Benefits of banana peel and their applications.

Nutrient Content	Extraction Method	Properties of Extracted Component	Application	Purpose	References
Protein	Acid extraction (glacial acetic acid)	With antioxidant and anti-fungal properties	Food or feed	Increase the content of amino acids in food or feed	[69]
Dietary fiber	Prior to extracting the dietary fiber, tap Water was used to rinse the wet milled BP powder.	- High dietary fiber content with a 4:1 IDF/SDF ratio - High oil and water holding capacities	Chicken sausage, fish patties, cookies	To increase the amount of dietary fiber	[89,91,92,93]
Fatty acids	ND	Anti-atherosclerotic, anti-thrombotic	Drugs that prevent cardiovascular disease, cancer, osteoporosis, diabetes, and other illnesses	Increasing the content of fatty acids in food	[71,72]
Mineral	ND	- High calcium, phosphorus and potassium content - Helps maintain blood pressure and Manage heart and breathing difficulties	Used as fertilizer to supplement soil nutrients	Improve soil fertility	[94]
Pectinases	BP powder was added to a base medium that already contained yeast extract, K₂HPO₄, KH₂PO₄, and KNO₃, following that, the samples were incubated in a solution at 37 °C while being shaken at 150 rpm.	The four lactic acid bacteria that were studied responded positively to the prebiotic effects of the banana peel powder that this enzyme hydrolyzed, suggesting that B. amyloliquefaciens TKU050 pectinase may be a good option for generating prebiotics	Release fibers by attacking non-cellulosic components in the sheath	get cellulose	[95]
Carbohydrate (pectin, xylose, xylooligosaccharides)	Banana peels were pre-treated with citric acid and alkaline solutions, then enzymatic hydrolysis (Cellic^® CTec2) was performed on the peels	The breakdown of a banana peel demonstrated that pectin, xylose, and xylooligosaccharides all necessary carbohydrates could be removed from its cell walls with a high yield	Replenishes the role of carbohydrates in the body, but also has the effect of protecting the liver and detoxification	Using Banana Peels as a Carbohydrate Supplement	[96]
Polyphenols	ND	Significantly reduces the peroxide value of fish balls	Fish ball preservative	Preservation freshness to increase the storage time of fish	[78]
