1g of the liquid of the gramineae insects prepared in examples 1 to 12 of the present invention and comparative examples 1 to 11 was mixed in 2ml of 95% ethanol, and then centrifuged at 10000r/min for 10min, the supernatant was collected, 0.1ml of the collected supernatant was added to 3.9ml of a DPPH ethanol solution having a concentration of 0.063mmol/L, and the mixture was mixed uniformly, placed in dark for 10min in the dark, and the absorbance values were measured at 517nm with 95% ethanol as a blank and a reagent blank as a control, and each concentration was repeated 3 times to obtain the average value of DPPH clearance. The DPPH clearance was calculated using the following formula and the sample loading was as shown in table 1 below.
TABLE 1 sample addition meter
1. Influence of different addition amounts of enzyme
FIG. 1 is a graph showing DPPH.clearance of the solutions of the gramineous insects prepared in examples 1 and 5 of the present invention and comparative examples 2 to 4, and it can be seen from FIG. 1 that the DPPH.clearance curves show a tendency of rising first and falling second with the increase of the amount of neutral protease, and the DPPH.radical clearance reaches 28.69% when the amount of enzyme is selected to be 3000U/g as the optimum amount.
2. Influence of hydrolysis over different periods of time
Fig. 2 is a graph showing dpph. clearance of the solutions of the gramineae prepared in examples 1 and 6 of the present invention and comparative examples 5 to 7, and it can be seen from fig. 2 that the dpph. clearance tends to increase and decrease with the time of hydrolysis, and when the time of enzymatic hydrolysis reaches 2 hours (example 1), the dpph. clearance reaches the maximum, and thus it is seen that the time 2 hours is the best.
3. Influence of different hydrolysis temperatures
Fig. 3 is a dpph removal rate graph of the solutions of the graminids prepared in examples 1, 7 and 8 and comparative examples 8 and 9 of the present invention, and it can be seen from fig. 3 that the influence of the enzymolysis temperature on the dpph removal rate is large, the dpph removal rate tends to be unstable with the increase of the enzymolysis temperature, the dpph removal rate tends to increase and decrease at 40 ℃ to 60 ℃ at the enzymolysis temperature, a small and high peak value appears at 50 ℃, the dpph removal rate also tends to increase and decrease at 60 ℃ to 80 ℃, a peak appears at 70 ℃, but the dpph removal rate tends to decrease at 70 ℃, because the enzyme activity decreases until the ability to eliminate free radicals is lost at higher temperature, thereby it can be seen that the temperature of 70 ℃ is optimal.
4. Influence of different pH
Fig. 4 is a graph showing DPPH removal rates of the gramineous insects liquids prepared in examples 1, 9 to 11 and comparative examples 10 and 11 of the present invention, and it can be seen from fig. 4 that the influence of pH on DPPH removal rates is not large, the DPPH removal rates show a tendency of increasing and then decreasing as the pH increases, the pH ranges from 5 to 7, the DPPH removal rates show a tendency of gradually increasing, but the DPPH removal rates show a tendency of decreasing after 7, and thus it is seen that the pH is selected to be 7 as the optimum pH.
5. Influence of different feed-to-liquid ratios
Fig. 5 is a graph showing dpph removal rates of the solutions of the plant worms prepared in examples 1 to 4 of the present invention and comparative example 1, and it can be seen from fig. 5 that the dpph removal rates tend to increase and decrease with increasing solution-to-feed ratio, and the dpph removal rates are highest at a solution-to-feed ratio of 1:2, and thus it can be seen that the solution-to-feed ratio of 1:2 is optimal.
According to the result of the single factor, the DPPH clearance rate is taken as a target parameter, 3 factors (hydrolysis temperature, enzyme adding amount and feed-liquid ratio) are preferably selected to carry out a response surface optimization test of 3 factor 3 levels, the response surface optimization test is shown in the following table 2, and the optimal conditions of the factors are shown in the following table 3.

Note: p <0.001 is very significant star of difference; p <0.01 is the difference height significance; p <0.05 difference is significant
As can be seen from the results of table 5, P <0.01, the regression model is highly significant, with the first order terms A, B, C, B2, C2 appearing insignificant, a2 appearing significant, the interactive terms AB, AC, BC appearing insignificant, and the mismatching term P0.0544 appearing insignificant, indicating that mismatching errors are insignificant relative to pure errors.
Fig. 6-8 show that the DPPH clearance increases to a certain extent with the increase of temperature and enzyme dosage, but the clearance appears to be smaller when the temperature is higher than the upper limit of the temperature, which indicates that the enzyme activity is not favorable for survival, and the capability of DPPH for scavenging free radicals is reduced when the temperature reaches 80 ℃ or higher. It can be seen from fig. 7 that the lower the proportional water and the enzymolysis temperature, the lower the dpph clearance, which indicates that the higher the temperature, the more difficult the enzyme activity to survive, and the smaller the proportional water, the better, indicating that the proportional water is not suitable as a factor for research, because the gramineae itself contains more water. As can be seen from FIG. 8, the enzyme dosage is preferably in the range of 2000u/g to 3000u/g, and when the enzyme dosage exceeds 3000u/g, the DPPH removal rate becomes smaller and smaller, and similarly, the smaller the proportion of water is, the larger the DPPH removal rate becomes.
The optimal conditions for determining dpph. clearance obtained from the response surface were: the enzymolysis temperature is 60 ℃, the ratio of materials to liquid is 1:1, the dosage of enzyme is 3000U/g, and the DPPH under the condition has a clearance rate of 43.6888%. And (3) carrying out three parallel experiments according to the theoretical optimal conditions to obtain a measured value of 44.58%, wherein the measured value is larger than a theoretical value but is slightly different from the theoretical value, so that the equation is well fitted with the actual condition, the correctness of the established model is verified, and the process conditions are accurate, reliable and scientific.
