Abstract. Freeze‐dried peas were compressed 4‐fold and subsequently rehydrated to virtually their precompression characteristics. Histological studies showed that conventional processes of freezing and freeze‐drying result in considerable disruption of cell walls. Contrary to what was anticipated, compression forces of 1000–2000 psi resulted in only a slight increase in breakage of cell walls. However, no correlation was established between cell disruption or texture and increasing compression force. A study of the effects of plasticizing moisture and compression force enabled optimization of processing conditions resulting in compressed peas which can be reconstituted to virtually their precompression characteristics.
