Abstract

The invention discloses instant orange slices and a preparation method thereof. The preparation method comprises steps as follows: (1), an orange is disinfected and subjected to color protection in an aqueous solution of citric acid and sodium hydrogen sulfite; (2), the orange subjected to color protection is sliced and subjected to deastringency in an aqueous solution of edible salt and citric acid; (3), the orange slices are boiled for 20-60 minutes in a mixed solution of white granulated sugar, high fructose corn syrup, vitamin C, citric acid and edible salt and then is left to stand for 12-24 hours; (4), the orange slices left to stand are baked for 2-5 hours in a hot air drying box with the temperature ranging from 40-60 DEG C. The instant orange slices are in light yellow, have moderate rigidity and a good taste, is sour and sweet, has a refreshing flavor specific to oranges and is convenient to eat, nutritional and healthy. The technological operation is simple, the cost is low, and engineering industrialization is easy to realize.
