Food Science and Human Nutrition Publications

Agricultural water is a known vector for the transfer of foodborne pathogens onto fresh produce. Development of pre-harvest and post-harvest microbial profiles of agricultural water used by fresh produce growers, processors, and holdings is a requirement under the Food Safety Modernization Act Produce Safety Rule. One of the United States Environmental Protection Agency (US EPA) approved agricultural water testing methods is US EPA Method 1603, which requires no greater than a 6-h time frame between the collection of the water sample and initiation of analysis. This 6-h timeframe is unrealistic for many produce growers due to there being few laboratories ...


Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert Sep 2019

Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert

Food Science and Human Nutrition Publications

Wines produced from red interspecific hybrid grape cultivars (Vitis spp.) typically have lower tannin than wines produced from vinifera cultivars, which can be attributed to the lower concentration of tannins and higher concentration of tannin binding proteins of interspecific cultivars. Tannin in wines produced from hybrid cultivars could potentially be increased by blending hybrids with vinifera. We hypothesized that blending of grapes prior to fermentation (cofermentation) should result in final wine tannin concentrations lower than wine tannin concentrations predicted from the individual components due to protein-tannin binding, but that this effect should be absent from monovarietal wines blended post-fermentation. To ...
