Why is the global starch industry important?
The starch industry is at the very heart of food production: supplying hundreds of ingredients for use in thousands of food products and animal feed.
At the same time, starches play a vital role in a wide variety of products beyond food. Natural and modified food starches can be found in products and processes in the consumer products, pharmaceutical, energy, industrial and chemical sectors.
With the world beginning a gradual shift away from fuels as the primary engine of economic prosperity, there will be a larger opportunity for starch producers to contribute renewable, sustainable materials through the economy.
Starch is primarily extracted from corn, wheat, tapioca, potatoes, rice, and other plant feedstocks. Each raw ingredient yields a different amount of starch, which varies greatly.
Starches have been used throughout history and are now most commonly used in the food and paper industries.
While starch is produced commercially from many different crops, it is most widely obtained from corn, wheat, rice, potato, and cassava.
Starch is a primary foodstuff and acts as a key source of carbohydrates in global food production.
Filtration fulfills an important role in starch production
The process, from the agricultural crop (grain or root) to starch and its derivatives is bristling with solid-liquid separation and classification steps, from screening to removing fibers and husks through to the final filtration and washing process prior to thermal drying.
The starch industry is a very large consumer of water (nearly all of which ultimately leaves the plant either in a waste stream or as water vapor from dryers/evaporators). Minimizing the use of water can be a key factor in the success of a starch plant.
