Double-component yacon fruit juice and preparation method thereof

Abstract

The invention provides yacon fruit juice and a preparation method thereof. The yacon fruit juice contains fructooligosaccharide and chlorogenic acid, wherein the content of the fructooligosaccharide is not less than 11,000mg / 100g, and the content of the chlorogenic acid is not less than 19mg / 100g. The preparation method for producing the yacon fruit juice comprises that yacon tubers are prepared into a yacon fruit juice product by cleaning, peeling, crushing, color protection, juicing, enzyme treatment, adsorption, filtration, centrifugation, blending, high-temperature sterilization and filling. The yacon fruit juice keeps the nutrient components of the fructooligosaccharide and the chlorogenic acid, ensures that the contents of the fructooligosaccharide and the chlorogenic acid do not decline along with prolonging of storage time, and also keeps the unique flavor of yacon fruits. The guarantee period of the product is 1 year, and the yacon fruit juice has no sediment or suspension and does not change color in the guarantee period.

Description

technical field [0001] The invention relates to a snow lotus juice and a preparation method thereof, in particular to a snow lotus juice containing two components of fructooligosaccharide and chlorogenic acid and a preparation method thereof. Background technique [0002] Yacon, also known as yacon, is rich in fructooligosaccharides and chlorogenic acid, and also contains essential amino acids and extremely high calcium, magnesium, iron, potassium, zinc, selenium and other elements. Regular consumption can effectively Reduce hyperlipidemia, control cholesterol and diabetes, promote human metabolism, regulate gastrointestinal tract, clear fire and detoxify, prevent acne, improve human immunity, but the water content of yacon is too large to be processed, stored and transported. The content of oligosaccharides and chlorogenic acid will decrease with the prolongation of storage time. Therefore, researches on processing yacon fruit have been carried out at home and abroad to fac...

Problems solved by technology

[0002] Yacon, also known as yacon, is rich in fructooligosaccharides and chlorogenic acid, and also contains essential amino acids and extremely high calcium, magnesium, iron, potassium, zinc, selenium and other elements. Regular consumption can effectively Reduce hyperlipidemia, control cholesterol and diabetes, promote human metabolism, regulate gastrointestinal tract, clear fire and detoxify, prevent acne, improve human immunity, but the water content of yacon is too large to be processed, stored and transported. The content of oligosaccharides and chlorogenic acid will decrease with the prolongation of storage time. Therefore, researches on processing yacon fruit have been carried out at home and abroad to facilitate transportation and storage. Chinese patent 200610010869. A snow lotus juice, which is characterized in that it is prepared by using snow lotus juice with a sugar content of 5-10%, adding metatartaric acid, tannin, gelatin and other ingredients; and another Chinese patent 200910039447.9 "Snow lotus juice and its preparation method ", the main ingredient is fresh snow lotus fruit, with fresh coriander root and fresh orange peel as auxiliary materials, added with distiller's yeast for fermentation, and squeezed to make snow lotus juice

The above two kinds of yacon fruit juices and their preparation methods do not solve the technical problem of how to keep the functional components of fructooligosaccharides and chlorogenic acid and their content decreases with the prolongation of storage time. , or chemical stabilizers, or chemical substances that produce other effects, especially the fruit juice prepared in Chinese patent 200910039447.9 is a compound fruit juice beverage of yacon, not pure fruit juice processed from yacon tubers , the juice made after adding other auxiliary materials no longer has the unique flavor of pure yacon, but is mixed with the taste of other additives, and yacon juice is no longer a green health care product after adding chemicals such as preservatives or stabilizers
