we sought to determine levels of oral bioaccessibility of hydroxymethylfurfural (hmf) from frequently consumed dried fruits in iran. fifty samples from frequently consumed types of dried fruits were analyzed for moisture, acidity and hmf content before and after in vitro digestion. besides, bioaccessibility of hmf in dried fruits using an in vitro gastrointestinal digestive model and hmf intake...

In this study, the effect of edible coat (carboxy methyl cellulose) before osmotic dehydration anddifferent drying methods on sensory and physical properties of dried apple (V. Golden delicious)rings was investigated. The coated and non-coated samples pretreated with 50% sucrose osmoticsolution and dried in freeze drier (-40 to -50°C, 0.026-0.017 mbar, 24 hr), vacuum drier (70°C, 200mbar, 8-10 ...

many parameters affect essential oil yield and chemical composition of aromatic plants. for obtaining the highest quantity and quality of essential oil, it is necessary to know the proper methods of drying and distillation. the aim of this research was to investigate the influence of drying and extraction methods on the yield and chemical composition of the essential oil of eucalyptus sargentii...

Background & Aims of the Study: The current study was designed to determine the quality of sediments in Karun in Ahvaz, Iran, according to aquatic pollution indices. Materials and Methods: The sediment samples were obtained from six river stations in summer and winter. The sediment samples were air-dried, sifted, homogenized, and stored in plastic bags, and the concentrations of metals were...

Abstract Duckweeds are promising potential sources for bioethanol production due to their high starch content and fast growth rate. We assessed the four species, Landoltia punctata, Lemna aequinoctialis, Spirodela polyrrhiza, Wolffia arrhiza, production. also optimized a possible procedure, which must include saccharification convert soluble sugars that can serve as substrate fermentation. were...

We study a one-dimensional elliptic problem with highly oscillatory random diffusion coefficient. We derive a homogenized solution and a so-called Gaussian corrector. We also prove a “pointwise” large deviation principle (LDP) for the full solution and approximate this LDP with a more tractable form. Applications to uncertainty quantification are considered.

Abstract The use of wood hemicelluloses, including galactoglucomannans (GGM) and glucuronoxylans (GX), in spray-dried microencapsulation bioactive compounds has not been reported. Our study aims to investigate the benefits GGM GX powders (sGGM sGX) along with effects homogenization techniques (magnetic stirring, ultrasonication, a combination UltraTurrax microfluidization) on physicochemical pr...

Background: Bacillus cereus is one of the important agents of the food-borne diseases worldwide. In the present study, the dried vegetable samples distributed in Tehran, Iran were evaluated in order to isolation, identification, and enumeration of B. cereus. Methods: A total of 140 samples containing open and packed dried vegetables were randomly purchased from different areas of Tehran, Iran ...
