Fruit and vegetable residue

Blueberry pomace (dietary fiber

and ethanolic extract)

Improved UV barrier properties, provided

antioxidant properties to the gelatin-based

film against sunflower oil oxidation

[16]

Blueberry pomace and red grape

skin

Provided active atmosphere to the chitosan

and carboxymethylcellulose films,

increased oxygen permeability property

[12]

Banana peel flour

Low tensile strength, good barrier

properties depending on the starch content

[23]

Potato peel and sweet lime

pomace

Improved mechanical and barrier

properties

[19]

Sweet potato starch and lemon

waste pectin

Incorporation with TiO2 increased the

tensile strength and elongation provided;

UV protection capacity

[11]

Selecta orange, passion fruit,

watermelon, lettuce, courgetti,

carrot, spinach, mint, taro,

cucumber, and rocket and potato

peel

Provided the high solubility film, addition

of potato film residue improved the tensile

strength with accepted color values

[6]

Grain waste

Defatted mustard meal

Antimicrobial properties against

L. monocytogenes

[22]

Soybean residue

Addition of citric acid improved the

mechanical and barrier properties and

hydroscopic surfaces

[24]

Isolated hazelnut meal (protein)

The film provided with bioactive nature,

lightest colored with the good gelation

properties of proteins

[14]

Rapeseed protein

Film showed antioxidation effect against its

oil oxidation

[25]

Rice flour

The water vapor permeability showed two

times greater than the starch-based film.

Film with glycerol showed bad water

barrier property and with sorbitol showed

good water resistance

[26]

Film/Coating Materials from Marine Biowaste

In a global marine food production of 79.3 million tons, the sea food industry waste is

estimated to be 39.6 million tons. The wastes from the marine food processing indus-

tries mainly include bones, skin, cut offs, shell, viscera, and heads which are utilized

as a fertilizer or dumped in to sea causing serious environmental impacts. Fish waste
