Storage Techniques

Storage Techniques

Non-chemical scald control and prevention of internal browning are major focusses of the evaluation of storage technologies and protocols. On the browning front, recent research by Dr Elke Crouch and Heleen Tayler showed that stepdown cooling has considerable potential in preventing or reducing internal browning incidence. A major outcome of research in this theme is the development of protocols to prevent or reduce the incidence of disorders and to maintain fruit quality.
