Abstract
AbstractThe effect of various levels of moisture content of dehydrated potato on the relationship of ‘total’ and ‘free’ sulphur dioxide contents has been studied and the influence of these relationships on the development of non‐enzymic browning has been noted. The use of ‘in‐package’ desiccants to reduce moisture contents reduces the rate of loss during storage of the total sulphite previously added to the potato. Free sulphur dioxide is also found to decrease during storage until the moisture content reaches a critical low value. At or below this moisture level, loss of ‘free’ sulphur dioxide is prevented, and in fact at moderate temperatures of storage it may actually increase. It is suggested that for potatoes of the variety and condition tested, the onset of non‐enzymic browning would be delayed beyond 52 weeks by ensuring that ‘free’ sulphur dioxide levels were maintained at not less than 250 p.p.m.
