Preparation method of nidus collocaliae thermal irreversible gel protective membrane and application of nidus collocaliae thermal irreversible gel protective membrane in fruity nidus collocaliae beverage process

The invention discloses a preparation method of a nidus collocaliae thermal irreversible gel protective membrane and application of the nidus collocaliae thermal irreversible gel protective membrane in fruity nidus collocaliae beverage process. The preparation method of the nidus collocaliae thermal irreversible gel protective membrane comprises the following steps: after mixing a 0.5 percent gellan gum hot solution and a 0.05 percent calcium chloride hot solution with an equal proportion (or by taking curdlan gum, sodium alginate or other thermal irreversible gel as a raw material), throwing nidus collocaliae subjected to stewing and draining off into a mixture, soaking for 15-30min, and fishing out the nidus collocaliae for cooling (normal-temperature cooling, blowing dry with cold wind, ice-water bathing and the like) to form the thermal irreversible gel protective membrane. A fruity nidus collocaliae beverage is prepared from the following components in percentage by weight: 0.3-1.5 percent of the nidus c
