Muffins were prepared with FSH at different levels and batter flow properties were studied. The muffin batter viscosity increased from 32,500 to 38,000 cps when the FSH content increased from 0 to 15%. While the muffin vol-umes increased upto 10% addition of FSH and further FSH increase did not result beneficially. Supplementation with FSH resulted in softer crumb texture indicated by the hardness which decreases in hardness 4.20 to 3.19 N. Inclusion of FSH addition in muffins found acceptance by panelists with a rating better than the control. The optimal level of incorporation of FSH flour, based on sensory quality in muffins was found to be 10% and use of Polysorbate-60 at 0.5% level in these muffins further improved the overall quality characteristics. These muffins had double the amount of dietary fiber.展开更多

This study aimed to give results related to the existence of antioxidant phenols in agricultural waste of selected Northern Thai rice varieties. The antioxidant activities, contents of total flavonoids and phenolic compounds in the ethanolic rice husk extract were evaluated. The highest antioxidant activities were found in the variety PES1CMU, with 2,2’-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid and 2,2-diphenyl-1-picrylhydrazyl as 679.66 and 4.16 mmol/(L·g) trolox equivalent, respectively, ferric reducing antioxidant power as 0.87 mmol/(L·g) Fe2+, total phenolic content as 29.90 mmol/(L·g) gallic acid and total flavonoid content as 12.16 mg/g catechin equivalent. Polyphenol compounds were identified mainly by standard polyphenols using the liquid chromatography mass spectrometry, with the highest contents of phytic acid, o-coumaric acid, naringin and kaempferol. The non-glutenous and wetland ecotypes of rice husk samples were the richest in antioxidant activities and polyphenol contents characterized by using principal component analysis. The glutenous rice husk contained higher antioxidant activities than the rest. Interestingly, quercetin is a significant phenolic compound that positively correlated with the overall antioxidant activities of rice husk. This finding will be relevant for future application of rice husk antioxidant components in the production of functional ingredients as well as for the food and pharmaceutical industries.展开更多

Homogenous samples of poppy seeds and products containing poppy seeds were digested by means of microwave digestion system by using of nitric acid and hydrogen peroxide as reagents. The measurements were carried out using an atomic absorption spectrometer with Zeeman background correction. Detection limit was 0.003 mg/kg. A total of 208 samples of poppy seeds （from years 2004-2009） and 17 samples of semi-finished and baked goods were analysed. The average content was 0.64 mg/kg （median 0.64 mg/kg） for poppy seeds and 0.079 mg/kg （median 0.069 mg/kg） for semi-finished and baked goods. The relative standard deviation was lower than 5% for all measurements.展开更多
