Two major classes of bitter substances exist in citrus peel, one class is flavonoid compounds, the main bitter substances of which are naringin, neohesperidin, poncirin and the like, and the other class of compounds is limonoid. The bitter substance makes the dried orange peel bitter and astringent, and restricts the further development of the food application. At present, the bitter and astringent taste of the dried orange peel is covered by another or more food materials both in tea drinking and soup cooking, or the dried orange peel with larger service life is not preferable for preparing the dried orange peel beverage juice.
Fructus crataegi is rich in saccharides, proteins, fats, vitamin C, carotene, starch, malic acid, citric acid, calcium, iron and other substances, has the effects of reducing blood lipid, blood pressure, strengthening heart, resisting arrhythmia and the like, and is also a common material in beverages.
The hawthorn and dried orange peel beverages or teas in the prior art are more.
Chinese patent CN106306208A discloses a production method of dried orange peel and haw tea, which is simpler, and only cleaning, stirring, stewing and airing are carried out on haw and dried orange peel, obviously, the patent can be obtained that bitter taste of dried orange peel is not treated, the taste of tea is affected, and the tea is especially unacceptable for people not used to bitter taste.
Chinese patent CN103385506A discloses a malt, hawthorn and dried orange peel compound fermentation seasoning beverage, which comprises 60-90 parts by weight of malt, hawthorn, dried orange peel and water, 15-25 parts by weight of malt, hawthorn and dried orange peel, 5-15 parts by weight of water: mixing and soaking in a proportion of 1000, heating and boiling, and filtering to obtain juice; adding half of the water into the residue, boiling again, and filtering to obtain juice; mixing the two extractive solutions, and boiling again to obtain extractive solution; cooling the boiled extractive solution to 30-35deg.C, adding 0.5-1% by weight of beer active dry yeast, controlling the temperature to 30-35deg.C, and fermenting for 2-12 hr; boiling the extract for 30 minutes after fermentation, and sterilizing the extract at high temperature; obtaining malt, hawthorn and dried orange peel composite fermentation seasoning beverage raw pulp. The specific method described therein is not a simple and effective treatment for the bitter taste of dried orange peel.
The concentrated juice of haw and dried orange peel is used as the main raw material of haw and dried orange peel beverage, after the dried orange peel and haw are extracted, the method in reference industry is adopted, chitosan is adopted to clarify the extracting solution, impurities are removed, and the concentrated juice is finally prepared through centrifugation, filtration, membrane concentration, sterilization and filling. In the existing production process, the problems of difficult dissolution of chitosan, long time of filtered liquid, difficult cleaning caused by colloid adhesion and the like occur, meanwhile, after a period of time, a small part of visible sediment exists after the finished product of the haw dried orange peel concentrated juice is prepared into a beverage, the sediment can be dispersed after shaking uniformly, although the sediment is in an acceptable range, the quality risk is not negligible, and the problem that the clarity of the haw dried orange peel concentrated juice is insufficient is found after the reason is analyzed.
The plant raw material beverage is prepared into concentrated juice by adopting technologies such as raw material extraction, membrane concentration and the like, and is used for preparing finished beverage products, so that the problems of seasonality, transportation cost and the like of the raw materials are solved, and the plant raw material beverage has application in the beverage industry. However, because the plant raw material has complex components, if the extracting solution is not treated, the concentrated juice is easy to precipitate, and the reverse osmosis membrane is easy to be blocked, so that the service life of the membrane is shortened.
