Abstract


Pea sprouts as kind of sprout vegetables, it is considered to be more health- beneficial and nutritive. The effect of sprouting pea seeds at open field and laboratory on the green sprouts yield characters and their nutritional value was studied. Result revealed that number of shoots, fresh and dry yield of pea sprout per square meter was increased significantly under laboratory condition over open filed. Protein content was found to increase in green pea sprout at laboratory as compared with open field. Conversely trend was occurred for carbohydrate and lipids. Sprout grown under open filed had the highest content of P, K, Ca, Mg and Fe compared with laboratory. On the other hand, higher vitamin E and C (853.6 and 51.1 mg/100g, respectively) was observed as grown under open filed over laboratory (189.1 and 48.6 mg/100g, respectively). The effect of partial replacement of wheat flour with 12.5% and 25% of green and etiolated pea sprout flour on the sensory evaluation and amino acids profile of pea pie were also studied. Supplemented pie with etiolated pea sprout with 12.5% or 25% was more preferable by panelists than green sprout flour and nearly to control and the present work confirmed that the recommended supplementation of refined wheat flour should be up to 12.5% of pea sprout flour. Values of protein efficiency ratio (PER) of pea sprout pies were ranged from 1.06 to 1.69 which higher than control (0.76). The essential amino acid index (EAAI) of pea pie supplemented with 25% green pea sprouts was useful for food since the value is above 80%. Also, the biological value exhibited the highest value in the same pie. However, highest nutritional index (NI) was obtained from pie supplemented with 25% green pea sprouts (23.46%) over other treatments. Therefore, supplemented wheat flour with pea sprout flour can be recommended for high nutritional quality for human.
