Abstract
Trunk bacteria reducing method in cattle and sheep slaughtering process of the present invention is related to the cattle and sheep trunk bacteria reducing method to butchering, especially batch production cattle and sheep and butchers cattle and sheep trunk bacteria reducing operating procedure in process.Including being sterilized with lactic acid liquid spray live animal fur, with 70~90 DEG C of pasteurizes of pasteurization machine trunk hot water, 85~100 DEG C of wet sterilizations carry out trunk 2.5~5.0% sterilization of lactic acid antibacterial liquid spraying lactic acid and coating problems.In slaughtering process, the present invention is greatly lowered using the surface colony sum that the method combination of four kinds of elimination trunk microorganisms can make cattle and sheep trunk final to 3.24~6.46 × 103(cfu/100cm2), and the contrast test cattle and sheep trunk surface colony sum of the prior art is up to 1.63~7.08 × 105(cfu/100cm2).The lactic acid antibacterial liquid of the present invention can keep the humble biomass level of trunk in cattle and sheep trunk table for a long time, effectively reduce microbial contamination rate, ensure beef and mutton clean and safe.
Description
Technical field
The present invention relates to the cattle and sheep trunk bacteria reducing method to butchering, especially batch production cattle and sheep butcher the ox in process
Sheep and goat carcass bacteria reducing operating procedure.
Background technology
Many studies have shown that when butchering healthy animal, musculature essence is sterile, skin, the hair of animal, Yi Jipi
Excrement, soil, dust on hair are important pollution sources, meanwhile, scale meat packing plant and preparing gradually increases, and meat is from first
Begin to be worked into away from discrete time increasing for consumption culinary art, to increase the risk of pathogenic bacteria growth.
Trunk and the Initial microorganisms that cut meat are horizontal high, can influence the shelf life of fresh meat, generate offending flavor and meat
Color;The Fresh meat of high Initial microorganisms level only has 1 day shelf life, and cold fresh meat only 3 days shelf life just will appear smelly show
As causing economic loss.
Report that 5926 people of Chinese food Poisoning Number in 2015, dead 121 people, microbes food poisoning play number
It is most with Poisoning Number;Global food in 2015 is poisoned to death 420,000 people of number, and early annual report claims poultry, red meat, meat products to be
The maximum a kind of source of European Union's sitotoxismus, the Food poisoning cases in the U.S. about 45% are caused by poultry and red meat.Comparison
Statistics indicate that Chinese animal products, which butchers processing, cuts meat microorganism level higher than about 10~20 times of USA and EU, therefore
Bacteria reducing technology is introduced in slaughtering process and standard operation, disinfectant program are imperative.
Invention content
In view of the above problems, the purpose of the present invention is carry riding out a set of to be substantially reduced the micro- life in cattle and sheep trunk surface
The bacteria reducing operating procedure method of object quantity.
The operating procedure method of the present invention is as follows:
Trunk bacteria reducing method in cattle and sheep slaughtering process, operating procedure are as follows:
(1), live animal fur sterilizes:Enter the passway of killing floor in cattle and sheep, using 0.20~0.3MPa hydraulic pressure to logical
The lactic acid liquid that mass concentration is 3~7% is sprayed on the animal hair at road junction, every sheep living sprays 70~150mL lactic acid liquid,
Every sheep living sprays 150~300mL lactic acid liquid, and spray disinfecting time waits butchering after 10~15 minutes.
A large amount of microorganisms of cattle and sheep body surface are made to be eliminated and cannot pollute and butcher rear trunk.
(2), trunk hot water pasteurize:Cattle and sheep trunk after butchering carries out ozone gas by hot pasteurization machine and adds
Thermal sterilization processing, pasteurization machine arrange parameter are:70~90 DEG C of water temperature, 6~12 seconds time kind;Then lower step trunk is carried out to steam
Vapour is sterilized.The microorganism in the superficial microbes and stomach and intestine that part is left is killed, wet sterilization small part is more heat-resisting or ensconces deep
The part microorganism killing at place.
(3), trunk wet sterilization:Cattle and sheep trunk passes through steam-pasteurized system, steam-pasteurized system setting ginseng
Number is:85~100 DEG C of vapor (steam) temperature, 6~10 seconds time kind.Kill micro- life in the superficial microbes and stomach and intestine that part is left
Object.
(4), trunk spraying lactic acid is sterilized:Use high pressure sprays fog equipment, the breast for being 2.5~5.0% by lactic acid mass concentration
Sour antibacterial liquid mist spray is on cattle and sheep trunk, and every sheep and goat carcass about sprays 50~120mL lactic acid solutions, and every ox trunk is big
About spray 100~200mL lactic acid solutions;Wherein, the lactic acid mass concentration in lactic acid antibacterial liquid is 2.5~5.0%, and lactic acid is antibacterial
Film forming agent a concentration of 3.0~5.0% in liquid, surplus is water, and lactic acid antibacterial liquid is made to ensure not trickle uniformly on trunk.It kills
Microorganism in superficial microbes and stomach and intestine that part is left, makes few microorganism long period have film and lactic acid environmentally
It is killed or irreproducible.
Preferably, in the sterilization of (4) trunk spraying lactic acid step, the film forming agent includes converted starch and chitosan, at
The mixing ratio by weight of film is converted starch 60.0~80.0%, chitosan 20.0~40.0%.Converted starch and chitosan were both
It can form a film, and be edible, pollution not generated to trunk.
Preferably, in the hot water pasteurize of (2) trunk the step of, it is 5.0 that volumetric concentration is filled in pasteurization machine
~10.0% ozone gas.Ozone gas can rapidly remove trunk surface microorganism and remove the advantageous micro- raw breeding in trunk surface
Trunk stink.
Preferably, it in (3) trunk wet sterilization the step of, generates and hydrogen peroxide is added inside the steam water of steam, steam
The volumetric concentration that hydrogen peroxide is added inside vapour water is 3.0~4.0%.The hydrogen peroxide is hydrogen peroxide liquid, and hydrogen peroxide has
Preferable quick sterilization when lower step (4) trunk spraying lactic acid, influences very little, in this (3) trunk wet sterilization to the lactic acid of spray
The step of in, with the wet sterilization for having hydrogen peroxide not only soon but also not under the influence of step operation.
Advantages of the present invention:It in slaughtering process, is applied in combination, can be made final with the method for four kinds of elimination trunk microorganisms
Cattle and sheep trunk surface colony sum drop to 3.24~6.46 × 103(cfu/100cm2), and the contrast test cattle and sheep of the prior art
Trunk surface colony sum drops to 1.63~7.08 × 105(cfu/100cm2).And the lactic acid antibacterial liquid of the present invention is in cattle and sheep trunk
Body surface can keep the humble biomass level of trunk for a long time, effectively reduce microbial contamination rate, ensure beef and mutton clean and safe.
