Abstract
The invention provides a method for alleviating salmonella pollution in a pig feed, which belongs to the field of pig feeds, and aims at solving the problem that the pig feed can be easily polluted by salmonella. The invention provides a method for alleviating the salmonella pollution in the pig feed, by addition of the mixture of nitric acid and fumaric acid in the feed and transient high-temperature heating and rapid cooling, the pollution rate of salmonella in the pig feed can be reduced greatly, and other nutritional substances in the pig feed cannot be lost.
Description
Technical field
The invention belongs to pig feed field, be specifically related to a kind of method salmonella-polluted in pig feed that reduces.
Background technology
salmonellosisrefer to by all kinds salmonella caused to the mankind,
domestic animaland the multi-form general name of wild birds and beasts.The people of infection salmonella or carrier's
ight soilcontaminated food products, can make people occur
food poisoning.According to statistics in the kind of countries in the world
food posioningin, the normal row umber one of salmonellal food poisoning.China hinterland is also taking salmonella as the first.
Salmonellosis is
public healthone of significant zoonosis on, its cause of disease
salmonella enteric bacteriasection, comprises that those cause food poisoning, cause
gastroenteritis,
typhoid feverwith
paratyphoid's
bacterium.They,, except infecting people, also can infect a lot of animals and comprise
mammality,
bird,
reptiles,
fish,
amphibiousclass and
insect.After human poultry infection, can be asymptomatic carrier state, also can show as the lethal disease of clinical symptoms, it may increase the weight of morbid state or the death rate, or reduces the Breeding productivity of animal.
Along with the raising of people's living standard, also more and more higher to the requirement of food security.Pig feed is first link of " from plant to dining table " charcuterie theft-resistant link chain, if pig feed pathogen contamination easily causes mankind's food origin disease.
Summary of the invention
For addressing the above problem, the invention provides a kind of method salmonella-polluted in pig feed that reduces, adopt following technical scheme:
Reduce a method salmonella-polluted in pig feed, it is characterized in that, comprise the following steps:
(1) after adding citric acid and fumaric acid in pig feed, be uniformly mixed, obtain mixture A;
(2) by mixture A heat treatment 20-30s at 90-100 DEG C, then in 5min, be cooled to 20-25 DEG C, must reduce salmonella-polluted pig feed.
as preferably, the citric acid addition described in step (1) is the 1-1.5% of feed gross mass.
as preferably, the fumaric acid addition described in step (1) is the 0.2-0.5% of feed gross mass.
Beneficial effect of the present invention is as follows:
Salmonella-polluted method in reduction pig feed provided by the invention, by add the mixture of citric acid and fumaric acid in feed, then pass through of short duration high-temperature heating and fast cooling, can greatly reduce the pollution rate of salmonella in pig feed, and can not cause other nutriment losses in pig feed.
Detailed description of the invention
Following examples are for particular content of the present invention being described better, being not limited to protection scope of the present invention.
embodiment 1(reference examples 1)
The preparation method of pig feed: after pig feed is mixed by formula, directly granulate, obtain pig feed finished product.In formula for pig forage, do not comprise citric acid and fumaric acid, and feed is without heat treated.
embodiment 2(reference examples 2)
The preparation method of pig feed: after pig feed is mixed by formula, directly granulate, obtain pig feed finished product.Formula for pig forage comprises citric acid and fumaric acid, but without heat treated.
embodiment 3(reference examples 4)
The preparation method of pig feed: after pig feed is mixed by formula, heat treatment 20s at 90-100 DEG C, naturally cooling rear granulation, obtains pig feed finished product.In formula for pig forage, do not comprise citric acid and fumaric acid.
embodiment 4
Reduce a method salmonella-polluted in pig feed, it is characterized in that, comprise the following steps:
(1) after adding 1% citric acid and 0.5% fumaric acid in pig feed, be uniformly mixed, obtain mixture A;
(2) by mixture A heat treatment 20s at 90-100 DEG C, then in 5min, be cooled to 20-25 DEG C, must reduce salmonella-polluted pig feed.
embodiment 5
Reduce a method salmonella-polluted in pig feed, it is characterized in that, comprise the following steps:
(1) after adding 1.5% citric acid and 0.3% fumaric acid in pig feed, be uniformly mixed, obtain mixture A;
(2) by mixture A heat treatment 25s at 90-100 DEG C, then in 5min, be cooled to 20-25 DEG C, must reduce salmonella-polluted pig feed.
embodiment 6
The pig feed that embodiment 1-5 is obtained carries out salmonella detection, and the present invention adopts Tianjin Ford scholar Science and Technology Ltd. to produce
tecra salmonella detection kitdetect, testing result is as follows:
| Project | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| Salmonella-polluted rate (%) | 34 | 30 | 18 | 0 | 0 |
Claims (3)
