Name of the ingredient
Hydrolysed Chicken Cartilage Extract (approved ABN)
Definition of the ingredient
Hydrolysed chicken cartilage extract is derived from chicken (Gallus gallus) sternum cartilage. The fresh sternum cartilage is cut from the chicken carcass and then subjected to enzymatic hydrolysis using food grade proteases. The hydrolysate is then sterilised, filtered and spray dried.
