Item type:Publication, Retarding Changes of Postharvest Qualities of Sweet Basil (Ocimum basilicum Linn.) by Vapor-Phase Vinegar(2017-10-02); Fresh leaves of sweet basil (Ocimum basilicum) were exposed to ambient upland rice vinegar (URV) vapor containing 4% acetic acid (AA) for 0, 2, 4, 6, 8, or 10 min, before packing in polyethylene bags and storing at 12°C. This extended the postharvest storage life of sweet basil by retaining greenness, freshness, and antioxidants. The gas chromatography-mass spectrometry (GC-MS) results showed a number of other volatiles in URV vapor, including ethyl acetate, propane, pentanal, and acetic acid. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Antioxidant activities and heat stability of edible flowers of Telosma minor and Sesbania javanica(2018-01-02); ; Aqueous and ethanolic extracts from the edible flowers of Telosma minor (cowslip creeper), and Sesbania javanica (sesbania) were assessed for their their total phenolics, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity, and anti-lipid peroxidation ability. Aqueous extracts of cowslip creeper had the highest activities as a DPPH radical scavenger and as an inhibitor of lipid peroxidation. The value of the half-maximal effective concentration (EC<inf>50</inf>) for DPPH radical-scavenging of the aqueous cowslip creeper extract was 252.5 mg L<sup>−1</sup>, compared to the EC<inf>50</inf> values for the standards, ascorbic acid, and butylated hydroxytoluene (BHT), which were 2.26 and 21.80 mg L<sup>−1</sup>, respectively. For anti-lipid peroxidation, the IC<inf>50</inf> (the half-maximal inhibition concentration) value of the aqueous cowslip creeper extract was 1539.93 mg L<sup>−1</sup> while the IC<inf>50</inf> value of BHT was 683.5 mg L<sup>−1</sup>. The aqueous extract of cowslip creeper had the highest total phenolic concentration (991.3 mg gallic acid equivalents 100 g<sup>−1</sup> DW). The total phenolic content in cowslip creeper and sesbania flowers had high positive correlation with their antioxidant activities and anti-lipid peroxidation. The aqueous extract of sesbania flowers was the most heat stable antioxidant (100°C for 15 or 30 min), decreasing in total phenolic content but no changes in DPPH scavenging or in anti-lipid peroxidation activity.
