After postharvest processing, it is essential to maintain quality of the seeds through storage over a long time. This review focused on the recently published research on different techniques that could be applied in postharvest processing and storage of Camellia oleifera seeds. The ferret studies support the hypotheses that cis-isomers are substantially more bioavailable then all-trans lycopene. [, found that tomato puree stored under light conditions, and duration of the light irradiation increased. A number of cis-isomers (predominantly 5-cis, 13-cis and 9-cis-) were detected in plasma, that are not present in the lycopene from pureé. to its content in minerals, flavonoids, and vitamins E and C, among others, but its high content in carotenoids, par-, ticularly lycopene, has also an especially relevant role, gives tomatoes their red colour. Download full-text PDF. Traditionally, the most important methods used are concentration (to a paste or Several research groups have suggested that cisisomers of lycopene are better absorbed than the all-trans form because of the shorter length of the cis-isomer, the greater solubility of cis-isomers in mixed micelles, and/or as a result of the lower tendency of cis-isomers to aggregate. As observed, the increment of treatment times in, -isomers of lycopene; (2) inactivation of, Response surfaces for lycopene content of tomato puree for, , concentrations of NaCl or citric acid, respectively, were kept, ].
