In the current research, wheat grains were used to study the effect of grain soaking and sprouting using tap water and saline water (NaCl solution) on sprout growth, proximate analysis, minerals content, anti-nutritional and antioxidant compounds of sterilized grains (soaked for 0.33h) and soaked grains for imbibition (12h) and sprouted grain for 24h old. Results revealed that the longest radical of 24h old wheat sprout was observed at 2000 ppm NaCl, and shortest was observed at 4000 ppm NaCl. Soaked wheat grains (12h) for imbibition recorded the highest moisture content (10.2 to 10.9%) while soaked for 20 min (0.33h) in calcium hypochlorite for sterilization recorded medium content (8.8 to 9.9%) and the lowest one recorded in 24h old wheat sprouts (6.9 to 7.2%). The low moisture content the high total carbohydrate, total fats and energy and vice versa. Soaked grains for sterilization period (0.33 h) and imbibition (12h) increased zinc (Zn), manganese (Mn) and calcium (Ca) while non-sterilized only potassium (K). Tap water increased sprout magnesium (Mg), and manganese (Mn) content while saline water increased sprout magnesium (Mg), and calcium (Ca) content. Grain sprouting was effective in reducing phytic acid, oxalate and alkaloids anti-nutrient in wheat sprouts especially when using sterilized grains. Soaking non sterilized grains for imbibition (12h) in saline water contained higher total phenol, flavonoids and total antioxidant. Etiolated wheat sprouts contained lower total flavonoids and antioxidant compared with soaked grains in saline water.

nsidered 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 values were 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 ones. On the other hand, higher vitamin E and C (853.6 and 51.1 mg/100g, respectively) was observed as grown under open filed than 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. 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, combination of wheat flour with pea sprout flour can be recommended for high nutritional quality for human, Since it have good protein quality because the amino acid compositions of wheat and peas complement each other, producing a balanced mixture of amino acids.
