Title
Anthocyanin decolorisation and its role in lychee pericarp browning
S Underhill; C Critchley Australian Journal of Experimental Agriculture 1994. doi:10.1071/ea9940115
Other claims from this paper (12)
- Observation Pericarp colour deteriorated rapidly during ambient and high temperature storage, with uniform browning.
- Association Tissue browning was proportional to pericarp desiccation rate.
- Association Visual colour and Hunter a values were inconsistent with total anthocyanin concentration.
- Association Hunter a values correlated more strongly with pericarp homogenate pH.
- Intervention effect External pH altered pericarp colour.
- Intervention effect Acidification increased pericarp redness.
- Intervention effect Alkaline treatment caused discoloration.
- Observation Both pH colour responses were reversible and independent of anthocyanin synthesis and degradation.
- Observation No browning was observed in anthocyanin-containing mesocarp.
- Intervention effect Acidification of brown tissue significantly increased redness without anthocyanin synthesis.
- Mechanism Authors suggest pigments progressively decolorised during ambient storage, possibly due to pH changes.
- Mechanism Authors suggest browning became visible and enhanced once pigments became colourless.
