A Proposed Method of Test for Spoilage of Fruits and Vegetables

摘要

This document is intended to provide all procedures and background needed for testing fruits and vegetables for determination of spoilage progression during storage. This method of testing was developed for research into the effect ofhousehold refrigeration storage conditions on the shelf life of fruits and vegetables (Pate and Brehm-Stecher 2005). Instructions start with the procurement of the produce and sample preparation prior to placement within the environmental chamber. Data collection procedures used throughout the experiments are specified and a checklist for visually identifying physical attributes of "spoilage " and "freshness " are developed. Procedures for the counting of microorganisms and data collection are explained step-by-step.
