products of lipid-protein composition for special purposes, that is, for nutrition of certain segments of populationchildren, athletes, pregnant women, the elderly, etc. The composition of such protein-fat mixtures (PFM) is consis-1. Introduction The newest and most promising direction in the oil and fat industry is development and production of combined TECHNOLOGY AND EQUIPMENT OF FOOD PRODUCTION
This work research object was fat systems interesterification biotechnology using the Lipozyme TL IM immobilized enzyme preparation. The problem of enzyme preparation activation by moistening with sodium bicarbonate aqueous solution with 7.4 ... 7.7 (3 % wt.) pH was solved in the work. The obtained results made it possible to minimize the interesterification process duration with high-quality product obtaining. The proposed enzyme preparation processing made it possible to reduce the duration of the biointeresterification process in a model fat mixture (palm stearin, coconut and soybean oils in a ratio of 1:1:1, respectively) to 3.5...3.7 hours. The product with high quality indicators, namely up to 0.26 mg KOH/g acid number, up to 0.60 mmol ½ O/kg peroxide number and 1.70 c.u. anisidine number, was obtained as a result. The obtained data can be explained by a fact that effective biocatalysis with lipolytic enzymes as the protein molecules requires the existence of two phases – lipid and water. This fact was provided by the activation parameters justified in the study. The obtained results feature was possibility of enzyme preparation activation, which is not provided under industrial conditions due to the threat of raw materials and finished products hydrolytic processes, which leads to the finished product quality deterioration. The research results made it possible to minimize hydrolytic processes in fat system during interesterification with simultaneous process efficiency increase. From a practical point of view, the discovered activation mechanism made it possible to adjust the enzyme preparation processing conditions in fat systems interesterification technology. The applied aspect of scientific result using was the possibility of improving the typical technological process of fat interesterification
The composition of "truffle" cream candies enriched with polyunsaturated fatty acids of ω-3 group, sesamol and tocopherols antioxidants and plant proteins in the digestible form was developed. Cream candies contain a protein-fat composite based on flax, sesame and sunflower seeds. These products can be used both in everyday and in special nutrition of athletes, soldiers, heavy manual workers, children and young people. It was determined that the oxidative stability of the model creamy candy mass increased with the concentration of protein-fat composite in it. The positive effect of the plant supplement on taste, aroma and "mouth-feeling" sensation parameters was proved by the obtained profilogram of organoleptic quality control parameters of experimental samples of candy masses with different content of protein-fat composite. Thus, it was established that the protein-fat composite in the composition of sweets improved its organoleptic and physicochemical quality control parameters, and also increased shelf life. The development allows to increase the consumer evaluation of the quality of "truffle" cream candies and, accordingly, their competitiveness.
The aim of the research is to determine the microbiological stability of a protein-fat mixture of flax and sesame seeds that allows to correct its storage life. A protein-fat mixture has a high content of irreplaceable amino acids ВСАА and polyunsaturated fatty acids of w-3group, so it may be positioned as a component of nutrition for athletes. Flax and sesame seeds, cultivated in Ukraine, were used as research materials. The product was created, based on comminuted flax and sesame seeds in ratio 1:1.
There were determined organoleptic (outlook, taste, smell, color) and physical-chemical (mass share of moisture, ash, protein, fat, acidic, peroxide, anisidine number) parameters of the product. There was determined the microbiological stability of the protein-fat mixture of the increased food value for athletes nutrition after 6 months. It has been proved, that as opposite to the control sample, the protein-fat mixture of the developed composition manifests its microbiological stability by the following parameters: content of mesophilic aerobic and facultative anaerobic microorganisms, molds, yeast, bacteria of the colon bacillus group and pathogenic microorganisms. The control sample that is comminuted flax seeds doesn’t manifest at the end of the storage term any correspondence of microbiological parameters by the content of mesophilic aerobic and facultative anaerobic microorganisms, molds, and bacteria of the colon bacillus group. This regularity is explained by the presence of lignans, sesamol and sesamoline, with preservative properties in the developed product. The obtained data may be used for reasoning recipes of products, based on the protein-fat mixture and correction of the food supplements ratio in them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
