Performance test
Detection method
The instant storage-resistant fern root powder of examples 1-10 and comparative examples 1-8 is tested for storage resistance according to national standards GB/T4789.1-2010, GB4789.10-2010 and GB 4789.15-2010, and the test results are shown in Table 1 after 3 d.
TABLE 1 shelf-Life Performance test data for the instant shelf-life fern root powder of examples 1-10 and comparative examples 1-8
Figure BDA0003378713650000081
Taking the instant storage-resistant fern root powder of examples 1-10 and comparative examples 1-8, arranging 20 testers to take a trial eating, and evaluating the mouthfeel, wherein the value is 1-10 points, and the mouthfeel evaluation standard is as follows: the good food is eaten at 0-3 points, generally at 4-7 points and the good food is eaten at 8-10 points, the better the evaluation is, the higher the score is, the score can be one bit after the decimal point, finally, the average value is taken, the data is rounded, and the test results are shown in table 2.

As can be seen from the analysis of examples 1 to 3 and comparative example 1 in combination with table 1, the variety and composition of the raw materials of fern root powder are optimized and adjusted, and the fern root powder of example 3 has better taste and storage stability.
According to analysis examples 4-5 and comparative examples 2-6 and table 1, the preservative has a better preservation effect when the preservative is compounded by polysaccharide, boron aspartate and hydroxytyrosol according to the mass ratio of 15:7:3, and the total bacteria number after 3 days of storage is reduced by 34% compared with that of comparative example 6. And the bacteriostatic effect of the compound of the polysaccharide and the boron aspartate is better than that of the compound of the boron aspartate, the hydroxytyrosol and the chitosan when the polysaccharide and the boron aspartate are used independently, the counting amount of the mould and the yeast is reduced from 833.2CFU/g (ml) to 33.6CFU/g (ml) at most, and the bacteriostatic effect and the storage resistance are better.
According to analysis examples 6-7, examples 8-9 and comparative example 7 and table 1, the polysaccharide in the preservative has a better bacteriostatic effect when being compounded by lactobacillus extracellular polysaccharide, soybean polysaccharide and hyaluronic acid according to the mass ratio of 5:10: 3.
It can be seen from the analysis of example 10 and comparative example 8 and the combination of table 1 that the addition of agar oligosaccharide in the raw material further improves the inhibition effect on microorganisms, the total bacteria count after 3 days of storage is reduced to 9522CFU/g (ml), and the storage resistance is better.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
