Preservation of fruits and vegetables by freezing in refrigerated locker plants
The purpose of this bulletin is to provide authentic information on the selection, preparation and utilization of fruits and vegetables preserved under frozen food locker systems in Iowa. The recommendations are based on investigations under locker plant conditions conducted over a period of 4 years by the Iowa Agricultural Experiment Station. In order that the products would be comparable to those obtained by using ordinary household equipment, preparation and processing was done on a small scale in a kitchen laboratory to simulate home conditions.2 Careful attention was given to details of necessary measures preparatory to freezing as well as to subsequent procedures. The methods herein described have been found to yield frozen products of excellent quality. The information is not intended as a guide for the commercial packing of frozen products. It is applicable most specifically to Iowa grown fruits and vegetables.
