electrical properties of fruits are accepted indicators for detecting fruit quality. electrical resistanceone reluctance can detect quality factors and are sensitive to variations in the concentration and stateof water. therefore, these properties can be associated with maturity, damage, overripe condition,decay or other quality factors. in most of previous research on electrical resistance and...

Background and Objectives: Thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. Also it is important to consider sensitive nature of food products during the thermal processing. Due to the nano-fluids' unique thermo–physical properties compared with the conventional f...

We have used a genetically tractable model system, the fruit fly Drosophila melanogaster to study the interdependence between sensory processing and associative processing on learning performance. We investigated the influence of variations in the physical and predictive properties of color stimuli in several different operant-conditioning procedures on the subsequent learning performance. Thes...

The physical properties exerted by dietary fibre are individual to the age and aiiatomy of the fruit or vegetable eaten. The physical properties will be determined by the chemistry of the constituent polysaccharides and lignins, In the plant these rnacromolecules arc systematically intermeshed for anatomical and physiological function. This intimate admixture is lost during digestion but the ma...

medium density fiberboard (mdf) was produced using moist depithed bagasse stored dry or wet. the duration of storage for either method varied between 0 to 4 months. two steaming temperatures of 175c and 185c were also used. mdf boards were produced in the laboratory and the common mechanical and physical properties were measured and compared. results showed that an increased steaming temperat...

Architectural properties of a fruit, such as its shape, vascular patterns, and skin morphology, play a significant role in determining the distributions of water, carbohydrates, and nutrients inside the fruit. Understanding the impact of these properties on fruit quality is difficult because they develop over time and are highly dependent on both genetic and environmental controls. We present a...

this study was carried out to investigate impacts of myrobalan rootstock and blackthorn interstem on fruit growth, physico-chemical features and bioactive compounds of two apricot cultivars (‘harcot’ and ‘roksana’) in 2010 and 2011. fruits of both cultivars on myrobalan and/or blackthorn grew with a classic double sigmoid curve from full bloom time to harvest. during growth and development peri...

Malic enzyme was isolated and purified from mature apple fruits (Malus sylvestris, Miller) by utilizing procedures probably applicable to other soluble enzymes in this and similar tissues.The physical properties of apple fruit malic enzyme are similar to those reported for malic enzyme from other plant and animal sources. It is specific for l-malate, TPN and requires a divalent cation for activ...

LUFFACHITIN obtained from the residue of the sponge-like dried fruit of Luffa aegyptiaca was developed as a weavable skin substitute in this study. A chemical analysis revealed that LUFFACHITIN was composed of a copolymer containing N-acetyl-glucosamine (~40%) as a major monomer with a filamentary structure as demonstrated by both optical and scanning electron microscopy. The pulp-like white re...
