Red Propolis Extract

Meat has important nutritional characteristics for the diet, being a source of high biological value animal protein, and containing important vitamins for the organism. Ground beef is one of the most consumed meat products, which has an increased surface area, and also a high potential for inadequate storing conditions, which reinforces the relevance of innovative technologies for its preservation, such as the use of propolis – a highly diversified product with antimicrobial and antioxidant activities, seen as a component capable of prolonging shelf life. This study evaluated the effects of the addition of Brazilian red propolis extract to ground beef as a natural antioxidant for 0, 7, 14 and 21 days of storage at a temperature of 7 ºC. The physicochemical parameters of water, protein, lipids and ash content remained stable until the 14th day of storage, while the microbiological ones presented peaks of contamination by Coliforms at 35 and 45 ºC in the same period, however, the absence of Salmonella sp/25g in the meat analyzed, made it suitable for human consumption, thus confirming the effectiveness of using red propolis extract in its conservation.

This article presents the results of a study that examined the effect of Felucen P-2 feed supplement on the growth and development, blood parameters and quality of meat of black African ostriches. The experiment was conducted on two groups of ostriches: the first group received the main diet and the second group received Felucen P-2 added to the main diet. It was found that Felucen P-2 was an effective feed supplement which increased the rate of growth and development of young ostriches. For example, at the age of 90 days, ostriches of the first group had a live weight of 19.15 kg, and of the second group - 20.35 kg; at the age of 120 days, the birds of the first group had a live weight of 29.10 kg and of the second group - 32.05 kg; at the age of 150 days, the birds of the first group had a live weight of 40.35 kg and of the second group - 44.95 kg. In addition, from the age of 120 days, the significant live weight gain was observed. During this period, average daily gains were 332-453 g. The insignificant superiority of ostriches of the second group over the first one by the biological value and meat quality was determined. The ash content in ostriches of the second group was 1.1%, and in the first group it was 0.9%; the moisture content was 75.3 and 77.1, respectively; the protein content was 20.9% and 19.1%, respectively; and the fat content was 2.7% and 2.9%, respectively. In general, meat products had high quality and dietary indicators. Keywords: ostriches, Felucen P-2, daily average gain, meat

The population of grey seals Halichoerus grypus in Canadian waters is currently used as a commercial source of meat for human consumption. As with domestic livestock, it is important to understand the occurrence in these seals of infectious agents that may be of public health significance and thus ensure appropriate measures are in place to avoid zoonotic transmission. This study examined the prevalence of antibodies against Brucella spp., Erysipelothrix rhusiopathiae, 6 serovars of Leptospira interrogans, and Toxoplasma gondii in 59 grey seals and determined by polymerase chain reaction (PCR) the presence of these potentially zoonotic agents in specific organs and tissues of seropositive animals. The presence of encysted Trichinella spp. larvae was also investigated by digestion of tongue, diaphragm and other muscle samples, but none were detected. Seroprevalence against Brucella spp. and E. rhusiopathiae was low (5 and 3%, respectively). All 59 seals tested had antibodies against L. interrogans, but no carrier of this bacterium was detected by PCR. Seroprevalence against T. gondii was 53%, and DNA of this protozoan was detected by PCR in 11/30 (37%) seropositive animals. Standard sanitary measures mandatory for commercialization of meat products for human consumption should greatly reduce the potential for exposure to these infectious agents. However, special consideration should be given to freezing seal meat for at least 3 d to ensure destruction of tissue cysts of T. gondii.

The effect of ultrasonication on the antioxidant and antibacterial properties of Ceylon spinach (Basella alba) extracts (CE) and the shelf life of chilled pork with CE were studied. The CE were ultrasonicated at different power levels (60–100%) for 10–40 min in an ultrasonic bath with the rise of antioxidant activities (p ≤ 0.05) proportional to the ultrasonication time. The additional investigation of antibacterial activities showed that the ultrasonicated extracts (100 mg/mL) could inhibit and inactivate Staphylococcus aureus and Escherichia coli with the optimal condition of 80% power for 40 min. For shelf-life testing, fresh pork treated with the ultrasonicated extracts at 100 and 120 mg/mL had lower values of thiobarbituric acid reactive substances (TBARS) than the control (without dipping). For food safety as measured by the total microbial count, the fresh pork dipped with 100–120 mg/mL CE extract could be kept at 0 °C for 7 days, 2 to 3 days longer than control meat at 0 and 4 °C, respectively. A sensory evaluation using a nine-point hedonic scale showed that fresh pork dipped with 100-mg/mL CE extracts was accepted by consumers. It is suggested that CE extracts can be applied in the food industry to enhance the quality and extend the shelf life of meat products.

Hemp flour from Dacia Secuieni and Zenit varieties was added to bread in different proportions (5%, 10%, 15% and 20%) to improve its nutritional properties. The purpose of this paper was to present the advanced nutritional characteristics of these bread samples. The selected varieties of hemp, accepted for human consumption, met the requirements for the maximum accepted level of THC in seeds. The protein content of new products increased from 8.76 to 11.48%, lipids increased from 0.59 to 5.41%, mineral content from 1.33 to 1.62%, and fiber content from 1.17 to 5.84%. Elasticity and porosity decreased from 95.51 to 80% and 78.65 to 72.24%, respectively. K, Mg, Ca, P, Mn and Fe are the main mineral substances in bread with addition of hemp flour from the Dacia Secuieni and Zenit varieties. The total amount of unsaturated fatty acids in the bread samples with hemp flour ranged from 67.93 g/100 g and 69.82 g/100 g. Eight amino acids were identified, of which three were essential (lysine, phenylalanine, histidine). Lysine, the deficient amino acid in wheat bread, increased from 0.003 to 0.101 g/100 g. Sucrose and fructose decreased with the addition of hemp flour, and glucose has not been identified. The amount of yeasts and molds decreased in the first 3 days of storage. Regarding the textural profile, the best results were obtained for the samples with 5% addition. In conclusion, bread with the addition of hemp flour has been shown to have superior nutritional properties to wheat bread.

Abstract Fruits and vegetables are important sources of nutrients for mankind. Among the various fruits available in Bangladesh, mango occupies a vital place in the human nutrition for its delicious taste and higher nutritious value. In this study, five mango varieties, viz. Fazli, Amrupali, Langra, Gopalbogh and Misribogh, were tested to evaluate the quality of these mango varieties available in Northern Bangladesh. Physiochemical characteristics, including moisture, ash, total carbohydrates, total solids, total soluble solids (TSS), pH, acidity, total sugars and ascorbic acid contents were evaluated. The results showed that there were significant (p< 0.05) differences among mangoes of all varieties for physicochemical parameters. In case of proximate composition, the mango variety Amrupali showed the highest ash content (2.34±0.15) and fat content (1.18±0.13). Protein content (0.94±0.12) and total fiber (2.67%) content was shown to be the highest by Gopalbogh and Misribogh, respectively. The selected mango varieties contained TSS of 12.87~20.55oBrix, pH of 4.45~4.67, titrable acidity of 0.07~0.42%, reducing sugar of 8.40~15.43%, non-reducing sugar of 9.24~10.48%, and total sugarof 18.88~25.12%. The study findings would be helpful for the consumers, dietitian and industry policymakers.
