Abstract

Deep fat frying is a popular frying method in the world. There are several chemical reactions that occur during the frying process, namely oxidation, hydrolysis and polymerization. These reactions will influence to the physicochemical properties of the oil, such as increasing-decreasing in the peroxide value, an increasing in free fatty acids, a decreasing in the iodine value, an increasing in viscosity and a decrease in the smoke point. The types of oil will affect to the stability of physicochemical properties. Oils rich in unsaturated fatty acids tend to have low heating stability. The type of fried food will also affect the stability of the oil used. Animal-based food (chicken, chicken nuggets and cod) tend to cause oil deterioration more quickly than plant-based foods (potato and banana).

Abstract

Gelatin is one of the popular ingredients and additives in food industries. They have been applied in various roles, including stabilizers, thickeners, and emulsifiers. Bovine (cattle or cow) is one of the most widely used a source of gelatin. Unfortunately, they are still limited in particular considerations. For example, bovine gelatin is unacceptable in some Hindu communities. And the risks of Bovine Spongiform Encephalopathy (BSE) contamination, spreading, and outbreak related to bovine as a source. To challenge these limitations, poultry is another promising source. Current studies have found a similarity between poultry or chicken-based gelatin and bovine gelatin. However, investigation on the comparability of their gel strength is still rare.  It is generally accepted that gel strength is the most essential characteristic of gelatin.  This systematic review examined the gel strength between poultry gelatin and bovine gelatin. There were 795 papers screened, 29 full-text papers assessed, and 10 papers reviewed. The meta-analysis shows that chicken feet (CFG) and head (CHG) gelatin possessed a higher gel strength value than bovine gelatin. In contrast, the gel strength of chicken skin gelatin (CSG) and bovine gelatin did not differ significantly. The meta-analysis demonstrates that the gel strength of duck feet (DFG) and skin (DSG) gelatin is comparable with bovine gelatin. Thus, this study exposed the feasibility of CSG, DFG, and DSG, which can be the substitute for bovine gelatin.
