xanthomonas campestris was used for producing xanthan gum using date syrup, prepared from low quality dates, as a substrate. fermentation was carried out with date syrup and sucrose syrup at 28 ˚c and ph 6.8 in a rotary benmarin shaker (240 rpm). the effect of fermentation period (24, 48, 72, 96 and 120 h) on xanthan gum production was studied. the results showed that eps concentration increase...

Lactobacillus plantarum, as a potential lactic acid and protease producer, was used for biological extraction of chitin from shrimp shell. L. plantarum was grown in a batch culture containing shrimp shell powder and date syrup, incubated at 30 °C. The produced organic acids and proteases in L. plantarum culture were able to demineralize and deproteinize shrimp shell. Percentages of deproteiniza...

background: hydroxymethylfurfural (hmf) is a common maillard reaction product directly formed from dehydration of sugars under acidic conditions during heating and storage in carbohydrate rich foods. the aim of the present study was to detect and quantify the amount of hmf in date syrup by hplc method. in addition, the amount of hmf in date syrup produced by traditional and industrial methods w...

The potential use of date syrup, for the production of carotenoids by Rhodotorula glutinisin batch fermentation process, was investigated during 7 days. The results revealed that carbon (glucose or date syrup) and nitrogen sources [yeast extract, (NH4)2SO4 and NH4NO3] had a significant influence on biomass and carotenoid production. Maximum yield of total carotenoid production (7.94 mg/L) with ...

The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentationfor the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date syrupand sucrose solution (Bx. 10%) as fermentation media at 28°C. Re...

ultrafiltration (uf) was used for decolorization of an industrial iranian date syrup. experimental results were obtained by using two different concentrations of the date syrup (40 and 50 °brix) and two different membrane pore sizes (15-20 and 30-50 kda molecular weight cut-off values) under different trans-membrane pressures (tmp: 40, 70, 110 and 150 psi). the membrane with a pore size of 15-2...

abstract in this study the possibility of utilizing date syrup as a sugar replacer in soft ice-cream was investigated. for this purpose control sample was formulated based on iranian ice- cream standard. data syrup which produced from third grade kabkab dates, replaced sucrose in four levels (25, 50, 75 and 100%). physical properties including overrun, viscosity and freezing point (drawing temp...

OBJECTIVE Liquid medicines are easy to swallow. However, they may have disadvantages, such as a bad taste or refrigerated storage conditions. These disadvantages may be avoided by the use of oral solid medicines, such as powders or tablets. The aim of this study was to investigate the acceptability of and preference among four oral formulations in domiciliary infants and preschool children in T...
