The high content of iodine in dried algae has allowed it to be used as a physiologically functional food ingredient in the technology of fortified foods, which can help prevent iodine deficiency. The aim of this research was to develop a technology for food products enriched with iodine (Italian crispbreads), as well as fermented dairy products (thick and drinking yoghurts with various fruit fillings). The brown algae Laminaria saccharina, which originates from the islandFrøya (in Norway), was used to enrich the products with iodine. This algaewas grown on the farms of the company ”Energy Solutions AS” and was dried by various methods of low-temperature drying (heat pump at a temperature of minus 10 ∘C, drying in 1-3 layers; vacuum freeze drying with pre-storage at a temperature of minus 8 ∘C; and pre-freezing and storing at a temperature of minus 25 ∘C for 2-6 days). The chemical composition of the algae was studied. The findings showed that the modes of pretreatment of algae and the method of cold drying did not influence the following indicators (in % of the total mass of dried algae): the mass fraction of water (6.00±0.50% to 6.93±0.50%),ash (46.40-50.14%), andsodium chloride (31.00±1.75%). The above technological factors substantially affected the content of protein and iodine in the dried algae. Thus, the mass fraction of protein varied from 5.88% to 12.35% per total mass, and iodine varied from 0.367% to 0.522% in terms of dry matter. The optimal dosage of dried algae for adding to raw material was calculated (which provided anabove-stated iodine content of % of the recommended level of adequate consumption in 100g of the developed products): from 66% in crispbreads to 88% in fermented dairy products. All new products provided a high level of organoleptic evaluation. Keywords: brown algae, Laminaria saccharina, iodine, functionalproduct, crispbreads, drinking yoghurts, thick yoghurts

The development of food products implies ensuring the optimal composition and ratio of the basic components, as well as their technological compatibility. A priori, the quality of raw materials, the optimal formula of the product and the efficiency of the technological process determine the quality of products, including biological value. The use of whole-cell sensors such as infusoria Tetrahymena pyriformis is most productive for screening biological studies. At present, for a comprehensive assessment there are no data on the use of simplest technology of fermented dairy products and the design of their biological value. The purpose of this research is to develop a methodology for creating whole-milk products of optimal biological value using the express method of biotesting. The research object was yogurt with the ratio of the mass fraction of fat and protein in the range of 0.36 ÷ 1.5, sucrose in the range of 5 ÷ 10%. An express method for determining the relative biological value of fermented dairy products using test organisms and an original methodology for creating whole-milk products of optimal biological value have been developed. A software has been developed to calculate formula of the product optimized for the following indicators: the relative biological value of the product, the cost of raw material and basic materials. The methodology is a tool to assist industry organizations in improving production technologies and quality management systems.

Abstract Background Previous studies have suggested that the consumption of probiotic fermented dairy products (PFDP) may have a protective effect on respiratory tract infections (RTIs). However, the results of studies are inconclusive. We aimed to systematically investigate the effect of PFDP on RTIs by performing a meta-analysis of randomized controlled trials (RCTs). Methods PubMed and Scopus databases were systematically searched up to October 2020 to identify eligible RCTs. Meta-analysis outcomes were risk of incidence of upper (URTIs ) and lower (LRTIs ) respiratory tract infections. A random-effects model was used to pool the relative risks (RR) and corresponding 95 % confidence intervals (CI) for outcomes following conception of PFDP. Results A total of 22 RCTs, with a total sample size of 10,190 participants, were included in this meta-analysis. Compared with placebo, consumption of PFDP had a significant protective effect against RTIs in the overall analysis (RR = 0.81, 95 %CI: 0.74 to 0.89) and in children (RR = 0.82, 95 %CI: 0.73 to 0.93), adults (RR = 0.81, 95 %CI: 0.66 to 1.00), and elderly population (RR = 0.78, 95 %CI: 0.61 to 0.98). The significant decreased risk of RTIs was also observed for URTIs (RR = 0.83, 95 %CI: 0.73 to 0.93), while, this effect was marginal for LRTIs (RR = 0.78, 95 %CI: 0.60 to 1.01, P = 0.06). The disease-specific analysis showed that PFDP have a protective effect on pneumonia (RR = 0.76, 95 %CI: 0.61 to 0.95) and common cold (RR = 0.68, 95 %CI: 0.49 to 0.96). Conclusions Consumption of PFDP is a potential dietary approach for the prevention of RTIs.

  Lactobacilli are essential and important biological objects used in food pro-duction and medicine. One of the sufficient problems is fast, reliable and highly specific identification of lactobacilli in the scientific research and cur-rent production control. We represent two species-specific real-time PCR in the present study to discriminate L. rhamnosus and L. casei basing on the unique peptidoglycan-hydrolase genes p40 and p75 respectively. PCR pri-mers and probes were designed to provide high specificity discrimination via high temperature of PCR annealing stage. High efficiency of the reactions is provided by the size of amplified DNA fragments minimization. Reliable re-producibility of the target sequences amplification and fluorescence detec-tion provide a basis for the future creation of industrial test-systems for op-erational control in the production of fermented dairy products.

Subject of study. In the Ukrainian market, most ща fermented dairy products are traditional and ерун фку in great demand among various segments of the population. However, for a certain category of consumers, this segment of dairy products is not recommended for use due to lactase deficiency, which prevents the breakdown and assimilation of lactose containing dairy products. Consumption of dairy products causes discomfort and disorders in the gastrointestinal tract and malaise of such people. This review article is based on the results of basic and applied research of foreign and domestic scientists in this area, it indicates ways to solve this problem and the feasibility of the presence of these products in the diet of this group of people. The aim of the work is a systematic analysis of modern scientific information on the ways to reduce lactose content by the use of fermenting preparations based on strains with β galactosidase activity and integrated use of bacterial cultures and enzyme preparation of β galactosidase in the production of fermented dairy products. Results and discussion. It is shown that there are strains of microorganisms that have a sufficiently high β-galactosidase activity. However, the actual breakdown of lactose occurs in small quantities. The analysis of the literature showed that most often for the production of milk and dairy products with low lactose or lactose-free content, the enzyme lactase is used, which breaks down lactose into individual sugars – glucose and galactose. And the combination of microorganisms and enzyme preparation allows expanding the range of products and meet the needs of lactose intolerant consumers. Scope of research results. The obtained search results will be used in the development of technologies for fermented dairy products with low lactose or lactose-free content.

AbstractRecent dairy product studies have suggested that fermented rather than non-fermented dairy products might provide benefits on cardiovascular health, but the evidence is inconclusive. Therefore, we investigated whether fermented and non-fermented dairy products have distinct associations with the risk of incident CHD in a population with high dairy product intake. The present study included a total of 1981 men, aged 42–60 years, from the Kuopio Ischaemic Heart Disease Risk Factor Study, with no CHD at baseline. Dietary intakes were assessed with instructed 4-d food records. We used Cox’s proportional hazards regression model to estimate the associations with the risk of CHD. Fatal and non-fatal CHD events were ascertained from national registries. During a mean follow-up of 20·1 years, 472 CHD events were recorded. Median intakes were 105 g/d for fermented (87 % low-fat products) and 466 g/d for non-fermented dairy products (60 % low-fat products). After adjusting for potential confounders, those in the highest (v. lowest) intake quartile of fermented dairy products had 27 % (95 % CI 5, 44; P-trend=0·02) lower risk of CHD. In contrast, those in the highest intake quartile of non-fermented dairy products had 52 % (95 % CI 13, 104; P-trend=0·003) higher risk of CHD. When analysed based on fat content, low-fat (<3·5 % fat) fermented dairy product intake was associated with lower risk (hazard ratio in the highest quartile=0·74; 95 % CI 0·57, 0·97; P-trend=0·03), but high-fat fermented dairy and low-fat or high-fat non-fermented dairy products had no association. These results suggest that fermented and non-fermented dairy products can have opposite associations with the risk of CHD.
