The present investigation was undertaken in the Department of Processing and Food Engineering, College Agricultural Raichur to study different properties fresh coriander leafy vegetable like proximate composition, physical bio-chemical properties. It found that moisture content, carbohydrate, crude protein, fat, fiber ash content were 85.65, 4.26, 3.08, 0.3, 2.09 4.62 %, respectively. total fla...
Formation o f major prenylquinones and carotenoids was investigated by comparing the incorporation o f [14C]mevalonate into segments o f different age from green and etiolated leaves o f 22 °C-grown rye seedlings (Secale cereale L.) and from 32 °C-grown rye leaves which contained bleached and proplastid-like ribosome-deficient plastids, due to a heat-sensitivity o f 70S ribosome formation. The ...
Two major carotenoids of the stick insect were reinvestigated and shown to be /?,/?-caroten-2-ol and /?,/?-carotene-2,2'-diol and not isocryptoxanthin (/?,/?-caroten-4-ol) and isozeaxanthin (/?,/?-carotene-4,4'-diol). Both pigments are esterified with fatty acids. The identification is based on cochromatography with authentic 2-, 3and 4-isomers of the monoand dihydroxy pigment, mass spectra, an...
Iron and vitamin A deficiencies in childhood are public health problems in the developing world. Introduction of cereal-based complementary foods, that are often poor sources of both vitamin A and bioavailable iron, increases the risk of deficiency in young children. Alternative foods with higher levels of vitamin A and bioavailable iron could help alleviate these micronutrient deficiencies. Th...
BACKGROUND Palm kernel cake (PKC), a by-product of the palm oil industry is abundantly available in many tropical and subtropical countries. The product is known to contain high levels of phenolic compounds that may impede the deleterious effects of fungal mycotoxins. This study focused on the evaluation of PKC phenolics as a potential cytoprotective agent towards aflatoxin B1 (AFB1)-induced ce...
Protein is an essential nutrient for laying hens, playing a crucial role in egg production and supporting their overall health. An 8-week feeding trial was conducted on 120 Lohmann Brown hens (aged 38 weeks). The layers were assigned randomly to three groups housed cages (twenty replicates × two birds/cage). All fed corn–soybean meal basal diet (2750 kcal/kg metabolizable energy (ME) with 17.8%...
Bleaching Herbicides, Algae, Scenedesmus acutus, Carotenoids, Chlorophyll, Air/Nitrogen Gassing Over 24 and 48 hour cultivation periods the influence of SAN 9789 (norflurazon), EMD-IT 5914 (difunon) and fluridone on growth, photosynthetic oxygen evolution and pigment content of the green alga Scenedesmus acutus was determined. Four effects were observed: a) Both carotenoid and chlorophyll forma...
The pigment composition of Phaeocystis antarctica was monitored under various conditions of light, temperature, salinity, and iron. 19'-Hexanoyloxyfucoxanthin (Hex-fuco) always constituted the major light-harvesting pigment, with remarkably stable ratios of Hex-fuco-to-chl a under the various environmental conditions. Increased pigment-to-chl a ratios at low irradiance confirmed the light-harve...
PURPOSE The use of supplements as herbal and micronutrient natural health products with conventional health products has become increasingly popular. It has been reported that some herbal products can inhibit the activity of cytochrome P450-mediated metabolism and drug disposition. This study was designed to investigate a case report of a severe adverse event to determine the potential interact...
