摘要：
An edible coating for the preservation of pieces of fruit and the manufacturing and application process thereof involves the coating being applied to the fruit by way of a first aqueous solution of an alginate having a high viscosity of above 250 mPa and a low concentration of between 0.05% a 1% by weight relative to the total weight of the first aqueous solution. The coating and process further includes, by way of a second aqueous solution, including a cross-linking agent of calcium ascorbate or calcium lactate, to cause the alginate to gel and including citric acid as antioxidant agent, or a combination of citric acid and sodium ascorbate. The second aqueous solution may also contain malic acid as an antimicrobial agent, where the citric acid and, as the case may be, the malic acid, behave as metal ion chelating agents.
