Pet food produced with standard techniques and compliant Pet Food Binder has excellent structural stability after soaking. It will not break, crumble or collapse during soaking for normal feeding duration. It will only soften slowly, fully meeting the soaking feeding requirements for young pets, senior pets and pets with weak gastrointestinal tracts. This is also one of the core functions of dedicated Pet Food Binder. On the contrary, pet food without binders, made with low-grade Pet Food Binder or produced with substandard techniques will quickly turn loose and mushy after soaking, impairing feeding experience and pet consumption.
Dedicated Pet Food Binder for pet food is designed with water-resistant properties. Mainstream raw materials including cross-linked starch, xanthan gum, sodium alginate and animal protein glue will not rapidly dissolve and lose efficacy upon contact with water. Instead, a hydration reaction will occur to form a high-strength and dense mesh bonding film. This film wraps all raw material particles such as meat, grains and fiber inside kibble and tightly bonds scattered ingredients into an integrated structure. In cold or warm water soaking environments, this bonding structure maintains high stability. Short-time soaking of 5 to 15 minutes for regular feeding only allows kibble to absorb water and soften for easier chewing and digestion by pets, without delamination, collapse or crumb falling off.
Pet food produced by different processes shows slight differences in soaking stability, while all can meet standards. Extruded kibble goes through high-temperature extrusion molding together with the curing effect of Pet Food Binder, so it has the most stable structure and optimal anti-collapse performance after soaking. Low-temperature baked kibble and cold-pressed kibble are molded under relatively low temperature. Supported by the bonding function of Pet Food Binder, they can also maintain complete shape after soaking and only turn soft in texture. Even when the soaking time is extended to more than 30 minutes, qualified kibble will only expand and soften as a whole instead of breaking completely. It can effectively avoid turbid liquid and sediment collapse during feeding.
The phenomenon that some pet food breaks easily after soaking does not stem from Pet Food Binder itself but results from multiple unqualified factors. First, industrial low-grade Pet Food Binder is adopted. Such raw materials have no water-resistant structure and dissolve and fail rapidly in water, unable to fix kibble. Second, the adding proportion of Pet Food Binder is insufficient. Raw material particles are loosely bonded with many gaps. Water quickly penetrates these gaps and disintegrates the internal structure. Third, defects exist in production techniques such as uneven stirring, insufficient molding pressure and incomplete drying, leading to loose kibble structure. Even with compliant Pet Food Binder, kibble will turn loose after soaking.
Besides, soaking with boiling water at extreme high temperature will slightly affect kibble integrity. Boiling water accelerates softening and decomposition of Pet Food Binder molecules. Long-time soaking in boiling water may cause minor crumb loss, while soaking with warm water for daily feeding will not be affected. To sum up, as long as compliant dedicated Pet Food Binder is selected with standard proportioning and production techniques followed, pet food maintains stable shape and resists collapse after soaking. It fully adapts to various soaking feeding scenarios and is safe and practical.
