Floatation Method for Maturity Testing of ‘Carabao’ Mango
Immature “Carabao” mango does not ripen normally and develop a full mango flavor and aroma. It is also susceptible to internal breakdown when subjected to heat stress. Hence, a very simple nondestructive method of testing the fruit maturity was developed. This method uses salt solution to separate immature fruits from mature ones. Mature fruits tend to sink due to their higher specific gravity while immature fruits float to the surface and are easily removed. Farmers can use this technique to determine readiness to harvest the fruits by gathering at least 12 fruits at random from the whole tree. If 9 fruits (75%) sink in salt solution, then all the fruits can be harvested.
