Metabolic association of lipophilic pigments in the organs of soybean sprouts

Abstract

Ten soybean sprout varieties were examined for the evaluation of variations in lipophilic pigments, chlorophyll a and b, lutein, and β-carotene in seeds, whole sprouts, cotyledons, and hypocotyls germinated for 5 days in darkness at 20 o C with 80% humidity. Variations in lipophilic pigment contents caused a wide separation of each variety on a principal component analysis (PCA) scores plot, indicating that separation of varieties had wider lipophilic pigment responses from whole sprouts and cotyledons than those from seeds and hypocotyls. Hierarchical cluster analysis indicated that clusters of each organ from 10 varieties corresponded to PCA score plot results. Correlation analysis indicated that there were 4 positive correlations in both whole sprouts and cotyledons, but only 1 or none in hypocotyls and seeds. The responses of lipophilic pigments varied highly depending on variety and organ.

Physical and Antimicrobial Characterization of Self Assembled Silver Nanoparticle/Chitosan onto Low Density Polyethylene Film as Active Packaging Polymer

“…So most of the studies of antimicrobial food packaging have been done on LDPE polymer matrix. Some examples of antimicrobials which incorporated into LDPE are sorbate compound [6,7], imazalil [8], nisin [9], silver zeolite [10], and also natural extracts such as basil constituents [11], grapefruit seed extract [12], thymol and rosemary oleoresin [7] and clove extract [13]. Among all these, silver nanoparticles deserve special attention due to their unique properties, high thermal stability and long-term activity that discriminate from other antimicrobial additives.…”
