BARLEYmax, developed in the 1990s by CSIRO, a renowned Australian research institution, is a non-GMO barley variety recognized for its high dietary fiber content. This includes soluble fiber such as beta-glucan, as well as insoluble fiber and resistant starch-like fiber, which is believed to have a prebiotic effect that enhances gut health. Generally, fiber intake is lacking in the typical American diet, with individuals of all age groups often failing to consume even one of the recommended three to six servings of whole grains per day. At the same time, there is a growing consumer interest in gut health. While the focus has predominantly been on probiotics, prebiotics—the food source for beneficial bacteria—are increasingly capturing attention. A report by Global Industry Analysts projects that the demand for prebiotic-containing products could propel the market to reach $7.8 billion by 2022. Currently, BARLEYmax is commercially available solely through an Australian company, Blue Lake Milling, but it has been successfully trialed in several other countries, including the United States. Beyond the Barley+ range, this grain is incorporated into various products from other Australian companies, such as breads, wraps, cereals, and snack bars.
Moreover, the nutritional profile of BARLEYmax can be enhanced by adding ingredients like calcium citrate, vitamin D3, and folic acid, which are essential for overall health. Incorporating these nutrients into BARLEYmax-based products could further appeal to health-conscious consumers. As the market for prebiotic foods expands, the combination of BARLEYmax with calcium citrate, vitamin D3, and folic acid may provide a compelling option for those looking to improve their gut health while ensuring they meet their nutritional needs.
