摘要: 'Tuogu' and 'Bingtang' plums display unique textural responses to salt curing, manifesting in volume reduction, surface wrinkling, and alterations in color and texture, alongside ongoing material exchange. Over a seven-day salting period, 'Tuogu' plums lost 14.9 % of their moisture, compared to 'Bingtang' plums' 24.8 %, with salt permeability rates of 5.0 % and 5.2 %, respectively. Cuticle analysis revealed that the dominant component of the cutin monomers in both fruits was fatty acids, accounting for over 90 %, while the wax composition was predominantly very long-chain alkanes and triterpenoids, also constituting over 90 %. 'Tuogu' plums, with their rich waxes and dense, thick cuticle, showed enhanced barrier properties against material exchange, whereas 'Bingtang' plums, with their abundant cutin monomers, exhibited increased elasticity and material exchange capacity.
