Fruit protective coating

The features of instances of such potential reversals have been described and include tin coatings on steel in various foodstuffs, particularly acid fruits , cadmium coatings on steel in hard waters , and zinc and aluminium for cathodic protection of steel in natural ground-waters . 

While other organic esters are commercially available, namely cellulose butyrate and cellulose propionate, by far the most widely used is cellulose acetate, which is available as plastics, in films, sheets, fibers, and lacquers. Cellulose acetate is used in the manufacture of display packaging and as extruded film for decorative signs, and to coat a variety of fibers. Injected molded products include toothbrush handles, combs, and brushes. It is also used in lacquers and protective coatings for metal, glass, and paper. Cellulose acetate films are used in reverse osmosis to purify blood, fruit juices, and brackish water. Some eyeglass frames are...

Morpholine is a synthetic organic liquid used mainly as an intermediate in the production of rubber chemicals and optical brighteners, as a corrosion inhibitor in steam condensate systems, as an ingredient in waxes and polishes and as a component of protective coatings on fresh fruits and vegetables. Occupational exposure may occur during the production of morpholine and in its various uses, but data on exposure levels are sparse. It has been detected in samples of foodstuffs and beverages (lARC, 1989).

Waxes are mixtures of esters of long-chain carboxylic acids with long-chain alcohols. The carboxylic acid usually has an even number of carbons from 16 through 36, while the alcohol has an even number of carbons from 24 through 36. One of the major components of beeswax, for instance, is tria-conty hexadecanoate, the ester of the C30 alcohol triacontanol and the Cib acid hexadecanoic acid. The waxy protective coatings on most fruits, berries, leaves, and animal furs have similar structures. 

Methyl isobutyl ketone (MIK) is used as a solvent for vinyl, epoxy, acrylic, natural resins, nitrocellulose, paints, varnishes, lacquers, protective coatings, rare metal extraction, and dyes. In addition, it is used as a denaturant for rubbing alcohol, as a synthetic flavoring adjuvant, and as a fruit flavoring agent. 

Waxes are complex mixtures of nonpolar lipids. They are protective coatings on leaves, stems, and fruits of plants and the skin and fur of animals. Esters composed of long-chain fatty acids and long-chain alcohols are prominent constituents of most waxes. Well-known examples of waxes include camauba wax, produced by the leaves of the Brazilian wax palm, and beeswax. The predominant constituent of camauba wax is the wax ester melissyl cerotate (Figure 11.5). Triacontyl hexadecanoate is one of several important wax esters in beeswax. Waxes also contain hydrocarbons, alcohols, fatty acids, aldehydes, and sterols (steroid alcohols). 

Protective coatings, cathodic protection, and corrosion inhibitors are all potential methods for corrosion control, but they have apparently not been used to any extent in plants for processing sea water and little experience is available. These might be fruitful fields for further investigation, but it must be admitted that the economics are doubtful. 

Products and Uses As a protective coating for grapefruit, lemons, limes, oranges, tangelos, tangerines, in adhesives, and printing inks. Extends shelf life of fruits. 

Waxes are water-insoluble and not as easily hydrolyzed as fats and oils consequently, they often occur in nature as protective coatings on feathers, fur, skin, leaves, and fruits. Sebum, a secretion of the sebaceous glands of the skin, contains many different waxes. It keeps the skin soft and prevents dehydration. Waxes are used commercially to make cosmetics, candles, ointments, and protective polishes.
