ABSTRACT: In recent years, the consumption and importance of functional foods have increased. Functional foods have therapeutic effects beside their nutritional importance. Probiotic foods and enriched dairy products are among the most important functional foods, especially because of their health promoting effects. Therefore many studies have been published around the presence and the role of probiotics and their viability in dairy food such as yogurt, cheese and ice cream. The focus of this article is to review the application of probiotic microorganisms in dairy products and methods for increasing their viability in dairy food products from Iran.

ABSTRACT: Objective: To research the antibacterial effect of deionized water and ethanol-water extracts from the dried flowers used in Guangdong traditional soup on 7 kinds of familiar intestinal pathogenic bacteria. Methods: We selected 8 types of dried flowers most commonly used in making Guangdong traditional soup, including Rafflesia arnoldii, Bombax ceiba, Dolichos lablab, Pueraria lobata, Flos buddlejae, Lonicera japonica, Flos sophorae and Cordyceps militaris. Seven target bacteria were chosen from usual intestinal pathogenic agents, which included Staphylococcus aureus, Escherichia coli, Salmonella typhimurium, Shigella flexneri, Bacillus cereus, Pseudomonas aeruginosa and Staphylococcus epidermidis. Bacteriostasis rate, MIC and MBC were examined to evaluate the dried flowers’ antibacterial activity on these pathogens. Results: Our findings showed that all the samples exhibited potent antibacterial activity. Gram-positive bacteria were generally more sensitive to the tested extracts than Gram-negative ones. Staphylococcus aureus was the most sensitive, while Escherichia coli was the most resistant. The antibacterial activity of Cordyceps militaris was the strongest, and Flos sophorae and Lonicera japonica followed. At the same time, the antibacterial effect of ethanol-water extract was higher than that of deionized water extract. Conclusions: This was the first time to study the antibacterial property of principal material used in Guangdong traditional soup. These results might underline the theoretical foundation for the dried flowers related Guangdong Traditional Soup’s function of adjusting human body’s healthy condition which we thought was in relationship in some extent with mild inflammation of upper respiratory tract and tonsils. The more explicit mechanism of the antibacterial effect should be further studied.

ABSTRACT: Characterization and anti-nutritional composition of unprocessed finger millet (Eleusine coracana) was conducted. The result of the nutritional constituent shows significant amount of lipid and carbohydrate (2.4% ± 0.02, 79.53% ± 0.03) respectively, with the moisture, ash, fiber, protein levels being 11.75% ± 0.06, 2.2% ± 0.02, 1.20% ± 0.05 and 2.92% ± 0.03) respectively using A.O.A.C. method. The result of anti-nutritional analysis in this study shows that cyanide, oxalate, tannin and phytic acid contain (0.44mg/kg, 0.27mg/100g, 0.989% and 0.348%) respectively. The percentage area yield of the saturated and un-saturated fatty acid. The saturated fatty acid Palmitic and steric acid contents are 19.69% and 10.68% respectively, while the unsaturated fatty acid oleic acid contain 12.35%. The mineral composition of the finger millet was determined using AAS.AA-6800 SHIMADZU. Ca, K, Na, Mg, Zn, Fe and Cr where found to contain (174.58, 158.1, 24.372, 20.78, 0.533, 9.64 and1.118mg/100g) respectively. Vitamin B6, B3, B1, B2 and E are 167.7, 11.24, 332.24, 125.66 and 60.23mg/100g respectively. Maximum utilization of the potential of the millet is limited by the presence of these anti-nutrients. This result shows that the anti-nutrients of the unprocessed finger millet can hinder the absorption of the nutrients.

ABSTRACT: The anti-oxidant property of various parts of Lagenaria siceraria and its derived fractions were investigated by various assays. Among them crude peel extract showed highest radical scavenging and reducing power activity. Ethyl acetate fraction demonstrated most active due to its highest radical scavenging activity and phenolic content. Twenty seven phenolic compounds were identified from LCMS/MS analysis of EAF. Methyl apigenin, acacetin, thymol, dicaffeoylquinic acid, phloridzin, isorhamnetin-3-O-hexoside and rosmarinic acid were identified for the first time. Thus bottle gourd peel being potent antioxidant could be used for prevention of those diseases where oxidative damage has been implicated. Hence a simple, biocompatible, eco-friendly method for the synthesis of gold nanoparticles (NP) was developed using bottle gourd (Lagenaria siceraria) peel extract (BGPE) monitoring ultraviolet-visible spectroscopy, dynamic light scattering (DLS) and atomic force microscopy (AFM). The gold NPs had a face-centered cubic structure having size range 40-50 nm with spherical morphology revealed by X-ray diffraction (XRD). These nanoparticles exhibited good anti-cancerous activity in a concentration dependent loss of survival in p53 mutant A431 skin carcinoma cells. The developed eco-friendly method for the synthesis of biocompatible gold NPs utilizing bio waste could prove a better substitute for the physical and chemical methods for biological applications.
