Description

Glue-free pet canned food and preparation method thereof

Technical Field

The invention relates to the field of pet food preparation, in particular to a glue-free pet canned food and a preparation method thereof.

Background

The pet can is different from pet food in the conventional sense and is an important staple food source for pet dogs and cats. The tin can product meets the nutritional requirements of pet cats and simultaneously needs to maintain the color, tenderness and morphological integrity of the pet cans. Different from pet snack cans, the cans are daily rations which can meet the complete and balanced nutrition of pet dogs and cats and replace puffed staple food. Generally, the animal source is a gelatinous solid with a water content of 75-80%, wherein the animal source can be more than 90%. The problems of unstable form, easy breakage and the like are caused by the phenomenon of water overflow in the processing process of high temperature and high pressure of fresh meat. Therefore, the gel which can keep uniform and stable shape after the canned product is filled is processed at high temperature and high pressure, which is one of the problems to be solved by the industry.

At present, edible glue is added as an additive to keep uniform and stable colloid when the pet can is opened and eaten in the industry. Such edible gums include xanthan gum, carrageenan, guar gum, locust bean gum, agar, gelatin, and the like. The edible gum is capable of maintaining the integrity of the canned food and the form stability during transportation and storage.

However, a number of literature studies have shown that certain gums can cause inflammatory reactions in the pet's gut, causing stress in pets, dogs and cats. In addition, the edible gum can absorb the nutrient substances in the intestines of dogs and cats, reduce the digestibility of the nutrient substances and improve the excretion amount. The stomach and intestine burden of the pet dogs and cats is increased, and the problems of malnutrition and dyspepsia can be caused to the pet dogs and cats.

With the gradual importance of consumers on the health of dogs and cats, the dog and cat staple food can added with the edible gum is covered by a low-end label.

Therefore, there is a need to find a gel-type canned food which can maintain a stable form without adding the above-mentioned edible gum.

The pet food in the can obtained by the step is in a jelly-like shape which is stable in shape and not easy to break.

After the glue-free pet canned food is obtained, the preparation method further comprises the step of inspecting the quality of the canned food by Sc, wherein the step of inspecting the quality of the canned food is as follows:

if yes, rejecting.

And warehousing and storing the qualified glue-free pet canned food after inspection.

The raw materials with different proportions are prepared into the glue-free pet canned food with chicken flavor by the preparation method, and the glue-free pet canned food in the embodiment is comprehensively evaluated by performing morphological stability evaluation, nutrition analysis, pet cat nutrition and health verification and pet cat palatability verification. Table 1 shows the raw material ratio of 7 kinds of non-glue canned pet foods.

TABLE 1 raw material ratio of glue-free pet canned food

100 cans stored for 30 days are randomly selected from the qualified canned foods, the shape of the gel-like foods in the cans is basically kept as before, the cans are in a stable gel-like state, and no water seeps out after the cans are stored for 30 days, so that the water locking function of the pet foods is strong, and the effects of tender meat and good mouthfeel are brought.

Furthermore, after 100 qualified canned foods are randomly selected and transported for 100Km, the internal form of the canned foods is not changed and is basically in an unbroken gel state, and the canned foods can withstand the bumping and shaking of strokes and are reliable in form. The above qualified products were subjected to pet can stability tests, and the test results are shown in table 2 below.

TABLE 2 stability test results of canned pets

As can be seen from table 2 above, the non-gelled pet canned food prepared by the preparation method in this example has a stable gel state, which is represented by: the soup is not easy to separate out, the shape of the contents is complete after storage and transportation, and collapse, rupture or deformation are avoided.

Further, 100 qualified canned pet foods without gum were randomly selected and subjected to nutritional analysis, and the results are shown in table 3 below:

TABLE 3 nutritional ingredient list of non-gelatin canned pet food

As can be seen from table 3, the pet food prepared by the method of this example has a high protein content exceeding 60% and contains a suitable amount of fat, abundant minerals and vitamins to satisfy the AAFCO full-value and balanced nutritional requirements.

Verification of nutritional efficacy

And (4) carrying out the nutrition and health verification on the glue-free pet canned food for the pet cats. Adult, healthy Linqing lion cats were selected with 20 body condition scores BCS > 3. And (5) respectively half male and half female, and feeding in a single basin. 50g of formula staple food grain can and 50g of commercial puffed staple food grain are given each day. And a test period of 30d, wherein the ingestion state, the excrement score and the mental state of the pet are carefully observed in the test period. After 30 days, all the cats were subjected to clinical observation and blood was collected for routine blood analysis and physiological and biochemical serum analysis, and the results are shown in tables 4 and 5 below.

TABLE 4 test Cat serum indices

TABLE 5 Liqing lion cat blood physiological and biochemical indexes

Experimental studies show that diseases, diarrhea and other sub-health conditions do not occur in the whole breeding period when the glue-free canned pet food 30d in the embodiment is fed. All serological indexes of the Linqing lion cats (test cats) are within a normal range. Therefore, the gel-free canned pet food with stable form is prepared by optimizing the component proportion and the preparation process on the premise of avoiding adding the edible gum, the safety of the pet food can be effectively improved, and the health hidden trouble of the edible gum on the pet can be avoided.

And (3) verifying the palatability of the pet cat:

and (4) carrying out pet cat palatability verification on the glue-free pet canned food. Adult, healthy, domestic pet cats were selected for palatability studies with body condition scores BCS > 3. Half of each male and half of the female, 10 domestic cats without digestive system diseases were tested by the double basin method. The gel-free pet canned food (a) in this example and the gel-containing staple food cat canned food (B) in the market were given 70g at 8 am, respectively, and the number of first bite visits of each cat was recorded. After 1 hour the palatability test was finished and A, B residual diets of the two products were weighed out separately. And calculating the feed intake rate. The feed intake rate is (50 g-residual material amount g)/50g, and the test lasts for 4 days. The data obtained were analyzed for SPSS variance with P <0.05 as an indicator of significant difference.

TABLE 6 palatability test results

As can be seen from the above table, the average feed intake rate of the canned glue-free pet food (a) was found to be significantly higher than the main grain canned food for competitive products (P <0.05) in the palatability study for four days. The average feed intake rate of the first visit number non-gelled pet canned food (a) is significantly higher than the competitive staple food canned food. Therefore, the non-glue canned pet food prepared by the embodiment has better palatability.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present invention, that is, any multiple embodiments may be combined to meet the requirements of different scenarios, which are within the protection scope of the present application and are not described herein again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
