A beginner’s guide to enzymes in detergents | Novozymes- why washing powder manufactures have produce protease which can work at temperature higher than 40 ,Tests conducted by Novozymes on an EU front-loader under conditions of 40°C, 15°dH, detergent containing bleach, dosage of 65 - 110 g/14 L wash found that standard protease shows great residual wash performance after regular accelerated storage conditions, while protease with the new stabilizer is superior also after tough accelerated conditions.Pectinases - an overview | ScienceDirect TopicsMany Pseudomonas species, such as P. fluorescens and Pseudomonas fragi, can degrade the globular casein proteins in milk, especially the β-, αS1-, and κ-caseins, but not the whey proteins. Many of the proteases produced by Pseudomonas species are stable to heat and survive ultra-high temperature processing; this can cause problems in long ...

Moreover, tests have shown that the lysine keeps much longer, thanks to the absence of lactose in the environment. This suggests that milk proteins can be more conveniently stored in the form of casein and caseinate than, for example, as dried milk powder. Casein produced for industrial use must satisfy long-established demands for chemical purity.

Laundry detergent - Wikipedia

Laundry detergent is a type of detergent (cleaning agent) used for cleaning dirty laundry (clothes). Laundry detergent is manufactured in powder (washing powder) and liquid form..
