Novel method of hydrolysed collagen extraction from hide trimming waste

Purba, F. and Suparno, O. and Rusli M.S. and Fatimah I. (2023) Novel method of hydrolysed collagen extraction from hide trimming waste. International Food Research Journal (Malaysia), 30. pp. 365-374. ISSN 2231 7546

Hide trimming waste is a by-product of tannery. Collagen is the main structural protein in hide trimming waste (70%), and extensively utilised in numerous industries including food, non-food, cosmetics, and medical. Research related to the development of hydrolysed collagen (h-collagen) extraction methods from cowhide, especially from the hide trimming waste, is still limited. The present work thus aimed to develop a four-step method for extracting h-collagen from hide trimming waste, and examine the product's properties. The present work successfully developed a method for extracting h-collagen from trimming waste with a 20.35% yield. Analysis of molecular weight, FTIR, and amino acid composition confirmed that the product was h-collagen with a molecular weight of 16 - 23 kDa. This h-collagen had higher antioxidant activity than commercial h-collagen, with an IC50 value of 238.5 ppm.

Abstract

Hide trimming waste is a by-product of tannery. Collagen is the main structural protein in hide trimming waste (70%), and extensively utilised in numerous industries including food, non-food, cosmetics, and medical. Research related to the development of hydrolysed collagen (h-collagen) extraction methods from cowhide, especially from the hide trimming waste, is still limited. The present work thus aimed to develop a four-step method for extracting h-collagen from hide trimming waste, and examine the product's properties. The present work successfully developed a method for extracting h-collagen from trimming waste with a 20.35% yield. Analysis of molecular weight, FTIR, and amino acid composition confirmed that the product was h-collagen with a molecular weight of 16 - 23 kDa. This h-collagen had higher antioxidant activity than commercial h-collagen, with an IC50 value of 238.5 ppm.
