Abstract People suffering from the celiac disease have to apply a strict gluten-free diet because this is the only effective management. Unfortunately removal of gluten results in low quality for many cereal products. The aimof this study was to improve the technological and sensorial characteristics of gluten-free cookies (GFC) by using xanthan gum (XG). XG was added at 0-1-2-3 and 4% levels into gluten-free flour mixture prepared with corn starch, corn flour, rice starch and potato starch. Quality properties of GFC were compared with gluten-containing soft wheat flour cookies (SWFC). Incorporation of XG to GFC significantly affected various parameters such as; lightness, yellowness, hardness, fracturability and thickness of GFC were increased while redness, width and spread ratio were decreased. Moisture and water activity of GFC with no added XG were observed much lower than GFC with XG. Addition of XG to GFC also improved the sensorial scores significantly. The addition of xanthan gum was improved technological and sensorial quality characteristics of GFC and usage level of 3% XG resulted in these scores similar to that of a wheat SWFC.

Capsules of different formulations were prepared by using a hydrophilic polymer, xanthan gum and a filler Ludipress. Metformin hydrochloride, which is an anti-diabetic agent, was used as a model drug here with the aim to formulate sustained release capsules. In the first 6 formulations, metformin hydrochloride and xanthan gum were used in different ratio. Later, Ludipress was added to the formulations in a percentage of 8% to 41%. The total procedure was carried out by physical mixing of the ingredients and filling in capsule shells of size ‘1’. As metformin hydrochloride is a highly water soluble drug, the dissolution test was done in 250 ml distilled water in a thermal shaker (Memmert) with a shaking speed of 50 rpm at 370C &plusmn 0.50C for 6 hours. After the dissolution, the data were treated with different kinetic models. The results found from the graphs and data show that the formulations follow the Higuchian release pattern as they showed correlation coefficients greater than 0.99 and the sustaining effect of the formulations was very high when the xanthan gum was used in a very high ratio with the drug. It was also investigated that the Ludipress extended the sustaining effect of the formulation to some extent. But after a certain period, Ludipress did not show any significant effect as the pores made by the xanthan gum network were already blocked. It is found here that when the metformin hydrochloride and the xanthan gum ratio was 1:1, showed a high percentage of drug release, i.e. 91.80% of drug was released after 6 hours. But With a xanthan gum and metformin hydrochloride ratio of 6:1, a very slow release of the drug was obtained. Only 66.68% of the drug was released after 6 hours. The percent loading in this case was 14%. Again, when Ludipress was used in high ratio, it was found to retard the release rate more prominently.

Quality Features

Abstract In this paper it is stated, that a set of quality features of metal matrix composite castings differs from the same set for castings of classic materials, although some features are common for both of these material groups. These features (pertaining to a set of quality characteristics of composite castings) have been named as specific, they have not been determined yet and a description of material quality should be performed (according to the qualitology) on a principle of description of quality characteristics of this product. Therefore, this set of features has been determined. It was proposed to add the following characteristics to the set of specific features of composite castings quality: matrix material, reinforcement material, binding between components and porosity of the composite casting. In this set a sub-set of quality characteristics of composite castings was also determined.
