Energy, Protein, Mineral and Water Content of Food Items.

Abstract

Methods used to determine the energy, protein, mineral, and water content of prepared food items that composed the diet for five divers involved in a biomedical study lasting 30 days which included nutrition in a high pressure helium-oxygen environment are described. Moisture content of food items was determined by a gravimetric procedure, energy by oxygen bomb calorimetry, nitrogen by a semimicro Kjeldahl procedure, and sodium and potassium by atomic absorption spectrophotometry. Approximately 300 food items were analyzed in order to calculate the energy, protein, mineral and water intake for the hyperbaric nutrition balance study.
