Influence of the storage period before and after SO2 treatment on skin colour, fruit decay and sulphur residue levels in litchis.

Fruits of the cultivars HLH Mauritius and Red McLean (Madras) were held at 21 deg C for 0.5, 2, 4, 18 or 30 h prior to SO2 treatment and for 1, 2, 4, 12 or 48 h afterwards. There were no significant differences in skin colour or incidence of postharvest decay between the holding treatments when the fruits were assessed after 30 days of storage at 2 deg . However, holding for more than 18 h at room temperature resulted in significant loss of moisture and firmness. Sulphur residues in the fruit flesh after storage exceeded the permissible level of 10 p.p.m. when fruits had been packed in polyethylene bags, but were at acceptable levels in open-packed fruits. The eating quality in general was good for open-packed fruits but those packed in the polyethylene bags had an after-taste.
