Identify chemical reactions involved in food preparation and preservation. Explain how these processes impact life and the environment. Discuss how their rates can be controlled to either enhance their beneficial effects or lessen their adverse effects.
At least 70 people attending a national conference became ill with what appeared to be food poisoning. Three hospitals in the area treated and released 48 attendees who complained of nausea and vomiting; others with similar symptoms were hospitalized overnight. A health official noted that all the patients had eaten brunch or lunch at the same hotel. The hotel’s lunch menu included roast chicken, roast beef, and a vegetable pasta dish. Because some of the people who became ill were vegetarian, there was particular interest in determining whether the pasta dish might be contaminated. At the time of the report, health officials were still looking for the source of the outbreak. The hotel was cooperating in the investigation and had voluntarily halted food service for the time being. Explain why you might consider this problem important enough to investigate. Give at least three reasons for investigating and explain suitable recommendations and interventions for controlling the problem…

In gastroesophageal reflux disease (GERD), often called acid reflux, stomach acid flows backward from the stomach into the esophagus. Repeated episodes in which esophageal pH goes below 4.0, considered clinical acid reflux, can result in bleeding ulcers and damage to the esophageal lining. The data in the Figure, from a patient with GERD, show esophageal pH during a sleeping reflux event. How many minutes does it take to go from the peak of the reflux event (when pH is most acidic) to when the reflux event is over? Source: Based on T. Demeester et al. 1976.
