The present study characterized a genetically and phenotypically diverse collection of 27 purple two non-purple (one orange one yellow) carrot accessions for concentration root anthocyanins, phenolics, carotenoids, antioxidant capacity estimated by four different methods (ORAC, DPPH, ABTS, FRAP), in partially replicated experimental design comprising data from growing seasons (2018 2019). Broad significant (p < 0.0001) variation was found among the all traits. Acylated anthocyanins (AA)...

Garlic is a vegetable mainly agamically propagated, and it has been dispersed all around the world. cultivars have classified in different ecophysiological groups (EG) according to their bulbing requirements. The variability organosulfur composition (ACSOs), solids content (SC), pungency (PC) antiplatelet activity (IAA) correlation among these traits garlic clones belonging three EG was studied. We found for ACSOs, SC, PC IAA between also same EG. Cutivars III presented more than IV...

Fresh-cut produce have become widely popular, increasing vegetable consumption in many parts of the word. However, they are more perishable than unprocessed fresh vegetables, requiring cold storage to preserve their quality and palatability. In addition storage, UV radiation has been used experimentally try increase nutritional postharvest shelf life, revealing increased antioxidant levels some fruits including orange carrots. Carrot is one main whole fresh-cut vegetables worldwide. carrots,...

This work focused on the evaluation of nine clones fresh garlic and its aged product, black garlic, comparison their nutritional qualities, bioactive compounds, antioxidant activities, correlation among these traits. The results showed that moisture content material was reduced, while crude protein, fiber, ash, carbohydrate contents were considerably improved. Black had a higher total phenolic than four to times more activity. Hydroxycinnamic acid derivates main acids found in both garlic....

The organosulfur profile and the effect on oxidative stress vascular remodeling in fructose-fed rats (FFR) were evaluated Fuego INTA Morado garlic cultivars. Wistar fed either normal rat chow (control) or same diet plus 10% fructose drinking water. During last 6 weeks of a 12 week period corresponding diet, subgroup control FFR received an aqueous extract INTA. showed higher levels total thiosulfinates, allicin, pungency than increase systolic blood pressure, aortic NAD(P)H oxidase activity,...

ABSTRACT The aim of the present work was to evaluate application a physiological indicator as marker allicin content during postharvest storage at different temperatures. Sureño INTA garlic cultivar stored room temperature (20C ± 3) and cold (0C 0.5). Samples were taken periodically allicin, pyruvate analyzed sprout growth measured through visual index dormancy (VID). results showed that regardless temperature, VID changed significantly period assay. For conditions evaluated, highest...

In this study, the effects of two garlic-flavouring processes on quality parameters and organosulphur compound profile were investigated. The results showed that addition fresh garlic increased acidity peroxide values in all flavoured vegetable oils. Mono-, di-, trisulphides mainly present aromatised oils, while allicin, ajoene, vinyldithiins found macerated Analyses principal components demonstrate oils could be discriminated according to flavouring processes. experiments carried out study...
