Preparation method suitable for crisp cowhide pet chews for pets in different stages

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 ...

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;

[0052] The present embodiment provides a kind of preparation method of the cowhide product suitable for adult dogs, comprising the following steps:

[0053] (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;

[0054] (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;

[0055] (3) Slicing and shaping: cutting the microwave-treated cowhide into squares;

[0056] (4) Preparation of enzymolysis solution: configure 100L of propylene glycol solution with a volume fraction of 60%, add the following substances in the propylene glycol solution: 0.2 mg of subtilisin, 0.4 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;
