To test the carotene stability in dehydrated alfalfa meal (pellated) which was treated with ethoxyquin (antioxidant) and stored under an inert gas until sent from the dehydrated feed manufactures Co., samples were divided into equal amount. One lot was stored at 2〜3℃, the othes were stored under room temperature during the storage test period. As shown in the tables, carotene retention was not similar in the storage samples. The results showed that the dehydrated meal stored at room temperature retained noly 49 per cent of the original carotene. But samples which stored at low temperature showed better retention of carotene. And the difference of carotene retention was about 12 percent at the end of the test period. The analytical data obtained for the dehydrated alfalfa meal samples show definite trends that may be related to storage temperature even though ethoxyquin was added. The data obtained in this study strongly suggest that the storage temperatures are important factor in the retention of carotene in dehydrated meal even when it is treated with the stabilizer, ethoxyquin.
