“…These results are in agreement to those reported by earlier reports (Cevallos-Casals & Cisneros-Zevallos, 2010;Dueñas, Hernández, Estrella, & Fernández, 2009). In contrast, Khandelwal, Udipi, and Ghurgre (2010) and Swieca, Gawlik-Dziki, Kowalcyk, and Złotek (2012) detected reductions of total polyphenols in Indian pulses due to the increase of polyphenol oxidase activity and other catabolic enzymes.…”

“…Modifi cations of sprouting aimed at overproducing antioxidants usually involve induction of the natural mechanisms of plant resistance (Gawlik-Dziki et al, 2013;Pérez-Balibrea et al, 2011;Świeca et al, 2012;Tsurunaga et al, 2013); however, there are only a few studies concerning the mechanisms of obtaining desirable features. Elicitations usually induce a plant response cascade including inter alia changes in the activities of some enzymes, among which peroxidase, polyphenol oxidase and phenylalanine/tyrosine ammonia lyases should be mentioned.…”

“…So far, studies aimed to improve the antioxidant composition of sprouts have involved optimizing biosynthesis through the modifi cations of culture conditions (Khattak et al, 2007;Shett and McCue, 2003;Świeca et al, 2012), precursor feeding and biotransformation (Pérez-Balibrea et al, 2011;Świeca et al, 2014c), as well as elicitation and stress induced production (Gawlik-Dziki et al, 2013;Kim et al, 2011;Tsurunaga et al, 2013;Świeca, 2015). Elicitors increase the activity of key enzymes involved in the synthesis of low-molecular antioxidant e.g.…”

An increased interest has been noticed in the modifi cation of food along each step of its production (breeding, production technology, storage condition). Briefl y speaking nutritional properties as well as the level and activity of bioactive compounds present in plant-origin food may be modifi ed using a range of technological ELICITATION AND TREATMENT WITH PRECURSORS OF PHENOLICS SYNTHESIS IMPROVE LOW-MOLECULAR ANTIOXIDANTS AND ANTIOXIDANT CAPACITY OF BUCKWHEAT SPROUTS ABSTRACTBackground. Recently, an increase of interest in the modifi cation of food products on each step of production (breeding, production technology, storage condition) is observed. Nutritional properties as well as level and activity of bioactive compounds in plant-origin food may be modifi ed using a range of technological and biotechnological practices and elicitation should be mentioned between them. Material and methods. Elicitation with willow bark infusion supported by feeding with the phenylpropanoid pathway precursors were used for improving the quality of buckwheat sprouts. Special emphasis has been placed on the metabolomic and biochemical changes and the mechanism of overproduction of low--molecular antioxidants.Results. The accumulation of phenolics is caused by stimulation of two main enzymes the phenylpropanoid pathway (tyrosine ammonia-lyase and phenylalanine ammonia-lyase). Tyrosine ammonia-lyase activities were eff ectively induced by feeding with tyrosine (about four times that of the control), whereas phenylalanine ammonia-lyase activity was the highest in the elicited control sprouts and those fed with shikimic acid (an increase by 60% compared to the control). Shikimic acid feeding (both elicited and non-elicited sprouts) eff ectively improved the total phenolics (by about 10% and 20%, respectively), condensed tannins (by about 30% and 28%, respectively), and fl avonoids (by about 46% and 70%, respectively). Signifi cant increase of vitexin, rutin, chlorogenic acid and isoorientin contents was also observed. The treatments increased the ascorbic acid content, too. Total antioxidant capacity of sprouts was most eff ectively increased by feeding with shikimic acid and further elicitation. Conclusion. The studies transfer biotechnology commonly used for the induction of overproduction of secondary metabolites in plant cell line systems to low-processed food production. The obtained results could be used for better understanding of the eff ect of elicitation and precursor feeding on antioxidants production and contribute to improving the buckwheat sprouts quality.

“…Previous studies have shown that phytochemicals of legumes can be increased after germination, suggesting that legume sprouts may provide desirable health benefits beyond basic nutrition. In this sense, the improvement of the antioxidant activity of legumes during germination due to an increased content of polyphenols and vitamin C has been reported by several authors [4][5][6]. Germination also improved the levels of GABA [7], a compound involved in the regulation of blood pressure [8], and promoted the liberation of bioactive peptides in diverse legumes [9].…”

The aim of this study was to investigate the application of elicitors (500 μM ascorbic acid, 50 μM folic acid, 5 mM glutamic acid and 50 ppm chitosan in 5 mM glutamic acid) during lentil germination up to 8 days as a strategy to increase germination rate and to enhance the accumulation of γ-aminobutyric acid (GABA) and phenolic compounds. The effect of elicitation on the protein profile and antioxidant and angiotensin I converting enzyme (ACE) inhibitory activities of sprouted lentils was also evaluated. The application of elicitors did not negatively affect the germination yield of lentils and no significant changes on the protein pattern of lentils germinated in the presence of elicitors were observed. Chitosan/glutamic acid increased by 1.6-fold the GABA content in lentil sprouts, whilst ascorbic and folic acids as well as chitosan/glutamic acid were highly effective to enhance the total content of phenolic compounds and the antioxidant activity of sprouted lentils. All elicited lentil sprouts showed ability to inhibit ACE activity (IC50: 9.5-11.9 μg peptides/mL). Therefore, elicitation can be considered a promising approach to improve the content of compounds with antioxidant and potential antihypertensive activities in lentil sprouts.
