Palmyrah neera (inflorescence sap) is susceptible to natural fermentation at ambient temperature within a few hours of extraction due enzymatic and microbial activity. Once fermented, becomes toddy which unsuitable as health drink or value-added product. Therefore, study was carried out investigate the influence different packing materials storage conditions on shelf life keep quality palmyrah ...
Abstract During postharvest life, strawberry fruit as a perishable commodity exhibiting short shelf life suffers from fungal decay that severely limits its marketability and nutritional value. Herein, we investigated the mechanisms activated by exogenous phytosulfokine ? (PSK?) application at 150 nM to delay senescence relieve in during storage 4 °C for 18 days. Our results showed higher extrac...
The Two cultivars of kiwi fruit, Hayward and Abbot, with the desirable quality were harvested on time from Valiabad, a region in Tonekabon (Mazanddaran Provicnce). Fruits were graded and packed in the wooden boxes, cartons and low density polyethylene (LDPE) films, the fruits were cold stored in a proper and constant conditions (T= ±0.5 & RH=90-95%) for a period of 6 months. Samples were taken ...
In the present study, the effect of addition of flaxseed mucilage on the physicochemical and sensorial properties of semi-fat (1.5% fat) set yoghurt was evaluated. Yoghurt samples were incorporated with flaxseed mucilage at the levels of 0.00, 0.10, 0.15, and 0.20% and analyzed periodically for pH value, titrable acidity, viscosity, consistency, water holding capacity, syneresis, colour paramet...
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...
The present investigation entitled, “Preparation of fresh and processed tomato salsa with herbs and to study its storage stability” was conducted with the objectives to standardize the formulation of tomato salsa, to compare sensory quality of fresh and processed tomato salsa and to study the nutritive characteristics of fresh and processed tomato salsa. Raw materials used in preparation of tom...
Delory & King (1943) published a comparative study of the hydrolysis by faecal alkaline phosphatase of a series of phosphoric esters and established a correlation between the pK values of their second phosphate dissociations, the optimum pH for the enzymic hydrolysis and the Michaelis constants of the esters. They showed that the more acid this phosphate dissociation, the more alkaline was the ...
The pomegranate fruit is one of the most important horticultural products due to the presence of polyphenolic, antioxidant and anti-fungal compounds. In the present study, morphological and phytochemical compounds diversity was investigated in eight Iranian commercial pomegranate cultivars. Fourteen morphological characters and 10 chemical compounds were measured. Based on PCA analysis the most...
