Embodiment 1
[0039] The preparation method of dendrobium candidum beverage specifically comprises the following steps:
[0040] (1) Take 50 parts of fresh Dendrobium officinale stem sections, select those to remove weeds and mildew, and prepare to extract after the stem is crushed;
[0041] (2) Put the fresh Dendrobium candidum stem section that was fractured in step (1) into a multi-functional extraction tank, add 500 parts of drinking water for the first time, heat up to a slight boil, and keep warm (95-100°C) for 1.5 hours, and open the multi-function extraction tank at the same time. The volatile oil condenser in the functional extraction tank collects the condensate for later use; add 400 parts of drinking water for the second extraction, heat up to a slight boil and keep warm (95-100°C) for 1.5 hours; add 400 parts of drinking water for the third extraction, and heat up to a slight boil Keep warm (95-100°C) for 1 hour after boiling. Combine three extracts and let stand for half an h...
Embodiment 2
[0051] The preparation method of dendrobium candidum beverage specifically comprises the following steps:
[0052] (1) Take 20 parts of the stem section of Dendrobium candidum, select those who remove weeds and mildew, and prepare to extract after the stem is crushed;
[0053] (2) Put the dendrobium candidum stem segment fractured in step (1) into an ultrasonic extractor, add 200 parts of drinking water for the first time, extract 1 hour at 40 ° C, 60 kHz ultrasonic; add 120 parts of drinking water for the second extraction, Also at 40°C, 40 kHz ultrasonic extraction for half an hour; recover the condensate through the condensation system, combine the two extracts and let stand for half an hour;
[0054] (3) Take by weighing 3 parts of taurine, 10 parts of isomaltooligosaccharides, and 12 parts of xylitol, together with the dendrobium candidum condensate obtained in step (2), add in the extract obtained in step (2), stir, and drink Dilute the water to 500 parts, in which the ...
Embodiment 3
[0062] Functional ingredients, hygienic testing and stability experiments
[0063] Get the Dendrobium officinale canned beverage obtained in Example 1, and adopt the phenol-sulfuric acid method and derivatization-high performance liquid chromatography (GB / T 5009.169-2003) to measure the content of crude polysaccharide (calculated as glucose) and taurine in the beverage. The results showed that the crude polysaccharide content was 0.4 g / 100 ml, and the taurine content was 0.35 g / 100 ml, which met the requirements of enterprise standards and national food safety standards.
[0064] Soluble solids, heavy metals (arsenic, lead, copper, zinc, iron, tin), total number of colonies, coliforms, mould, saccharomycete, Salmonella, Shigella, gold in embodiment 1 gained Dendrobium officinale canned beverage Staphylococcus aureus and hemolytic streptococcus were tested, and the results showed that the soluble solids content was 5.86%, all kinds of heavy metals were not detected or met the c...
