Excellent

Successful isolation of cavities free from mesophyll cells. Mesophyll cells remain green.

Good

Mostly successful isolation of cavities free from mesophyll cells. Mesophyll cells become brown.

Pectinase

Poor

Mesophyll cells generally remain attached to cavities. Mesophyll cells become brown.

Poor

Mesophyll cells generally remain attached to cavities. Mesophyll cells become brown.

Cellulase

C-1794 (Sigma)

Trichoderma viride

Poor

Cavities lose structural integrity. Lumen contents become brown.

Mesophyll cells become brown.

Cellulase

'Onozuka RS' (Yakult)

Trichoderma viride
