Table 4. Utilization and Application of Pomegranate Peel in the Formulation of Value-Added Products.

Products Formulations Results and Findings Ref
Meat Products      
Goat meatballs Lean goat meat, PPP, clove essential oil, oregano essential oil, refined vegetable oil, condiment paste, dry spice mix, and refined wheat flour. Treated samples had considerably higher mean fat values and fiber percentages as compared to control samples. (107)
Chicken meat patties Chicken meat, sodium chloride, sodium tripolyphosphate, sodium nitrate, spice mix, condiments, breadcrumbs, water, egg liquid, fat, PPP, PPP aqueous extract, pomegranate aril baggage powder, pomegranate aril bagasse powder aqueous extract, and butylated hydroxytoluene. Compared to pomegranate aril bagasse powder treated samples, PPP had a much higher phenolic content. During refrigerated storage, the TBA value of both control as well as treated patties rose dramatically. Nonetheless, during storage, the TBA values of PPP and aril bagasse powder were considerably lower than those of the control samples. The total plate count and psychrotrophic count of treated samples increase at a slower rate than that of control samples. (108)
Refrigerated meatballs Beef, breadcrumbs, onion powder, garlic powder, black pepper, cumin, coriander, salt and water, crude PPP, and nano-PPP. The crude peel’s FRAP, total phenolic, flavonoid, scavenging activity, and reducing power increased after being ground. Crude and nano-PPP were added to the meatball, which prevented the development of volatile nitrogen, peroxide, and TBARS, thus preserving the sensory qualities for a cold storage period of 9 days. (109)
Beef burger Lean meat, fat tissues, sodium chloride, starch, garlic, onion, spice mixture, water, dried PPP. Moisture content showed a downward trend with increased PPP concentration. Post refrigeration period of 12 days, the protein level of beef burger samples having pomegranate peel concentrations of 2 and 3% was relatively higher, at 14.33 and 14.77%. The considerable difference in TBARS values of samples with 1, 2, and 3% PPP and that of the control sample revealed the beneficial effect of pomegranate peel as a natural antioxidant source. (110)
Refrigerated minced beef meat Beef, pomegranate peel ethanolic extract, butylated hydroxytoluene, oil. Samples treated with ethanolic extract of pomegranate peel experienced a considerable reduction in primary as well as secondary oxidation. Ethanolic extract of 1% concentration received the highest scores concerning organoleptic attributes (color, odor, and overall acceptability). (111)
BakeryProducts      
Muffin cakes Wheat flour, egg, sugar, corn oil, milk, PPP, and baking powder. A significant increase in the total dietary fiber upon substitution with PPP. Control recorded 2.36%, and the PPP substituted sample ranged from 2.80% to 6.48%. Compared to the control muffins, all levels of PPP muffins exhibited significantly greater total phenolic content and antioxidant activity. The drop in the crumb and crust Hunter L and b values increases with the amount of PPP added. (112)
Cakes Wheat flour, soybean flour, PPP, baking powder, sugar, butter, eggs, and vanilla essence. The crude fiber and ash content of all types of value-added cakes increased from 2.23 to 3.03% and 1.81 to 2.15%, respectively, as the proportion of PPP substituted increased. The control sample had an overall acceptability of 7.40, that is, liked moderately, whereas the cakes supplemented with wheat, soybean flour, and PPP at levels of 85:10:5, 82.5:10:7.5, and 80:10:10 received the score of 7.80, 7.74, and 7.96, respectively, falling into the “liked very much” classification. (113)
Cupcakes Wheat flour, PPP (5, 10, 15 and 20%), sugar, shortening, fresh egg, milk powder, baking powder. Cupcakes with 20% supplementation recorded the highest value of ash (1.92%). The highest value for the taste was observed in cupcakes supplemented with 5% PPP. Overall acceptability exhibited a downward trend with regard to the subsequent increase in the concentration of PPP. (114)
Biscuits Wheat flour, margarine, sugar, salt, baking powder, and PPP. The values of antioxidant activity, total phenolic content, soluble, insoluble, as well as total dietary fiber were observed as an increase in PPP. The flavor of biscuits made with 18% PPP was more acidic and bitter, which was thought to cause the fall in sensory scores. (115)
DairyProducts      
Curd Curd, PPE (dried powder), whey protein concentrate, skim milk powder. With the successive increase in PPE concentration, the overall phenolic content and antioxidant activity of curd increased. However, sensory qualities deteriorated with a further rise in PPE concentration. PPE made curd resistant to microbial count development, pH fluctuations, and whey syneresis during storage period. (116)
Fermented milk beverage Milk, standard starter culture containing Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus, functional strains, Lactobacillus plantarum, and Bifidobacterium longum subsp. longum, PPE. The antioxidant activity of the fermented milk beverage FMPO 300 (300 mg/mL) was higher than that of FMPO 150 (150 mg/mL). In-vivo research revealed that rats given a functional milk beverage for 30 days showed significantly lower levels of triacylglycerol, LDL cholesterol, and total cholesterol. Also, they had higher HDL cholesterol levels. (117)
Oil Products      
Edible oil Sunflower, soybean, and corn crude oils, PPE. Compared to the negative controls (without antioxidant) and the synthetic antioxidant TBHQ-200, in all of the test oils, the pomegranate peel methanolic extract at varying concentration levels showed better antioxidant potential. (118)
Preservatives      
Meat Products Mutton ribs, spice mixture, condiment mixture, table salt, fat, and pomegranate rind extract. Even though they were much lower across all storage intervals in the products treated with pomegranate rind extract, the free fatty acid (FFA) levels significantly rose from day 0 to day 21. Over the course of storage, the TPC of the products treated with pomegranate rind extract increased noticeably, and the values were continuously lower than the control. Pomegranate rind extract-treated products significantly outperformed controls regarding appearance and color between the 14th and 21st storage days. (119)
