Starch, found in essentials like wheat and rice, is indispensable to our diet and myriad industries. Its granules, however, differ in size and shape between crops. For wheat, there are the A-type and the smaller B-type granules.
These granule types influence the texture of wheat-derived foods and pose challenges in starch production. Many B-type granules get wasted during milling, while their presence in barley may result in less clear beer.
A game-changing finding has emerged from the John Innes Centre, led by Dr. David Seung. Pinpointing the enzyme PHS1 as crucial for B-type granules, the team used techniques to minimize these granules in wheat without hampering its overall health or starch content.
"The role of PHS1 provides insights for tailoring starch for diverse applications," says Dr. Nitin Uttam Kamble, the leading author. Dr. Seung perceives vast potential for industries given this revelation, as it addresses longstanding challenges.
Wheat starch plays a big role in Europe's industry. In the past, industries have devised ways to manage the A- and B-type granule mix, which incurred additional costs. This discovery could revolutionize these processes, optimizing costs and efficiency.
Beyond industry, this research holds implications for understanding starch's nutritional significance. Altering starch in plants might sidestep current expensive and environmentally taxing modification methods.
