Until recently, the only essential nutrient for the acid fermentation of cucumbers which had been investigated as such was sugar. Thus, Fabian and Wickerham (1935) noted that the addition of sucrose late in the fermentation resulted in an increase in the number of acid producing bacteria. However, Jones et al., (1940) and Veldhuis et al., (1941) demonstrated that while the addition of sucrose b...

To quantify the relationships between buffering properties and acid erosion and hence improve models of erosive potential of acidic drinks, a pH-stat was used to measure the rate of enamel dissolution in solutions of citric, malic and lactic acids, with pH 2.4-3.6 and with acid concentrations adjusted to give buffer capacities (β) of 2-40 (mmol·l(-1))·pH(-1) for each pH. The corresponding undis...

Kombucha is a renowned fermented drink for its diverse health benefits. This research aims to evaluate sweetened red ginger extract as an alternative substrate in making kombucha by observing the chemical properties (pH, total acid, sugar, polyphenol, compound profile using LC-MS/MS) and antioxidant activity. Three variables were varied, i.e., concentration (1, 5, 10%), culture (10 20%), fermen...

Kombucha as a tea-based fermented beverage has become progressively widespread, mainly in the functional food market, because of health-improving benefits. As part daily diet for adults and children, kombucha was valuable non-alcoholic drink containing beneficial mixtures organic acids, minerals, vitamins, proteins, polyphenols, etc. The influence specific surface area vessel, inoculum size, in...

The experiment was conducted at Department of Horticulture, College Dr. Balasaheb Sawant konkan Krishi Vidyapeeth Dapoli (MS) during 2020-21 to study the effect post-harvest treatments different chemical and plant growth regulators on physical characteristics sapota fruits cv. ‘Kalipatti’ storage ambient condition. Fast ripening Sapota stage results in their short shelf life which leads deterio...

In this study, we incorporated gallic acid (GA) and salicylic (SA) onto chitosan (CS) using free radical grafting initiated by hydrogen peroxide/Vitamin C (H2O2/Vc) redox system. We characterized the structural properties of GA (CS-GA) SA (CS-SA) derivatives UV–vis absorption, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), nuclear magnetic resonance (NMR), thermal stab...

Canopy shading is a widely used viticultural strategy for mitigating early grape berry ripening caused by global warming. In this study, we covered half of the canopy with black shade cloth from pea-size stage to harvest. fruit zone, treatment (ST) reduced daily average solar radiation about 74.6 % compared untreated control (UC), and significantly temperature. ST leaves were found have lower n...

An acid-titration method for the determination of bicarljonate and titratable acid in the one sample of urine is described. The method needs only one manipulation of the sample of urine, and was devised to simplify routine laboratory methodology. The accuracy and precision of the urinary bicarbonate method during routine laboratory use is comparable to that obtained by using the Van Slyke manom...
