The NaHCO that concentration is 1%, 2%, 3%, 4%, 5% is added into potato slag by 6ml/g solid-liquid ratio3Solution, gap
Stirring hydrolysis 1h, filtered through gauze, centrifugation determines polysaccharide, protein, fat content in filtrate.Experimental result is shown in Fig. 1~3.
As shown in Figure 1, NaHCO is worked as3When solution concentration is 2%, protein removal rate is close to maximum (90% or so)；
Fig. 2 shows that fat content is relatively low in potato slag, is determined to 0.85%, selects NaHCO3When solution concentration is 2%, 58% is removed
Fat is remaining lower afterwards；From the figure 3, it may be seen that working as NaHCO3When solution concentration is 2%, the solubility of polysaccharide is minimum in filtrate.Knot
Close experimental result, NaHCO3Concentration be defined as 2%.In addition, the environment of a- amylase optimal pH 6,2% NaHCO3PH value is 8.5
Left and right, so NaHCO3The enzyme that goes out can also be played a part of.
