“…Similar observations were made by Fouad and Rehab (2015), which studied the effects of germination time on lentil sprouts. They observed an increase of TPC during germination with the maximum level at 5-day lentil sprouts, followed by a decrease, which they proposed as due to mobilization of stored phenolics by the activation of enzymes like polyphenol oxidase (Fouad and Rehab, 2015). Activation of polyphenol oxidase could also explain the decrease of TPC in the 7-day broccoli and 9-day cauliflower sprouts of the present work.…”

Sprouts are very rich in antioxidants (e.g. phenolic compounds) and their consumption is beneficial for humans' health. The sprouts' antioxidant properties are correlated to conditions of growth and maturity stage. The present study reveals the influence of maturity stage (5-, 7-and 9-day-old) and two sodium salts, NaCl and Na 2 SO 4 (10 mM and 100 mM) on the antioxidant capacity and total phenolic content of cauliflower and broccoli sprouts. The analysed sprouts' extracts were obtained in two phases, using ethanol 70% with 0.01% hydrochloric acid. In the case of cauliflower, the 7 days germination leads to the highest total phenolic content and radical scavenging capacity. Broccoli sprouts revealed the most enhanced DPPH radical scavenging capacity and total phenolic content at 5-day-old. The two sodium salts, generally, had positive effects on global antioxidant status. It is highlighted both for broccoli and cauliflower, the stimulating effect of 100 mM Na 2 SO 4 on the total phenolic content and soluble dry weight, but the DPPH radical scavenging activity was more important in the case of NaCl, than Na 2 SO 4 treatments, except for cauliflower sprouts treated with 100 mM Na 2 SO 4 . In conclusion, germination under adequate salt stress is a protocol to be considered in order to improve antioxidant properties of broccoli and cauliflower sprouts, despite the non-convenient effects on the germination and sprouts growth. Further researches are needed to optimize the level and time periods of such treatments.

“…Fouad and Rehab (2015) also found that germination caused a significant increase in DPPH radical scavenging activity, total phenolic content and free amino acid content in germinated lentils (p≤0.05). Similar results were also found in germinated mung bean (Wongsiri et al, 2015) These results also demonstrated that the influence of extraction solvent on measured antioxidant activities of rice bean extracts was remarkable.…”

AbstractThis research evaluated effect of germination period and acid pretreatment on chemical composition and antioxidant activity of rice bean sprouts. Moisture, total phenolics, reducing sugar and B vitamins (thiamine, riboflavin, and niacin) content of steamed sprouts increased with increasing germination time (p≤0.05). Pretreatment with 1% (w/v) citric acid for 6 hours significantly increased the total phenolic content. The 18-hour-germinated rice beans showed the highest crude protein content, as determined using the Kjeldahl method. During germination, acid pretreatment led to a significant decrease in the intensity of the 76-kDa band. Germination caused a significant increase in radical scavenging activity and ferric reducing antioxidant power, especially in sprouts from citric acid-treated seeds. The antioxidant activities of the ethanolic extracts from both pretreated beans and the control were 1.3-1.6 times higher than those obtained from the water extracts. Major phenolics found in both 0-hour and 18-hour-germinated rice beans were catechin and rutin.

“…An increase in protein content was observed in germinated lupin (Rumiyati et al 2012). In contrast, Fouad and Rehab (2015) reported a reduction in sulfur amino acids and increased lysine in germinated lentils. Germination and enzymatic hydrolysis of the protein can affect the amino acid profile.…”

Cereal Chem. 94(1):11-31The United Nations has declared 2016 as the International Year of Pulses. Pulses are narrowly defined as leguminous crops that are harvested as dry seeds. Although some pulse crops are harvested green (e.g., green peas), these are classified as vegetables because the pods are often consumed along with the mature and sometimes immature seeds.Other dried legumes such as soybean and peanut meet the definition of being a leguminous crop that is harvested as dry seeds; however, these crops are grown primarily for oil content and, thus, are not categorized as pulses. There are hundreds of pulse varieties grown worldwide; these include, for example, dry edible beans, chickpeas, cowpeas, and lentils. This review will cover the proximate (e.g., protein, carbohydrates, vitamins, and minerals), and phytonutrient (e.g., polyphenolics and carotenoid) composition of dry edible beans, peas, lentils, and chickpeas. Soybean and peanuts will not be covered in this review. The effects of processing on composition will also be covered. The health benefits related to folates, fiber, and polyphenolics will be highlighted. The health benefits discussed will include cardiovascular disease, cancer, diabetes, and weight control. The current review will not cover antinutrient compounds; this topic will be covered in a separate review article published in the same issue. † Corresponding
