Abstract

There is a great interest of the industry on food components physiologically active in flaxseed, besides the hypoglycemic effect of soluble fiber, which could be useful in developing specific polymer drinks for diabetics. In order to compare the chemical composition on whole and ground seeds of a Canadian variety of Linum usitatissimum L. and also to determine the effect of ground flax fiber on the glycemic and insulin response in a carbohydrate selected drink in healthy adults as an alternative to design foodstuffs in controlling diabetes mellitus. Moisture, protein, fat, ash, total dietary fiber (soluble and insoluble) were determined, plus hydrocyanic acid HCN equivalent. Two different fiber concentrations in commercial beverage to study their glycemic response were used; the original (BP): fiber 0.77 g.100 mL-1 and the modified (BPL) to add ground flaxseed (3.33 g.100 mL-1). Significant differences in all chemical variables on both seed samples except ashes were observed. The amount of HCN found in the ground sample was not unsafe for human consumption and was significantly reduced by the roasting process. The glycemic index was intermediate and lower for BPL (56.40±6) than for BP (58.07±8); glycemic load was intermediate, with no significant increase in the insulin. This suggests a possible decrease in the rate of absorption of glucose in the blood with addition of fiber flaxseed.
