As the core category of wet food, pet canned food's diverse textures such as mousse, meat chunks, and puree are not only key features that attract pets to eat, but also the result of the synergistic effect of raw material characteristics, processing technology, and ingredient regulation.
Related studies have shown that the texture characteristics of canned pet food are one of the core factors affecting its palatability, and precise control of texture relies on a deep understanding of the changes in raw materials and process regulation during the processing.
01 Mousse texture+pet canned food
Mousse texture cans are characterized by delicacy, uniformity and soft glutinous. The core of their formation is the full emulsification of protein and the dense construction of gel network *. At the same time, process control is required to avoid excessive fracture and agglomeration of meat fiber.
From the perspective of raw material processing, mousse cans usually use finely divided low-fat meat raw materials to remove impurities such as fascia and connective tissue to make delicate meat paste, which lays the foundation for subsequent emulsification and gel formation.
At the level of processing technology, high-speed cutting and emulsification is a key step. By using a vacuum cutting machine and maintaining a suitable vacuum degree, the proteins in the minced meat can be fully dissolved and functional proteins such as actin and myosin can be released. These protein molecules unfold under shear force, forming a molecular film with emulsifying ability, which evenly wraps the fat globules and water, avoiding the occurrence of layering. In addition, the synergistic effect of homogenization treatment is indispensable. Under appropriate pressure and temperature, homogenization treatment can further refine the meat mince particles, making the system more uniform and stable.
Ingredient regulation plays an important supporting role in the stable formation of mousse texture. In actual production, suitable colloidal components can be selected according to the formula requirements to assist in texture shaping. Some mousse cans add low viscosity konjac flour+(viscosity<100cp), which is essentially a soluble dietary fiber. Its hydrophilic characteristics can absorb a lot of water, interweave with the protein gel network, and further compact the structure.
The heating and sterilization process is a key step in the final shaping of mousse. High temperature and high pressure sterilization can not only achieve commercial sterility, but also promote protein thermal denaturation, further solidify the emulsion system, and form a uniform and delicate mousse morphology.
02 Meat texture+canned pet food
The core characteristics of canned meat with meat texture are to maintain the original fiber shape of the meat, with a certain degree of chewiness and elasticity. Its formation principle focuses on the protection of the meat fiber structure and moderate denaturation during thermal processing to avoid excessive crushing.
In terms of raw material selection, meat with intact muscle tissue and moderate fascia content is usually chosen. The freshness of the raw materials directly affects the final shape and taste of the meat pieces. The muscle fibers in fresh raw materials have good integrity and can better resist the mechanical and thermal effects during processing.
The core of processing technology lies in "reducing processing and preserving structure". For example, the processed whole or block shaped raw meat is directly canned and undergoes only one heating and sterilization treatment, which can largely preserve the original compact form of meat fibers and present a clear meat block structure in the finished product.
In addition, the construction of the soup system plays an auxiliary role in the presentation of the meat texture. By adding proper amounts of collagen, gelatin and other ingredients, the soup can form a slight gel state, which can not only fix the position of the meat, but also provide a wet environment for the meat, avoiding the drying and hardening of the meat due to excessive evaporation of water.
Meat puree texture+canned pet food
Meat puree texture canned food is between mousse and meat chunks, characterized by delicacy but retaining a small amount of fine meat fibers. Its formation principle is the moderate crushing and limited emulsification of meat fibers, balancing the delicacy and fiber sensation of the taste.
In the raw material processing stage, meat needs to be moderately crushed to remove coarse fascia and make larger particle size minced meat, while retaining some small muscle fibers, which is different from the fine minced meat in canned mousse.
In terms of processing technology, the cutting speed and time need to be precisely controlled, usually lower than the processing parameters of mousse cans, to avoid excessive crushing of meat fibers. At the same time, gentle stirring is used to preliminarily mix the minced meat with water and auxiliary materials, forming a uniform paste system.
In terms of ingredient regulation, canned meat paste has a lower dependence on colloids than canned mousse. Adding a small amount of thickening agents such as xanthan gum and guar gum+can achieve system stability. These colloids increase the viscosity of the system by adsorbing water, prevent delamination, and do not affect the presence of meat fibers.
During the hot processing, moderate heating temperature can cause moderate denaturation of meat fibers, ensuring that the meat is soft and easy to digest without completely damaging the fiber structure. In addition, the regulation of moisture content is crucial for the formation of meat paste texture. A higher moisture content can enhance the delicacy of the product, while moderate moisture control can avoid the product being too thin and ensure that the meat paste has good formability.
