What determines whether a pet soft chew can carry the intended ingredients and shelf life?

The answer depends on ingredient loading, moisture and water activity, fat system, texture, flavour, preservative strategy, process temperature and package protection. High active loads can change taste and chew structure, while hygroscopic ingredients may affect stability. Buyers should approve a representative pilot, define physical and microbiological specifications, and confirm analytical recovery through shelf life. A soft chew is a delivery format; it does not by itself prove acceptance, efficacy or regulatory classification.
