Removal of S-Methylmethionine Sulfonium from Satsuma Mandarin Juice

The effect of rootstocks on sugars, acids, carotenoids, chlorophylls, and ethylene of Satsuma mandarin (Citrus unshiu)

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Title Studies on the Mechanisms of Detoxication of Histamine by Methylmethionine Sulfonium Chloride

Accumulation of carotenoids and expression of carotenoid biosynthetic genes during maturation in citrus fruit.

The relationship between carotenoid accumulation and the expression of carotenoid biosynthetic genes during fruit maturation was investigated in three citrus varieties, Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus sinensis Osbeck), and Lisbon lemon (Citrus limon Burm.f.). We cloned the cDNAs for phytoene synthase (CitPSY), phytoene desaturase (CitPDS), zeta-carotene (car) des...

The Effect of Rootstocks on the Peel Phenolic Compounds of Satsuma mandarin (Citrus unshiu)

The aim of this study was to determine total flavonoids and individually flavanone glycosides as well as antioxidant capacity in peel of Satsuma mandarin(Citrus unshiu) on different rootstocks.  On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of flavonoids.Total flavonoids content was measured using aluminum chloride colorimetric meth...

The role of carotenoid cleavage dioxygenases in the regulation of carotenoid profiles during maturation in citrus fruit.

To investigate the relationship between a carotenoid profile and gene expression for carotenoid cleavage dioxygenases, three citrus varieties that exhibit different 9-cis-violaxanthin levels in their juice sacs, Satsuma mandarin (Citrus unshiu Marc.; a variety accumulating a low level of 9-cis-violaxanthin), Valencia orange (Citrus sinensis Osbeck; variety accumulating a high level of 9-cis-vio...
