Description

Technical Field

[0001] The present invention relates to the technical field of health tea, and specifically relates to a fermented tea for intestinal regulation and a production method thereof. Background Art

[0002] Cool herb fermented tea is made by decocting and brewing Chinese herbal medicines with the functions of dispelling dampness, clearing heat and detoxifying, and is a kind of drink with certain functional effects. Modern cool herb fermented tea is classified as a herbal plant beverage, mainly referring to one or several of the plants or their extracts that are both edible and medicinal or permitted to be used by the state as the main raw materials, with or without adding other food raw materials and food additives and processed. With the continuous development of China's economy and the improvement of people's health awareness, the consumption of herbal tea beverages in the domestic market is constantly expanding, and the products of herbal tea beverages are becoming increasingly diversified. However, the current cool herb fermented tea products have a single flavor, and the functions are mainly only in the aspect of "reducing internal heat", and the sweetness mainly comes from sucrose, which is difficult to meet the diverse flavor needs of consumers.

[0003] The fruits of Lonicera caerulea are juicy and rich in various amino acids and vitamins. In addition to having extremely high nutritional value, there are also rich bioactive substances in the fruits, and the medicinal value is also extremely high. Lonicera caerulea is cold in nature, can clear heat and purge fire, detoxify and reduce swelling, and can effectively improve the liver's detoxification function and clear the liver and improve eyesight. However, Lonicera caerulea tastes sour and has a rather bitter taste, and is not suitable for long-term consumption. Therefore, the present invention provides a fermented tea for intestinal regulation and a production method thereof. Summary of the Invention

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a fermented tea for intestinal regulation and its preparation method, having the following beneficial effects:

[0021] For the fermented tea for intestinal regulation and its preparation method, by combining the characteristics of different sweeteners, the efficacy of the herbal tea and the sensory characteristics, instead of using artificial synthetic sweeteners, natural sweeteners with good efficacy are selected. Stevia rebaudiana, a natural plant, is specially selected. The main component of it is stevioside, which has high sweetness, low calories, and has multiple effects such as promoting metabolism, lowering blood sugar, lowering blood pressure, anti-tumor, improving immunity, and regulating gastric acid. At the same time, maltose with the effects of strengthening the spleen and stomach, moistening the lungs and relieving cough, and rock sugar with the effects of tonifying the middle qi, soothing the stomach and moistening the lungs, nourishing yin and promoting fluid production, and moistening the lungs and relieving cough are selected. Fresh reed rhizome with the effects of clearing away heat and promoting fluid production, moistening the lungs and soothing the stomach, removing vexation and stopping vomiting, and Lonicera caerulea L. with the effects of clearing heat and detoxifying, anti-inflammatory, anti-viral, and anti-tumor are used, and the two are fermented by using the method of microbial fermentation to prepare reed rhizome and Lonicera caerulea L. vinegar, which contains more than ten organic acids and various amino acids required by the human body, has a sweet and fresh taste, a suitable sour taste, and a special fruit aroma, can promote metabolism, effectively regulate the gastrointestinal tract, regulate the acid-base balance, and eliminate fatigue. The citron used has an aroma, is pungent, slightly bitter and sour, and is warm in nature, with the effects of soothing the liver and regulating qi, widening the chest and resolving phlegm, removing dampness and regulating the middle. However, as the boiling time of the citron prolongs, its sour and bitter taste becomes stronger and stronger, irritating the throat, and it is difficult for the prepared herbal tea to be accepted by the public. Therefore, in this application, maltose with the effects of strengthening the spleen and stomach, moistening the lungs and relieving cough, and rock sugar with the effects of tonifying the middle qi, soothing the stomach and moistening the lungs, nourishing yin and promoting fluid production, and moistening the lungs and relieving cough are used. The citron sugar paste prepared by the three has a golden color, is sweet, sour, soft, glutinous and smooth, has a special fruit aroma, effectively neutralizes the bitterness and sourness of the citron, that is, enhances the special fruit aroma of the citron and improves its effects of resolving phlegm, promoting qi movement, relieving cough and asthma. At the same time, in this application, the citron is pickled with salt, which largely removes the bitter and astringent taste of the citron, neutralizes the strong sour taste, makes the citron fresh, sour and crispy, and can enhance its effects of promoting qi movement to relieve pain and strengthening the stomach and promoting digestion.

[0078] In summary, for the fermented tea used for intestinal regulation and its production method, by considering the characteristics of different sweeteners, combining the efficacy and sensory characteristics of Liangcha, without using artificial synthetic sweeteners, natural sweeteners with good efficacy are selected. Stevia rebaudiana, a natural plant, is specifically selected. The main component of it is stevioside, which has a high sweetness, low calories, and has various effects such as promoting metabolism, lowering blood sugar, lowering blood pressure, anti-tumor, enhancing immunity, and regulating gastric acid. At the same time, maltose with the effects of strengthening the spleen and stomach, moistening the lungs and relieving cough, and rock sugar with the effects of tonifying the middle qi, regulating the stomach and moistening the lungs, nourishing yin and promoting fluid production, and moistening the lungs and relieving cough are selected. By using fresh reed rhizome with the effects of clearing heat and promoting fluid production, moistening the lungs and regulating the stomach, removing vexation and stopping vomiting, and blue honeysuckle with the effects of clearing heat and detoxifying, anti-inflammatory, anti-viral, and anti-tumor, and through the method of microbial fermentation, the two are fermented to prepare reed rhizome and blue honeysuckle vinegar, which contains more than ten organic acids and various amino acids required by the human body, has a sweet and fresh taste, a suitable sour taste, and a special fruity aroma, can promote metabolism, effectively regulate the gastrointestinal tract, regulate the acid-base balance, and relieve fatigue. The citron used has an aroma, tastes pungent, slightly bitter, sour, and is warm in nature, with the effects of soothing the liver and regulating qi, widening the chest and resolving phlegm, removing dampness and regulating the middle. However, as the boiling time of the citron prolongs, its bitter and sour taste becomes stronger and stimulates the throat, and it is difficult for the prepared Liangcha to be accepted by the public. Therefore, in this application, maltose with the effects of strengthening the spleen and stomach, moistening the lungs and relieving cough, and rock sugar with the effects of tonifying the middle qi, regulating the stomach and moistening the lungs, nourishing yin and promoting fluid production, and moistening the lungs and relieving cough are used to prepare the citron sugar paste, which has a golden color, is sweet, sour, soft, glutinous and smooth, has a special fruity aroma, effectively neutralizes the bitter and sour taste of the citron, that is, enhances the special fruity aroma of the citron and improves its effects of resolving phlegm, promoting qi, relieving cough, and calming asthma. At the same time, in this application, the citron is pickled with salt, which largely removes the bitter and astringent taste of the citron, neutralizes the strong sour taste, makes the citron fresh, sour and crispy, and can enhance its effects of promoting qi and relieving pain, strengthening the stomach and promoting digestion.
