One of the directions of the rational use of the secondary raw materials of meat industry, including collagen-containing, is its modification in order to obtain protein products enriched with micronutrients for the further use in food production. The presence of active carboxyl end groups in the collagen molecule and complex spatial structure cause the complexation of this protein with various minor nutrients, thereby promoting the creation of a biologically active composite for the enrichment of meat products.

Pyrolysis is considered as an effective and alternative way to treat organic waste and to obtain pyrolysis fuels as well as biochar. The latter may be used for different purposes in industry and agriculture, including use as a long term fertilizer. Biochar, after pyrolysis, is obtained in the form of powder; however from practical point of view it is better to use pelleted or granulated biochar since it significantly enhances biochar?s filed distribution. In our study we compared the efficacy of granulated and pow...

The tanning industry aims at converting the raw hide or skin (a putrescible material) into leather. At each ton of raw hides results 200-250 kg leather, while the untanned solid waste as organic fractions is around 500-600 kg. According to the EU policies on Green and Circular Economy the Action Plan covers the whole cycle: from production and consumption to waste management and use of secondary raw materials. In contrast with the traditional, linear ?extract-transform-use-dispose? economy model, the circular mode...

Studies in the literature on the effect of dietary n-3 and n-6 PUFA on lymphocyte subpopulations in mammalian and poultry studies are contradictory. This might be due to differences in species, basal diet, fat amount, ratio of n-6 to n-3 PUFA and different fatty acids of n-3 PUFA. An inclusion of flaxseed in the diets of chickens can increase the n-3 fatty acids (FA) of poultry meat as it is rich source of ?-linolenic acid. The hepatic lipid metabolism of chickens helps in the incorporation of whole body and muscl...

Wastes from livestock farms contain significant amounts of antibacterial drugs and antibiotic?resistant genes. Due to weak adsorption in the animal's body, antibiotics are released into the environment in an unchanged form or as metabolites in the composition of manure. In addition to the antibacterial agents, the manure of treated animals contains antibiotic?resistant bacteria. The use of manure in untreated form as a soil fertilizer can lead to the spread of antibiotic resistance among soil microorganisms. Compo...

Aflatoxin B1 (AFB1) contamination of coffee beans continues to be a serious issue regarding livestock productivity and human health. AFB1 (secondary metabolites produced by a larger number of Aspergillus spp.) is classified as a Group I carcinogen by the International Agency for Research on Cancer due to the considerable risk to human and animal health. Therefore, monitoring of this toxin by using probiotics during storage became a challenge due to the demand for reduced use of chemical preservatives by consumers....

The issue of biochar application as a non-conventional fertilizer is of growing interest currently. Biochar is a product of the pyrolysis of organic waste for example and unlike conventional fertilizer, biochar is a long-acting agent. The use of such fertilizer should not only increase the yield of crops, but also the sequestration of carbon in the soil and reduce the impact on climate change. An additional advantage of biochar is its developed surface, which makes it possible to use it as a carrier for beneficial...

Biodiesel is a relatively new type of environmentally friendly fuel, which is made from renewable resources. Biodiesel is a mixture of methyl or ethyl esters of fatty acids. It is obtained by re-esterification of vegetable oils or others fat-containing substrate, including animal origin. Iodine and acid numbers of vegetable oils, such as rapeseed, olive, linseed, nut and sunflower, are determined. In addition, conditions for obtaining biodiesel by en-zymatic catalysis using pancreatic lipase as an enzyme and rapes...

Whey cheeses, among which Ricotta is the famous one, are considered valuable food products from a nutritional point of view, enabling sustainable valorization of whey, a major by-product of dairy industry. As a consequence of their rich composition, high moisture content and pH, whey cheeses favor microorganism growth. That is why, producers have to pay special attention to avoid spoilage and risks to the consumer?s health, recalls and economic losses. They also need to meet health-conscious consumers demand for h...
