ABSTRACT
Dairy departments in the provincial and state colleges and universities in Canada and the United States, and a research agency of the USDA, were surveyed relative to obtaining information concerning the butter research and testing activities presently under way. Returns from 52 respondents revealed that 14 research stations are presently engaged in research studies on butter or butterfat, and ten stations perform some type of testing service for butter-manufacturing plants. This report summarizes the information obtained relative to the butter research and testing activities at the various stations and also gives suggestions for further research.
COMMENTS
A continuous buttermaking machine suitable for processing plastic cream into butter has been designed and built at Alberta. Saskatchewan reported an increase in one-half cent per pound margin due to increased curd in unwashed as compared with washed butter. No difference in keeping quality was observed between the two types of butter. Similar observations relative to keeping quality were made at Iowa.
