Enzymatic deodorants

Cosmacol Eli Moisturizer emollient and enzymatic deodorant efficient alternative of Tridosan safe inhibitor of the body odor... 

Today, dermoenzymatic deodorants can be used in microcapsules to combat this problem. In the past, many different enzymatic deodorants have been identified which act on hpase activity, preventing the generation of perspiration odor. Cos-macol Eli (Celessence), in contrast to other enzymatic deodorants, is a stable product (it is an ester derivative of lactic acid) which acts as an enzymatic deodorant by... 

The supercritical fluid extraction of oil seeds has been investigated extensively by several authors [34,98]. Possible applications of supercritical fluids in the edible-oil industry include deacidification, deodorization, and fractionation of crude oils and chemical conversion (like hydrogenation, and enzymatic reactions). 

Volatile aldehydes, including 1-hexanal, may be primarily responsible for the beany odor of soybean (10, 13, 14). They are present even in defatted soybean flour. Recently, Chiba et al. (15) have deodorized soybean flour by treatment with aldehyde dehydrogenase from bovine liver. Deodorization was a result of converting aldehydes to acids, e.g., 1-hexanal to caproic acid. They postulated that both free and bound aldehydes can act as substrates for this dehydrogenase. Consequently, enzymatic treatment resulted in a product without beany odor.

Oil seeds are dried at first to a water content of about 10% to avoid enzymatic hydrolysis. Then they are expelled (pressed) to a fat content of 20%. The ex-peller cake is extracted with hydrocarbons, usually hexane, and is later removed from the oil with water steam. Hexane solubility in water is only 0.1%. Bleaching of the raw oils occurs with aluminum silicates containing montmorillonite at approximately 60°C. Deodorization is the final step in the purification of the fatty raw materials from plants and occurs essentially by steam distillation.

Cottonseed oil also contains cyclopropenoid fatty esters that are toxic and block the enzymatic conversion of stearic to oleic add. These cyclo-propenoids are essentially inactivated by heat during deodorization (Eaves et al., 1968 White, 1992). 

The final section of the book, which examines research efforts in processing, contains review chapters in the important areas of deodorization and fat fractionation. Additionally, chapters are included on the physical effects of hydrogenation (as it applies to sunflower oil) and physical effects of blending and interesterification (both chemical and enzymatic) as they apply to a number of fat systems.
