The major lipids ofthedogfish (Squalusacanthias) are the diacyl glyceryl ethers and triglycerides. These classes of compounds in the flesh (dorsal section) and liver were separated by thin-layer chromatography. The glyceryl ethers and/or fatty acids resulting from saponification of each of these fractions were analyzed by gas-liquid chromatography as their isopropylidene and methyl ester deriva...

In this study, the optimal conditions for spray drying of extract made from flesh and peel red pitaya were tested using central composite design (CCD). The response surface methodology was used to evaluate effect inlet air temperature (145 – 155°C) concentration maltodextrin (13-17% w/w) on physicochemical properties powder. regression models accurately predicted retention betacyanin (R2=0.94) ...

BACKGROUND In ancient times, plants were recognized for their medicinal properties. Later, the arrival of synthetic drugs pushed it to the backstage. However, from being merely used for food, plants are now been widely explored for their therapeutic value. The current study explores the potential of skin and flesh extracts from a hard-necked Rocambole variety of purple garlic in preventing card...

Some physical properties and chemical compositions of two cultivars (Semsouri and Shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. The physical properties investigated were the geometric mean diameter (GMD), specific gravity (SG), mean firmness (MF), rind, seed (%) and flesh (%). The chemical compositions were Brix, Titrable Acidity (T...

We investigated the effect of cultivation system (conventional or organic), cooking method, and flesh color on the contents of ascorbic acid (AA) and total phenolics (TPs), and on total antioxidant activity (Trolox equivalents, TE) in Solanum tuberosum (potato) tubers. The research material, consisting of 4 potato cultivars, was grown in experimental fields, using organic and conventional syste...

In our previous work we identified the presence of meso-zeaxanthin [(3R,3'S)-zeaxanthin] in trout flesh and skin (Nolan et al., 2014), but were not able to quantify this carotenoid with the method used at that time. In the present study, we developed a protocol that allows for the quantification of lutein and the three stereoisomers of zeaxanthin [(3R,3'R)-zeaxanthin, meso-zeaxanthin and (3S,3'...

Peach trees bear either white- or yellow-flesh fruit. We found that Japanese peach cultivars have two types of mutation in a carotenoid catabolic gene, CCD4: the insertion of a retrotransposon, and a frame shift in the microsatellite sequences of the first exon. CCD4 in yellow-flesh peaches was disrupted by these mutations.
