    (2020) Mykola Holovko, Tetyana Holovko, Vladyslav Prymenko, Anna Helikh, M. Zherebkin
    The possibility of using dietary selenium-protein additive "Neoselen" for enrichment of pastes based on mussels with organic selenium has been investigated. The formulation of the pastes involved the use of the soft body of the freshwater mmussels of the genus Anodonta. The influence of the introduction of different percentage of the additive "Neoselen" on the organoleptic properties of the developed pastes based on freshwater mussels was investigated. It is found that the addition of additive "Neoselen" even more than 5% does not impair the taste and color of the developed pastes. Moisture content, moisture retention, fat-holding capacity and active acidity of the developed pastes were investigated. The moisture-holding and fat-holding capacity of the developed paste is determined. The difference in the consistency of pastes based on freshwater mussels with different percentage of unpowered additives was investigated by determining the values of plastic viscosity and modulus of elasticity. The regularities of the influence of the additive "Neoselen" on the general chemical and mineral composition of pastes based on freshwater mussels have been established. It is established that the addition of 1%, 3% or 5% in the paste of additive "Neoselen" can enrich it by 7.8, 23.4 and 39 mkg of selenium, respectively. Studies have shown that in the composition of both the control and experimental samples of pastes in the amount of protein, minerals and water content. With the increase of the content of the additive "Neoselen" in the formulation of pastes, the content of protein and minerals increases. The complex of qualitative characteristics of the developed pastes is investigated. The regularities of the influence of the component composition on the organoleptic and physicochemical and functional-technological characteristics of the minced systems based on freshwater mussels and the additive "Neoselen" have been established. It is established that the optimal doses of the use of additive "Neoselen" in the formulation of pastes ranges from 3-5%.

    (2020) Zhenkun Cui, Tatiana Manoli, Tatiana Nikitchina, Haizhen Mo
    Currently, technologies that allow to preserve the native properties of raw materials in the finished product as much as possible thanks to the soft modes of technological processes deserve special attention. An important condition for obtaining healthy food products is the availability of a raw material base and technical means of extracting aquatic biological resources. The article shows that in China, a healthy lifestyle and the consumption of healthy food products are gaining popularity. China is a country that demonstrates absolute dominance in the production of shellfish, both aquaculture and in squid fishing. Despite this, there is a shortage of healthy food products in the domestic food market in China due to the uneven distribution of aquatic bioresources. The main type of processed shellfish are squids, which are traditionally very popular in China. In addition to frozen processed squid and other primary processed products, the main products from squid are minced squid, sliced squid and chopped squid, as well as various types of canned food. The article shows the high nutritional and biological value of squid, which is provided by high-grade proteins and essential polyunsaturated fatty acids. But when processing squids, a number of problems arise associated with the deterioration of organoleptic properties and a decrease in the biological value of the finished product. This article is a review and reveals a number of issues related to the features of the fractional composition of muscle tissue proteins of various raw materials. Also analyzed the changes in the physico-chemical parameters of proteins in a wide range of temperature effects. The article presents a promising type of technological processing, which allows to eliminate certain disadvantages of traditional technologies such as hard, dry consistency, weight loss of the finished product, as well as the loss of valuable extractive substances that provide organoleptic properties of food products. Such technologies with minimal impact on the technological properties of the finished product include SousVide technology. SousVide is a technology of low-temperature preparation of food products in a vacuum, which allows reliable monitoring of sensory performance and microbiological safety of products with strict observance of technological regulations.

    MATHEMATICAL DESIGN OF POLYCOMPONENT DRINKS WITH A BALANCED NUTRIENT COMPOSITION
    (2020) Liubov Telezhenko, Nadya Dzyuba, Antonina Іеgorova, Yevgeniia Balandina
    Based on the principles of food combinatorics using the methods of mathematical and computer simulation, formulations of polycomponent drinks based on dairy and vegetable raw materials were developed. The drinks were cow's milk, bananas, spinach and pumpkin were used as plant material and chia seeds were used as a source of unsaturated fatty acids. Using mathematical planning, the criterion equations for beverages characterizing the maximum content of basic nutrients have been formed. Computer simulation of beverage recipes was performed in Excel Solver in a Microsoft Excel spreadsheet, which formalized qualitative and quantitative indicators of balanced nutrients. In computer-aided design, optimization for each selected indicator was used by paired with the recommended nutrient content of FAO / WHO. Formulations of pumpkin, spinach and banana beverages were obtained in which the content of basic nutrients was 18,889 g, 17,664 g and 21,329 g per 100 g, respectively. Analysis of the chemical composition showed that the ratio of proteins: fats: carbohydrates is 1: 1.45: 3.03 for the drink "Pumpkin", 1: 1.34: 2.57 for the drink "Spinach" and 1: 1.5: 4 , 27 for the Banana drink. The ALST method determines the storage conditions of developed beverages, taking into account changes in sensory and microbiological parameters. Determination of optimal storage conditions by estimation of changes in organoleptic parameters makes it possible to state that the developed beverages will be competitive in the establishments of the restaurant industry of Ukraine. A study of changes in the microbiota of finished beverages within 4 hours at (4 ± 2) ° C in a closed glass container showed that, in the presence of conditionally pathogenic microorganisms, the beverages meet the current regulatory requirements. The integrated approach to the production of multicomponent beverages can be used by any market operator to produce not only beverages but also various food products.

    FEATURES OF ORGANOCHLORINE PESTICIDES RESIDUES ACCUMULATION IN MELLIFEROUS PLANTS, BEE POLLEN AND HONEY
    (2020) N. Kasianchuk, O. Berhilevych, I. Negay, L. Dimitrijevich, T. Marenkova
    Honey is natural product, which is produced by honeybees and due to contain of minerals, vitamins, simple sugars, organic acids, antioxidants and enzymes, it is considered as product with good nutritional and therapeutic properties. All beneficial characteristics of honey are reduced if it is contaminated with extraneous chemicals include pesticides. The purpose of this research was to study pesticides residues accumulation in the flowers of different types of melliferous plants, bee pollen and honey obtained from Odessa Region during 2015–2017 years. A total of 121 samples of flowers of melliferous plants and trees, 78 samples of bee pollen and 104 samples of honey were investigated with gas-liquid chromatography method. We found that all investigated samples were positive to such organochlorine pesticides as α, β, γ–isomers of hexachlorocyclohexane and dichlorodiphenyltrichloromethylmethane and its derivatives in different concentration. Our studies determined that high level of organochlorine pesticides was in samples of sunflower flowers whith average concentrations of α, β, γ–isomers of hexachlorocyclohexane 7.51±0.04 μg/kg, and DDT 6.98±0.02 μg/kg. Flowers of buckwheat and others field herbs (including as wild herbs as fodder crops) had even less concentration of these pesticides. Besides, the obtained results show that in the flowers of fruit trees (cherry, apple, pear, cherry, peach, cherry plum) had less concentration of studied pesticides in compere to forest trees (white acacia, linden). The results of bee pollen and honey samples examination have shown the same situation. The highest concentration of α, β, γ–isomers of hexachlorocyclohexane and dichlorodiphenyltrichloromethylmethane was in sample from sunflower origine with average consentration 3.52±0.05 and 3.77±0.03 μg/kg in bee pollen, 2.74±0.01 and 2.53±0.03μg/kg in honey respectively. However, the detected concentrations of pesticide residues in all samples were lower than the maxim admissibile limits, according to national and EU standards. Despite this, we suggest that regularly monitoring of pesticide residues in melliferous plants and apiculture products at national level need to grantee of quality and safety of honey and protection of consumers` health.

    CHOKEBERRY POWDER AS AN IMPROVER FOR PASTA
    (2020) Z. Koshak, A. Pokrashinskaya
    In the course of the study, the effect of dosages of black chokeberry powder on the quality of pasta made from flour with different gluten content was studied. The studies used normal-quality flour and low-gluten flour. To reduce the gluten content in wheat flour, it was mixed with potato starch. As a result of “dilution” of gluten with starch, its content decreased from 25 to 2.5 %. The resulting mixture was used to obtain pasta with the introduction of different amounts of black chokeberry powder. The effect of different doses of chokeberry powder on the gluten content of the obtained mixtures was determined by planning experiment 22 “with a star” in the StatGraphicsPlus package. It has been established that with increasing dosages of chokeberry powder, there is a decrease in gluten content and an increase in the content of pectin substances. In the finished pasta, the mechanical strength and the amount of dry matter transferred to the cooking water were determined. According to the data obtained, a chart has been developed to determine the dosage of chokeberry powder and the amount of starch introduced, at which the quality of pasta that meets the requirements of the standard is achieved. Thus, the introduction of 5.0 % aronia chokeberry powder with a gluten content in flour of about 18 % will make it possible to obtain products with a strength of 0.66 N and the amount of solids transferred to cooking water of less than 7.9 %. When using flour of normal quality, the addition of chokeberry powder in an amount of 5 % has a positive effect on the mechanical strength of pasta, increasing it by 20 % compared to the control sample. Other quality indicators, including cooking properties, are within the permissible norm. Production tests were conducted at Lidahleboproduct OJSC. Black chokeberry powder was added in an amount of 5%, pasta was made on Buhler production line with a capacity of up to 2000 kg per shift. According to the results of the tests, TU BY 500134647.012-2018 "Aronia" pasta and TI BY 500134647.001-2019 "Technological instruction for the production of pasta with Aronia" food additive were developed.
