The enzyme pectinase lowers the activation energy needed for the juice to be produced and catalyzes the reaction. Pectinases are useful in the wine industry by extracting anthocyanin from the fruit, effectively intensifying the wine coloring. [6] Pectinase can also be used to extract juices from cell walls of plants cells.
To a certain extent, all of these techniques tend to produce an extract with an aroma that differs from the aroma of the raw materials. Heat, chemical solvents, or exposure to oxygen in the extraction process may denature some aromatic compounds, either changing their odour character or rendering them odourless, and the proportion of each ...
Natural skin care uses topical creams and lotions made of ingredients available in nature. [1] Much of the recent literature reviews plant-derived ingredients, which may include herbs , roots , flowers and essential oils , [ 2 ] [ 3 ] [ 4 ] but natural substances in skin care products include animal-derived products such as beeswax , and minerals.
Skin care is at the interface of cosmetics [4] and dermatology. [5] The US Federal Food, Drug, and Cosmetic Act defines cosmetics as products intended to cleanse or beautify (for instance, shampoos and lipstick). A separate category exists for medications, which are intended to diagnose, cure, mitigate, treat, or prevent disease, or to affect ...
This was inspired by student requests, as well as a lack of existing products that Jane Wurwand could use on her skin, which experienced dermatitis and chronic eczema. [6] [9] Dermalogica was created and premiered in 1986 as a skin care line, sold in concept spaces and in authorized salons, spas, and beauty supply stores.

There was once a time when Kelly Ripa, like most of us, had just one beauty secret: youth. But as she approached her 40th birthday, the actress and TV host decided a strict anti-aging skincare ...
Polygalacturonase is a pectinase, an enzyme that degrades pectin by hydrolyzing the O-glycosyl bonds in pectin's polygalacturonan network, resulting in α-1,4-polygalacturonic residues. [10] The rate of hydrolysis is dependent on polysaccharide chain length. Low rates of hydrolysis are associated with very short chains (e.g. digalacturonic acid ...
