Sorghum is a versatile crop used globally for a variety of purposes, including food, animal feed, biofuel, and industrial applications[1].
Major uses of sorghum include:
- Food for humans: Sorghum grain is widely consumed and increasingly found in baked products (bread, flatbreads, tortillas, muffins, crackers), cereals, snacks, entrees, food bars, and confections. It can be eaten whole, popped like popcorn, ground into flour for gluten-free baking, or malted into syrup as a sweetener[5][7]. It is naturally gluten-free and rich in nutrients, making it popular in the health food and specialty diet markets.
- Livestock feed: Sorghum is a significant component of feed for poultry, beef, dairy cattle, swine, ducks, as well as being used in aquaculture and pet food. Both the grain and the plant’s stems and foliage are used for green chop, hay, silage, and pasture[1][2][6].
- Renewable energy (biofuel): Traditionally, about a third of the U.S. sorghum crop is used in ethanol production. Sorghum is valued for being water-efficient and producing ethanol at yields comparable to other feedstocks, while using less water and nitrogen fertilizer[1][3][4].
- Industrial products: Sorghum is processed to produce grits, flour, meal, syrup, and waxes. The sugars from sweet sorghum can be fermented to make biofuels (ethanol, hydrogen, butanol), biodegradable plastics (polylactic acid), and chemicals such as lactic acid and acetone[3][4][6].
- Other uses: In various countries, red sorghum leaves are used for dyeing leather and wool, and the stalks can be used as broom bristles[3]. Sorghum is also found in films and coatings for food packaging[4].
