Problems solved by technology

[0003] At present, the production of Luo Han Guo concentrated juice adopts the method of steaming and extracting. This method has a high operating temperature and requires the consumption of pure water and steam, which has a negative impact on the taste of Luo Han Guo.
In addition, because the pectin structure contains 10% to 40% forked regions, these forked regions make it very difficult to degrade pectin, so that pectinase cannot completely degrade pectin

example 1

[0021] Clean 1 ton of Luo Han Guo fresh fruit in a fruit washing machine. The Luo Han Guo is crushed in a screw press and made into a pulp in a fruit and vegetable pulper. Add citric acid to adjust the pH to 5.5, control the temperature to 50° C., and add 4 kg of immobilized fruit pulp enzyme. After 30 minutes of enzymatic hydrolysis, filter the juice with a plate and frame filter. Add 5g ultrafiltration enzyme in fruit juice, after 60 minutes, carry out ultrafiltration. Add 1 kg of active carbon produced in Japan to the clarified fruit juice, stir for 5 minutes and then centrifuge the active carbon. The deodorized fruit juice is vacuum-concentrated to 60Brix to obtain 80kg of concentrated juice, which is packaged after ultra-high temperature instant sterilization to obtain the deodorized concentrated juice of Luo Han Guo fresh fruit.

example 2

[0023] Clean 1 ton of Luo Han Guo fresh fruit in a fruit washing machine. The Luo Han Guo is crushed in a screw press and made into a pulp in a fruit and vegetable pulper. Without acid adjustment, add 10kg of immobilized fruit pulp enzyme at room temperature of 20°C. After enzymatic hydrolysis for 60 minutes, filter the juice with a plate and frame filter. Add 2g of ultrafiltration enzyme to the fruit juice, and perform ultrafiltration after 60 minutes. Add 3kg of special gac to the juice that has been clarified, and centrifuge the gac after stirring for 10 minutes. The deodorized fruit juice is vacuum-concentrated to 60Brix to obtain a 75kg concentrated juice product, which is packaged after ultra-high temperature instant sterilization to obtain the deodorized concentrated juice of Luo Han Guo fresh fruit.

example 3

[0025] Clean 1 ton of Luo Han Guo fresh fruit in a fruit washing machine. The Luo Han Guo is crushed in a screw press and made into a pulp in a fruit and vegetable pulper. Add citric acid to adjust the pH to 3.5, control the temperature to 40° C., and add 1 kg of immobilized fruit pulp enzyme. After 40 minutes of enzymatic hydrolysis, the juice was filtered out with a plate and frame filter. Add 2g of ultrafiltration enzyme to the fruit juice, and perform ultrafiltration after 60 minutes. Add 5kg special-purpose gac in the fruit juice that obtains clarification, centrifuge gac after stirring for 10 minutes. The deodorized fruit juice is vacuum-concentrated to 60Brix to obtain 82kg of concentrated juice product, which is packaged after ultra-high temperature instant sterilization to obtain the deodorized concentrated juice of Luo Han Guo fresh fruit.

Abstract

The invention discloses a process for preparing odor-removed concentrated juice of Momordica grosvenori fresh fruits, which comprises cleaning Momordica grosvenori fresh fruits, commuting into fruit pulps, then adjust pH and temperature of the fruit pulp, chaging immobilizing pulp enzyme for decomposing main parts of the pectine, hydrolyzing the methyl galactonic acid residual in the pectine, cracking plant cell walls, releasing more fruit juice and clearing the fruit juice simultaneously, then ultrafiltrating the fruit juice and carrying out odor-removing treatment, concentration, sterilizing and packaging. The process of the invention has the advantages of simplified and effective procedures, high rate of extract yield and low cost of preparation, the obtained fresh Momordica grosvenori concentrated juice has good taste, high sugariness and transparent appearance with no precipitation after long time storage.

Description

Technical field: [0001] The invention relates to a fruit juice production method, in particular to a deodorization and concentration production method of fresh Luo Han Guo. Background technique: [0002] Luo Han Guo is a perennial climbing vine of Cucurbitaceae. It is rich in polysaccharides and vitamins, rich in unsaturated fatty acids and a variety of trace elements and amino acids beneficial to the human body. It is cool and sweet in nature, and has the effect of treating coronary heart disease and preventing vascular sclerosis. It has been a natural tonic for strengthening the body and prolonging life among the people for a long time. The glucoside V of Luo Han Guo is 300 times sweeter than sucrose, so the concentrated juice of Luo Han Guo not only has health benefits, but also is a good sweetener. [0003] At present, the production of Luo Han Guo concentrated juice all adopts the method of steaming and extracting with water. This method has a high operating temperatur...
