the improvement of the exercise endurance is the most powerful macroscopic expression of the anti-fatigue capability, and the swimming time can reflect the degree of the animal exercise fatigue. As can be seen from the attached table 1, in the rice protein peptide, the swimming time of the mice of the medium and high dose groups and the positive control group is obviously prolonged compared with that of the solvent control group, and the difference is significant, which indicates that the rice protein peptide test sample can obviously prolong the swimming time of the mice, and the load swimming test result is positive.
Referring to the procedure of example 5, the ratio was adjusted, and glycine, L-alanine, and GABA were added to rice protein peptide in a certain ratio, and water was added to prepare a 3% concentration solution.
The artificial sensory evaluation method comprises the following steps: selecting 10 volunteers of 20-30 years of age, without smoking, alcohol addiction, allergy history, sensory deficiency, and health.
Taste testing procedure: after rinsing with plain water, the samples were tasted (10 seconds in the base of the tongue) and the tasting results were scored according to table 1. After one was tasted, the mouth was rinsed with warm water for 1 minute, and the next was tasted.
The tasting samples were scored by the panelists according to the sensory rating scale indexes given in the table, and the average of 10 panelists was taken as the bitterness rating score.
TABLE 7 sensory rating Scale
Index (I) You (5 fen) Liang (4 points) In general (3 points) Relatively poor (2 points) Very poor (0 point) 3% rice protein peptide reference solution
Flavor (I) and flavor (II) Fresh and sweet Is better In general Slightly improved Without any improvement Taste of enzymolysis
Bitter taste Without bitter taste Slightly bitter Slight bitter taste Has bitter taste Obvious bitter taste Bitter taste of peptide
Through the single-factor addition amount experiment, the fact that the taste of the rice protein peptide is improved by adding 1% -2% of glycine, the taste of the rice protein peptide is improved by adding 1% -1.5% of L-alanine, and the taste of the rice protein peptide is improved by adding not less than 0.5% of GABA is found in figure 2.
The effect of adding material I on the bitterness of rice protein peptide was investigated by adjusting the addition of material I and preparing a 3% strength solution based on example 1 by adding water. As can be seen from fig. 3, the sensory evaluation scores of nos. 5, 4, 2 and 6 were higher, and the effect of improving the bitterness of the rice protein peptide was better. Through the single-factor addition amount experiment, the taste of the rice protein peptide is improved by adding 0.5% -1.5% of citric acid and the taste of the rice protein peptide is improved by adding 0.5% -1.0% of stevioside according to the figure 4.
