aqueous soaking solution for manufacturing fresh-cut banana and method for manufacturing fresh-cut banana using it

摘要

PURPOSE: An immersion solution for producing a fresh and convenient banana product, and a producing method of the fresh and convenient banana product are provided to prevent the browning and texture softening of the processed banana product. CONSTITUTION: A producing method of a fresh and convenient banana product using an immersion solution comprises the following steps: dipping peeled and cut banana in the immersion solution for 1-3 minutes at room temperature; and dehydrating the banana before vacuum packaging. The immersion solution contains 10-20wt% of banana vinegar, 0.7-1.2wt% of salt, 2-5wt% of ascorbic acid, and 5-20wt% of onion extract. The banana vinegar is obtained by the following steps: mixing banana flesh with sugar in a weight ratio of 2:1; grinding the mixture before fermenting at 29-32 deg C for 3-5 days after adding 0.01-0.02% of yeast; filtering the fermented solution before secondly fermenting for 3-6 minutes; centrifugal separating the fermented solution to obtain supernatant; adding 20-30wt% of sugar into the supernatant, and aging the mixture for 1-2 months at 5-15 deg C; and heat-sterilizing the aged solution for 5-7 minutes at 80-85 deg C.
