Influence of Processing on Trypsin Inhibitor Activity of Faba Beans and Its Physiological Effect
نویسندگان
چکیده
Changes in the trypsin inhibitor activity (TIA) of faba beans (Vicia faba L. Major) were investigated after beans were soaked in distilled water, citric acid, and sodium bicarbonate solutions. The soaking solution was discarded. The effect of cookingsdiscarding both soaking and cooking solutionsswas also studied. Finally, a dry-heating process was examined. Soaking treatment produced a slight decrease of trypsin inhibitor activity. Cooking the presoaked seeds brought about the total or partial removal of TIA, depending on the soaking solution used. TIA was partially removed after dryheating. Trypsin inhibitor activity analyses were completed with 28-day biological trials for raw and dry-heated faba beans. For 21 and 28 days of experimental time food intake, protein intake, and weight gain were similar for rats fed raw and dry-heated faba beans. However, after 28 days protein efficiency ratio (PER) and food transformation index (FTI) improved in rats fed dry-heated faba beans compared with those fed raw faba beans. This was related to lower TIA values found in dry-heated faba beans.

A total of adult leghorn roosters and 360 day-old broiler chicks were used in two completely randomized experiment to evaluate metabolizable energy (ME) and feeding value of faba beans in broiler rations. In a factorial arrangement with 10 treatments and 3 replicates chicks were fed isonitrogenous rations containing either 0, 10, 20 or 30 percent of raw, cooked or dehulled faba beans for 8 week...

متن کاملTrypsin inhibitor activity in the field bean (Vicia faba L.).
Wilson and McNab' reported an increase in live-weight and a reduction in pancreas size of chicks when field beans (Viciu fabu L.) were autoclaved at 120 "C for 30 min. Such effects may be due to the presence in the raw field bean of a trypsin inhibitor analogous to those found in the soyabean and other legumes. Information on the presence of trypsin inhibitors in the field bean and on growth of...

Seed samples from two near-isogenic faba bean (Vicia faba L.) lines were examined for the levels of so-called anti-nutritional factors (ANF). From the ANF known to be present in faba beans, trypsin inhibitor activity, functional lectins, condensed tannins and pyrimidine glycosides were analysed. It was concluded that the lines differed only in the content of condensed tannins being < 0.5 g/kg a...
