Sentence examples for bleaching activities from inspiring English sources

In addition to this, the hydroperoxidation and bleaching activities of LOX are highly correlated demonstrating that the bleaching might be ascribable to a cooxidative action by LOX, a free-radical-generating biocatalyst [ 5].

Enzymatic bleaching activity, under the conditions studied, is reported in Table 6, allowing a qualitative analysis of substrate specificity only.

It reveals the presence of some component with different chemistry but showing the same β-carotene bleaching activity.

β-carotene bleaching activity was determined by monitoring the absorbance decrease at 460 nm due to the disappearance of β-carotene (ε = 123.5 mM-1⋅ cm-1) [ 19].

Statistical analysis revealed that the three haplotypes are significantly different (P < 0.05) with respect to both linoleate hydroperoxidation and β-carotene bleaching activity.

Intermediate LOX activities were seen in the haplotype II cultivars, which showed linoleate hydroperoxidation activity of 2.59 ± 1.08 E.U./g of dry weight and β-carotene bleaching activity of 3.34 ± 0.65 × 10-2 E.U./g of dry weight.

As shown in Figure 6, the two activities followed roughly the same trend among cultivars, as high linoleate hydroperoxidation activity was always associated with high β-carotene bleaching activity.

Significant correlations (P<0.01, P<0.05) of IC50 were observed with total flavonoid contents and total phenolic contents in all antioxidant assays except DPPH scavenging activity and β-carotene bleaching activity.

One E.U. of β-carotene bleaching activity corresponded to the disappearance of 1 μmol β-carotene per min. All of the assays were carried out at pH 6.6 to simulate conditions that occur during pasta processing.

As shown in Table 2, the haplotype I cultivars showed the highest LOX activities, with mean values of 4.60 ± 2.38 E.U./g of dry weight for linoleate hydroperoxidation, and 5.76 ± 1.50 × 10-2 E.U./g of dry weight for β-carotene bleaching activity.

The ethyl acetate fraction showed good DPPH radical scavenging and superoxide anion scavenging activities whilst the crude methanol extract possessed excellent reducing power ability almost comparable to that of the standards BHA and ascorbic acid, and good β-carotene bleaching activity.
