Example 17
A method for preparing a fermented moringa leaf tea, which comprises the steps of fermenting and drying the moringa leaves subjected to wall breaking prepared in the previous examples 1 to 16.
In this embodiment, the moringa leaves after the low-temperature freezing treatment are placed in a fermentation box and fermented for 15 days at the temperature of 80 ℃, so that flavonoids released from the moringa leaves after the wall breaking can be sufficiently fermented and converted, and after the fermented moringa leaf tea is soaked, the nutrients and flavonoids in the tea soup are higher.
After the fermentation is completed, the moringa leaves are dried, in the embodiment, the leaves are dried at 80 ℃ for 24 hours, so that the moisture content of the dried moringa leaves is not more than 10%, and the prepared moringa leaves are prevented from being mildewed quickly in the later storage process.
Example 18
A method for preparing fermented moringa leaf tea comprises the steps of sequentially fermenting and drying the moringa leaves subjected to wall breaking prepared in the previous examples 1 to 16, wherein in the present example, two-stage fermentation is adopted for fermentation.
In this embodiment, firstly, the moringa leaves subjected to low-temperature freezing treatment are placed in a fermentation box, and are fermented for 5 days at 80-85 ℃ to allow flavonoid compounds released from the moringa leaves to be fermented and converted at a high temperature for a short time, so that the flavonoid compounds are prevented from being inactivated at a high temperature for a long time, the fermentation box is cooled to 70-75 ℃ to be fermented for 10 days, the flavonoid compounds subjected to the first fermentation and conversion are kept at a cross-bottom temperature for a long time, the fermentation and conversion are more thorough, the flavonoid compounds released from the moringa leaves subjected to the first fermentation and conversion can be sufficiently fermented and converted, and the nutrient substances and the flavonoid compounds in the tea soup are higher after the moringa leaves are soaked.
After the fermentation is completed, the moringa leaves are dried, in the embodiment, the leaves are dried at 80 ℃ for 24 hours, so that the moisture content of the dried moringa leaves is not more than 10%, and the prepared moringa leaves are prevented from being mildewed quickly in the later storage process.
The following table lists the content of flavonoids in the tea soup after the final product prepared in the above example was used for tea infusion:
in summary of the above data, according to the moringa oleifera leaf wall breaking method disclosed by the invention, after wall breaking and fermentation are carried out, and a finished product of moringa oleifera leaf tea is prepared, the content of flavonoid compounds in the tea soup after soaking is increased in comparison with the content of flavonoid compounds in the tea soup after soaking of ordinary moringa oleifera leaf tea.
Comparing the above data, the wall breaking effect of the dry moringa leaf tea is inferior to that of the fresh moringa leaf tea, because ice crystals are generated in cells after the cell walls are in a low-temperature environment, the generated ice crystals can puncture the cell walls, and the water and the cell sap in the cells of the dry moringa leaves are less than those of the fresh moringa leaves, so that the ice crystals formed in the dry moringa leaves are less than those in the previous moringa leaves, and therefore, the effect of the dry moringa leaves on puncturing the cell walls by the ice crystals is poorer than that of the fresh moringa leaves.
In addition, the freezing temperature has a great influence on the wall breaking effect, if the wall breaking temperature is too low, active substances in moringa leaves can be invalid, so that the total flavonoids capable of being converted can be removed after reduction, meanwhile, from the perspective of industrial application, when the freezing temperature is too low, liquid nitrogen needs to be used for freezing, so that the preparation cost can be greatly increased, from the aspects of effect and energy efficiency, the freezing temperature cannot be too low, and the optimal temperature has the best effect at-20 ℃.
Meanwhile, the freezing time cannot be too long, the reason is similar to the freezing temperature, the moringa leaves cannot be in a too long freezing environment, and the freezing has small influence on cells but has large influence on active substances in the moringa leaves.
The freezing times have positive help for wall breaking, and multiple freezing can lead the cell wall to form multiple wall breaking at a proper temperature, such as-20 ℃, and simultaneously, the moringa leaves are not in a long-time freezing environment, so that the active substances in the moringa leaves can be continuously and effectively ensured, the wall breaking degree is also improved, and more flavones can be released.
Furthermore, in the preparation method of the fermented moringa leaf tea disclosed by the invention, after the wall breaking method disclosed by the invention is adopted for pretreatment, different fermentation modes are adopted, so that the flavonoid compounds which can be finally soaked in the tea soup are greatly influenced, compared with two-stage fermentation, when one-stage high-temperature fermentation is adopted, the content of the flavonoid compounds in the tea soup soaked in the finished product is reduced in a fault manner, and a large amount of flavonoid compounds are decomposed and inactivated in a high-temperature environment due to overlong high-temperature fermentation time, so that the content of the flavonoid compounds is reduced in response after the final product is soaked.
In the embodiment described in the present invention, the optimized wall-breaking embodiment is embodiment 2, and the optimized preparation of fermented tea leaves is to utilize the wall-broken finished product prepared in embodiment 2 to ferment in the preparation method of fermented moringa leaf tea described in embodiment 18, wherein the content of flavonoids in the fermented finished product after being soaked in tea soup is 26.4mg/g, which is much higher than that of common moringa leaf tea soaked in 3.6 mg/g.
Although the invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More specifically, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure and claims of this application. In addition to variations and modifications in the component parts and/or arrangements, other uses will also be apparent to those skilled in the art.
