Abstract

The invention discloses low-sugar candied jack fruit strips and a making method thereof. The low-sugar candied jack fruit strips are prepared by using jack fruit strips as raw materials, and are specifically prepared through the following working procedures: using the jack fruit strips as the raw materials, cleaning the jack fruit strips, processing the cleaned jack fruit strips with hot water, pickling the processed jack fruit strips, rinsing the pickled jack fruit strips, desalinating the rinsed jack fruit strips, hardening the desalinated jack fruit strips, rinsing the hardened jack fruit strips, drying the rinsed jack fruit strips, sugaring the dried jack fruit strips in a vacuum manner, sugar boiling the sugared jack fruit strips, drying the sugar-boiled jack fruit strips, and packaging the dried jack fruit strips. According to the low-sugar candied jack fruit strips and the making method thereof, disclosed by the invention, by-products, namely the jack fruit strips obtained by processing the jack fruits are firstly used for making low-sugar candied fruits, the processing method is novel in conception, unique in technology, simple to operate, and easy to implement. The purposes of reducing the consumption of cane sugar and improving the flavor of the candied fruits are realized, and the problems that high-sugar candied fruits are easy to generate the situation that sugars flow off and granulated sugar is easy to form are solved. The sugar-soaking time is greatly shortened, the low-sugar candied jack fruit strips are uniform in sugar soaking, the plumpness of finished products is good, the production efficiency is high, and the low-sugar candied jack fruit strips and the making method thereof open up a new way for the reprocessing and the utilization of edible jack fruit strips in the by-products obtained by processing the jack fruits, and develop a novel leisure candied fruit, so that the added value of the jack fruits is greatly increased.
