Sorghum: Nutritional Benefits, Processing Steps, and Food Products for a Healthy Lifestyle

Sorghum, scientifically known as Sorghum bicolor, stands out as a versatile cereal grain plant within the Poaceae family, prized for its hardy nature and nutritional value. Originating in Africa, this crop has garnered diverse monikers worldwide; in India, it is referred to as jowar, cholam, or jonna, while in West Africa, it is known as Guinea corn, and in China, as kaoliang.

This resilient crop thrives in hot and arid climates, boasting remarkable tolerance to drought and heat stress. With its roots in ancient agriculture, sorghum has emerged as a crucial staple for many communities globally, serving not only as a source of nourishment but also as fodder for livestock and even as raw material for making brooms.

Nutritionally dense, sorghum grain offers a valuable combination of protein, dietary fiber, essential B vitamins, and minerals, making it a vital component of diets across cultures. As interest in sustainable and climate-resilient crops grows, sorghum continues to gain attention for its adaptability and nutritional benefits in diverse agricultural landscapes.

This robust grass typically grows to a height of 0.6 to 2.4 meters, boasting stalks and leaves coated with a protective white wax. Some varieties even reach towering heights of 4.6 meters. The leaves are broad, measuring about 5 cm, and the plant produces tiny flowers in panicles that range from loose to dense, with each flower cluster bearing 800–3,000 kernels. Although sorghum seeds come in diverse colors, shapes, and sizes, they are generally smaller than wheat grains.

Sorghum, while considered of lower feed quality than corn (maize), compensates with its nutritional value. It is high in carbohydrates, containing 10 percent protein and 3.4 percent fat, along with calcium, iron, vitamin B1, and niacin in smaller amounts. This gluten-free grain is a staple in many diets, consumed in the form of porridge, flatbreads, and cakes.

Additionally, it is used in the production of edible oil, starch, dextrose, paste, and alcoholic beverages. The stalks serve as valuable fodder and building materials, showcasing the plant’s versatility.

In its early stages of growth, certain sorghum species may contain levels of hydrogen cyanide, hordenine, and nitrates lethal to grazing animals. Plants stressed by drought or heat can also contain toxic levels of cyanide and nitrates at later stages of growth.


Sorghum, scientifically known as Sorghum bicolor, is a staple grain known for its rich nutritional composition. This versatile grain is primarily composed of carbohydrates, making it an excellent energy source for daily activities. Sorghum also contains vital minerals such as iron, promoting healthy blood circulation, and phosphorus, essential for bone health.

Additionally, its high dietary fiber content supports digestive health, aiding in proper digestion and preventing constipation. Notably, sorghum is naturally low in fat and is gluten-free, making it a suitable option for individuals with dietary restrictions.

Sorghum grain is a nutritional powerhouse, comprising 72% carbohydrates (including 7% dietary fiber), 11% protein, 3% fat, and 12% water. In a 100-gram serving, sorghum provides 79 calories and rich contents of several B vitamins and dietary minerals. All sorghums contain mixed polyphenols, making them one of the highest food sources of proanthocyanidins.


Sorghum offers a range of health benefits that make it a valuable addition to a balanced diet. Its low-fat content contributes to heart health, reducing the risk of cardiovascular diseases. The high dietary fiber content aids in maintaining a healthy digestive system, promoting regular bowel movements.

Sorghum is rich in essential minerals, including iron, which is crucial for preventing anemia, and phosphorus, supporting bone strength. Including sorghum in your diet can contribute to overall well-being and nutritional balance.


Sorghum is a versatile grain that finds its way into a variety of traditional and modern food products. In traditional cuisines, sorghum is commonly used to make staple items like sorghum roti or jowar bhakri. Modern food trends have introduced innovative sorghum-based products, including snacks, flour, and breakfast cereals. The adaptability of sorghum makes it suitable for diverse culinary applications, catering to different tastes and preferences.


  1. Cleaning the Sorghum Grains: The first step involves cleaning the sorghum grains to remove any impurities.
  2. Conditioning the Grains: The cleaned grains are then conditioned by adding water. This helps to soften the endosperm, the inner part of the grain.
  3. Dry Milling: Dry milling is initiated, where the conditioned grains go through conventional roller mills. The process separates the endosperm, germ, and bran from each other.
  4. Pearling or Decortications: An alternative milling process for sorghum is called ‘pearling’ or decortications. Cleaned grains are wetted by spraying water for 2-3 minutes. Immediately, they are milled in a rice huller to remove coarse fiber, pigment, and photons from the grain. This process minimizes grain cracking and allows up to 12 percent polishing.

Pearling produces products rich in protein, up to 27 percent, high in fat, and with a high ash yield. However, these products are low in fiber. They are particularly useful in preparing food products with high protein content.

Sorghum processing yields products with high protein content, making them valuable for various food preparations. The versatility of sorghum extends to malting, providing options for both food and pharmaceutical industries.
