Gelatin?based films incorporated with Arbutus unedo fruit extract (AFE) were prepared and characterized. LC?DAD analysis demonstrated that the most abundant phenolic compounds in AFE procyanidin B2 gallic acid. The incorporation of gelatin tested film (TF) caused a remarkable decrease water vapor permeability (5.01 × 10–? g.mm/h.cm².Pa) compared to control (CF). FTIR analyses presented broadeni...

Collagen is the main structural protein of the different connective tissues, such as skin, bone, cartilage and tendons, and comprises about one-third of total proteins in mammals. Collagen extracted from collagen-rich materials with hot water is known as gelatin. The common materials used for extracting gelatin include pig skin (46%), bovine hide (29.4%), bones (23.1%) and other sources (1.5%) ...
