Background and Objectives: Black mulberry is a juicy and dark purple to black fruit with a good balance of sweetness and tartness. This fruit is highly interested due to high quantities of anthocyanins. The bioactive compounds are often present in fruit tissues and should be released. The aim of this study was to extract bioactive compounds of black mulberries and assessment of heating process ...

Zirconium dispersed in aluminum-pillared montmorillonite was prepared as a catalyst for phenol hydroxylation. The effects of varying the Zr content on the catalyst's physicochemical character and activity were studied with XRD, BET surface area analysis, surface acidity measurements and scanning electron microscopy before investigating the performance for phenol conversion. The zirconia dispers...

The present experiment was conducted to detect quality and level of the adulteration in milk collected from Dharchuni, Atani and Khamar bazar of Muktagacha Upazilla. Organoleptic parameters used to monitor the status of milk samples were color, flavor, taste, texture; physical parameter used was specific gravity; chemical parameters used were acidity, fat content, protein content, lactose conte...

Samples of freshly harvested corn and remoistened corn were inoculated with Asphergillus flavus and stored for 4 weeks at about 27 C in air and three modified atmospheres. Aflatoxins and fat acidity were determined weekly. Corn stored in the modified atmospheres did not accumulate over 15 mug of total aflatoxins per kg. Corn from the high CO2 treatment (61.7 per cent CO2, 8.7 per cent O2, and...

1. It has been shown that there is a diurnal change in the H ion concentration in Bryophyllum calycinum corresponding approximately to the total acidity changes. The H ion concentration increases at night and decreases during the day. 2. Light is the main factor in causing the decrease in acidity, though it also occurs in the dark. but much more slowly. 3. External oxygen tension does not seem ...

Overall climatic effects on citrus fruit quality have been well-documented and are discussed by W. Reuther in his section on "Climate and Fruit Quality". These can be briefly summarized as higher sugar levels and lower acidity in humid areas with warm nights. Conversely, sugar levels tend to be lower and acidity higher in arid areas with cool nights. Such generalizations often vary when shorter...

background: high consumption of nonalcoholic beverages is one of the causes of dental erosion. annual consumption of beverages in iran is 48 lpcy (lit per capita per year) that is equal to 144 bottles per capita in year and is relatively a high rate. taking this into consideration, the present study was planned to determine the ph and fluoride content of beverages consumed in kerman, south east...

The influence of acidity on the growth of plants in water-culture has been studied by investigators with varying results. Many have reported a beneficial effect of moderate acidity; whereas others have succeeded in demonstrating equally good growth in solutions of widely different hydrogen-ion concentration. Citations to the literature can be found in a paper by the writer (5) dealing with the ...

introduction: fruits and vegetables have special importance as a very important part of the human food supply. and from the beginnings of life, man has used these products to supply a part of his food. nowadays, horticultural products are widely used in the diet. cherry is one of the deciduous trees in the temperate regions, which is potassium rich. use of oxalic acid significantly reduces fros...
