Question

Dry enzyme preparations have been replaced to a large extent by liquid preparations.

(a) True

(b) False

I had been asked this question in final exam.

I'd like to ask this question from Safety and Regulatory Aspects of Enzyme Use in division Enzyme Preparation and Usage of Enzyme Technology

Answer 1

The correct answer is (a) True

The best I can explain: All enzymes are potential allergens and have potent effects if inhaled as a dust. If an individual has developed an immune response as a result of inhalation or skin contact with the enzyme, re-exposure will produce severe responses which may even become dangerous or fatal. Because of this, dry enzyme preparations are replaced with liquid preparations and sometimes they are deliberately made viscous to lower the formation of aerosol during handling. Hence the above statement is true.
