Kombucha is a fermented tea beverage which is traditionally prepared by fermenting sweetened black or green tea (Camellia sinensis L.) with symbiotic consortium of bacteria and yeasts (SCOBY). In this study, lemon balm (Melissa officinalis L.) was used as the only nitrogen source for kombucha fermentation. During the seven-day fermentation process, pH value, titratable acidity (TA), total pheno...

Anti-ulcer activity of methanolic extract of Withania somnifera (Ashwagandha) and its action against stress plus pyloric ligation induced gastric ulcer in rats has been reported. Treatment with Withania somnifera extract (100 mg/Kg/day p.o.) for 15 days significantly reduced ulcer index as compared to control group. Extract also significantly reduced volume of gastric secretion, free acidity an...

Objective: To evaluate the antiulcer activity of chloroform extract of Cedrus deodara and Pinus roxburghii wood (Cd C and Pr C, respectively). Methods: Cd C and Pr C at doses of 50 and 100 mg/kg were given orally to fasted rats and ulcers were induced by pyloric ligation and ethanol. Number of ulcer, ulcer score, ulcer index, percentage ulcer inhibition and tissue histology were measured in bot...

The postharvest treatments included control, low temperatures (14 and 18°C) and plastic bags with or without perforations. Changes in different physico-chemical characteristics of fruits were studied during storage. The two factor experiment was laid out in completely randomized design with three replications of 10 fruits. Among the physico-chemical parameters, colour, firmness, total weight lo...

the performance of msu-s and its forms modified with phosphotungstic acid (hpw) and nickel (ni) for the desulfurization and denitrogenation of model diesel fuel were studied. according to the results of the characteristic tests (n2 adsorption-desorption, xrd, sem, and nh3-tpd), heteropoly acid incorporation causes higher acidity along with a negligible loss of structural aspects, while ni impre...

The effect of processing on the biochemical contents of Acanthus montanus leaves was investigated. The moisture, crude protein, lipid, fiber, ash, and total carbohydrate contents of the raw vegetable were 59.15, 1.85, 2.32, 3.76, 2.04, and 34.65 g/100 g, respectively. The saponin, alkaloid, tannin, flavonoid, phenol, and anthocyanin contents of the raw vegetable were 5.35, 4.04, 1.10, 3.53, 2.8...

1. Initial glycogen levels in the liver were found to be significantly higher than in the kidneys of the two species studied. The glycogen levels in kidney were however considerably higher than in some mammalian species. 2. Total reducing capacity, true glucose, saccharoid fraction and titratable acidity increase gradually with concomitant decrease in the glycogen levels when liver and kidney h...

BACKGROUND High consumption of nonalcoholic beverages is one of the causes of dental erosion. Annual consumption of beverages in Iran is 48 LPCY (Lit per capita per year) that is equal to 144 bottles per capita in year and is relatively a high rate. Taking this into consideration, the present study was planned to determine the pH and fluoride content of beverages consumed in Kerman, south east ...

Black currant berries contain many biochemical compounds with proven or potential human health benefits. We studied the content of total and single polyphenols, ascorbic acid, soluble sugars, and titratable acidity for two advanced selections and three cultivars of black currant at two distant locations in Sweden (south: 56°06'N; north: 65°21'N) over a 3 year period. Regression analyses reveale...

In this study, 3 different spice mixes were added just after blanching to mozzarella cheese produced by high moisture production method. The dough was kneaded and filled into to fibrous cases. After filling process, cheeses were stored for 28 days at 4 °C and 85 % of relative humidity. The following characteristics were measured: color parameters, milk acidity, total dry matter, maturation inde...
