The Canned Vegetables Research in the Forensic Commodity Examination

The course of a forensic analysis of long-term storage food products (canned vegetables) has been reviewed. The significance of the stage of external inspection, examination of the label is shown. The expertise objects are finished products of the canning industry in factory package (vegetable marinades and first courses). The objects were examined for compliance with the appropriate GOST requirements and technical specifications for organoleptic characteristics, net weight, mass fraction of ingredients.As a result of determining the organoleptic properties of canned vegetables “Pickled beetroot” the presence of individual pieces with black firm beet tissue has been detected which indicates violation of technological patterns of production. The presence of a particle of an outside impurity has also been detected that is a particle of paint coating based on alkyd binder and containing calcium carbonate as a filler which is unacceptable. The deviation of the canned vegetables net contents from the nominal amount indicated on the label meets the requirements of the regulations. For individual cans from the sample provided for analysis the experts have found non-compliance with the technical specifications for the rate “Mass fraction of vegetables from the total mass of canned goods”.When examining the canned good “First courses. Borsch with fresh cabbage” it has been identified that the samples have various labels on the consumer containers which indicates the presence of samples from different shipments.

The main problems of grape storage are berry dehydration and rot. One of the solutions to reduce rot and preserve the quality of grapes during storage is the use of aerosol treatment with calcium content before storing. The aim of the study was to evaluate the effect of physiologically active substances based on calcium in various concentrations on the quality and organoleptic characteristics of table grape cvs. ‘Italia’ during long-term storage. The effectiveness of the studied systems of treatment was evaluated according to the content of sugars and titratable acids, the activity of the redox enzymes of polyphenol oxidase and peroxidase, weight loss of bunch and organoleptic properties. The greatest effectiveness established by using preparation of Master Green Ca, Brentax KCa, and Brentax Ca (in concentration 150g / 20l). Experimental treatments significantly decreased the weight loss of bunch (less than 4%), and preserved organoleptic properties of berry at a high level (8.2-8.9 points). Decrease in the activity of oxidative enzymes had a positive effect on the quality of table grapes and contributed to its better preservation. The data obtained make it possible to rationalize the system of long-term storage of grapes by using of aerosol treatment with calcium-based preparation.

В статье представлены результаты применения аэрозольных обработок кальций-содержащим препаратом «Мастер Грин Ca», дана оценка показателей качества винограда в процессе длительного хранении. Исследования проводились в течение 2020 г. в условиях Республики Крым на столовых сортах винограда: Италия, Ред Глоуб, Шоколадный и Молдова. Применение аэрозольных обработок способствовало изменению динамики относительного сахаронакопления сортов Молдова, Ред Глоуб и Италия, к концу хранения массовая концентрация сахаров превышала контрольные значения в диапазоне 3,9-17,6 %. Отмечено снижение активности полифенолоксидазы в опытных вариантах: у сорта Италия после 30 и 90 суток хранения - на 43 и 5 % соответственно, у сорта Ред Глоуб к концу хранения активность снизилась на 40,8 %. Установлено снижение значений естественной убыли массы винограда при применении аэрозольных обработок исследуемым препаратом: у сорта Ред Глоуб - на 44,6 %, у сорта Шоколадный - на 8,5 %, у сортов Молдова и Италия - на 24,4 %. Аэрозольные обработки оказали положительное влияние на органолептические показатели в период хранения, обеспечив гибкость гребня, сохранность естественного окраса, тургора ягод и гармоничности вкуса. Образцы винограда, обработанные препаратом «Мастер Грин Ca», были оценены на уровне 7,71 балла (Ред Глоуб) и 8,93 балла (Италия). The article presents the results of using aerosol treatments with calcium-containing preparation Master Green Ca, the assessment of grape quality indicators in the process of long-term storage is given. The studies were carried out during 2020 in the conditions of the Republic of Crimea on table grapevine cultivars: ‘Italia’, ‘Red Globe’, ‘Shokoladnyi’ and ‘Moldova’. Using of aerosol treatments contributed to changes in dynamics of relative sugar accumulation in the cultivars ‘Moldova’, ‘Red Globe’ and ‘Italia’; by the end of storage, the mass concentration of sugars exceeded the control values in the range of 3.9-17.6%. A decrease in the polyphenol oxidase activity in experimental variants was registered: for the cultivar ‘Italia’ after 30 and 90 days of storage - by 43 and 5%, respectively; for the cultivar ‘Red Globe’ by the end of storage the activity decreased by 40.8%. A decrease in the values of natural loss of grape weight when using aerosol treatments with the studied preparation was established for the cultivars: ‘Red Globe’ - by 44.6%, ‘Shokoladnyi’ - by 8.5%, ‘Moldova’ and ‘Italia’ - by 24.4%. Aerosol treatments had a positive effect on organoleptic characteristics during storage ensuring preservation of stem flexibility, natural color, turgor of berries and balanced flavor. Grape samples treated with Master Green Ca preparation were rated at the level of 7.71 points (‘Red Globe’) and 8.93 points (‘Italia’).

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
