Background: The functions, food sources, deficiency symptoms, and toxicity symptoms are important for dietetic professionals to know and apply to community, food service, and clinical settings. Purpose: To assess nutrition and dietetic students' knowledge of vitamins and minerals and identify students' strategies for learning and retaining vitamin and mineral information. Methodology: Students from three universities in the western United States were invited to participate in cross-sectional study. Participants completed a brief questionnaire that included multiple choice and short answer questions to assess their knowledge of a representative list of 8 vitamins and minerals. The questionnaire also included free-response questions about …

The influence of high intensity ultrasound coupled with thermoprocessing on the inactivation of Geobacillus stearothermophilus vegetative cells and spores in skim milk powder was explored using response surface methodology and two polynomial models were developed. Optimization of cell reduction (4.8 log) was found to be at 19.75% total solids (TS), 45 °C, and 30 s, while optimization of spore reduction (0.45 log) was found to be at 31.5% TS, 67.5 °C, and 17.5 s. Model verification experiments were performed using common milk powder processing conditions. Results showed the inactivation of cells and spores to be most effective before (9.2% TS, …
