Purple carrots accumulate abundant cyanidin-based anthocyanins in taproots. UDP-glucose: sinapic acid glucosyltransferase (USAGT) can transfer the glucose moiety to the carboxyl group of sinapic acid thereby forming the ester bond between the carboxyl-C and the C1 of glucose (1-O-sinapoylglucose). 1-O-sinapoylglucose can serve as an acyl donor in acylation of anthocyanins and generate cyanidin ...

Ultraviolet B (UV-B) irradiation has been demonstrated to play a synergistic effect with wounding in enhancing the accumulation of phenolic antioxidants carrots. However, little is known about molecular mechanisms UV-B treatment on wounded In this study, carrots were exposed different doses light, then stored at 15 °C for 2 d. The results showed that content compounds 1 KJ m?2 UV-B–treated samp...

Pulsed electric fields application to whole carrots is a feasible strategy enhance carotenoids and phenolic bioaccessibility.

Multispectral imaging is increasingly being used for quality assessment of food items due to its non-invasive benefits. In this paper, we investigate the use of multispectral images of pre-fried carrots, to detect changes over a period of 14 days. The idea is to distinguish changes in quality from spectral images of visible and NIR bands. High dimensional feature vectors were formed from all po...

Many people want to eat healthier, but they often fail in these attempts. We report two field studies in an elementary school cafeteria that each demonstrate children eat more of a vegetable (carrots, broccoli) when we provide it first in isolation versus alongside other more preferred foods. We propose this healthy first approach succeeds by triggering one's inherent motivation to eat a single...

being healthy is important for living well and achieving longevity. in the business realm, furthermore, employers want healthy employees, as these workers tend to be more productive, have fewer rates of absenteeism, and use less of their health insurance resources. this article provides an overview of corporate “wellness” efforts in the american workplace and the concomitant challenges which em...

Studies on the bioavailability of As, of impacted vegetables; and As bioaccesibility in the edible parts of carrots (daucus carota), beets (beta vulgaris) and quinoa (chenopodium) growing in polluted soils thought “in vitro” gastrointestinal process; the As speciation both in the edible parts of vegetables and in their gastrointestinal extracts have been performed. Elemental analysis and As spe...

We monitored changes in phospholipid (PL), steryl lipid, and glycolipid classes, cell permeability, and ultrastructure in wound-stressed &sues (shreds and disks) of-carrots (Caucus car&~ L. ‘Apache’), stored UD to 10 davs at 10°C and 95% RH. Total PL rose 47% ten days after shreddini, with phosphatidylcholine decreasing and phosphatidic acid increasing in relative abundance. Acylated sterol gly...

Carrot is one of the most important horticultural crops, with an annual worldwide production exceeding 40 million tonnes. Carrots are sold either fresh intact or fresh-cut as minimally processed vegetables (MPV). In postharvest supply chain, physiological disorders, fungal decay, and their combinations reduce quality MPV carrots. carrots more susceptible to changes than due a higher loss protec...
