This study evaluates the potential mechanism of action and bioactivity of black tea and black tea pomace for type 2 diabetes prevention via inhibition of carbohydrate hydrolyzing enzymes. Black tea leaves were extracted in hot water and black tea pomace was extracted in 70% acetone. The phenolic content of the water extract (WBT) and pomace acetone extracts (AOBT) were 5.77 and 8.9 mg/mL, respe...

In total, 170 carrot lines developed in Korea were screened for resistance to Meloidogyne incognita race 1 to select parental genetic resources useful for the development of nematode-resistant carrot cultivars. Using the gall index (GI), gall formation was examined on carrot roots inoculated with approximately 1,000 second-stage juveniles of the nematode 7 weeks after inoculation. Sixty-one car...

Carrot (Dacus carota var. sativus) is one of the top-ten most economically important vegetable crops produced worldwide, and the root-knot nematodes, Meloidogyne spp., are one of the most important pests in the carrot. In Korea, M. hapla and M. incognita are presumed to be the major root-knot nematodes distributing mostly in open carrot fields and greenhouses, respectively. In our study, curren...

Ascorbic acid, phenolic compounds and carotenoids were extracted from acerola (Malpighia emarginata DC.) by-products using gas-expanded liquids (GXLs) based on carbon dioxide expanded ethanol at 40 °C 7 MPa. The generated in the processing of acerola: bagasse (seed peel) non-pomace (from juice clarification step), studied separately. overall extraction yields obtained 3.8 12.9 g/100 g for non-p...

The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0.1 and 0.2 % (w/v) and tested for their antifungal activity ag...

Carrot seed oil is the source of the carotane sesquiterpenes carotol, daucol and beta-caryophyllene. These sesquiterpenic allelochemicals were evaluated against Alternaria alternata isolated from the surface of carrot seeds cultivar Perfekcja, a variety widely distributed in horticultural practise in Poland. Alternaria alternata is one of the most popular phytotoxic fungi infesting the carrot p...

Liquid-enriched powder (LOPP) and pulp-enriched (POPP) obtained from olive pomace were incorporated into yoghurt, not only, to increase its content in dietary fibre, hydroxytyrosol unsaturated fatty acids, but also understand the lipids-phenolics interaction by simultaneous incorporation of oil. POPP (2%) LOPP (1%) addition yoghurt allowed fulfilling condition being a “source fibre” provided 5 ...

Overview Each year the commercial carrot crop in Wisconsin suffers losses from alternaria leaf blight, cercospora leaf spot, and aster yellows. The first two are diseases caused by fungi (Alternaria dauci and Cercospora carotae). The third is a disease caused by the aster yellows phytoplasma, a parasitic bacterium of carrot phloem tissue and also of the aster leafhopper (Macrosteles quadrilinea...
