A dual objective of food storage is to retain nutritional value and safe consumption over time. As supply chains have globalized, food protection and preservation methods have advanced. However, increasing demands to cater for larger volumes and for more effective food storage call for new technologies. This paper examines promising meat preservation methods, including high pressure process, ultrasounds, pulsating electric and magnetic field, pulsed light and cold plasma. These methods not only make it possible to obtain meat and meat products with a longer shelf life, safer for health and without preservatives, but also are more environment-friendly in comparison with traditional methods. With the use of alternative methods, it is possible to obtain meat products that are microbiologically safer, whilst also high quality and free from chemical additives. Moreover, these new technologies are also more ecological, do not require large quantities of energy or water, and generate less waste.

This study aimed at the analysis of the impact of the age of horses and selected substances (lactic acid, malic acid, salt phosphates, and phosphates with rosemary) on the quality of horse meat during cold storage. Samples of the longest thoracic muscle obtained from 12 half-carcasses of horses from two age groups: from 4 to 7 years and from 8 to 12 years constituted the research material for the analysis. The addition of each of the substances (lactic acid, malic acid, salt phosphates, phosphates with rosemary) used to marinate this meat increased the color brightness and reduced the value of shear force and hardness compared to the control sample (P < .05) in both age groups. The use of lactic acid for marinating in the case of meat from both younger and older horse carcasses affected the lowest sensory evaluation scores (P < .05) of this meat compared to the control sample and those for which other substances were used.

This study determined the accumulation of selected heavy metals (Pb, Cd, Hg and As) in tissues of wild boar. The tested animals were divided into three age groups, which allowed analysis of the statistical/mathematical relationship between their age and contamination of their tissues. For determination of heavy metal content, samples were taken from the longissimus muscle of the back and from the tail lobe of the liver. It has been stated that, in wild boar, accumulation of lead and cadmium in muscle and liver increases with age. However, statistical differences were found most frequently between the youngest and oldest animal groups only. Moreover, in no single case, was the maximum permissible level exceeded in muscle for lead, cadmium or mercury, and arsenic was not detected above 0.001 mg/kg. In the >3 year group, the maximum permissible level of cadmium (0.5 mg/kg) was exceeded in two liver samples.

The aim of this study was to analyse the impact of differentiation of cooking and baking temperatures on the chemical composition, colour, sensory evaluation, shear force and muscle texture parameters of the longissimus dorsal muscle of wild boars. It was shown that the increase in the final temperature during cooking and baking caused a decrease in the water content in the muscle, and as a result of the density of the tissue structure after the loss of this component, the fat content in the meat after heat treatment increases. Cooking at 80-90°C and baking at 150-175°C contributed to more favourable texture parameters such as hardness of cycles 1 and 2 and gumminess. In addition, it was found that the heat treatment affects the increase of the yellow colour and meat brightness, and at the same time the reduction of the a* parameter. Efecto de métodos de tratamiento térmico seleccionados sobre los parámetros de composición química, color y textura del músculo dorsal largo (longissimus dorsi) de los jabalíes RESUMEN El objetivo del presente estudio fue analizar el impacto producido por la aplicación de diferentes temperaturas de cocción y de horneado en la composición química, el color, la evaluación sensorial, la fuerza de corte y los parámetros de textura muscular del músculo dorsal longissimus de los jabalíes. Se demostró que el aumento de la temperatura final durante la cocción y el horneado provocó la disminución del contenido de agua del músculo, y que, debido a la densidad de la estructura del tejido tras la pérdida de este componente, después del tratamiento térmico se incrementó el contenido de grasa en la carne. La cocción a 80-90°C y el horneado a 150-175°C dieron como resultado parámetros de textura más favorables, tales como dureza de los ciclos 1 y 2 y la gomosidad. Además, se constató que el tratamiento térmico provoca aumento del color amarillo y del brillo de la carne, reduciendo al mismo tiempo el parámetro a*.

The aim of the study was to examine the nutritional behaviour of young adults depending on gender. A survey was conducted among 467 young adults using the “Questionnaire for the study of nutritional behaviour and opinions on food and nutrition”. Questions concerned the frequency of consumption of selected groups of food products. The questionnaire was supplemented by questions regarding the number of portions of fruits and vegetables consumed, putting sugar in drinks, putting salt in dishes and the number of glasses of water drunk. Differences in nutritional behaviours were determined using the χ2 test, at p < 0.05. The dietary choices of women more often than those of men corresponded to the principles of healthy nutrition, related to a greater number of meals consumed during the day, more frequent consumption of fruits and vegetables and the selection of products with lower energy value or preferring healthier methods of culinary processing. Health education programs should prevent the emergence of unfavourable dietary habits such as skipping breakfast or other meals or limiting the consumption of fruits and vegetables and frequently replacing them with high-energy snacks.

Horsemeat has a strictly defined group of consumers whose demand varies depending on the country or region. There is no tradition of consuming horsemeat in Poland. From a technological point of view, this raw material is as good as other types of meat. In the opinion of the consumer, compared to other species of animals, horsemeat is characterized by an intense red-brown colour and greater cohesiveness resulting from the type of muscle fibres. This meat has a sweetish taste due to the high carbohydrate content. The management of horsemeat often involves the use of modern freezing methods. Freezing horsemeat with the use of liquefied carbon dioxide is a method that increases its suitability for consumption as well as for export purposes in comparison with the traditional air-cooling method. To eliminate the unfavourable quality features of horsemeat, there are substances used to improve the functional and sensory properties of this meat. This paper discusses the research and development work carried out in the field of horsemeat quality and selected methods contributing to its improvement.
