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

Cornlettes vegetable which is rich in dietary fibre has been studied for its potential in lowering the peak glycemic responses of biscuits and muffins. Cornlettes was processed into powder and formulated into four formulations of selected bakery products. The glycemic responses produced by portions of the biscuits and muffins containing 25 g available carbohydrate were measured in 11 healthy volunteers. The incremental area under curve (AUC) of control biscuits was greater (81 ± 11 mmol × min/l) than cornlettes powder (CP) added biscuit (63 ± 12 mmol × min/l). Likewise, the AUC of control muffins was higher (88 ± 13 mmol × min/l) than CP-added muffins (74 ± 12 mmol × min/l). Control biscuits had an intermediate GI value of 61 while CP-added biscuits had a low GI value of 46. Both control and CP-added muffins recorded intermediate GI values (58 and 57, respectively). It is concluded that CP can be incorporated in selected bakery products as a potential ingredient to help lower the peak rise of postprandial glycemic responses.展开更多

However, when using sugar replacers, product structure can be negatively altered. The effect on air cell development and microstructure with the use of Stevianna, or inulin, as sugar replacer was evaluated using muffins as a model food. The total replacement of sugar using Stevianna or inulin resulted in the development of non-uniform air cells leading to poor muffin microstructure. However, formulations involving partial sugar replacers gave similar air cell characteristics and hence microstructural characteristics, to that of the control sample. The results indicated that sugar is an important factor for the development of muffin microstructure and is difficult to replace completely.展开更多

The full calculation is carried out by recursion and tight-binding linear muffin tin orbital （TB-LMTO） methods. The amount of roughness is different at different atomic layers. The formalism is also applied to sharp interface, when interdiffusion of atoms is negligible. Our results of one monolayer transition metal agree with other reported results. A realistic rough interface is also modeled with three and four monolayers of transition metals, deposited on Au substrates.展开更多
