reduces the cost to about half. It is noted that the most expensive
treatment is with ascorbic acid as twice the concentration of the
ascorbate salts is required. Also, use of sodium ascorbate in lieu of
calcium ascorbate is a potential commercial option as it was quoted
as 10% cheaper than calcium ascorbate but is equally effective in
inhibiting browning. The use of a sodium chloride only dip solution
would markedly reduce the cost to about 3% compared to calcium
ascorbate but it would not achieve a 30 day postharvest life. While
increasing the concentration of sodium chloride above 0.1 mol/l
would further increase postharvest life, 0.1 mol/l is considered the
upper limit to avoid detection of a salty taste by consumers (Li et al.,
2014).
