(4) Determination of Total anthocyanin content
And (3) adding 1mL of sample extract into each of the two test tubes, and measuring the anthocyanin content of the Aronia melanocarpa oral liquid by adopting a pH differential method.
4. Analysis of results
1. Sensory evaluation analysis
The results are shown in fig. 1 to 5:
from fig. 1, the influence of the addition amount of Aronia melanocarpa on the sensory evaluation of the oral liquid prepared from Aronia melanocarpa can be seen. It can be found that the sensory score increases and decreases with increasing addition of Aronia melanocarpa, and the optimum addition is achieved at 55 parts. The main reason is that the Aronia melanocarpa fruit with too small addition amount lacks the fruit flavor and has poor taste; when the addition amount is too high, the sour and astringent taste of the black fruits is amplified, and the flavor of the product is affected.
Fig. 2 shows the effect of the added amount of haw extract on the sensory evaluation of the oral liquid of Aronia melanocarpa. It can be found that the sensory score increases and decreases with increasing amount of fructus crataegi extract, and the optimum is achieved at 20 parts. The hawthorn mainly has heavier taste, and can mask the fruit taste of the Aronia melanocarpa after being added in excessive amount.
Fig. 3 shows the effect of the addition amount of the jujube extract on the sensory evaluation of the oral liquid of Aronia melanocarpa. It was found that the sensory score increased and decreased with increasing addition of the jujube extract, and was optimal at 15 parts. The Chinese date is dark in color and heavy in sweetness, the taste of the oral liquid can be influenced by too little adding amount, and the color of the oral liquid can be influenced by too much adding amount.
Fig. 4 shows the effect of the added amount of rhizoma Polygonati extract on sensory evaluation of the oral liquid of Aronia melanocarpa. It can be found that the sensory score increases and decreases with increasing addition of rhizoma Polygonati extract, and the optimum is achieved at 10 parts. The rhizoma polygonati extract has a certain bitter taste, and the taste of the oral liquid can be influenced by excessive addition.
The influence of the xylitol addition amount on the sensory evaluation of the prepared Aronia melanocarpa oral liquid can be seen from fig. 5. From the graph, the sensory score increases and then decreases with the increase of the xylitol addition amount, mainly because too little xylitol addition amount can cause the oral liquid to have too heavy sour and astringent taste; when the addition amount of xylitol is too high, the special taste of the Aronia melanocarpa is covered, so that the product is too sweet, and the taste of the product is poor. The best sensory score was achieved at 5 parts added.
2. Analysis of results of orthogonal experiments
2.1 orthogonal test design
The experiment comprises a sensory evaluation group of 20 trained volunteers, and sensory evaluation of the Aronia melanocarpa oral liquid is carried out. When each person performs sensory evaluation, the sensory evaluation table is referred to, and 5mL of oral liquid is added into the mouth, so that the oral liquid is fully filled in the whole oral cavity, stays for at least 10 seconds, and needs to be rinsed at least 3 times before and after each sensory evaluation, and the total sensory evaluation is 100 minutes. The sensory scores of the Aronia melanocarpa oral liquid are taken as response values, the test design results are shown in table 3, and the sensory score variance analysis results are shown in table 4.

Note that: * Represents extremely significant (P < 0.01); * Representing significant (P < 0.05).
2.2 orthogonal test analysis
From visual analysis of results, the influence sequence of each factor on the sensory scores of the oral liquid is A > E > D=B > C, analysis of variance is carried out, the A, B, D, E factor difference is obtained to have statistical significance, and the optimal condition of the compound is A 2 B 2 C 2 D 2 E 1 The oral liquid has the sensory score of 93 minutes, which is superior to other experimental groups.
3. Product quality analysis
The sensory evaluation and quality analysis of the Aronia melanocarpa oral liquid (example 1), examples 2-4, and comparative examples 1-3, which were processed under the optimal process conditions obtained after the optimization of the orthogonal test:
table 5 sensory scores and antioxidant analysis of Aronia melanocarpa oral liquid
Figure BSA0000296653270000131
As is clear from Table 5, the Aronia melanocarpa oral liquid (example 1) prepared according to the optimal conditions obtained by the orthogonal test had a procyanidin content of 1650. Mu.g/mL, a total anthocyanin content of 1960. Mu.g/mL, a total flavone content of 4880. Mu.g/mL and a total phenol content of 4910. Mu.g/mL. IC for eliminating DPPH free radical 50 IC for scavenging hydroxyl radical at 2.76mg/mL 50 2.09mg/mL. Compared with examples 2-4, the preparation method of the oral liquid has stronger antioxidant capacity, higher active ingredient content, more uniform color and softer taste, and has the unique smell of the Aronia melanocarpa. The formula of the oral liquid has feasibility, has a certain antioxidant capacity, can improve the afterbitter taste and sour taste of the oral liquid to a certain extent, is suitable for consumers to eat, and has good product quality. Example 1 compared with comparative example 1, the casein treated Aronia melanocarpa fruit juice has lower astringency, better taste for consumer, and more active ingredient retention. Compared with comparative examples 2-3, the richer the proportion of the oral liquid, the higher the sensory score of the oral liquid, the more easily the oral liquid is liked by consumers, and the antioxidation component is improved.
