A hemp protein product, which may be an isolate, produces solutions at low pH values and is useful for the fortification of soft drinks and sports drinks without precipitation of protein. The hemp protein product is obtained by extracting a hemp protein source material with an aqueous calcium salt solution to form an aqueous hemp protein solution, separating the aqueous hemp protein solution from residual hemp protein source, adjusting the pH of the aqueous hemp protein solution to a pH of about 1.5 to about 4.4 to produce an acidified hemp protein solution, which may be dried, following optional concentration and diafiltration, to provide the hemp protein product.本發明係關於一種可為單離物之大麻蛋白質產物，其在低pH值下形成溶液，適用於強化軟飲料及運動型飲料，不會出現蛋白質沉澱。大麻蛋白質產物製法係藉由利用鈣鹽水溶液萃取大麻蛋白質源物質，形成大麻蛋白質水溶液，將該大麻蛋白質水溶液與殘留大麻蛋白質源分離，將該大麻蛋白質水溶液之pH調整至約1.5至約4.4之pH，產生酸化大麻蛋白質溶液，其可在視需要濃縮及透濾之後乾燥，產生大麻蛋白質產物。
