چکیده

today the nutritional value of the meals, including snacks has increased because of consumer demand for healthy food. so the aim of this study was to examine the effect of adding stabilized wheat germ on levels of 0, 3, 6, 9, 12 and 15% (based on flour weight) on the quantity and quality of the un-extruded snacks. in order to measure the color values the image processing technique and image j software was used. results clearly showed that addition of wheat germ reduced the moisture content and l* value examples of samples. while the hardness, a* and b* values, and vitamin e of the final product increased by adding wheat germ. in addition evaluation of taste, tenderness, color and texture of the samples showed, the sample containing 9% wheat germ had the highest score of overall acceptability. finally it can be concluded that processed wheat germ with saturated steam up to 9% increased the nutritional value, and could also maintain technological and sensory characteristics of snacks to offer to the market as a healthy product.
