The flavanones naringenin and hesperetin exhibit estrogenic, anticarcinogenic and antioxidative properties. Orange juice and grapefruit juice contain high amounts of these compounds, and therefore their intake from the diet can be relatively high. No data are available regarding plasma concentrations or plasma kinetics of flavanones. The objectives of this study were to develop methods allowing...
Among the varieties of pineapples, honey pineapple is suitable to be processed as a probiotic beverage. The study aimed evaluate juice growth medium for Lactiplantibacillus plantarum subsp. Dad-13 strain. was fermented by adding starter culture L. plantarum Dad-13. fermentation time (0, 4, 8, 12, 16, 20, and 24 h) used variable. number cells increased significantly after (P < 0.05...
A polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique followed by sequencing of the 16S rDNA fragments eluted from the bands of interest on denaturing gradient gels was used to monitor changes in the bacterial microflora of two commercial kimchi, salted cabbage, and ingredient mix samples during 30 days of fermentation at 4°C and 10°C. Leuconostoc (Lc.) was th...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...
Imazalil ([1-(β-allyloxy-2,4-dichlorophenethyl)imidazole]) is a systemic chiral fungicide used in postharvest protection of citruses against fungi development for during storage and transportation. The chemical structure of imazalil shows an asymmetric carbon in the C7 position. These enantiomers may have different toxicity. A method for both chiral enantiomers extraction and determination in o...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
The aim of this study was to evaluate and compare potential different optical spectroscopic techniques for quality assessment apple juices. calibration partial least squares (PLS) regression models were developed optimized determination parameters juice non-destructively from the NIR spectra fruit or directly UV-VIS-NIR external validation performed using test sample set. Calibration based on c...
Present research investigation was aimed at morphological and biochemical assessment of Passiflora quadrangularis L. commonly known as giant granadilla locally called vegetable squash grown crop by the Adi tribe Arunachal Pradesh. Seven genotypes collected during survey were characterized for different traits. Results showed that average fruit weight 432.57g/fruit, with juice content 100.11 mL/...
A Preliminary Study of Yeast Strain Influence on Chemical and Sensory Characteristics of Apple Cider
During the fermentation of apple juice, yeast metabolism creates complex biosynthetic pathways which produce a range compounds responsible for organoleptic qualities cider. In this study, basic cider quality parameters were measured to investigate influence six strains on made from three varieties (‘Pink Lady’, ‘Sturmer’, and ‘Bulmer’s Norman’). Measurement pH, titratable acidity, total phenoli...
