Embodiment 1
[0076] Prepare Polygonatum, Mulberry Leaf and Polygonatum Polygonatum Extract
[0077] Polygonatum, mulberry leaves, and Polygonatum odoratum were respectively inspected according to the Pharmacopoeia specifications, and qualified medicinal raw materials were selected. Steam Polygonatum, then weigh it with mulberry leaves and Polygonatum Polygonatum according to the ratio of Polygonatum:Mulberry Leaves:Polygonatum Polygonatum=2:1:1, put it into a flour mill, and pass through a 40-mesh sieve to obtain a mixed powder. Add 70 times of distilled water to the mixed powder, reflux in a water bath at 99°C for 3 times, each time for 1 hour, and combine the extracts of each time to obtain the extracts of Polygonatum, Mulberry and Polygonatum Polygonatum. Each 100 mL of extract corresponds to 0.5 g of raw medicinal materials.
[0078] Determination of protein sugar addition
[0079] Use 100ml of extract as a standard to prepare. Adding 0.01%, 0.03%, 0.05% and 0.08% proteoglycans w...
Embodiment 2
[0083] Determination of Added Amount of Vanillin
[0084] After determining the optimal amount of protein sugar, add 0.03%, 0.06%, 0.09%, 0.12% and 0.2% vanillin to test respectively to investigate the influence of vanillin on the flavor of the beverage, and the score obtained by sensory evaluation is The standard determines the optimal dosage. The extract is the same extract prepared in Example 1.
[0085] The result is as figure 2 It can be seen that the added amount of vanillin and the sensory score showed a trend of rising first and then falling. When the added amount was 0.09%, the score was the highest. Continue to increase the amount of vanillin, and the sensory score decreased. When the vanillin sugar content is lower than 0.03%, the beverage fragrance is relatively weak, and when the vanillin content is higher than 0.09%, the fragrance is too strong, affecting the overall taste.
[0086] Preferably, the added amount of vanillin is 0.03-0.09wt.%.
Embodiment 3
[0088] Determination of the amount of malic acid added
[0089] After determining the optimal amount of protein sugar and vanillin, 0.001%, 0.005%, 0.01%, 0.015% and 0.02% of malic acid were added respectively to investigate the effect of malic acid on the sour taste of beverages, and the score obtained by sensory evaluation was The standard determines the optimal dosage. The extract is the same extract prepared in Example 1.
[0090] The result is as image 3 As shown, the amount of malic acid added and the sensory score showed a trend of rising first and then falling. When the added amount was 0.01%, the score was the highest. Continue to increase the amount of malic acid, and the sensory score decreased. When the content of malic acid sugar is less than 0.001%, the sour taste of the beverage is relatively light, and when the content of malic acid is higher than 0.01%, the sour taste is too heavy, which affects the overall taste.
[0091] Preferably, the added amount of...
