Summary
Glucose liquid is a carbohydrate ingredient derived from plant sources, typically corn or wheat, and is presented as a clear, viscous syrup. Its primary purpose in pet food is to provide a readily available source of energy and to enhance palatability. Rather than occurring in its natural crystalline form, glucose is utilised in a liquid state to ensure ease of mixing and consistent absorption.
Why it's used?
Glucose liquid is included as a cost-effective carbohydrate source that provides readily available energy and enhances palatability. It may also function as a humectant, helping to maintain product moisture and texture stability.

Summary
Hydrolysed vegetable protein is a plant-derived ingredient produced by breaking down vegetable proteins into smaller peptides and amino acids through hydrolysis. Its primary purpose is to enhance palatability and provide a readily digestible source of protein. Rather than being used in its original whole food form, it is utilised in a hydrolysed state to optimise digestibility and reduce allergenic potential.
Why it's used?
Hydrolysed vegetable protein is included as a cost-effective source of amino acids and to enhance palatability through the creation of savoury flavours. It also allows manufacturers to optimise protein content while maintaining a desirable product texture and appearance.

Summary
Hypromellose is a semi-synthetic, plant-derived compound created from cellulose, a natural polymer found in plant cell walls. It is primarily used in pet food as a binder, thickener, or coating agent to improve texture and stability. Hypromellose is not used in its raw plant form; instead, it is processed and modified to achieve the desired functional properties for safe and effective use in formulations.
Why it's used?
Hypromellose is included as a processing aid and coating agent to improve the stability and shelf life of certain nutrients or medications within pet food formulations. It also helps control the release of active ingredients in specialised diets or supplements.

Magnesium stearate is a compound derived from the mineral magnesium and stearic acid, a fatty acid typically sourced from plant or animal origins. It is primarily used as a flow agent in pet food manufacturing, ensuring even mixing and preventing clumping. Magnesium stearate is not used in its natural metallic form; instead, it is utilised as a safe, bioavailable compound to optimise processing.
Why it's used?
Magnesium stearate is included as a flow agent to prevent ingredients from clumping and to optimise the manufacturing process by ensuring consistent mixing and tablet formation. Its use supports production efficiency and product uniformity rather than providing direct nutritional benefits.
