Casimiroa edulis as a food
Casimiroa edulis is primarily eaten fresh either on its own or added fresh to other foods as due to its properties, White Sapote has proved unsuitable to canning or freezing (Morton 1987). Casimiroa edulis is a sweet fruit containing 27% sugars and has been compared to custard, peach or banana in flavour (University of Connecticut 2017). It is often combined with milk to produce ice-creams or milkshakes and is rich in vitamin A and C (University of Connecticut 2017). Apparently it can be made into a spread similar to marmalade (Morton 1987).
Potential as a commercial crop in Australia
Due to its high sugar content (University of Connecticut 2017) I think white sapote has potential as market sold fruit in Australia as most people enjoy sweet fruit. Unfortunately due to its inability to endure chilling long term storage of White Sapote fruit is problematic with a refrigerated life of only two weeks (Morton 1987). Ideally the fruit needs to be picked serveral weeks before ripe with a short piece of stem still attached (similar to a peach) to extend shelf life (California Rare Fruit Growers 2017). Heavy frost and low temperatures will damage White Sapote plants and fruit which is why it may only currently be grown commercially in northern New South Wales.
