Use of ascorbic acid tablets to enrich milk for infant feeding.

Summary Since the amount of reduced ascorbic acid contained in milk is insufficient to meet the nutritional needs of a nursing infant, a supplementary source is required. Frequently orange purchased from the local store is used as a source of ascorbic acid. Such orange juice contains an uncertain and variable amount of ascorbic acid. Tablets designed to disintegrate rapidly provide a convenient means for adding to the infants nursing bottle of milk a standardized, uniform amount of ascorbic acid sufficient to meet daily nutritional requirements.

The influence of storage on the fatty acid content of cod liver oil

SummaryA study has been made of the change of fatty acid content of cod liver oils during storage. Thirty oils varying in acid content from 0.38% to 20.88% were procured in the open market. They represented three types of oils—medicinal, animal feeding and industrial oils. The samples of oil were stored at room temperature, in the dark, in three-fourths filled, four-ounce, amber, cork-stoppered bottles. The acid content was determined twelve times during a period of forty-two months. The acid content of each oil increased. The amount of increase varied from 7.42% for a sample of industrial oil with an initial acid content of 16.45% to 84.80% for a sample of animal feeding oil with an initial acid content of 0.99%. In general, the cod liver oils with initial high acid content showed a lower percentage increase in free fatty acids than oils with a low initial free fatty acid content.
