Pumpkin seeds are a major agricultural waste from the fresh-cut produce industry. The objective of this study was to investigate the drying behavior of untreated, whole pumpkin seeds in a fluidized bed dryer at 50–80 °C (2.87 m/s), with a view to producing a high-quality pumpkin powder from dried seeds. Seeds were dried at 50–80 °C to an average equilibrium moisture value of 0.035 to 0.006 g H2O/g DM (3.4 to 0.6% wb). Drying occurred in the falling rate period only and drying rate constants ranged from 0.0226 to 0.0900 1/min with corresponding diffusivity values for the first falling-rate period ranging from 4.68 to 18.63 × 10−10 m2/s. The activation energy (Ea)—for the first falling rate period was determined to be 43.9 kJ/mol. Of the nineteen thin layer models tested, the Alibas model could be successfully used as a general model to predict the Moisture Ratio (MR) data for all temperatures investigated. After drying, seeds were blended to produce powders, which were found to be high in fat, crude protein and fiber.

The subject of research – yogurt and pumpkin powder. The purpose of the study – to develop the technology of making yogurt with filler – pumpkin powder. Methods. Standard and practical research methods of dairy products were used. The qualitative indicators of the developed yogurt (sensorial indicators, viscosity, microbiological and toxicological indicators) during storage (15 days) were studied. The results of the study. Modern technologies of yogurt production include the use of various additives to improve the technological properties, as well as quality and texture characteristics. In this work, new technological solutions were developed in the formulations of yogurts without stabilizer with dietary fiber contained in pumpkin meal powder, the acceptability of new types of yogurts was evaluated. The dependence of a rheological indicator - the viscosity of the product depending on the amount of filler - in the storage process is analyzed. It was found that the largest increase in effective viscosity was observed in the sample with the introduction of pumpkin meal powder in the amount of 10 %, and the smallest – in the sample with the introduction of pumpkin meal powder in the amount of 5 %. This is due to the quantitative introduction of pumpkin meal powder into the formulation, which is a good sorbent that promotes a more even distribution of moisture between the particles of crushed plant material, which contributes to the formation of a denser clot. The influence of the filler – pumpkin meal powder on the microbiological parameters of yogurt during storage was determined. Studies of microbiological parameters of the control sample of yogurt classic and experimental samples with pumpkin meal powder during storage (15 days) indicate that the opportunistic and pathogenic microflora are within acceptable values. Toxicological studies have shown that safety indicators developed samples of yogurt with filler – pumpkin meal powder – meet the toxicological requirements for the type of product. Based on research, it is proven that yogurt with a natural filler – pumpkin meal powder retains high quality throughout the storage period. Scope of research results. The results of the research will be used to improve the technology of yogurt production at dairy plants.

The objective of this study was evaluation of the shelf life of reconstituted <italic>kheer</italic> packed in previously sterilized cups and stored at 10± 1°C for 3 days. During period of studies the samples were examined for sensory evaluation after the first, second and third day using five treatments T1 (Pumpkin flesh <italic>kheer</italic>), T2 (1 per cent pumpkin powder + 43 per cent skim milk powder), T3 (2 per cent pumpkin powder + 42 per cent skim milk powder), T4 (3 per cent pumpkin powder + 41 per cent skim milk powder) and T5 (4 per cent pumpkin powder + 40 per cent skim milk powder). Samples were studied for sensory properties <italic>viz</italic>. colour, flavour, body texture, appearance and overall acceptability. Statistical analysis for shelf life studies revealed that both the treatments and storage period had significant effect on sensory qualities of the product. The scores for colour, flavour, body and texture, appearance and overall acceptability of all <italic>kheer</italic> samples decreased with the advancement of storage period. The rate of decline in the flavour score of T3 was more as compared to all other treatments. The score for T3 was (7.12) on first day which dropped to (6.05) on third day. The rate of decrease of scores for body and texture was more in treatment T5 than T1, T2, T3 and T4. There was a statistically significant difference in the appearance of reconstituted <italic>kheer</italic> samples for all the treatments on the day of preparation. The difference between all treatments was non-significant on second and third day of storage. The overall acceptability for T1, T2, T3, T4 and T5 samples decreased with the progress of storage period.

The widespread introduction of non-traditional and local types of raw materials and the development of new types of products on their basis should be combined with the scientific substantiation of the composition and technology, which ensures the production of high-quality products, strengthening the control of biological and nutritional value, and the safety of new types of confectionery. One of the most important tasks faced by the confectionery industry is the development of new products in order to improve the structure of the range, save on scarce raw materials, reduce sugar content; creation of dietetic products, with a long shelf life. The use of raw materials of local and non-traditional species can contribute to solving this problem. The main source of vitamins, easily digestible carbohydrates, enzymes, fiber, pectin and minerals is fresh fruits and vegetables. Flour confectionery products, due to the high content of carbohydrates, fats and proteins, are high-calorie, well-digestible products with a pleasant taste and attractive appearance. Out of all the flour semi-finished products, the sponge cake is the bloated and softer. A well-baked cake is handy for processing; it has a smooth, thin crust; porous, elastic structure of the pulp – during compression is easily compressed, after removal of effort restores the old form. In the production of many foods, supplements that regulate the consistency and form the texture of food products are used. The structure of the sponge cake product is formed, mainly, at the stage of paste formation. The sponge cake is a poorly structured system with saturated air. The quality of the semi-finished product, above all, will depend on the quality of the resulting dough, which is substantially affected by the raw material. We have developed a recipe for a sponge dough, semi-finished product containing a pumpkin powder containing a significant amount of pectins, fiber, etc. In the structure of a sponge semi-finished product with pumpkin powder, thanks to the contents of polycarcids, which are merged with proteins bridges are formed. Osmotic swelling occurs as a result of the diffusion of water molecules inside the protein molecule, causing swelling of proteins. Microscopy of the structure of the biscuit semi-finished product was investigated in Slovakia (SPU).


The objectives of the study were to utilize the pumpkin powder in wheat based cookies. The pumpkins were properly dried to form powder. Standard methods were used to measure proximate parameters like Physical and Chemical. Fifteen (15) panelists conducted sensory tests of cookies from five formulations. The T3 sample of pumpkin cookies was founds the most preferred in colour, flavour, Taste, Appearance and overall sensory evaluation properties. Product T3 was predominantly Pale yellowish in colour. The Pumpkin cookies were more appealing and tasty than the plain cookies of control treatment
