This study has shown that high-altitude boiling of reversible hydrocolloid in water alone is inadequate. It must be liquefied at a temperature of at least 100 degrees C. (212 degrees F). The use of propylene glycol alone in the liquefying bath or as an additive to water is effective in attaining this temperature. A microwave oven did not liquefy the reversible hydrocolloid adequately.
本研究表明，仅在水中对可逆水胶体进行高温煮沸是不够的。它必须在至少100摄氏度（212华氏度）的温度下液化。在液化浴中单独使用丙二醇或作为水的添加剂可有效达到该温度。微波炉不能充分液化可逆水胶体。
