A kind of pets fermented dairy product and preparation method thereof
Technical field
The present invention relates to pet food and its preparing technical field, more particularly to a kind of pets fermented dairy product and its
Preparation method.
Background technology
A few days ago, with expanding economy and growth in the living standard, the quantity of people's pet feeding is increasing, to pet
The demand of food also increasingly increases, meanwhile, people treat the diet of pet and are also to have enough and eat in abandoning tradition increasingly
The idea of purpose, and then health, nutrition, fresh pet food are pursued, then occur in that functional food for pet animals.Pet function
The appearance of property food is not only a kind of fashion, it is often more important that embody the lifting of people's values.
Diet concept to the mankind is similar, and alimentary canal health accounting in functional food is declared is larger.Enteron aisle is to dote on
One of most tired organ of thing whole body, needs to do substantial amounts of work daily, digests and assimilates various foods for each organ of body and thin
Born of the same parents provide required nutrient.In addition, enteron aisle or the maximum microecosystem of pet body, the microorganism motion peace of enteral
Weighing apparatus, plays critical effect, the natural cover for defense as pet health in terms of immunity of organisms is improved.
Research shows that the probiotics such as Bifidobacterium and Bacillus acidi lactici has to improve pet functions of intestines and stomach, preventing and treating diarrhoea, reduce
The health-care efficacies such as serum cholesterol, enhancing immunity of organisms.In view of micro-ecological environment is most important to pet health in enteron aisle, increase
Plus the quantity of probiotics plays an important roll to pet health in pet body.It is beneficial in enteron aisle in the increase pet body for generally using
The method of bacterium number amount has two kinds:One is the food that directly feed contains active probiotic, and two is the non-viable bacteria food for absorbing prebiotic metaclass
Product.The pet food containing active probiotic in addition to medicine is based on Yoghourt but few exclusively for pet in the market
The probiotic acid dairy produce of making and prebiotic metaclass functional food, and field is made in pet food, either it is personal still
Professional and technical personnel, the making of pet Yoghourt all uses Hand Inoculations, easily pollution microbes and fermentation time is long, it is difficult to ensure that system
The edible safety of product, and it is difficult to industrialized batch production.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of use vacuum fermentation production prepare safety, nutrition, to doting on
Attractive pets fermented dairy product of thing and preparation method thereof.
The present invention solve the technical scheme that uses of above-mentioned technical problem for:A kind of pets fermented dairy product, by following
The raw material composition of mass percent:Fresh milk 30-70%, function major ingredient 10-30%, glucose 5-10%, APG 1-3%, breast
Sour bacteria culture fluid 1-2%, citric acid 1-5%, maltodextrin 10-20%, pet food calling material 1-2%, functional additive 0.1-0.3%;
Described function major ingredient is one or more in pachyrhizus, carrot, pumpkin.
In order to improve the cultivation effect of probiotics in the fermented dairy product, the pets fermented dairy product also includes following
The raw material of mass percent:Isomalto-oligosaccharide 2-4%, galactooligosaccharide 1-3%.
Further, after the lactic acid bacteria culture solution cultivates Bifidobacterium and Bacillus acidi lactici respectively for agar medium, put
Total total viable count of the nutrient solution being configured in the radiation sterilizing fresh milk of antibiotic-free, wherein Bifidobacterium and Bacillus acidi lactici
It is 1 × 108 -1×109 cfu·m L-1。
Further, the functional additive is in l-cn, taurine, beta carotene, aminoglucose hydrochloride
One or more.
Further, the pet food calling material is made up of the following raw material for accounting for pet food calling material mass percent:Meat and liver
Dirty mixture 60-70%, water 5-15%, trypsase 0.1-1%, lipase 0.2-0.8%, glucose 3-15%, xylose 1-5%, ferment
Female protein hydrolysate 1-5%, cysteine 1-5%, glutamic acid 2-8%, the pet food calling material is by above-mentioned raw materials through Maillard reaction system
.
A kind of preparation method of described pets fermented dairy product, comprises the following steps:
First step pretreatment of raw material:It is on the waiting list without the fresh milk of antibiotic and other raw materials and function major ingredient is cleared up and cooked;
Second step radiation sterilizing:By used raw material including lactic acid bacteria culture solution with agar medium and Work tool carry out
Radiation sterilizing, dosage 5-9kGy/ hours of irradiation, exposure time 10-40 minutes, the lactic acid bacteria culture solution for preparing did not carried out spoke
According to sterilization processing;
3rd step accesses strain:During the raw material after irradiation is accessed into fermentation tank under the protection of nitrogen or inert gas, successively divide
Jia Ru not fresh milk, the function major ingredient of pretreatment, glucose, APG, lactic acid bacteria culture solution, isomalto-oligosaccharide, oligomeric
Galactolipin;
4th step vacuum fermentation:Vavuum pump is opened, adjustment fermentation tank vacuum is 0.03-0.08MPa, in 30 DEG C -40 DEG C of temperature
Lower fermentation 12-24h, fermentation completes backlash nitrogen or inert gas to normal pressure;
5th step thickens seasoning:Maltodextrin, pet food calling material, function addition are added under the protection of nitrogen or inert gas
Agent, rotating speed is stirred 10-30 minutes under the conditions of controlling 40-50 revs/min;
6th step section pH value:Addition citric acid regulation pH value 4-5.5.
7th step is filling:Step 6 resulting material is carried out into filling and sealing, pets fermentation dairy of the invention is obtained
Product.
Compared with prior art, the advantage that possesses of the present invention is:
A kind of pets fermented dairy product that the present invention is provided contains substantial amounts of probiotics, can be adjusted after pets and doted on
The normal flora of the intestines and stomach of thing, keeps the ecological balance of microorganism, and pet body health is ensured so as to reach, and delays pet to decline
Old purpose;In addition, the pet food with yoghourt-flavored for producing by fermentation, makes it easily digest and absorb, fermentation makes
Sugar, protein in milk, fat are broken down into small molecule, improve the utilization rate of nutrition, can produce during the course of the reaction many
The vitamin and lactic acid planted can be effectively promoted pet to calcium, the absorption of phosphorus, so as to reach enhancing pet immunity of organisms
Purpose;The strict control of radiation sterilizing, vacuum fermentation and whole preparation process avoids fermentation process living contaminants, it is ensured that hair
The edible safety of ferment product, while contributing to the industrialized mass production of fermentation process;Pets fermented dairy product is added
Prebiotics component, and be conducive to Bifidobacterium and Bacillus acidi lactici to colonize and increase in enteron aisle in fusion and Yoghourt system well
Grow, and then set up normal colony balance environment, increase the adaptability that change to conditions such as food, environment of animal, reduction or
Mitigate stiff reaction, improve the comprehensive health level of body;Pets fermented dairy product adds functional additive, contributes to control
Body weight processed, improves depilation phenomenon, reduces cholesterol levels, moisten skin and reduction body odor;Meanwhile, pets fermented dairy product
Addition pet food calling material, with special aroma after merge with Yoghourt smell, have good attractant to pet, it is to avoid part
Pet is because smell reason is to the food refusal phenomenon of existing Yoghourt.
