarate are banned antifungal agents, but because their antifungal effect is 2-6 times that of propionic acid and its salts, more than ten times that of sodium diacetate, and the price is cheap, Often used secretly by some companies, but they are strongly sensitizing to the skin

Embodiment 1

[0011] Take 1 gram of chitosan oligosaccharide with a molecular mass of 3000 Daltons, pre-mix it with 25 kilograms of corn flour, stir it in a mixer for 20 minutes, put it into the feed production line to produce 1 ton of feed after mixing evenly, and keep the produced feed sealed. .

[0012] In the above-mentioned embodiment, 10 parts were randomly sampled at different points of the feed, each sample was 100 grams, sealed in a sample bag, placed in a MHP-160 mold constant temperature and humidity incubator, and the temperature was set at 35 + 1 ℃, humidity 80%-82%, observe the moldy situation; and at the same time take 5 parallel blank samples and put them in the same incubator for observation. The results showed that the five parallel blank samples in the incubator had mildew within 40-48 hours respectively, while the feed added with anti-fungal agent had no sign of mildew after 30 days of observation.

Embodiment 2

[0014] Take 10 grams of chitosan oligosaccharides with a molecular weight of 3000 Daltons, pre-mix them with 25 kilograms of corn flour, stir in a mixer for 20 minutes, and put them into a feed production line to produce 1 ton of feed after mixing evenly. The produced feed is sealed and stored .

[0015] In the above-mentioned embodiment, 10 parts were randomly sampled at different points of the feed, each sample was 100 grams, sealed in a sample bag, placed in a MHP-160 mold constant temperature and humidity incubator, and the temperature was set at 35 + 1 ℃, humidity 80%-82%, observe the moldy situation; and at the same time take 5 parallel blank samples and put them in the same incubator for observation. The results showed that the 5 parallel blank samples in the incubator began to go moldy within 40-48 hours respectively, while the feed added with the anti-fungal agent had no signs of mildew after 45 days of observation.

Embodiment 3

[0017] Get 100 grams of chitosan oligosaccharides with a molecular weight of 3000 Daltons, pre-mix them with 25 kilograms of corn flour, stir them in a mixer for 20 minutes, and put them into a feed production line to produce 1 ton of feed after mixing evenly. The produced feed is sealed and stored .

[0018] In the above-mentioned embodiment, 10 parts were randomly sampled at different points of the feed, each sample was 100 grams, sealed in a sample bag, placed in a MHP-160 mold constant temperature and humidity incubator, and the temperature was set at 35 + 1 ℃, humidity 80%-82%, observe the moldy situation; and at the same time take 5 parallel blank samples and put them in the same incubator for observation. The results showed that the 5 parallel blank samples in the incubator began to go moldy within 40-48 hours respectively, while the feed added with the anti-fungal agent had no signs of mildew after 60 days of observation.

Abstract

The invention discloses a feed mildew resisting method. During the feed production process, a chitosan oligosaccharide mildew resistant agent is pre-mixed with grinded corn flour and other edible powder, then the mixture is stirred and mixed in a stirrer, then the mixture is added into the feed, and finally the finished feed is sealed and preserved; wherein the mass percentage content of the added chitosan oligosaccharide mildew resistant agent is 1 to 1000 ppm. The feed mildew resisting method can effectively prevent feed mildew, contains little additive, has a low cost, and can be applied to every animal feed.

Description

technical field [0001] The invention relates to a mildew-proof method for feed, which can keep fresh and prevent mildew when the amount of anti-mold agent added is very small. Background technique [0002] my country's feed production has reached about 150 million tons. Feeds are prone to mildew during storage, and the amount of anti-fungal agents is very large. Currently, the main anti-fungal agents allowed to use are propionic acid and its salts, sodium diacetate, etc. Propionic acid and its salts account for about 70% of the total amount of antifungal agents in the market. The self-production of propionic acid in my country is very low. Internationally, the production of propionic acid is mainly monopolized by companies such as BASF, and the price has always remained high. Propionic acid is highly volatile, highly irritating, and corrosive to equipment. Sodium diacetate is a new type of antifungal agent that has been introduced to the market in recent years. Although it o...
