BEF and sodium carboxylmethyl cellulose (a reference hydrocolloid) were added to WMF at 1.5 and 3% proportions, and breads were baked from the blends. Wheat flour (100%CWF) bread served as the control. Amylose level decreased significantly (p < 0.05), while water absorption capacity, peak and final viscosities of the blends increased with increasing proportion of BEF. The 100%CWF bread had better sensory qualities than WMF-BEF breads. Hence, BEF improved the physicochemical properties of WMF-BEF blend, but did not alter the sensory qualities of its gluten-free bread.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

Total phenol and total flavonoid of EOCC was 49.83±0.39mg GAE/g of extract and 352.82±3.45 µg QEC/g of extract respectively. Gas chromatography-mass spectrometry (GC-MS) analysis of its essential oil (EOCC) showed 25 peaks with myrcenyl acetate (9.703%), caryophyllene (8.997%), citronella (6.383%) been the most abundant. The in vitro anti-inflammatory assay using human red blood cell (HRBC) membrane stabilization shows that at 200µg/mL, the percentage inhibition of EOCC was significantly higher compared to diclofenac both for heat-induced and hypotonic induced haemolysis. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays showed a comparable and dose-dependent increase from 50 to 400 μg/mL in relation to vitamin C. Half maximal inhibitory concentration (IC50) of EOCC (73.16±12.89 μg/mL and 656.01±0.01 μmol Fe (II)/L) was remarkably higher compared to that of vitamin C (69.09±4.52 μg/mL and 246.79±0.01 μmol Fe (II)/L) both for DPPH and FRAP assays respectively.

After 6 weeks of cold storage in CA, eight types of fungi and molds were found that caused the mycotoxins patulin, deoxynivalenol, and zearalenone were found in the fruit of all cultivars. Fruits of the Ken’s Red cultivar were the most firm and puncture resistant, the darkest, and contained the most anthocyanins and the least L-ascorbic acid.

The results indicated that thermophilic digestion destroyed glycosidic bonds and fibrous crystal have a significant effect on the degradation of the corn stalks, while complex enzyme hydrolysis only slightly degraded fibrous crystal.
