Problems solved by technology

[0003] At present, cowhide chewing products on the market are all processed through traditional processes such as skin washing, drying, and molding. It is difficult to apply to pets of different breeds, different growth stages and different physical conditions; and may cause damage to pet teeth, some are relatively fragile, and there is a risk of piercing the intestines and other internal organs
Therefore, in order to meet the needs of pets at different stages for chewing products, many companies are also constantly developing new products, such as the use of freeze-drying technology in order to increase the crispness of jerky, but the production cost is too high; and direct freezing of cowhide products The texture of dried products is slightly improved compared with traditional drying, but it is still hard and poor in brittleness.
There is also an acid-base swelling method to treat animal skin in order to obtain a soft texture, but it is still not crispy, and the cleaning is complicated, and the acid-base solution generated during the processing is difficult to handle, causing environmental pollution problems; there is also a separate microwave heating method. The treatment serves the purpose of puffing, but the product produced has a low degree of puffing, a hard and brittle texture, and overheating will easily cause the cowhide collagen to melt, resulting in quality deterioration and difficult to control
There are also products that use plant-based or plant-based and crushed cowhide to recombine to produce chews, but compared with animal skin chews, this type of chew has low nutritional value, poor toughness or brittleness, and weak chewing ability, which cleans the mouth. The function is poor, and it also lacks the pet's special love for natural animal skin
Therefore, it is also difficult to meet the needs of pets at different stages

Embodiment 1

[0038] The present embodiment provides a kind of preparation method of the cowhide product suitable for puppies or old dogs, comprising the following steps:

[0039] (1) Select 1000g of dried bovine split leather raw material, cut it into long strips, each 100g, soak it in clean water for 2 hours, and soak it;

[0040] (2) Microwave treatment: place the fully soaked cowhide in a vacuum microwave equipment with a vacuum degree of -80kPa, a power of 200W, a treatment time of 10min, and a product temperature not exceeding 55°C;

[0041] (3) Slicing and shaping: cutting the microwave-treated cowhide into squares;

[0042] (4) Preparation of enzymolysis solution: configure 100L of propylene glycol solution with a volume fraction of 50%, add the following substances in the propylene glycol solution: 0.6 mg of subtilisin, 0.2 mg of trypsin, 0.4 mg of calcium chloride, and 0.1 mg of lactoferrin mg, lactoperoxidase 0.05mg; stir evenly to prepare enzymatic solution;

Embodiment 3

[0065] In order to obtain cowhide chews with different product texture characteristics and sensory characteristics, the inventor also conducted orthogonal experimental screening on the enzyme dosage, enzymolysis time, and enzymolysis process in the enzymolysis process. Except for the enzymolysis process, the remaining processes and implementation The same as in Example 1, the orthogonal test factors and levels are shown in Table 4 below, the orthogonal test scheme is shown in Table 5, and the orthogonal test results are shown in Table 6;

Abstract

The invention belongs to the technical field of pet food processing, and particularly relates to a preparation method suitable for crisp cowhide pet chews for pets in different stages. The method comprises the following steps of (1) pretreatment of raw materials; (2) microwave treatment, wherein pretreated cowhide is placed in a vacuum microwave device for vacuum microwave heating treatment; (3) slicing and shaping; (4) preparation of composite enzymolysis liquid; (5) enzymolysis treatment, wherein the cut cowhide is placed in the composite enzymolysis liquid for enzymolysis treatment; and (6)drying. The cowhide is enzymolyzed based on vacuum microwave and composite enzymolysis technologies, and different functional materials permeate according to the growth need, so that cowhide pet chewseries new products with different toughness, crispness and functional characteristics are prepared.

Description

technical field [0001] The invention belongs to the technical field of pet food processing, and in particular relates to a method for preparing crispy cowhide chews suitable for pets at different stages. Background technique [0002] At present, there are several main categories of pet chews. One is made of pure cowhide or pigskin. The skin is chewy and naturally edible. But there are also some disadvantages, such as not easy to digest, pet dogs with weak stomach may cause diarrhea or vomiting after eating; in addition, the hardness is relatively large, it is difficult for young and old pets to chew, affect emotions, and it is easy to hurt teeth and oral cavity . The second category is the combination of cowhide and meat. The addition of meat greatly increases the palatability of the chew, allowing more dogs to bite and chew more actively. Chews have gradually evolved from an edible toy to a functional pet treat. These two types of chewing products occupy a considerable ...
