Sucrose Concentration And Fermentation Temperature Impact The Sensory Characteristics And Liking Of Kombucha, Gil Cohen Nov 2023

Sucrose Concentration And Fermentation Temperature Impact The Sensory Characteristics And Liking Of Kombucha, Gil Cohen

Masters Theses

Kombucha is a fermented tea beverage consumed for its probiotics and functional properties and has a unique sensory profile driven by the properties of tea polyphenols and fermentation products, including organic acids. Fermentation temperature and sucrose content affect the fermentation process and the production of organic acids, yet less is known about the impact on the sensory profile and consumer acceptance. Thus, we aim to examine the impact of sucrose concentration and fermentation temperature on sensory attributes and liking. For this study, kombucha tea was fermented at three different concentrations of sucrose and fermented at two temperatures for 11 days. …


Sucrose Concentration And Fermentation Temperature Impact The Sensory Characteristics And Liking Of Kombucha - Data, Gil Cohen, David A. Sela, Alissa A. Nolden Aug 2023

Sucrose Concentration And Fermentation Temperature Impact The Sensory Characteristics And Liking Of Kombucha - Data, Gil Cohen, David A. Sela, Alissa A. Nolden

Data and Datasets

In this data set we can see the pH, brix, and titratable acidity measurements in triplicate, as well as the sensory study data. The kombucha batches were combined prior to sensory testing and measured for their combined titratable acidity as well.


Effects Of Tempeh Fermentation On Soy Free And Bound Phenolics: Release, Transformation, And Stimulated Production, Amadeus Driando Ahnan Dec 2020

Effects Of Tempeh Fermentation On Soy Free And Bound Phenolics: Release, Transformation, And Stimulated Production, Amadeus Driando Ahnan

Doctoral Dissertations

The fermentation of tempeh, a traditional source of protein originated in Indonesia, has been reported to enhance the health-promoting potentials of various grains, legumes, and beans. Tempeh fermentation on soybeans can modulate the bioavailability of phenolic compounds, particularly isoflavones, bioactive compounds that have been found to be protective against lung, prostrate, and colon cancers. However, the mechanism of the protective benefits was unknown. Using whole-food and in vitro models, this study addressed this research gap by investigating the effects of tempeh fermentation using various cultures on the compositions of soy free, bound, and minor phenolics, as well as their antioxidative, …


Lactic Acid Bacteria Mediated Phenolic Bioactive Modulation From Fruit Systems For Health Benefits, Chandrakant Ankolekar Feb 2013

Lactic Acid Bacteria Mediated Phenolic Bioactive Modulation From Fruit Systems For Health Benefits, Chandrakant Ankolekar

Open Access Dissertations

Chronic oxidation linked diseases are on a rise and are one of the leading causes of death globally. Epidemiological evidence increasingly points towards consumption of fruits and vegetables as a preventive way to manage early stages of chronic oxidation linked diseases. Oxidation linked diseases are caused by excessive reactive oxygen species (ROS) generated by a disruption in cellular antioxidant homeostasis due to an overload of calories combined with stress, no excerise and a diet low in antioxidants. Phenolic compounds can not only act as antioxidants but also stimulate the activities of antioxidants enzyme through protective pathways which can help modulate …
