Thesis structure: the thesis consists of introduction, four chapters, conclusions and recommendations, the list of cited works, annexes. The basic text contains 122 pages, 58 Figuraures, 43 tables, 12 annexes. The bibliography includes 255 references.

Field of study: 253.01 – Technology of plant origin products (Technology of catering products).

The purpose of the work: study of nutritional and sensory quality of Juglans regia L. walnut oilcake and identification of the optimal conditions for its processing and utilization in nutrition.

Objectives: evaluation of the main physic-chemical, microbiological and nutritional parameters of walnut oilcake, of the technological and bleaching treatments influence on nutritional and functional properties of walnut oilcake, oilcake valorisation as raw material for some confectionery.

Scientific novelty lies in the thorough and multidimensional analysis of the chemical composition, nutritional value and the changes that occur after technological treatments of walnut oilcake.

Important scientific problem solved is the establishment of the most important physicochemical, nutritional and technological properties of walnut oilcake and identification of the optimal and effective conditions of technological treatment and their use.

Theoretical significance. Scientific results were obtained, showing the possibility of directed modifications of walnut oilcake functional properties and chromatic parameters and improving consumer qualities of foods prepared with added oilcake.

The applicative value of the work consists in the establishment of optimal conditions for technological treatment of walnut oilcake, development of production technology and of the normative and technical documentation for confectionery prepared with added oilcake. It was obtained the patent „Method for the preparation of the walnut (Juglans regia L.) halva” (nr. 896).

Scientific results implementation. Confectionery technology has been tested and certified to the pastry and confectionery enterprise II „Galina Lisnic” from Edineţ.
