GrainFrac,a Canadian leader in providing fibre and protein solutions to food and beverage manufacturers, uses non-GMO Canadian barley to extract beta-glucan fibre as an ingredient with cholesterol lowering benefits. Beta-glucan is a soluble dietary fibre ingredient present in the cell walls of whole grains, such as barley and oats, and is a natural ingredient with multiple proven health benefits. After carefully extracting the fibre with a method that does not use solvents or enzymes, fibre-depleted flour starches are obtained as byproducts. This fibre-depleted flour is currently sold as low-cost animal feed or sent to landfill. The goal of this project is to evaluate the potential conversion of this product into high-value fermentable sugars with applications as biofuels or biochemicals and provide GrainFrac with actionable knowledge to refine this process and expand into new markets. This project will also improve our knowledge of enzymatic reactions on impure starch byproducts resulting from the emerging field of bioactive ingredient production. This project will contribute to improving the economic and environmental competitiveness of Canadian manufacturers of plant-based bioactive ingredients by providing access to new markets and reducing disposal costs and promote circular economics by reducing the volume of byproduct materials sent to landfill.

GrainFrac是加拿大领先的食品和饮料制造商纤维和蛋白质解决方案提供商，使用非转基因加拿大大麦提取β-葡聚糖纤维作为降低胆固醇的成分。β-葡聚糖是一种可溶性膳食纤维成分，存在于大麦和燕麦等全谷物的细胞壁中，是一种具有多种健康益处的天然成分。在用一种不使用溶剂或酶的方法仔细提取纤维后，作为副产品获得了纤维耗尽的面粉淀粉。这种纤维耗尽的面粉目前作为低成本动物饲料出售或送往垃圾填埋场。该项目的目标是评估该产品转化为高价值可发酵糖的潜力，并将其应用于生物燃料或生物化学品，并为GrainFrac提供可操作的知识，以完善该过程并扩展到新市场。该项目还将提高我们对新兴生物活性成分生产领域产生的不纯淀粉副产物的酶促反应的认识。该项目将通过提供进入新市场的机会和降低处置成本，促进加拿大植物生物活性成分制造商的经济和环境竞争力，并通过减少送往垃圾填埋场的副产品数量促进循环经济。
