Processing bioactive peptides from natural sources using electrodialysis with ultrafiltration membranes(EDUF)have gained attention since it can fractionate in terms of their charge and molecular weight.Quinoa is a pseudo-cereal highlighted by its high protein content,amino acid profile and adapting growing conditions.The present work aimed at the production of Quinoa peptides through fractionation using EDUF and to test the fractions according to antihypertensive and antidiabetic activity.Experimental data showed the production of peptides ranging between 0.4 and 1.5 k Da.Cationic(CQPF)(3.01%),anionic(AQPF)(1.18%)and the electrically neutral fraction Quinoa protein hydrolysate(QPH)-EDUF(~95%)were obtained.In-vitro studies showed the highest glucose uptake modulation in L6 cell skeletal myoblasts in presence of QPH-EDUF and AQPF(17%and 11%)indicating potential antidiabetic activity.The antihypertensive effect studied in-vivo in spontaneously hypertensive rats(SHR),showed a decrease in systolic blood pressure in presence of the fractionated peptides,being 100 mg/kg a dose comparable to Captopril(positive control).These results contribute to the current knowledge of bioactive peptides from Quinoa by reporting the relevance of EDUF as tool to produce selected peptide fractions.Nevertheless,further characterization is needed towards peptide sequencing,their respective role in the metabolism and scaling-up production using EDUF.

Pre-harvest sprouting(PHS)will have a serious effect both on the yield and quality of Quinoa(Chenopodium QuinoaWilld.).It is crucial to select and breed Quinoa varieties with PHS resistance and excellent agronomic traits for guidance production and utilization of Quinoa.A comprehensive evaluation of the PHS resistance and agronomic traits of 37 species of Quinoa resources was conducted in Chengdu Plain.The evaluation used various methods,including grain germination rate(GR),grain germination index(GI),total spike germination rate(SR),total grain germination index(SI),grey correlation analysis(GCA),cluster analysis and correlation analysis.Results showed significant differences in PHS resistance and agronomic traits amongst the 37 Quinoa resources.CDU-23 was most resistant to PHS within 24 h,with a germination rate of 2.67%and 0%according to the GR and SR results,respectively.However,in the same time,CDU-31 showed the maximum susceptibility to PHS based on the SR of 31.07%,while CDU-34 was the most sensitive to PHS according to the GR of 100%.The comprehensive evaluation identified one and nine kinds of high resistance species for grain and whole spike germination,respectively.In both cases,the coefficients of variation(CV)for these parameters were 34.78%and 82.13%,respectively.GCA results showed that the magnitude of the association between each trait and yield in the thirty-seven Quinoa resources was in the following order:thousand grain weight>seed length>seed area>seed width.Although the seed weight of CDU-18 reached 3.7010 g,the seed weight of CDU-5 was only 1.6030 g.However,the size of the seeds,their width and area did not correlate with their 1000-grain weight.There was a complex correlation between PHS resistance index and agronomic traits.Based on clustering analysis,thirty-seven Quinoa resources were classified into three taxa.It was found that various taxa differed in PHS resistance and agronomic traits.Several comparisons of the aggregated data led to the selection of five varieties of Quinoa,of which

Biofiltration of the antibacterial drug sulfamethazine by the species Chenopodium Quinoa and its further biodegradation through anaerobic digestion

引用

Journal of Environmental Sciences 2019年第1期31卷 54-63页

作者： Ariel E.Turcios Jutta Papenbrock Institute of Botany Leibniz University Hannover

The biofiltering capacity, distribution patterns and degradation of the antimicrobial sulfamethazine(SMT) by halophyte Chenopodium Quinoa under hydroponic conditions and its further biodegradation through anaerobic digestion were evaluated. C. Quinoa was cultivated for a complete life cycle under different concentrations of SMT(0, 2 and 5 mg/L) and sodium chloride(0 and 15 g/L). C. Quinoa is able to uptake and partially degrade SMT. The higher the SMT concentration in the culture medium, the higher the SMT content in the plant tissue. SMT has different distribution patterns within the plant organs, and no SMT is found in the seeds.Dry crop residues containing SMT have a great potential to produce methane through anaerobic digestion and, in addition, SMT is further biodegraded. The highest specific methane yields are obtained using crop residues of the plants cultivated in the presence of salt and SMT with concentrations between 0 and 2 mg/L.

Biotransformation of Quinoa phenolic compounds with Monascus anka to enhance the antioxidant capacity and digestive enzyme inhibitory activity

引用

Food Bioscience 2022年第2期46卷 801-810页

作者： Pei Yang Kai Huang Yu Zhang Sen Li Hongwei Cao Hongdong Song Ying Zhang Xiao Guan School of Health Science and Engineering University of Shanghai for Science and TechnologyShanghaiPR China National Grain Industry(Urban Grain and Oil Security)Technology Innovation Center PR China

This research aims to change the phenolic fractions and the bioactivities of Quinoa by solid-state fermentation(SSF)with the edible fungus Monascus anka(M.anka).The contents of protein and fat increased in the fermented product,while the carbohydrate decreased.After 6-day fermentation with M.anka,the amount of phenolic compound reached the highest level.The majority of phenolic forms in fermented Quinoa were phenolic acids,mainly ferulic acid,protocatechuic acid and p-hydroxybenzoic acid.Ultrahigh-performance liquid chromatography-mass spectrometry(UHPLC-MS)results showed that SSF was an effective method to transform Quinoa phenolic compounds.Free fractions could be rapidly absorbed in the small intestine,suggesting that SSF with M.anka was a useful method to enhance bioavailable antioxidants.Antioxidant ability in vitro results showed that phenolic fractions from fermented Quinoa were greater than the unfermented Quinoa,and a significant cellular antioxidant activity(CAA)increment of 135%was obtained in the free phenolic fraction of fermented Quinoa.Moreover,α-amylase andα-glucosidase inhibition activities were enhanced with fermentation.Correlation matrix analysis revealed that most of the free phenolic compounds showed strong positive correlations with antioxidant activities and digestive enzyme activities.Consequently,fermentation with M.anka was a particularly promising method to enhance the bioactivity of Quinoa.

Due to good nutritional properties and potential health benefits,Quinoa has gained an increasing attention.The study aimed to analyze the effect of pressure cooking on the composition,antioxidant activity,antibacterial activity and bioavailability of phenolic compounds in four types of Quinoa,and to evaluate the correlation between phenolics and its biological activities by correlation analysis.The results showed that different varieties of Quinoa contained different phenolic components and their biological activities were different.Pressure cooking could significantly increase(PQuinoa,and decrease in vitro digestibility of protein.The antioxidant activity,antibacterial activity and bioavailability of Quinoa were also enhanced which were positively related with phenolic contents.HPLC analysis indicated that at least twelve phenolic compounds were found in Quinoa,and hyperoside,sinapic acid,rutin and ferulic acid occupied a majority of them.Correlation analysis suggested that hyperoside,quercetin,sinapic acid,ferulic acid and gallic acid made the key contribution to antioxidant and antibacterial activities of phenolic compounds of Quinoa.The results provided valuable information for Quinoa processing with phenolics as functional ingredient.
