CryoEM composition regarding mycobacterial cytochrome bd unveils a couple of o2 access channels

In addition, it could be considered as a natural antioxidant source in formulating functional yoghurt either in industrial and/or small industrial scale.Bingol is a famous region for honey in Turkey. The amount of phenolic substance is also considered important for the anticancer, antioxidant and antimicrobial properties of honey. Anticancer activity of honey extract was determined as the most effective dose of 1 mg/mL using the WST1 anti-proliferation kit in the PC-3 cell line. Total phenol content were found between 476.09 ± 1.67 and 865.22 ± 3.57 mg GAE/100 g honey, total flavonoid content 41.67 ± 0.25 and 1249.74 ± 0.85 mg QE/100 g honey, total phenolic acid content 0.74 ± 0.21 and 58.35 ± 1.56 mg SA/100 g honey, β-carotene 1.71 ± 0.06-3.61 ± 0.08 mg/kg honey, lycopene content 0.89 ± 0.03 and 3.41 ± 0.08 mg/kg honey, respectively. Percent removal of H2O2 was determined in the range of 69.79 ± 1.24 and 75.37 ± 1.72 at 10 mg/mL. DPPH percentage removal for 200 mg/mL was between 69.79 ± 1.24 and 75.37 ± 1.72. Phenolic compounds in honey extract were determined as gallic acid, caffeic acid, syringe acid, chlorogenic acid, p-coumaric acid, ferulic acid, catechin, quercetin, chrysin using HPLC analysis. The honey extracts were tested on Gram(+) and Gram(-) bacteria and yeast and their antimicrobial effects were determined. As a result, phenolic honey extraction, performed from five loci from the region of interest, showed anticancer, antioxidant and antimicrobial properties, and can be used as a functional food additive to replace synthetic counterparts.The objective of the present study is developing a new technique for the preservation of natural cheese by the use of an edible biofilm based on sodium alginate in order to evaluate the effect of the essential oils (O. basilicum L, R. officinalis L. A. herba alba Asso. M. pulegium L.) incorporated in the film on the oxidation stability, microbial spoilage, physicochemical characteristics and sensory criteria. The cheese samples coated with sodium alginate incorporated by the oils showed moderate stability in terms of oxidative stabilities of proteins and lipids during storage. In addition, poor microbial growth (total aerobic mesophilic flora, yeasts and fecal coliforms) was observed in cheese samples coated with biofilm, also, the growth of Staphylococci Salmonella and Molds for all types of cheese were completely inhibited. Additionally, it was observed that the biofilm coating reduced the weight loss and hardness of the cheese comparing with the uncoated sample. The results of sensory analysis revealed that uncoated cheese, coated with sodium alginate and sodium alginate composed of oil of O. basilicum were the most preferred by panelists, in comparison with others. Therefore, it was concluded that this technique of coating cheese with edible film activated with essential oils is preferred and favorable by virtue of the effect of oils preserving the cheese without seriously affecting their organoleptic properties.This study aimed to produce beverages using extract or infusion of Hibiscus sabdariffa leaves with cupuassu pulp. The blended drinks with cold or hot extraction were formulated using the response surface methodology. Moreover, the physico-chemical and sensory stability of these beverages was performed for 180 days. The conditions production for beverage leaf extract were 28% leaf extract, 72% cupuassu pulp, and 14°Brix. For beverage leaf infusion, were 37% leaf extract, 63% cupuassu pulp, and 13°Brix. Comparing the two beverages, the polyphenolic compounds and the antioxidant activity (ABTS and DPPH) were higher in the blends produced with leaf extract. Thus, the cold extract provided better extraction of these components in the leaves. During storage, pH, reducing and total sugars and soluble solids of blends increased linearly (p  less then  0.05). Nevertheless, vitamin C, polyphenolic compounds, and the antioxidant activity reduced linearly (p  less then  0.05). The sensory acceptance of blends containing leaf extract, in the hedonic scale, all sensory attributes were positively scored up to 135 days. At 180 days, the acceptance reduced for rejection. The blended beverage containing leaf infusion had all sensory attributes positively scored up to 90 days, with a rating between 6.27 and 7.42. At 135 and 180 days, the values were in the indifference region of the hedonic scale or acceptance region. click here Therefore, the blend with leaf infusion maintained better acceptance during storage when compared to leaf extract beverage. Thus, the blended beverages had good nutritional value and sensory acceptance and were acceptable for up to 135 days.Diverse researchers have considered by-products of food and agricultural processing industries as a source of antioxidants. Tamarind (Tamarindus indica) is a leguminous tree, native from tropical Africa bearing edible fruit. The fruit is composed of 30% pulp, 40% seed, and 30% pericarp. Currently, tamarind pericarp is a waste from tamarind processing (approximately 54,400 tons of pericarp in 2012 worldwide) and is contributing to environmental contamination. This research aimed to determine the effect of maceration, microwaves, and ultrasound on the increase in the antioxidant availability in tamarind pericarp and its incorporation as a functional ingredient in cookies (5 and 10% substitution). Antioxidant content, antioxidant activity, proximate, and sensorial analysis of the cookies were conducted. The microwave method was the best pretreatment compared with sonication and maceration since it showed 1.3-fold higher amounts of phenolic compounds and 1.2-fold higher antioxidant capacity. The 10% substitution of tamarind pericarp powder in cookies, significantly increased the fiber content (four-fold) and phenolic compounds content (2.6-fold) and the product presented good acceptance in a sensorial test. Thus, tamarind pericarp powder could be considered as an antioxidant and fiber source and could be used as a functional ingredient in food products.Shelf-life of paddy straw mushroom could be extended to 3 days by pre-cooling mushrooms in air at 14 °C for 2 h followed by packing in 75 µ thick high impact polystyrene punnets with 1.2% perforations as primary package and subsequently stored in expanded polystyrene (EPS) cabinet as secondary package. The EPS cabinet has been designed for transportation of mushroom with ice as cooling aid to maintain the optimum storage temperature. Temperature profile inside the cabinet was studied under no-load and full-load condition. The temperature inside the cabinet with 6 kg pre-cooled paddy straw mushroom (packed in 24 number of punnets @ 250 g mushroom per punnet having 1.2% perforations) and 6 kg ice in the partition chamber, was maintained at optimum storage temperature of 15 ± 2 °C (92 ± 1% RH) up to 18 h. Results of the study suggest that the technology could be successfully adopted by the paddy straw mushroom growers and traders for storage, transportation and marketing for loss reduction and higher return.
