ABSTRACT
These observations serve primarily as an additional item to the evidence which is being accumulated concerning vitamins and the food value of ice cream.
- From the data presented in this paper it is concluded that an irradiated ice cream mix, prepared from winter cream, heals rickets in the white rat, whereas the non-irradiated product of the same batch of ice cream, fed at a maximum level of 8 per cent of the ration, does not produce a healing.
- A variation of the temperature of the product during irradiation between 15.5° and 62.5°C. (60° to 145°F.), does not affect the activity of the material.
- Freezing and low storage temperature do not affect the antirachitic value of irradiated ice cream for at least two months.
- A definite correlation was not found between the inorganic blood phosphorus level and the degrees of healing as expressed in using the Shipley line technique, there being only a general accord between the two observations. There is no agreement between the results of the Shipley line test and the percentage of bone ash.
