[0017] According to the components of turmeric, the present invention selects two sets of compound enzyme preparations, type I compound enzyme preparation, which are used to loosen and diverge the tissue structure of yam, so that th...
Embodiment 2
[0030]In the first hydrolysis step (3), adjust the solid-liquid ratio to 1:6, pH value to 6.0, add 1% of the type I compound enzyme preparation based on the dry weight of yam, and hydrolyze at 45°C for 10 hours.
[0031] In the secondary hydrolysis step (4), adjust the pH to 6.0, add 0.5% of the type II compound enzyme preparation based on the dry weight of yam, and hydrolyze at 65°C for 1.5 h.
[0032] The present invention is to recycle waste sugar liquid, which is a pollutant. In step (5), the filtered liquid is filtered and washed with water, and the filtrate is reduced in pressure and concentrated. Coarse sugar powder can be used as raw materials in fermentation industry, feed industry, and bio-organic fertilizer industry.
