Jivan C., Sala F., 2014. Relationship between tree nutritional status and apple quality. Hort. Sci. (Prague), 41: 1–9. Development of prediction models for the quality of apples is useful in guiding fruit tree nutrition and in optimising fruit management. The interrelationships between the leaf nutrient contents and some fruit quality indices were studied in five apple cultivars – Generos, Flor...

Soluble sugar and malic acid contents in mature fruits of 364 apple accessions were quantified using high-performance liquid chromatography (HPLC). Fructose and sucrose represented the major components of soluble sugars in cultivated fruits, whilst fructose and glucose were the major items of sugars in wild fruits. Wild fruits were significantly more acidic than cultivated fruits, whilst the av...

Kombucha is a fermented tea beverage which is traditionally prepared by fermenting sweetened black or green tea (Camellia sinensis L.) with symbiotic consortium of bacteria and yeasts (SCOBY). In this study, lemon balm (Melissa officinalis L.) was used as the only nitrogen source for kombucha fermentation. During the seven-day fermentation process, pH value, titratable acidity (TA), total pheno...

Acid drainage is most common problem or associated with almost all mines containing sulphide deposits and coal containing high pyrite. Acid drainage is caused when rain water and or seepage from rock formation interact with sulphur bearing minerals. It produces water of high acidity with higher metal concentration. Acid drainage is most susceptible to dissolve heavy metals particularly Iron, Zi...

Aegle marmelos Linn is a common plant used to treat many disease Conditions in Indian traditional systems of medicine. The present study was undertaken to findout a scientific validation for the efficacy of Aegle marmelos against gastric ulcer. Aqueous extract of Aegle marmelos leaves was prepared and used for investigation. A daily does of 1 gm/kg body weight of the extract administered orally...

Black currant berries contain many biochemical compounds with proven or potential human health benefits. We studied the content of total and single polyphenols, ascorbic acid, soluble sugars, and titratable acidity for two advanced selections and three cultivars of black currant at two distant locations in Sweden (south: 56°06'N; north: 65°21'N) over a 3 year period. Regression analyses reveale...

Objective: To evaluate the antiulcer activity of chloroform extract of Cedrus deodara and Pinus roxburghii wood (Cd C and Pr C, respectively). Methods: Cd C and Pr C at doses of 50 and 100 mg/kg were given orally to fasted rats and ulcers were induced by pyloric ligation and ethanol. Number of ulcer, ulcer score, ulcer index, percentage ulcer inhibition and tissue histology were measured in bot...

abstract   in this study, three groups of honey [natural honey; honey produced by the supplementary feeding of bees with saccharose syrup (ssh) and heat and acid (88 _ċ 2 h; 0.1% hcl) treated saccharose syrup honey (issh)] were produced and physicochemical (water content, ph, free acidity, ash, hmf, diastase activity, sucrose, protein and viscosity), microbiological and sensory properties of th...

Near Infrared spectrometry can be used for measuring the evolution of fruit quality traits. The main characteristics that can be measured are sugar content but also in some case acidity. In conjunction with IFV (institute of Vine and wine), Cemagref research centre and Pellenc SA company have conducted long term researches to get accurate measures of grape sugar and acidity in field conditions,...
