PREPARATION OF FREEZE-DRIED INSTANT PLAIN NOODLES HAVING BEST BEFORE DATE OF ONE OR MORE YEARS BY USING BRINE SOLUTION DURING BOILING AND SUITABLE PRELIMINARY FREEZING-DRYING METHOD

摘要

PURPOSE: A method of making freeze dried instant plain noodles(without meat) by using a brine solution during boiling and a suitable preliminary freezing-drying method is provided. It prevents reduction of starchiness and stickiness of noodles during reconstitution and enables the noodles to be reconstituted in 1 to 3min in hot water while having a best before date of 1 or more years. CONSTITUTION: Plain noodles without meat are boiled with boiling brine solution, dipped in cold water, dehydrated and formed into noodles. Then it is slowly frozen at 0 to -20deg.C for 8 to 14hr for a first preliminary freeze-drying, quickly frozen at -30deg.C or less for 2 to 4hr for a second preliminary freeze-drying and freeze-dried at -40deg.C or more for 28 to 32hr under depressurized conditions of below 0.5torr to reduce moisture content.
