Sprouted Rice Reduces Common Allergens

While very few people are allergic to rice, when allergies do occur they are usually linked to specific proteins. Japanese researchers found that sprouted brown rice was much lower in two abundant allergens, when compared to non-sprouted brown rice, and that the reduction was probably caused by protease (enzyme) activity during germination.

Optimum Germination Conditions for Wheat

Scientists at the University of Alberta germinated wheat under various conditions to determine how to maximize the production of antioxidants.  First, they steeped the grains in water for 24 or 48 hours, then sprouted them in the dark for 9 days. Vitamins C and E and beta-carotene, which were barely detectable in the dry grains, increased steadiily during the germination period. Grains steeped for 48 hours became wet, sticky, discolored and acidic-smelling after germination, leading researchers to conclude that 24 hours of steeping and 7 days of sprouting would produce the best combination of antioxidant concentrations and sensory properties.

Sprouting Sorghum Enhances Taste and Nutrition

Tanzanian researchers observed that sorghum, although a staple food in many poorer areas of the world, is not highly esteemed, because of limits in its nutritional and sensory qualities. In an effort to make this easy-to-grow grain more useful and more widely accepted, they studied three traditional processing methods: germination (sprouting), fermentation, and a germination/fermentation comination.  They concluded that germination was the best approach for improving the nutritional and functional qualities of the sorghum.

Sprouted Millet is Higher in Key Nutrients

Researchers in India allowed proso millet to germinate for 1-7 days, then analysed the changes in its composition. They found that sprouting increased lysine (a key amino acid lacking in most grains) and concentrated the protein, as the grain overall lost weight. Increases in tryptophan, albumin and globulin were also observed, along with decreases in prolamins, a plant storage protein that may be difficult for some people to digest.

Digestibility Changes in Sprouted Barley

In an experiment at the University of Alberta, barley kernels were sprouted from 2 to 5 days, then oven-dried and milled. Researchers found decreases in dry matter, gross energy (calories) and triglycerides, and increases in fiber and diglyceride content. After the sprouted barley was fed to rats, scientists said that “digestibility data showed an enhancement of digestibility of nutrients in barley… implying that sprouting improved nutritional qualify of barley.”

Nutritional Improvement of Cereals by Sprouting

In a 1989 meta-analysis of existing studies, JK Chavan and SS Kadam found evidence that “Sprouting of grains for a limited period causes increased activities of hydrolytic enzymes, improvement in the contents of certain essential amino acids, total sugars, and B-group vitamins, and a decrease in dry matter, starch, and antinutrients. The digestibilities of storage proteins and starch are improved due to their partial hydrolysis during sprouting.”
