Embodiment 1
[0027] A low-sugar Guiling jelly comprises the following components by mass:
[0028]
[0029] Wherein, the licorice extract is prepared by compound enzyme A treatment, and the bird's nest is obtained by compound enzyme B treatment.
[0030] The protease of the complex enzyme A is composed of neutral protease and papain (1:5), and the complex enzyme B is composed of exo-β-glucanase and pectinase (1:2).
[0031] The preparation method of the above-mentioned low-sugar tortoise jelly comprises the following steps:
[0032] (1) Soak the bird’s nest of the above-mentioned parts by mass in 20 times of water for 1 hour, then adjust the pH to 7.5, add compound enzyme A with an enzyme activity of 500,000 U / g licorice to enzymolyze it, and enzymolyze it The temperature is 50° C., and the enzymatic hydrolysis time is 2 hours. After the enzymatic hydrolysis, compound enzyme A is inactivated at 100° C., and the bird’s nest extract is obtained by filtration.
