The fatty acid composition of wild sea bass (Dicentrarchus labrax L.) and gilthead sea bream (Sparus auratus L.) were compared with gas chromatography. These two species are widely cultivated in Europe and represent a significant portion of consumed fish in the region. The aim of the present work was to compare the nutritional value of fatty acids in the flesh of wild sea bass and sea bream. Significant differences were observed in the saturated and poly-unsaturated fatty acid content. The presence of lauric, myristic and palmitic acids in the flesh of sea bream in quantities far exceeding those in sea bass make sea bream less suitable for preventing cardiovascular diseases. The poly-unsaturated n-3 fatty acids with both anti-atherogenetic and anti-inflammatory action in sea bass surpass those of sea bream by a total of 30%. Sea bass also contains 60% more C22:6n-3. Compared to sea bream, sea bass appears to be more suitable for the diet of people suffering from cardiac diseases, angiopathy, inflammations and Alzheimer’s disease.

The consumption of soy has long been associated with various health-enhancing effects including hypocholesterolemia, antihypertension, alleviation of post-menopausal symptoms, and reducing risks of ovarian cancer and cardiovascular diseases. Past studies have indicated that these effects are mediated by bioactive components of soy such as isoflavones and bioactive peptides. However, some of these bioactive components could only confer health benefits upon bioconversion by gastrointestinal microorganisms in the intestines. This has led to increased interest to evaluate the possibility of utilizing probiotics to enhance the bioactivities of soyfoods. Probiotics are live microorganisms that could exert health benefits on the host when administered in adequate amounts. Probiotic-fermented soyfoods have been shown to have increased antihypertensive properties and could better alleviate menopausal associated disorders. However, this area is relatively new and although seemed promising, most of the recent findings have emphasized on in vitro evaluations, while the lack of in-vivo evidence and/or incompatible outcomes between in vitro experiments and in-vivo trials has led to the need to better understand the exact mechanisms involved. This present review highlights some of the benefits of soy and addresses the currently investigated bioactivities of probiotic-fermented soyfoods.

Determination of consumers’ acceptance level of sushi meal among Czech respondents was the main aim. The survey included 1352 respondents that filled in a questionnaire on their demographic characteristics and food preferences regarding their acceptance of sushi meal. Additionally, 79 volunteers participated in sorting sushi among other 14 popular meals in the Czech Republic, according to their assumed situations. The results indicate that sushi is highly accepted among Czech consumers (more than 80% of respondents consume sushi) due to sensory characteristics and health benefit claims of sushi. The main barrier for sushi acceptance is sushi being a cold meal. The study emphasized that sushi price highly influences not only consumption frequency but also acceptance of sushi among respondents who declared not consuming this type of meal.

The fatty acid compositions of the total lipid, neutral and polar lipid fractions in the liver and muscle of Capoeta sieboldii and Capoeta baliki from Tödürge Lake were determined. Major fatty acids found in total lipid (TL) and neutral lipid (NL) in liver and muscles were C16:0, C16:1 n-7, C18:1 n-9, C18:1 n-7, C20:4 n-6, C20:5 n-3, C22:5 n-3, and C22:6 n-3. Beside these acids, C18:0 was another notable fatty acid in polar lipid (PL) fraction of the tissues investigated. The n-3/n-6 ratio, which is an indicator of health benefits of fish oils, was between 2.89 (PLs of liver) and 5.84 (PLs of muscle) in C. baliki, while it was found between 1.43 (PLs of liver) and 2.52 (NLs of muscle) in C. sieboldii. C. baliki was the excellent species in terms of polyunsaturated fatty acid (PUFA) levels in TL (43.92% in muscle) and PLs (52.94% in muscle) and C22:6 n-3 amounts (docosahexaenoic acid; DHA) were responsible for these high percentages. These results suggest that Capoeta species investigated have high nutritive value in terms of polyunsaturated fatty acids for human nutrition.

Numerous recent publications have compared different cultivars of broccoli and different cultivation conditions suggesting that great variations in the content of phytochemicals among cultivars are due to genetic, and many environmental factors. The purpose of the present work was the quantification of glucosinolates, phenolic compounds, carotenoids, and antioxidant capacity in the florescences of 13 genotypes from freshly harvested broccoli grown under uniform agroecological practices. The present results showed a significant variation in the level of bioactive compounds and consequently potential health benefits of broccoli (total glucosinolates 12.04–22.48 μmol g−1 d.w., the total phenolic content 15.54–26.92 mg g−1 d.w., total carotenoid content 0.19 mg g−1–0.46 mg g−1 d.w.). Studied cultivars were different in the level of the individual bioactive compounds, although some cultivars had higher content of all three analysed bioactive compounds such as Marathon, Ironman and General cultivar. In addition, these three cultivars showed excellent marketable properties and we choose them for the further breeding program in order to study variation among bioactive compounds in more details.

Dietary fibres (DFs) are essential components of the balanced diet. Even though the adequate level of their consumption can be ensured from several natural (e.g. fruit, vegetables, legumes) and ‘artificial’ sources (e.g. functional foods), the consumed levels are below the recommendations. To analyse the Hungarian and Romanian consumers’ knowledge level, their perceptions of the health benefits associated with fibre, as well as the recognition of the potential information sources, a survey questionnaire was conducted with the total of 713 consumers. Results showed that the level of knowledge about DFs was not adequate. Internet was found to be widely used and identified as one of the most appropriate information sources to encourage the consumption of DF. It was a favourable result that three-quarter of the respondents was interested in the topic of healthy food consumption; however, just less than half of them took into consideration the label information during their shopping decisions. To increase the consumption of DF and to support the responsibility and conscious consumer decisions steps must to be done (e.g. education of children, pointing out of the sources). For this purpose, modern information technology and communication channels fitting to the consumers’ cultural and personal particularities can be utilized.

Most of red wine's health benefits are attributed to polyphenols, which can express different biological effects. During ageing process, numerous chemical reactions occur, alternating phenolic composition of wine. Therefore, this paper focused on the influence of ageing on the evolution of wine phenolics (phenolic acids, flavonoids, stilbenes, and anthocyanins). Wines from 4 local grape varieties (Frankovka, Portugieser, Probus, and Rumenika) were analysed after 1 month and 4 years of ageing. Monomeric anthocyanin and total phenolic contents and antioxidative potential in aged wines were also determined. Among tested phenolics, main components in aged wines remained gallic acid (2.16–19.55 mg l−1) and catechin (8.39–37.21 mg l−1). The most prominent changes of analysed phenolic compounds during ageing were observed for p-coumaric acid (from +173.3% to +763.1%) and malvidin-3-glucoside (from +173.3% to +763.1%). Wine from Rumenika variety maintained the highest content of individual phenols after ageing. Additionally, aged wines had very low content of monomeric anthocyanins. Significant correlation (r= −0.93, P<0.05) between total phenolic content and IC50 values in aged wines was also noticed. Obtained results provide useful information about the quality preservation during aging and storage of these products.

Studies were carried out to isolate and screen lactic acid bacteria with probiotic potentials and amylolytic activities from the ruminal ingesta of cow and goat. Ninety isolates obtained from the three abattoirs were divided into the following species: Lactobacillus plantarum, L. fermentum, L. pentosus, L. brevis, L. buchneri, L. collinoides, and Leuconostoc mesenteroides. The isolates were screened for probiotic potentials and amylolytic activities. Four isolates possessed probiotic potentials: L. plantarum CA3b, L. fermentum GA2d, L. plantarum GA1d, and L. plantarum GA3e. Lactobacillus plantarum CA3b, L. fermentum GA2d, and L. plantarum GA3e survived pH 2.5 and 3.5 after 180 min. Lactobacillus plantarum GA1d had the highest tolerance of 82.44% and 71.03% to 0.3% and 1% bile salts concentrations, respectively. Lactobacillus plantarum CA3b hydrolysed 3% starch with an average zone of clearance of 10.0 mm, while L. plantarum GA1d hydrolysed 2% with a zone of 9.5 mm. These two strains also possessed bacteriocin activities against E. coli, and were characterised based on their reactions to pH, temperature, and enzymes treatments. Ruminal ingesta of cow and goat harbour lactic acid bacteria possessing amylolytic and probiotic potentials, which can be exploited in the fermentation of feedstock, conferring health benefits and improved performance to these ruminants.
