The Study of Quality and Safety Indicators of Mayonnaise on the Basis of Hemp Oil

Topicality. Sauces are an integral part of most dishes, which are prepared from a variety of products: meat, fish, seafood, vegetables. They give the dishes juiciness, add variety to the aesthetic appearance of the dish and complement their taste, increase calories, and nutritional value. The most common sauces are culinary sauces of the emulsion type, in particular, mayonnaise and its derivatives. Nowadays, the oil and fat industry produces a whole “line” of mayonnaise products with various additives that improve the taste, structure and increase the shelf life. The oil and fat industry is at a stage when its development can no longer be carried out by traditional methods, new approaches and solutions are needed. Trends in balanced and healthy diet are forcing producers to look for new approaches for the production of classic mayonnaise with high biological value and high quality characteristics. The problem of nutrition optimisation in terms of the content of essential nutrients, such as fatty acids, can be solved by introducing into the recipe some composition, such as an oil- fat base, vegetable oils are rich in polyunsaturated fatty acids ω-3 and ω-6. One of the promising areas of production of emulsion products, such as mayonnaise sauce, is the introduction of standard recipes for full or partial replacement of sunflower oil with hemp oil, in order to improve biological value, while maintaining high organoleptic, structural and mechanical properties and safety. Among the essential nutrients needed to maintain homeostasis of the human body are polyunsaturated fatty acids, the source of which is hemp oil. Hemp oil contains natural antioxidants, which gives a raised resistance to oxidation, despite the natural high content of ω-3 and ω-6 fatty acids. One of the ways to implement the innovative idea is the partial or complete replacement of the oil-fat fraction of the emulsion-type mayonnaise sauce with hemp oil in a mass fraction of introduction into the recipe (50%, 75%, and 100%). The aim of the study is to research the quality of mayonnaise sauce with partial or complete substitution of oil, and fat fraction for hemp oil, namely their organoleptic, physicochemical (effective viscosity, emulsion stability, acidity, acid and peroxide value) indicators, to investigate the fatty acid composition developed samples of mayonnaise sauce, based on hemp oil, and investigate the change in microbiological parameters during storage. This will expand the range of quality foods, enriched with essential nutrients. The following research methods are used in this article: standard methods of organoleptic profile analysis, structural-mechanical, standard methods of research of fatty acid composition, and methods of determining microbiological parameters. The results of this study are processed using modern computer programmes. Results. The expediency of using mayonnaise, based mayonnaise sauce technology, during the development of hemp oil sauce technology, has been theoretically and experimentally substantiated, and formulations of these mayonnaises have been elaborated. Based on the organoleptic analysis, it is determined that the use of hemp oil in the technology of mayonnaise sauce has a positive effect on its organoleptic characteristics. The study of the fatty acid composition shows that the optimal ratio of fatty acids of the groups ω-3: ω-6, as 1:4, has a sample of mayonnaise sauce (M2), containing 75% of hemp oil in its composition. The analysis of the fatty acid composition also confirms the functionality of all developed samples of mayonnaise. It is found that all elaborated samples of mayonnaise, based on hemp oil, fully comply with the normative indicators of structure (effective viscosity and stability of the emulsion), and quality indicators (pH, acid number, and peroxide value). It is investigated that the microbiological parameters of the control sample of mayonnaise and experimental samples with partial or complete replacement of the oil and fat fraction with hemp oil during storage (28 days) indicate that opportunistic and pathogenic microflora are within acceptable values. Conclusions and discussion. The studied quality indicators make it possible to substantiate the technology of mayonnaise sauce based on hemp oil with increased biological value.

According to the mentioned above, as well as economic feasibility of using automated systems for technological processes management, there is a need to elaborate a new mathematical and analytical approach to assessing and prognosticating changes in the quality of meat paste with various additives. Aim and research methods. The aim of this research is to elaborate a method for modeling the material system state, based on differential equations of kinetics of biochemical processes, assessment, and prognostication of food quality. Research methods. The method of mathematical and analytical evaluation of the paste products quality is grounded on modified mathematical models, differential equations, visualisation of research results in the form of 3D graphs, obtained by using symbolic computer mathematics. The quality of new meat paste products is compared with the quality of the paste, which is assumed to be relatively optimal according to the main organoleptic parameters of sensory quality assessment and control sample. The control sample of the paste is cooked according to the classical technology, and the recipe (GSTU 4424:2005). The prototype samples are cooked according to the innovative technology, which involves adding mechanically deboned poultry meat to the main raw material. Results. New results of analytical and experimental studies of the quality of meat paste products, cooked according to the classic recipe with the use of mechanically deboned poultry meat, are offered. The method for determining the coefficients, included in the mathematical model for assessing the meat paste products quality, their analytical relation with the optimization parameter, is elaborated. The expediency of using modern methods of symbolic computer mathematics for solving and analysing differential equations, presenting results in 3D graphs, is proved. The conducted research makes it possible to prognosticate the quality of food products, to control possible changes in their recipe while using various additives, to carry out elaborating new paste products. Conclusions and discussion. Based on the results of theoretical and experimental studies, a new mathematical model for estimating the quality of meat paste products in the form of the first-order differential equation, is offered. Its analogue is the equations, recommended for modeling the processes of biochemical kinetics. It is proved that the computer programme of mathematical and analytical research and prognostication the foodstuff quality (Goots et al., 2018) is universal. The offered mathematical model makes it possible to envision the quality of meat paste products, based on organoleptic evaluation. With its help, it becomes possible to determine the vector of possible changes in product quality and its optimisation, while elaborating the 3D graph. Mathematical and analytical assessment of the new paste products quality highlights that the partial replacement of the main meat raw by mechanically deboned poultry meat, and in pastes, made according to classical technology and the GSTU recipe (4424:2005), does not really reduce the parameters of organoleptic evaluation. In some cases, they are even higher than in the control paste samples, and very close to optimal ones. This new mathematical and analytical approach to assessing the paste products quality is promising in new culinary products elaboration in the restaurant business.

The Influence of the Parameters of the Subcritical Water Extraction Process on the Efficiency of Isoflavones Elicitation from Soy Meal

Topicality. Incidental products of soy processing (okara, meal, millcake) contain a large amount of protein, and, additionally, other valuable biologically active substances. Among them, isoflavones are of particular researchers’ interest. Subcritical water extraction is a promising method for elicitation biologically active substances from plant raw material. However, such a method of extracting isoflavones, and its rational parameters for soy meal, remain insufficiently investigated. Aim and methods. The aim of this work is to study the influence of parameters (temperature: 120...160°С, duration of extraction: 5...15 min, hydromodule: 1:15...25) of the extracting process of soy meal with subcritical water on the isoflavones content in the dry material of the extract. The empirical research method is applied, using the second-order orthogonal compositional outline for a fractional factor experiment. The samples of soy meal extract are obtained using the experimental setup, based on the high-pressure reactor “RHP-2-500”. The total isoflavones content in the dry extract material is defined in terms of gallic acid with absorption spectrophotometry method. Results. Based on the obtained results, the quadratic interpolation model is constructed. This model links the total isoflavones content in the dry extract material with the extraction parameters. The analysis of the constructed model makes it possible to establish rational measures of extraction parameters. Conclusions and discussion. In this study, the intensive growth of soflavones content in the dry extract with highing the temperature process, and a relatively small influence of the process duration on this indicator, were defined. The influence of the hydromodule is ambiguous. The lowest yield of isoflavones is noted at hydromodule ≈1:21,41. Its increase or decrease lead to the growth of isoflavones content in the extract. In this paper, for the first time, the existence of rational measures of parameters in the process of extracting isoflavones with subcritical water from soy meal is studied and established. The obtained results can be used in the elaboration of the technology for producing isoflavones enriched soy protein concentrate.
