Effects of tilapia bone gelatin addition in broccoli jelly candy towards the protein, fat, fiber, and vitamin C content

This study aims to evaluate the effect of tilapia bone gelatin addition to the formulation of broccoli jelly candy and determine the best formulation from its protein, fat, fiber, and vitamin C content. The results show that tilapia bone gelatin addition to broccoli jelly candy significantly increases protein content from 8.17 - 12.19%, due to the gelatin composition that mostly consists of protein. This addition also increases the vitamin C content from 7.26 - 15.18 mg/g, due to gelatin's ability to improve the thermal stability of ascorbic acid. However, the addition of gelatin does not affect the fat and fiber content. The best formulation based on protein content is Formulation 6 (13g of gelatin), meanwhile, formulation 4 (11g of gelatin) has the best formulation for vitamin C content.
