Abstract

The invention relates to a protein-free momordica grosvenori pure-flavor concentrated juice and a production method thereof. The production method comprises the following steps: (1) after washing thefresh momordica grosvenori, squeezing the momordica grosvenori, extracting the pomace with ice water, and merging the juice and an ice water extract; (2) adjusting the pH value to alkaline, adding a protease preparation, performing enzymatic hydrolysis, heating and boiling the material, cooling the material, and performing centrifugation; (3) passing the material through a cation exchange resin column, and collecting an effluent; (4) passing the material through an anion exchange resin column, collecting the effluent, and concentrating the product. The concentrated juice obtained by the methodhas a protein content of less than 0.1%, a mass content of mogroside V as high as 4.53%, and a yield of up to 98%; The obtained concentrated juice is light yellow transparent and thick liquid, the smell is fragrant, the taste is sweet and saturated, no odor is generated, the sugar content is as high as 68 brix, and the sweetness is close to that of sucrose; The production method has the advantages of strong operability, safety, environmental protection and no pollution, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a Luo Han Guo concentrated juice and a production method thereof, in particular to a protein-free Luo Han Guo pure flavor concentrated juice and a production method thereof. Background technique [0002] Mangosteen is known as the "fairy fruit". It is mainly produced in the mountainous areas of Lingui County and Yongfu County in Guilin City. It is a rare local product in Guilin. The fruit has high nutritional value and is rich in vitamin C, mogroside V, fructose, glucose, protein, lipids, etc. Luo Han Guo is sweet in taste and cool in nature, and it belongs to the lung and large intestine meridian. Modern medical research has confirmed that the mogroside contained in Luo Han Guo is a natural sweetener 400 times sweeter than sucrose, but it does not produce calories, so it is an ideal alternative drink for people who are not suitable for sugar, such as diabetes and obesity. [0003] The protein content in Luo Han Guo is rich, ...
