Craft beer production in the United States has been increasing significantly in recent years. As production and participation in the industry increases, so have consumer demands for more beer options. Breweries have met this call with experimentation of ingredients in their beer and also the styles they brew. One such beer, the sour beer, is an example of this experimentation and new product development. Sour beers are a style that differ from most other beers by how they are manufactured. Instead of being fermented with only yeast, both a lactic acid-producing bacteria and yeast are used. With increased competition amongst ...


Development Of Kefir Products Using Aronia Or Elderberries And The Impacts Of Fermentation On The Health-Promoting Characteristics Of Aronia Polyphenols, Xue Du Aug 2018

Development Of Kefir Products Using Aronia Or Elderberries And The Impacts Of Fermentation On The Health-Promoting Characteristics Of Aronia Polyphenols, Xue Du

Electronic Theses and Dissertations

Diabetes is a global health problem. The consumption of dietary polyphenols may help to decrease the risk of type 2 diabetes and slow the progression of diabetic complications. Aronia (Aronia melanocarpa) and elderberry (Sambucus nigra L. ssp. canadensis) fruits are rich in polyphenols and exhibit health-promoting properties, but they are underutilized. Aronia and elderberries are rarely consumed raw due to the astringent mouth feel. New food products are needed to increase their consumption. Kefir, a fermented dairy beverage, was chosen to be the matrix for incorporating berries due to: 1) the protein matrix can help mask the astringency; 2) an ...


Development And Shelf Life Evaluation Of A Novel Fermented Seaweed Sauerkraut Utilizing Commercially Important Maine Seaweeds, Sarah M. Brochu Aug 2018

Development And Shelf Life Evaluation Of A Novel Fermented Seaweed Sauerkraut Utilizing Commercially Important Maine Seaweeds, Sarah M. Brochu

Electronic Theses and Dissertations

Fermented vegetables can provide consumers with important health benefits, particularly due to the presence of probiotics. These fermented products have gained popularity with American consumers over the past decade. Therefore, a lacto-fermented seaweed sauerkraut, containing seaweed and cabbage, was developed to address this trend and to create a value-added seaweed product with extended refrigerated shelf life. The objective of this study was to evaluate the effects of kelp species and seaweed incorporation level on the fermentative success, microbial safety, consumer acceptability, and refrigerated shelf life of seaweed sauerkraut for 60 days post inoculation.

Six treatments with varying levels (25%, 50 ...
