At present the olive oil industry produces large amounts of secondary products once considered waste or by-products. In this paper, we present, for the first time, a new interesting olive by-product named “dried destoned virgin olive pomace” (DDVOP), produced by the pomace oil industry. The production of DDVOP is possible thanks to the use of a new system that differs from the traditional ones by having the dryer set at a lower temperature value, 350 °C instead of 550 °C, and by avoiding the solvent extraction phase. In order to evaluate if DDVOP may be suitable as a new innovative feeding integrator for animal feed, its chemical characteristics were investigated. Results demonstrated that DDVOP is a good source of raw protein and precious fiber; that it is consistent in total phenols (6156 mg/kg); rich in oleic (72.29%), linoleic (8.37%) acids and tocopherols (8.80 mg/kg). A feeding trial was, therefore, carried out on sheep with the scope of investigating the influence of the diet on the quality of milk obtained from sheep fed with DDVOP-enriched feed. The resulting milk was enriched in polyunsaturated (0.21%) and unsaturated (2.42%) fatty acids; and had increased levels of phenols (10.35 mg/kg) and tocopherols (1.03 mg/kg).

Abstract In the technological process of the steelmaking plant, secondary products are produced in parallel with the production of the main product, which have the character of secondary by products or industrial waste. The major secondary products of steelmaking production include waste gases, process fluids, flue dust, sludge, slags and mill scales. The paper presents the results of research project directed to the utilization of demetallized steelmaking slag and oxygen converter flue dust in charge of top blowed oxygen converter. The influence of demetallized slag additions on slag regime in converter and chemical composition of final slag is described and discussed. Recommendations concerning amount of demetallized slag additions are also presented. Flue dust was recycled in form of briquettes. No significant effect of the recycling demetallized converter slag and flue dust briquette on process of hot metal refining and on quality of produced steel were recorded. Regarding the achieved results it can be confirmed that the use of the secondary products like demetallized slag and convertor flue dust in form briquettes, is environmentally acceptable as well as the use of natural materials and poses no increased risk to human health or the environment.

Tannase is an enzyme that causes hydrolysis of a group of tannins (gallo-tannins) to gallic acid and glucose. This enzyme is of importance due to its numerous applications in many fields, such as in the food industry by enhancing tea and coffee flavor and improving the quality of fruit juices rich in tannins. Tannase is also of importance in improving the quality of animal feed. Gallic acid is applied in the drug industry, and the production of antioxidants is used in the oil industry. This study was carried out to improve production of tannase from genus Bacillus using spent tea as a substrate by submerged fermentation and applying the statistical design Response Surface Methodology (RSM). Five parameters were considered, and each parameter was studied at five levels. They were temperature range (25 to 45˚C), pH (3–8), incubation period (24–120 hours), spent tea (0.5–2.5%) and rotation speed (100–300rpm). Results obtained revealed that optimum conditions for maximum production of tannase were: temperature at 35˚C, pH at 5, incubation time of 48 hours, spent tea concentration 1.5%, and rotation speed of 150 rpm. We recommend that further studies be carried out to clarify and determine the properties of crude and purified enzymes.

Phenylethyl isothiocyanate (PEITC) was reported as a useful antioxidant, anti-inflammatory, and chemopreventive agent. Due to technological and stability issues, it is necessary to be able to extract PEITC from its natural matrix (watercress) through sustainable and scalable methodologies. In this article, we explored, for the first time, the extractive capacity of aqueous micellar systems (AMSs) of two non-ionic surfactants. For this, we compared the AMSs with conventional organic solvents. Furthermore, we developed and optimised a new integral PEITC production and extraction process by a multifactorial experimental design. Finally, we analysed the antioxidant capacity by the oxygen radical absorbance capacity (ORAC) and ABTS methods. As results, the AMSs were able to extract PEITC at the same level as the tested conventional solvents. In addition, we optimised by response surface methodology the integrated process (2.0% m/m, 25.0 °C, pH 9.0), which was equally effective (ca. 2900 µg PEITC/g watercress), regardless of the surfactant used. The optimal extracts showed greater antioxidant capacity than pure PEITC, due to other antioxidant compounds extracted in the process. In conclusion, by the present work, we developed an innovative cost-effective and low environmental impact process for obtaining PEITC extracts from watercress by-products.

Fungi, yeasts, and bacteria are common microorganisms on cereals used in malting and brewing industries. These microorganisms are mostly associated with the safety and quality of malt and beer, but also with the health safety of by-products used in animal nutrition. The real problem is their harmful metabolites—toxins that, due to their thermostable properties, can easily be transferred to malting and brewing by-products. Besides fungal metabolites, other toxins originating from plants can be harmful to animal health. Precise and accurate analytical techniques broadened the spectrum of known toxins originating from microorganisms and plants that can pose a threat to animal health. Multi-(myco)toxin analyses are advanced and useful tools for the assessment of product safety, and legislation should follow up and make some important changes to regulate yet unregulated, but highly occurring, microbial and plant toxins in malting and brewing by-products used for animal feed.

In the past 10 years, the average demand for meat and milk across the world has significantly increased, especially in developing countries. Therefore, to support the production of animal-derived food products, a huge quantity of feed resources is needed. This paper does not present original research, but rather provides a conceptual strategy to improve primary production in a sustainable way, in relation to forthcoming issues linked to climate change. Increases in meat and milk production could be achieved by formulating balanced diets for ovines based on alfalfa integrated with local agricultural by-products. As the central component of the diet is alfalfa, one goal of the project is increasing the yield of alfalfa in a sustainable way via inoculating seeds with symbiotic rhizobia (i.e., Sinorhizobium meliloti). Seed inoculants are already present on the market but have not been optimized for arid soils. Furthermore, a part of the project is focused on the selection of elite symbiotic strains that show increased resistance to salt stress and competitiveness. The second component of the experimental diets is bio-waste, especially that obtained from olive oil manufacturing (i.e., pomace). The addition of agro-by-products allows us to use such waste as a resource for animal feeding, and possibly, to modulate rumen metabolism, thereby increasing the nutritional quality of milk and meat.

The aim of this thesis was to evaluate the changes of the microbiological quality of milk during storage. Fresh pasteurized milk was used for the laboratory experimentations. Cooling chain of the samples was broken for 8 and for 12 hours at different temperatures (22–30 °C). In these samples, total count of psychrotrophic microorganisms was assessed.Technological indiscipline, i. e. higher storage temperature (24 °C and more), was associated with higher increase of total count of microorganisms and psychrotrophic microorganisms. Microbiological results proved that the samples stored under standard conditions were of very good quality. However, in fresh pasteurized milk the representation of total count of microorganisms and psychrotrophic microorganisms meets fully the norm requirements. It is necessary respect a sustentation of a lower temperature of fresh pasteurized milk during storage, especially in summer months.

A significant group of inedible by-products from industrial slaughterhouses that can be used as a raw material for processing into quality feed for pigs and pets are byproducts of slaughtered poultry. The poultry industry yields a large amount of inedible byproducts of which the removal or processing requires hygienic and economic solutions. These activities primarily include the protection of the environmental from degradation processes and biological pollution, as well as securing high-protein animal feed. The incorporation of inedible slaughtered poultry by-products into food for animals involves the application of various technological processes. These processes should be simple and feasible for investments where it is necessary to obtain a quality product. At the same time, it must be taken into account that the production process does not create new secondary products or waste gases that could contaminate the environment. Scientific knowledge in the field of exploitation of inedible slaughtered poultry by-products provides the necessary basis for calculating the amount of certain types of raw materials.

This article conducts historiographical and quantitative analysis of the prime economic media in the Russian Empire of the late XIX – early XX centuries – “Journal of Finance, Industry and Trade”. The journal was issued from 1885 to 1917 being the official publication of the Ministry of Finance. The materials published in the journal contain reference and analytical information. High quality of the analytical articles was ensured by competent authors – prominent national economists of that time. The goal consists in studying the dynamics of reflection of complex economic processes that unfolded in the prewar 1913 in the journal. Characteristic is given to the composition of the team of authors in 1913. Quantitative analysis of the content of all 52 issues is conducted for the first time in accordance with the dynamics of quarterly distribution of the topics of analytical publications. The author suggests possible interpretations of changes in thematic specialty of the journal throughout the year, and formulates a hypothesis on correlation between these changes and the dynamics of industrial stock index developed by L. Borodkin and G. Perelman by analogy with the famous Dow Jones Industrial Average. Decline in journal’s interest to the industrial problems is noticed until the fourth quarter of 1913; then the favorable conjuncture on the oil market explains the frequency of occurrence of the category of “industry” due to the articles dedicated to oil industry.
