冷冻披萨无疑是食品行业增长最快的单一产品。该产品总体上是高度可接受的，特别适用于学校午餐计划。因此，这项工作不仅要确定冷冻披萨的可接受性，还要确定其营养价值和储存方法，以最大限度地保留有价值的营养。结果表明，少量添加营养添加剂可显著提高冷冻披萨的营养价值，因此通常7盎司（200克）的披萨将提供每日膳食所需蛋白质、维生素B1、铁和钙的一半。RDA水平为10%至25%时，许多其他营养素都可用。冷冻保存3个月后，可接受性没有损失，6个月后，可接受性和营养价值只有轻微损失。 引文:加利福尼亚州洛杉矶ASHRAE Transactions第86卷第1部分

Frozen pizzas are undoubtedly the most rapid single growth item in the food industry. The product is highly acceptable generally, and specifically for use in the school lunch program. This work was therefore undertaken to determine not only the acceptability of frozen pizzas but also their nutritive value and methods of storage to maximize retention of valuable nutrients. The results indicate that small additions of nutrient additives substantially improve nutritive value of frozen pizzas so that the usual 7-oz (200 g) serving will provide half of the daily dietary requirements of protein, vitamin B1, iron, and calcium. Many other nutrients are available at RDA levels of 10 to 25%. No losses in acceptability were observed after frozen storage of 3 months, and only slight losses after 6 months of both acceptability and nutritive value.
