    Notes: Unit operations in several commercial processing operations of frozen potato products were evaluated regarding their effects on the protein and water-soluble vitamin composition of the products. The investigation included processing lines for French fries and preformed patties. Overall retention values ranged from a low of 53% for ascorbic acid in preformed patties to a high of 90% for vitamin B6, also in preformed patties. With the exception of the case of ascorbic acid in preformed patties, water blanching was the chief contributor toward the reduction of nutrients. The effects of the other unit operations were statistically nonsignificant. Retention values with small cut French fries were lower than those of the large size cuts. Retention values were significantly greater with steam blanching than with water blanching.

    Notes: A comparative analysis of raw and cooked tuber peel and flesh was performed. Whether raw or cooked, and regardless of the cooking methods used tuber peel contained significantly higher amounts of ash, crude fiber, protein and riboflavin but less thiamine than the corresponding flesh. Raw peel contained less ascorbic acid and niacin, more folic acid than and about the same amount of vitamin B6 as the corresponding tuber flesh. However, the relative amounts of these four vitamins changed depending on the cooking method used.

    Notes: The major US potato varieties grown in various locations were analyzed for their contents in water-soluble vitamins both at harvest time and during subsequent storage. Compositional ranges of each vitamin were quite large. Only a few varietal and location effects were detected. In the case of ascorbic acid, what appeared to be a location effect could likely have been the result of differences in harvest time of the samples. Prolonged storage had little overall effect on thiamine and riboflavin. It resulted in a sharp initial decrease in ascorbic acid, significant decreases in niacin and folic acid, and a significant and large increase in Vitamin B6. Storage temperature in the range of 38°-45°F did not affect the vitamin composition, nor did reconditioning of the tubers at room temperature following cold storage.

    Notes: Unit operations in several commercial potato dehydration plants were evaluated to determine the direct effects on protein and vitamin content of the product. The investigation included processing lines for potato granules and flakes as well as dehydrated slices and dices. Protein and vitamin retentions, in general, were lowest at any point where potatoes were exposed to high temperature for prolonged periods of time. The addition of sulfites had a deteriorating effect on thiamine resulting in losses of up to 96% for this vitamin. The other vitamins most severely affected were ascorbic acid and folic acid with retention values as low as about 40%. In the granule process, vitamin retention was most severely affected during the mixing and mashing steps. During the flake operation, water blanching and the drum drying operation resulted in the greatest reduction of retention values. Thiamine retention was a relatively high 64% during the production of potato flakes. The manufacture of dehydrated slices and dices showed the lowest retention values of all the dehydrated potato products investigated.
