backgrounds and objective: kombucha is a several thousand years old traditional fermented beverage originated from east. while black tea infusion is the common substrate for preparing kombucha, other herbal infusions can be applied for this reason too. common medicinal herbs or even waste herbal materials, like banana peel, could be suitable substrates for preparing kombucha analogues. in this ...

A reliance on self-reported dietary intake measures is a common research limitation, thus the need for dietary biomarkers. Added-sugar intake may play a role in the development and progression of obesity and related comorbidities; common sweeteners include corn and sugar cane derivatives. These plants contain a high amount of ¹³C, a naturally occurring stable carbon isotope. Consumption of thes...

The purpose of this study was determine effects of ingestion carbohydrate-electrolyte beverage drink to improve exercise performance in the heat. Ten male subjects (age 1830 years) were subjected to cycle ergometer at 63.5 ± 3.3% of maximal O2 consumption (VO2max) with a pedal speed of 60 rpm until they became fatigued. They were given a drink of carbohydrate-electrolyte at a concentration of 6...

n-3-polyunsaturated fatty acids and polyphenols are potential key factors for the treatment and prevention of chronic inflammation associated to ageing and non-communicable diseases. The aim was to analyse effects of an almond and olive oil beverage enriched with α-tocopherol and docosahexaenoic, exercise and age on inflammatory plasma markers, and immune gene expression in peripheral blood mon...

Aim: To assess the effect of surface finish and acidic beverage (cola beverage) on hardness fracture toughness zirconia lithium silicate (Celtra press)Methodology: Total n=36 samples reinforced press) plates were divided into two main groups (n=18 glazed n=18 polished samples) then each group was subdivided equal according to immersion solution (artificial saliva & cola beverage). Surface factu...

Self-reported dietary assessment methods can be challenging to validate, and reporting errors for those with lower health literacy (HL) may be augmented. Interactive multimedia (IMM) based questionnaires could help overcome these limitations. The objectives of this investigation are to assess the comparative validity and sensitivity to change of an IMM beverage intake questionnaire (IMM-BEVQ) a...

In this paper, we present a fully integrated and automated lab-on-a-disc for the rapid determination of the total phenolic content (TPC) and antioxidant activity (AA) of beverage samples. The simultaneous determinations of TPC and AA on a spinning disc were achieved by integrating three independent analytical techniques: the Folin-Ciocalteu method that is used to measure TPC, the 2,2-diphenyl-1...

Electrochemistry at the liquid-liquid interface enables the detection of nonredoxactive species with electroanalytical techniques. In this work, the electrochemical behavior of two food additives, aspartame and acesulfame K, was investigated. Both ions were found to undergo ion-transfer voltammetry at the liquid-liquid interface. Differential pulse voltammetry was used for the preparation of ca...

Cocoa beans (Theobroma cacao) are processed into cocoa beverage through fermentation, drying, roasting and grounding of the seed to powder. The mycological quality of 39 samples of different brand of these cocoa – based beverage referred to as ‘eruku oshodi’ collected from 3 different markets in south – west Nigeria was determined by serial dilution using the pour plate method on Potato Dextros...

Production of fermented functional foods containing micronutrients is required for their health beneficial properties. The impact of 11 process variables on vitamin B12 production in a dairy beverage containing propionic acid was investigated. Propionibacterium freudenreichii ssp. shermanii was applied in a 3-l fermentor in the fed-batch fermentation system. The most suitable conditions for...
