Quality characteristics of tomato fruit will be affected by a number preand post harvest factors. In this study, the effect of maturity stage on post harvest quality characteristics of tomato was investigated. Tomato fruits of the same farmers‟ variety were harvested at mature-green, medium ripe and full-ripe stages. After harvesting, tomato samples were sliced and homogenized in blender for pr...

Quantitative analysis of separated carboxylic acid fractions of 33 crude oils from the UK, Italy and California, showed that the carboxylic acid fraction is a major factor responsible for the acidity in these oils. It was apparent that biodegradation is the main process that produces high concentrations of carboxylic acids in these crude oils with the extent of biodegradation, as measured from ...

BACKGROUND Tropical peat swamp forests (TPSF) are globally significant carbon stores, sequestering carbon mainly as phenolic polymers and phenolic compounds (particularly as lignin and its derivatives) in peat layers, in plants, and in the acidic blackwaters. Previous studies show that TPSF plants have particularly high levels of phenolic compounds which inhibit the decomposition of organic mat...

Raspberry leaf blotch emaravirus (RLBV) has become established in many Serbian raspberry orchards as the most prevalent virus of raspberries country. The aim this study was to evaluate impact RLBV on red ?Willamette? variety. A trial conducted four located Western Serbia. Fruits from RLBVinfected and uninfected canes were analyzed for fruit size (fruit length, width, height, shape, weight), sol...

In this study, the drying characteristics and quality properties of electrical (ET) ultrasound (US) pre-treated kiwi fruit slices were investigated. Electrical pretreatments carried out on parameters 100 V- 40 sec. 35 kHz-30 min respectively. After pretreatments, dehydrated using a convective dryer at 50°C 1.5 m/s air flow rate. The effects these rate (the total phenolic content, vitamin C, pec...

Several years ago experiments by one of us pointed to a lack of correspondence between blood acidity and pulmonary ventilation, which seemed to contradict the generally accepted view that the acidity of the arterial blood controlled respiration. These experiments (1) led to the statement that “The conception that the hydrogen ion concentration of the arterial blood regulates respiration is anal...

In this study, retting was carried out by Aspergillus niger. The pH, galacturonic acid (GA), and total reducing sugar were determined; the end point was identified by the classic empirical processes and by the maximal GA content of the retting water. The process gave clear and resistent fibers, and the retting time was similar to that of current industrial processes with bacterial enzymes. Cont...

photosynthetic characteristics and induction of crassulacean acid metabolism (cam) by drought stress were investigated in sedum album, sedum stoloniferum and rosularia elymaitica from crassulaceae. titratable acidity, malate content, phosphoenolpyruvate carboxylase (pepc) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. results showed t...

The rational use of nutrients is of fundamental importance for obtaining high productivity of high nutritional quality. This work was developed with the aim of evaluating the quality of pepper fruit grown under different fertigation managements and different levels of nitrogen and potassium. The experimental design was of randomised blocks in a 3 x 6 factorial scheme with four replications. The...
