Abstract:

The object of research is the technology of enriching shortbread cookies with pumpkin flour. The problem of enriching shortbread cookies with pumpkin flour was solved. In the studies, different replacement of wheat flour with pumpkin flour was studied according to the following scheme: 0 %, 5 %, 10 %, 15 %, 20 %. The formation of strength, the ratio of the mass to the volume of the cake, its volume to the mass, the degree of swelling and sensory evaluation of the cookies were studied. As a result, it was established that the addition of pumpkin flour to the shortbread cookie recipe had a significant (р≤0.05) effect on its quality indicators. The strength of cookies and the ratio of its mass to volume increased with the addition of pumpkin flour. The degree of swelling and the ratio of the volume of cookies to mass decreased compared to the version without pumpkin flour. The use of pumpkin flour significantly changed the sensory indicators of cookie quality. The smell of cookies decreased from 9.0 to 3.7 points. The taste of cookies – from 9.0 to 3.0 points. Using it in the recipe reduces the volume of cookies, which reduces the degree of swelling and the ratio of its mass to volume. In addition, pumpkin flour has a specific smell and taste, which negatively affects the sensory evaluation of cookies. Therefore, the higher its content in the recipe, the worse the quality of the cookies. A distinctive feature of the obtained results is the use of 5 % pumpkin flour in the cookie technology. With this recipe, the strength is 1.45 kg, the degree of swelling is 1.70, the ratio of cookie mass to volume is 0.65, cookie volume to mass is 1.53. The color of the surface of the cookies is light brown, the color of the crumb is yellow, the pores are small, thin-walled, uniform, the consistency is crumbly. Smell is 8.3 points, taste – 9.0 points. The developed recommendations can be used by enterprises of low productivity for the production of shortbread cookies
