Gelatin (Bloom 250-270)

Gelatin, derived from the Latin gelatus (‘stiff’ or ‘frozen’), is a translucent, colorless, and flavorless biopolymer obtained from the partial hydrolysis of collagenous animal tissues. It exhibits distinct physical states: brittle when dry and rubbery when hydrated. While gelatin is the precursor to hydrolyzed collagen (collagen peptides), it is critical to distinguish between the two: gelatin functions as a gelling agent due to its high molecular weight, whereas hydrolyzed collagen has been further processed via enzymatic hydrolysis to break down protein chains, thereby losing its gelling capability.

Gelatin is extensively utilized as a gelling and encapsulating agent in food, beverages, pharmaceuticals, and cosmetics. In pharmaceutical manufacturing, precise specifications are essential; for example, high-Bloom gelatin (250–270 Bloom) with a 30-mesh particle size is specifically used to meet the demanding structural requirements of capsule production.
