The de-bittering effects of immersion in ethanol on white pomelo peel was investigated. suitable conditions for were found as sample: ratio 1/12 (g/mL), concentration 40°, time 4 hours, temperature 50°C, discharge and 3 rinsing times. Immersion with is highly effective 82.5% naringin bitterness removed pesticide residue reduced. However, the method also reduce content vitamin C sugar. Ethanol o...

A study was conducted to evaluate the quality of the leather from five different cultivars (Red Fleshed, Allahabad Safeda, Lucknow-49, Chittidar, Apple Colour of guava. Leather quality was also observed using three different recipes for its preparation. The study revealed that organoleptic quality (i.e. colour, flavour, taste, texture and overall acceptability) of leather decreased gradually wi...

ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3  in 2007 to 85 million  m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...

Rates of base-cation immobilization in the stem of basswood, beech, red oak, red maple, sugar maple and white ash were compared to identify the relative potential for impoverishing soils. Two natural stands in southern Quebec were studied. Allometric equations predicting stem nutrient content from stem diameter were developed. Between 20 and 25 trees per species were sampled for age and stem di...

Tea (Camellia sinensis) is a widely consumed beverage and recognised for its potential enhancing effect on human health due to its rich polyphenol content. While a number of studies have investigated the quantity and type of polyphenols present in different tea samples, no study has reported the potential effect of digestive enzymes on the availability of tea polyphenols for human absorption or...

Objective: There has been a growing interest in finding plants with biological active ingredients for medicinal application. Materials and Methods: Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. Results: The reddish pink flowers of A. officinalis have more antioxidant...

The study was conducted to investigate the potential of Parkia biglobosa fruit pulp as substrate for citric acid production by Aspergillus niger. Reducing sugar was estimated by 3,5-dinitrosalicylic acid and citric acid was estimated spectrophotometrically using pyridine-acetic anhydride methods. The studies revealed that production parameters (pH, inoculum size, substrate concentration, incuba...
