Industrial chemical manufacture general case

In the case of patents, US or GB numbers have usually been quoted, although they do not, of course, necessarily represent the country of origin. Cited patents are intended to be illustrative rather than exhaustive. This book does not attempt to provide details of the design and operation of industrial chemical plants. It does, however, acknowledge the importance of the chemical engineer, without whom phosphorus compounds could not not be manufactured and made available, at reasonable cost, to the general public. This is particularly applicable to the products dealt with in Chapter 12. 

Most food powders are not directly consumed by humans and animals, they are usually mixed with water and other liquids to produce wet formulations, which are further processed to produce products that are directly consumed. As a result of being ultimately consumed by humans and animals, prevention of contamination of the powders with microorganisms, viruses and undesirable chemical components is a huge issue for food powder manufacturers and the food industry in general. One major case of food poisoning linked to a contaminated powder can be very detrimental to a producer.
