Boidunyk R. Improvement of consumer properties of cakes on a waffle basis using alternative raw materials

The dissertation scientifically substantiates the expediency of using non-traditional types of raw materials for improving the consumer properties and preservation of waffle cakes with fatty fillings. The antioxidant efficacy of compounds of black cumin bunches, poppy seeds, pumpkin seeds, thistle seeds, lovage, herbs of buckwheat, rosemary and іvan-tea combined with a synergist on the fatty basis of filling of waffle cakes has been experimentally established. The new waffle cakes with fatty fillings were developed and offered for production: "Hrechanka", "Ivasyk-Telesyk", "Makovyi", "Lvivyanka" and "Osinnye Rondo" using alternative raw materials: buckwheat grass powder, іvan-tea, rosemary, lovage and blueberries; thistle snails, poppy seeds, pumpkin and black cumin; rye fermented malt, red lentil flour and kerob. It is proved that the used raw material provides the creation of new products with improved organoleptic properties, high nutritional and biological value. A comprehensive commodity evaluation of the quality of waffle cakes was carried out and the laws of changes in the indicators under the influence of processes occurring during storage, in particular, organoleptic, physico-chemical, microbiological, were proved. The possibility to extend the warranty period of storage of waffle cakes with fatty fillings up to 9 months with the stabilization of their consumer properties due to the use of non-traditional raw materials, vacuum packages of metallized polypropylene and packages of polyamides and polyethylene food with a modified gas environment, was experimentally established. The normative documentation (recipes and technological instructions) for the new waffle cakes of "Hrechanka", "Ivasyk-Telesyk", "Makovyi", "Lvivyanka" and "Osinnye Rondo" have been created and approved, their production implementation has been carried out. The development and introduction into the production of cakes on waffle basis with the use of the alternative raw materials has achieved a corresponding social and economic effect.
