And Storage

The effect of the hygienic status of raw materials on biogenic amine production during ripening and storage (at 4 and 15°C) of fermented sausages was studied. Two portions of fresh lean and back fat pork were stored for 5 days at −20°C (treatment A) and at 4°C (treatment B), respectively. Raw materials of treatment A maintained their hygienic quality high and low amine content. Raw materials of treatment B showed from 1 to 3 log (CFU/g) higher microbial counts and a biogenic amine index near 50 mg/kg, indicating poorer hygienic quality. The quality of raw materials influenced the composition and the concentration of biogenic amines produced during the ripening sausages. Sausages of treatment A (A-sausages) showed a large accumulation of tyramine (up to 100 mg/kg dm) followed by putrescine and cadaverine (<15 mg/kg). In contrast, B-sausages resulted in earlier and much greater amine production, and cadaverine, tyramine, and putrescine levels were 50-, 2.6-, and 6.5-fold higher than those of A-sausages. Other biogenic amines, such as octopamine, tryptamine, phenylethylamine, and histamine were also produced in B-sausages. The higher proteolysis and the lower pH of B-sausages might have favored the decarboxylase activity of microorganisms. Biogenic amine contents of sausages during storage depended on the raw materials used and storage temperature. No significant modification on the amine contents was observed during the storage of A-sausages at either temperature. Greater changes occurred in B-sausages stored at 15°C than in those stored at 4°C. Higher temperatures favored proteolytic and decarboxylase reactions, resulting in increased amine concentrations after storage.

The effectiveness of an amine-negative starter culture (Lactobacillus sakei CTC494) in the reduction of biogenic amine production during the ripening of fermented sausages was examined. Four batches were manufactured in parallel:spontaneously fermented and starter-mediated sausages were manufactured from two lots of raw materials of different hygienic quality. Besides the biogenic amine contents, changes in the microbial counts, nitrogenous fractions, pH, and water content were measured at several sampling points during the ripening process. In sausages manufactured from good quality meat, the starter strain of L. sakei reduced and even inhibited biogenic amine accumulation during sausage fermentation, the end products showing extremely low biogenic amine contents (tyramine levels less than 15 mg/kg of dry matter and putrescine and cadaverine levels less than 5 mg/kg of dry matter). Nevertheless, starter-mediated sausages made from poorer-quality raw materials showed much higher amine contents (308, 223, and 36 mg/kg of dry matter of cadaverine, tyramine, and putrescine, respectively), which were only slightly lower than those of the spontaneously fermented sausages made from the same raw materials. The relatively high bacterial numbers of raw materials of poorer-hygienic quality diminished the beneficial effect of the starter strain. Therefore, the effectiveness of the starter was strongly dependent on the hygienic quality of the raw materials used.

The aim of this study was to determine the hygienic quality of the pheasants reared for high-quality meat production by the biogenic amine concentrations in their meat. The content of biogenic amines was measured in the meat of sixty male pheasants killed by pithing and stored uneviscerated for 21 days under different storage temperatures (0 °C, 7 °C and 15 °C). The samples of breast and thigh muscles of pheasant were tested at weekly intervals. Biogenic amines were analysed by reverse phase liquid chromatography and detected by tandem mass spectrometry. Concentrations of biogenic amines (except spermin and spermidin) in thigh muscle were higher than in breast muscle. Highly significant difference (P < 0.01) was found in tyramine (5.80 mg/kg and 1.38 mg/kg for thigh and breast muscle, respectively), cadaverine (40.80 mg/kg and 14.43 mg/kg for thigh and breast muscle, respectively), putrescine (13.42 mg/kg and 3.16 mg/kg for thigh and breast muscle, respectively) and histamine (5.51 mg/kg and 1.70 mg/kg for thigh and breast muscle, respectively) concentrations after 21 days of storage at 15 °C. This study provides information on the dynamics of biogenic amine formation in pheasant meat during 21 days of storage at different temperatures. Based on our results, we can recommend storing pithed uneviscerated pheasants at 0–7°C for up to 21 days, or at 15 °C for up to 7 days. Concentrations of biogenic amines gained in our study can be helpful in evaluating freshness and hygienic quality of the pheasant game meat.

Hygienic quality of game meat depends on many factors during and after hunting. Freshness of meat is connected with the concentration of biogenic amines which is related to meat spoilage. The aim of this study was to assess changes in concentration of biogenic amines in raw meat of wild boar (n = 20, mean age 1–2 years) during storage at different temperatures. Carcases of wild boars hunted in winter 2012 in hunting districts of south Moravia were stored unskinned during 21 days at various temperatures (0, 7 and 15 °C). Concentrations of biogenic amines (putrescine, cadaverine, tyramine, tryptamine, phenylethylamine, histamine, spermine and spermidine) were determined in the shoulder and leg muscles by high-performance liquid chromatography in combination with triple quadrupole tandem mass spectrometry. Good hygienic quality was maintained when wild boar carcasses were stored for a maximum of 14 days at 0 °C (content of biogenic amines in 3 meat samples exceed the limit of 5 mg/kg on day 21 of storage) or a maximum of 7 days at 7 °C (content of biogenic amines in 4 meat samples exceed the limit of 5 mg/kg on day 14 of storage). The temperature of 15 °C should be considered as unsuitable storage temperature if good hygienic quality of game meat during storage is to be guaranteed (content of biogenic amines in 2 meat samples exceed the limit of 5 mg/kg already on day 7 of storage). The study brings new information about the biogenic amine content and its changes in wild boar meat during the storage period of 21 days.

Rasbora lateristriata is one Indonesian freshwater fish consumed by society as a source of animal protein. Like fish in general, rasbora is considered as perishable food, so it is necessary to apply a proper storage technique, one of which is cold storage. The purpose of this study was to determine the proper storage temperature of the rasbora in the storage of freezer, chiller and ice. The raw materials used was rasbora in size of 2 grams/fish. The Wader was caught then pondered (2,1 kg). Rasbora was split into three different storages those were freezer (-20°C), chiller (4°C), and ice (10°C). The study design used a completely randomized design with storage temperature factors and the duration of storage with three treatments and three replications. Observations were made on days 0, 5, 10, 15, 20, 25, and 30 include TPC test, TVB, pH and organoleptic. The results showed that treatment of freezer, chiller, and ice storage were able to inhibit decay until the 40th day, 13th day, and day 2, repectivelly. Thus, the freezer storage (-20° C) provides more effective in inhibiting decay by TPC, TVB, pH and organoleptic.

The manufacturing process, the source (raw materials), and primary packaging materials dictate requirements for the quality of ethyl alcohol used in the pharmaceutical industry.The aim of the paper was to analyse how the quality of ethyl alcohol used as a component of medicinal products depends on the starting materials, production method and technology, intended use, and the choice of the primary packaging. The paper analyses available information on ethyl alcohol quality and summarises data on potential impurities associated with the ethyl alcohol production technology and the starting materials used. It was established that Russian manufacturers mainly use grain crops (wheat and rye), as well as molasses—a by-product of the sugar industry, as raw materials. The paper addresses the process of improving the quality standards for ethyl alcohol from a historical perspective. A comparative study of the requirements of the Russian and the world’s leading pharmacopoeias for the pharmaceutical substance—ethyl alcohol 95%, 96% demonstrated the need to include identification by IR-spectrometry and impurity control by UV absorbance into the respective monograph of the State Pharmacopoeia of the Russian Federation. The authors formulated requirements for the choice of packaging material for ethyl alcohol, which will not affect its quality during transportation and storage.

Целью исследования являлось изучение влияния свойств орехового сырья на направление и скорость процессов миграции жиров в глазированных конфетах с пралиновыми корпусами. Исследование процессов миграции жиров между корпусом и глазурью в процессе хранения необходимо для прогнозирования сохранности и предотвращения органо-лептической порчи в результате осветления или умягчения глазури, а также «поседения» поверхности изделий. Предложен подход прогнозирования скорости процессов миграции жиров при хранении конфет с корпусами, изготовленными на основе орехового сырья, с использованием удельной скорости миграции жиров. Исследованы процессы миграции жиров в модельных образцах конфет с пралиновыми корпусами на основе арахиса, фундука, кешью, миндаля, покрытых глазурью с использованием заменителя масла какао лауринового типа при температуре хранения 18 °С. Показано, что удельная скорость миграции олеиновой кислоты на поверхность модельных образцов глазированных конфет с корпусами на основе арахиса превышает скорость миграции в конфетах с корпусами на основе кешью приблизительно в 20 раз. Полученные закономерности позволяют установить дополнительные требования к качеству используемого жирового сырья для уменьшения скорости миграции жиров. The aim of the work - the investigation of the influence of nut raw material properties on the direction and speed of fat migration processes in glazed sweets with praline cases. The study of fat migration processes between the body and the glaze during storage is necessary to predict the safety and prevent organoleptic spoilage as a result of lightening or softening of the glaze, as well as «graying» of the surface of the products. An approach to predicting the rate of fat migration processes during the storage of sweets with cases made on the basis of nut raw materials using the specific rate of fat migration is proposed. The processes of fat migration in model samples of sweets with praline cases based on peanuts, hazelnuts, cashews, almonds, glazed with glaze, with the use of a lauric-type cocoa butter substitute were investigated at a storage temperature of 18 °C. It is shown that the specific rate of migration of oleic acid to the surface of model samples of glazed sweets with peanut-based cases exceeds the migration rate in sweets with cashew-based cases by approximately 20 times. The obtained regularities allow us to establish additional requirements for the quality of the fat raw materials used to reduce the rate of fat migration.

Многокомпонентный и сложный состав глазированных конфет с корпусами пралине и типа пралине обуславливает протекание процессов миграции и окислительной порчи жиров, которые приводят к ухудшению органолептических показателей. Целью исследования являлось изучение влияния свойств орехового сырья и температуры хранения на скорость окислительных процессов. Увеличение массовой доли линолевой кислоты от 0,9 % до 6,2 % в результате миграции жиров корпуса в глазурь обусловило повышение скорости окислительных процессов, что подтверждено исследованиями показателей окислительной порчи. После двух месяцев хранения при 18 °С перекисное число жировой фракции корпусов конфет, изготовленных с использованием орехов, увеличилось от 0,4-0,5 ммоль акт. кисл./кг до 0,4-1,2 ммоль акт. кисл./кг. В жировой фракции конфет, изготовленных на основе арахиса, в процессе хранения при 18 °С перекисное число увеличилось до 0,9-1,6 ммоль акт. кисл./кг. При этом индукционный период жировой фракции корпусов таких конфет уменьшился от 23,5 ч до 13,6 ч, то есть в 1,7 раза. Повышение температуры до 27 °С привело к уменьшению индукционного периода до 8,4 ч, то есть в 2,8 раза. Для корпусов конфет, изготовленных на основе орехов, индукционный период после 2 мес хранения конфет при температуре 18 °С уменьшился в 1,2 раза. Использование орехового сырья позволяет увеличить сохранность глазированных конфет на 14-29 % по сравнению с конфетами, изготовленными на основе арахиса. Полученные результаты позволяют обосновать дополнительные требования к качеству сырья и технологическим параметрам для гарантирования заданного срока годности глазированных конфет. The multicomponent and complex composition of glazed sweets with praline and praline-type bodies causes migration and oxidative spoilage of fats, which lead to deterioration of organoleptic characteristics. The aim of the study was to study the effect of the properties of raw nut materials and storage temperature on the rate of oxidative processes. An increase in the mass fraction of linoleic acid from 0.9 % to 6.2 % as a result of the migration of body fats into the glaze led to an increase in the rate of oxidative processes, which was confirmed by studies of indicators of oxidative spoilage. After two months of storage at 18 °C, the peroxide number of the fat fraction of the bodies of sweets made with nuts increased from 0.4-0.5 mmol act. O2/kg up to 0.4-1.2 mmol act. O2/kg in the fat fraction of peanut-based sweets, during storage at 18 °C, the peroxide number increased to 0.9-1.6 mmol act. O2/kg At the same time, the induction period of the fat fraction of the bodies of such sweets decreased from 23.5 hours. up to 13.6 hours, i.e. 1.7 times. An increase in temperature to 27 °C led to a decrease in the induction period to 8.4 hours, i.e. 2.8 times. For candy bodies made on the basis of nuts, the induction period after 2 months of storage of sweets at a temperature of 18 °C decreased by 1.2 times. The use of raw nut materials allows to increase the safety of glazed sweets by 14-29 % compared to sweets made on the basis of peanuts. The results obtained make it possible to substantiate additional requirements for the quality of raw materials and technological parameters to guarantee the specified shelf life of glazed sweets.

The use and quality analysis of household compost have become very important issues in recent years due to the increasing interest in local food production and safe, self-produced food. The phenomenon was further exacerbated by the COVID-19 pandemic quarantine period, which gave new impetus to the growth of small home gardens. However, the knowledge associated with making high-quality compost is often lacking in home gardeners. Therefore, the objective of this research was to find answers to the following questions: can the quality of backyard compost be considered safe in terms of toxicity and nutrient content? Can weed seed dispersion affect the usability of backyard compost? In general, can the circulation of organic matter be increased with the spread of home composting? In this study, 16 different house composts were analysed for stability, weed seed contamination, toxic elements, and nutrient content using analysis of variance. The results of the research showed that the quality properties of the composts (including their weed seed dispersion effect) were greatly influenced by the different techniques and raw materials used. The toxicity levels, as well as the content of macro and microelements, were within the parameters of safe-quality compost. The specific macronutrient (Ca, Mg) and micronutrient (Fe, Mn) contents of the tested composts have a similar and, in some cases, more favorable nutrient supply capacity in crop production than the frequently-used cow manure-based composts. With a plan of basic education on composting, there is potential to encourage farmyard composting.
