Background Low-moisture foods, such as nuts, generally have been considered low risk for foodborne illness because they are consumed in a dry state. In low-moisture foods the water activity (available moisture) is too low to support microbial growth. For example, the water activity in tree nuts is generally less than 0.7. This may lead to the common misconception that low levels of pathogenic b...

This paper reports recent attempts for implementing non-destructive measuring of moisture content in wood based on computed tomography technology. The study focus on an image analysis method that has been already proposed and validated in the literature, but it has not been tested for measuring low moisture content variations below fibre saturation point. The computed tomography method was test...

objective anti-rh d igg is used for the prevention of anti-d antibody production in rh- individuals who have been exposed to rh+ red blood cells. the stability of igg preparations as a solution is low, with a shelf life of a year or more. formulation of anti-rh d igg as a lyophilized preparation would decrease its degradation rate and increases its shelf life. the objective of this study was to...

Moisture content of grain is one of the important parameters always considered when deciding the quality and price of grain, at the stage of harvesting, storage, processing and marketing. Grain having excess moisture content, if stored for long duration, will spoil due to insect/fungus infestation. Portable, field usable, and easy-to-use direct moisture (%) display Grain Moisture Meter is a nec...

Drying: moisture measurement at the end of drying is essential to follow up drying course and to decide whether it is achieved or not. On one hand, too long a drying course may have bad consequences for quality and food safety because of unexpected fermentations and mould growth. On the other hand, the next step in the process is storage. Also, drying to a too low moisture content can result in...

The spatial pattern of soil moisture varies at different scales due to evapo-transpiration and precipitation which are transformed by topography, soil texture, and vegetation. The mapping of soil moisture by remote sensing has several advantages over conventional field measurement techniques especially in the case of heterogeneous landscapes. However, validation of low resolution satellite soil...

Lotus-type porous aluminum with cylindrical pores oriented in one direction was fabricated by a casting method utilizing the decomposition of moisture in a vacuum. Hydrogen decomposed from moisture is utilized for cylindrical pores to grow during unidirectional solidification. However, pores are not formed in the case of a casting in hydrogen or argon atmosphere, because hydrogen or argon gas p...

Litter moisture contents vary greatly between and within practical poultry barns. The current experiment was designed to measure the effects of 8 different dietary characteristics on litter and excreta moisture content. Additionally, free water content and water activity of the excreta and litter were evaluated as additional quality measures. The dietary treatments consisted of nonstarch polysa...

in this study, response surface methodology (rsm) was used to optimize osmo-dehydration of orange slice. effect of osmotic solution temperature in the range of 30 to 60 °c, immersion time from 0 to 300 min and sucrose concentration from 35 to 65 brix degree on water loss, solid gain, moisture content, water loss to solid gain ratio and brix change were investigated by central composite design (...

background and objectives: kefiran (kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. the expansion of mixed systems can propose kefiran and polyvinyl alcohol (pvoh) as a new composite film. materials and methods: solutions of 20 gra...
