Table 4. Agricultural Food Wastes and by-Products As Natural Food Additives for Different Types of Food Products.

functional additives food product final product quality reference
encapsulated bioactives from red pepper waste yogurt retention of carotenoid (71.43%) and polyphenols (increase up to 123.73%) and higher pigment retention during 21 days of storage time (125)
higher sensory and general acceptance due to better color, appearance, and flavor
encapsulated bioactives from grape skin whole wheat cocoa biscuits (with 1.2, 2.3, and 3.5% addition of encapsulated extract on dough weight) increase of phenolic content (up to 134%) and antioxidant capacity (up to 244%) (126)
reduction of phenolic content (16%) during cooking
change of color and not relevant positive impact on oxidative stability
encapsulated extract addition level (significant influence on the sensory acceptance)
free and encapsulated phenolic extract from olive leaf full-fat mayonnaise (∼80% oil) addition of both types of extract (improvement of dispersion degree of the sample, and causing lower spreadability, higher salty and bitter taste) (127)
addition of encapsulated extract (improvement of physical properties)
enriched mayonnaise with free or encapsulated extract (lower overall acceptance)
encapsulated black mulberry waste extract dark chocolate chitosan coated liposomal powders (better anthocyanin protection than spray-dried extract) (128)
encapsulation in liposomes (improvement of in vitro bioaccessibility of anthocyanins)
maximum fortification with encapsulated anthocyanins (76.8% based on conching temperature and pH)
onion skin powder bread enhancement of bioaccessible lipid oxidation preventers and compounds having chelating and antioxidant abilities (129)
higher antioxidant activity
2%–3% of onionskin powder addition (significant development of the antioxidant capabilities)
up to 3% of onionskin powder addition instead of wheat flour (satisfactory consumers’ acceptance)
lettuce waste flour bread reduction of dough leavening capacity, and increase of bread moisture and firmness, phenolic content (up to 3.4 g GAE kg–1), and antioxidant capacity (200%) (130)
addition of lettuce waste flour (at least 170 g kg–1) (improved fiber content (>30 g kg–1), reduction of yeast odor and flavor intensity, and increase of silage and herbaceous scent and flavor, dried fruit flavor, acid, and sour taste)
enriched bread with 170 and 575 g kg–1 addition of lettuce flour (comparable sensory properties and consumer acceptability with commercial wholemeal bread containing similar rye bran content)
olive paste flour durum wheat spaghetti the best addition amount of olive paste flour for enrichment (10% (w/w)) (131)
addition of 10% olive paste flour (an increase of total polyphenol content [from 82.39 μg/g DW to 245.08 μg/g DW], 15 times higher in apigenin, luteolin, and quercetin levels)
addition of transglutaminase (0.6%) to enriched pasta with 10% olive paste flour (increase of overall pasta quality)
enriched spaghetti with 10% olive paste flour and 0.6% transglutaminase (very similar quality with the control sample for uncooked and cooked spaghetti)
carrot pomace powder and dushab (a traditional grape juice concentrate) cakes addition of carrot pomace powder and dushab (reduction of specific volume of cakes and increase of moisture content, color difference, browning index, firmness, and reduction of cohesiveness with increase of added amount) (132)
increase of carrot pomace powder addition (increase of chewiness and gumminess)
addition of dushab (not effective on chewiness and gumminess, and decrease of cake springiness)
grape residue flour grape ice cream addition of 2% of grape residue flour (increase of protein, lipids, ash, dietary fiber, total energy value, reducing sugars, total phenolics, flavonoids, flavonols, and anthocyanins, and higher radical scavenging ability) (satisfactory sensory attributes and the best formulation among other ice creams containing grape residue flour in different levels) (133)
apple pomace powder stirred-type yogurt addition of apple pomace powder (2%–3%) (alteration on the structure of stirred yogurt) (134)
apple pomace powder addition into the diluted yogurt system (potential stabilization of acid drink and reduction of protein aggregates sedimentation)
coffee pulp extract probiotic beverage with or without kefir culture probiotic beverage from coffee pulp extract by steam pretreatment with kefir culture (improvement of phytochemicals, physicochemical properties, and enhancement of organoleptic properties, the best overall acceptance according to the control beverage without kefir cultures) (135)
