Effects of Interesterified Vegetable Oils and Sugar Beet Fibre on the Quality of Turkish-Type Salami
(Wiley, 2005) Javidipour, I; Vural, H; Özbas, ÖÖ; Tekin, A
Turkish-type salami is an emulsion type product that is only shelf stable at chilling temperature. The use of three interesterified vegetable oils (IVOs) prepared from either palm, cottonseed or olive oil (IPO, ICO and IOO, respectively) together with 2% sugar beet fibre (SBF) (<425 mum) was studied in the production of Turkish-type salami. These compounds were used to modify the fatty acid composition and increase the dietary fibre content of the traditional product. Beef fat (10%) was replaced by one of the IVOs at either 60 or 100%. The addition of SBF significantly increased (P < 0.05) the total dietary fibre content and water-holding capacity of salamis. Incorporation of IVOs improved the nutritional content of the product because it altered the fatty acid composition. It was found that total or partial replacement of beef fat by IVOs, as well as the presence of 2% SBF, did not lead to significant changes in appearance, colour, texture, flavour or sensory score. The use of IVO and SBF as fat substitutes could be used to obtain a low fat product with high dietary fibre and a modified fatty acid composition.
Viscosity Estimation of Vegetable Oils Based on Their Fatty Acid Composition
(Food Nutrition Press inc, 2002) Boyaci, IH; Tekin, A; Çizmeci, M; Javidipour, I
Experimentally determined viscosities of cottonseed, olive, hazelnut, corn, sunflower, canola and soybean oils were used in the development of an equation for simple and rapid viscosity estimation based on the fatty acid composition. The parameters A and B in the Andrade Equation were derived from the constants determined from each fatty acid using a computer program. The obtained equation was tested in the estimation of the viscosities of vegetable oils and their binary mixtures. Predicted and experimental viscosity values were then compared and average absolute deviations (AAD) calculated as 1.78% for vegetable oils and 3.48% for their mixtures. Due to the reasonable accuracy, this method could be applied to the common vegetable oils and their blends. This study also represents a model for their viscosity prediction of the oils having different fatty acid compositions.
