Introduction. Some ingredients of plant origin possess both antioxidant and bacteriostatic properties. If used in the food industry, they can inhibit microbiological and oxidative damage, thus increasing the shelf life of meat products. Oregano extract is one of such substances, which means that it can be used as an antioxidant and preservative. Therefore, the study of this plant has a significant theoretical and practical potential for the food industry. Study objects and methods. The present research featured ground trimmed beef. The samples with 20% of fat tissue were used to determine the microbiological parameters, while the samples with 30% of fat were used to obtain data on oxidative stability. The control sample contained no additional ingredients. The sample with food additives was pre-treated with acidity regulators and antioxidants, namely sodium acetate E262, ascorbic acid E300, sodium ascorbate E301, sodium citrate E331, and rosemary extract E392. The sample with oregano extract was pre-treated with oregano extract (Origani vulgaris herba L.) in the ratio of 5 g of extract per 1 kg of meat. The extract had been dissolved in 100 g of water. The samples were stored at 4 ± 2°C for 12 days. A CM5 spectrophotometer (Konica Minolta, Japan) was used to determine the color characteristics. The induction period of oxidative stability was determined using an Oxitest oxidative stability analyzer (Velp Scientifica, Italy). The studies were conducted in Austria, Linz. Results and discussion. Oregano extract stabilized the redness rating. For the sample with oregano extract, the induction period of oxidative stability was twice as long as for the control sample and the sample with antioxidants. In addition, oregano inhibited the growth of aerobic and anaerobic microorganisms. Conclusion. The antioxidant and antimicrobial properties of oregano extract prolong the shelf life of ground beef, which makes it possible to reduce the amount of food additives.

Main Component

The production of meat products is one of the most important sectors of the national economy. Meat and meat products are necessary source of nutrition for humans, as they are the main source of protein for the body. Residents of the metropolis often do not have enough time for proper nutrition. Ready-made products or semi-finished meat products with a long shelf life become the main component in the diet of the population. The share of consumption of sausages and other meat delicacies is growing every year [8]. By adding chemical preservatives to food, it is possible to slow down or completely prevent the development of microflora – bacteria, yeast, as well as extend the safety of products. The effectiveness of using chemical preservatives depends on their concentration, nature, and acidity of the medium. A special group of food additives that slow down the deterioration of food (meat, fish, poultry, vegetables, etc.) consists of antibiotics. The use of antibiotics allows you to save food raw materials and certain types of food products for a longer time, sometimes to extend their shelf life by 2 to 3 times. Antibiotics that are added directly to the food product, such as nisin and natamycin, have gained some acceptance in the food industry.

Banana pseudo-stem (BPS), which is rich in fibre and polyphenols, is a potential functional ingredient for the food industry. In this study, BPS was added at concentrations of 1.5, 3.0, and 4.5 g/kg to a minced pork batter to evaluate its performance as a filler and to pork burger patties to evaluate its performance as a natural antioxidant. The effects of BPS were compared with those of carrageenan and ascorbate, which are a conventional binder and antioxidant, respectively. The performance of BPS was similar to that of carrageenan in terms of the cooking yield and texture of the cooked batter. BPS reduced the brightness of fresh patties and appeared to reduce oxidative discolouration during the frozen storage of raw patties. Moreover, BPS reduced the levels of thiobarbituric acid reactive substances (TBARS) during the refrigerated and frozen storage of cooked patties. A greater decrease in TBARS formation was observed with 4.5 g BPS/kg compared with 0.5 g sodium ascorbate/kg during refrigerated storage. In contrast to ascorbate, BPS promoted the presence of lipid-derived volatile compounds induced by thermal breakdown in the headspace of cooked patties. Nonetheless, this effect was reduced as the amount of BPS in the patties increased. In cooked minced meat products, BPS could increase cooking yields and lipid oxidative stability during storage and might result in a more intense flavour.

Active Food Packaging

Public concern on the excessive use of synthetic food additives has raised a great interest to use natural products due to their potential in food and pharmacological industries. Nowadays, chemical food additives are questioned due to their contribution to the health risks and environmental impacts. Among natural additives, essential oils (EOs) are extracted from aromatic compounds and responsible for their biological activities namely antimicrobial and antioxidant capacity. Incorporation of bio-active compounds particularly EOs directly in food or edible/biodegradable food packaging seems to enhance the shelf life and quality characteristics of processed food and protect the consumers against oxidative and bacterial deterioration effects. However, inclusion of EOs in films/coatings for food packaging may put some effects on various properties (optic, tensile and etc.), which can affect the consumer acceptability. Their addition in food can cause some allergic and hypersensitivity reactions to the individuals who use them often. This paper aims to review the latest findings on the use of EOs incorporated with edible/biodegradable films and coatings to enhance the shelf life and quality of the food. Further investigations about essential oils are expected to clarify their exact action and build up their standard use in food industry.

The uncontrolled growth of lactic acid bacteria (LAB) in meat and meat products leads to product spoilage, and thus shortens product shelf life. Although food additives are known to decrease LAB growth, this effect has not been analyzed in detail. Here, a detailed analysis was performed of the effects of sodium chloride, sodium polyphosphate, sodium lactate, sodium nitrite/nitrate, and garlic on the growth of the Lactobacillus plantarum in culture medium. The results were used to design and test experimental formulations of meat products. Initially, the effect of food additives on L. plantarum was evaluated using a Fractional Factorial Design (FFD), followed by a Central Composite Rotatable Design (CCRD). The Modified Gompertz Model was adjusted to the growth curves to determine the Kinetic parameters of bacterial growth (logarithmic increase in the population, specific growth rate, and lag phase extension). Higher sodium lactate and sodium chloride levels had a negative impact on L. plantarum growth parameters (p?0.05). Therefore, we designed experimental formulations of mortadella and smoked pork sausages containing 4% sodium lactate (w w-1) and 2.4-3.5% sodium chloride (w w-1), and determined LAB growth from samples of stored products produced according to these formulations, in order to determine product shelf life. There was an increased lag phase of LAB growth for most experimental formulations. Also, the experimental smoked pork sausages had a longer shelf life, which was increased by at least 22 days, suggesting that the proposed formulation, with higher than standard lactate concentration, increased the product’s shelf life.

Abstract Oxidation and microbial spoilage have a negative effect on the quality of meat and meat products, causing changes in their sensory and nutritional properties. Herbs contain biologically active compounds, like phenols with antioxidative and antimicrobial properties. Phenols can be used as substitutes for commercial antioxidants to prevent lipid oxidation, thus maintaining the colour and flavour of the product. The aim of the study was to investigate the the potential use of herbal extracts in ethanol/water application for the maintenance of pork meat quality during storage. Four herbs growing in Latvia — nettle (Urtica dioica L.), lovage (Levisticum officinale L.), oregano (Origanum vulgare), and horseradish (Armoracia rusticana L.) were chosen for the study. An optimal ethanol concentration for the extraction of the phenolic compounds was obtained with ethanol 50%/water 50% concentration (v/v). Prepared herbal extracts were added to chilled pork to determine the quality of the pork during storage. Changes in meat quality and its sensory properties for chilled pork without extracts appeared on day 18 of storage. Negative changes in sensory properties of meat samples with nettle extract were observed on day 22 of storage, and with lovage, oregano, and horseradish extracts on day 32. Statistically significant differences (p ≤ 0.05) were observed for microbiological indices between pork samples with herbal extracts and the control sample.

Palm olein is commonly used in cooking and food processing, however, it is susceptible to oxidation due to its high unsaturated fatty acids content. An antioxidant is added to the oil by oil manufacturer to inhibit lipid oxidation and increase the shelf life of the oil. However, most of the antioxidants are synthetic antioxidants that may not be safe for consumption and decomposed at high temperature during frying or processing. In this study, the antioxidant properties of mangrove apple fruit extract (MAFE), as well as the oxidative stability of palm olein with and without MAFE, were investigated. Palm olein added with MAFE (100 and 200 ppm) and without MAFE were kept at 65°C in an oven for 24 days under accelerated storage. The results showed that MAFE contained high total flavonoid compound (26.06±0.30 mg QCE/g extract) and total phenolic compound (12.21±1.31 mg GAE/g extract). The IC50 values of antioxidant activities of MAFE calculated by DPPH and ABTS•+ were 31.16±0.76 µg/mL and 97.32±3.27 µg/mL, respectively. The palm olein samples added with MAFE showed significantly lower peroxide value, p-anisidine value, TOTOX value, conjugated dienes and conjugated trienes after 24 days of storage compared to the palm olein without MAFE (control sample). The oxidative stability of palm olein added with 200 ppm MAFE was higher compared to the palm olein added with 100 ppm MAFE and control sample. Therefore, MAFE has the potential to be used as a source of natural antioxidant to reduce the lipid oxidation and prolong the shelf life of food products.

Minced Meat

When creating meat products, one of the main indicators is the biological value of the product. The biological value of proteins depends on the degree of their assimilation, in animal proteins is greater than in vegetable. More than 90% of amino acids are absorbed from animal proteins in the intestine. An important indicator of the biological value of proteins is their attack by digestive enzymes - the property to be hydrolyzed with the participation of enzymes in the gastrointestinal tract.Enzymatic methods for determining the biological value of a protein are one of the simplest and at the same time objective methods for determining its ability to be broken down by proteolytic enzymes in the gastrointestinal tract.The article presents a study on the biological value of minced meat semi-finished products. For the studies we used chopped semi-finished products (cutlets) control sample and three test samples with partial introduction into the formulation of food additives based on animal and vegetable raw materials - 0.5 %, 0.75 % and 1.0 %, respectively. Hydration of the additive is 1:15. The food supplement contains g / 100 g: sodium alginate - 60, whey protein - 16, soy fiber - 24. To determine the biological value of the products by the enzymatic method used a device for hydrolysis of proteins. The essence of the method is a six-hour hydrolysis by enzymes of a sample of the finished product. The first stage is fermentation with pepsin (3 hours), the second stage is trypsin (3 hours). With hourly selection of hydrolysis products to determine the degree of digestibility at a certain stage of the study. It is proved that the addition to the recipe of chopped semi-finished food mixture is advisable, as it allows to obtain chopped semi-finished product with better digestibility. The digestibility of the experimental samples was slightly higher than the control. The digestibility index for control was – 69 %, and for experimental – 68-74 %. Therefore, according to research, we can say about the feasibility of using additives in the production of minced meat semi-finished products with a share of replacement of basic raw materials from 8 % to 16 %.

Pinni, a native heat dried sweet produce ready by roasting cereal flours mainly, with added khoa (desiccated milk) and sugar has a shelf-life of a few days under marketplace. In this study, result of preservers viz. i.e., cardamom powder and rosemary on the storage-life of pinni stored at 30±1˚C was investigated. Two packaging techniques viz., conventional cardboard boxes and polystyrene tray were compared for physico-chemical, quality of pinni during storage for 21 days and 28 days respectively at 30±1˚C. During storing, several variations took place in physico-chemical appearances, the changes being faster in control samples packed in both packaging materials as compared to cardamom and rosemary extract added pinni samples. The average tyrosine content for fresh pinni was 9.75 μg/5ml in control, 9.35 μg/5ml in cardamom and 9.45 μg/5ml in rosemary extracted added sample which increased significantly (p<0.05) to 13.87 μg/5ml, 13.59 μg/5ml and 13.23 μg/5ml respectively when packed in cardboard boxes similar results were found when pinni packed in polystyrene tray. There was slight effect of preservers on the excellence of pinni when packed in cardboard boxes, but changes were slower in pinni when packed in polystyrene tray. Pinni packaged in polystyrene tray stored at 30±1˚C, in the presence rosemary extract, was stable for 28 days and have shelf life 14 days more than control sample.

In this article, several applications of materials in food packaging and food safety are reviewed, including: polymers as high barrier packaging materials, natural substances as potent antimicrobial agents, and the efficiency of antimicrobial films in food industry. Active antimicrobial food packaging systems are supposed not only to passively protect food products against environmental factors, but also to inhibit or retard microbial growth on the food surface, extending the shelf life of products. Edible films can be incorporated into conventional food packaging systems with a dual purpose as an edible and antimicrobial component. Applications of antimicrobial films to fruits, vegetables and meat products have received increasing interest because films can serve as carriers for various natural antimicrobials that can maintain fresh quality, extend product shelf life and reduce the risk of pathogen growth. In the future, eco-friendly antimicrobial packaging films are promising food packaging materials because its biodegradability provides sustainable development for a modern community.In this article, several applications of materials in food packaging and food safety are reviewed, including: polymers as high barrier packaging materials, natural substances as potent antimicrobial agents, and the efficiency of antimicrobial films in food industry.

The Impact

The food industry has endeavoured to move toward the direction of clean labelling. Therefore, replacing synthetic preservatives with natural plant extracts has gained significant importance. It is necessary to determine whether products enriched with such extracts are still accepted by consumers. In this study, consumer tests (n = 246) and sensory profiling were used to assess the impact of ethanol extracts of spices (lovage, marjoram, thyme, oregano, rosemary, and basil; concentration 0.05%) on the sensory quality of pork meatballs and hamburgers. The desirability of meat products with spice extracts to consumers depended on the added extract. The highest scores were for products with lovage extract, whose sensory profile was the most similar to the control sample without the addition of an extract (with higher intensity of broth taste compared with the others). Products with rosemary and thyme extracts were characterised by lower desirability than the control. This was related to the high intensity of spicy and essential oil tastes, as well as the bitter taste in the case of products with thyme. The studied extracts of spices allow for the creation of meat products (meatballs and hamburgers) with high consumer desirability, however, the high intensity of essential oil and spicy tastes might be a limitation.
