Embodiment 1

[0026] Take 3150g of fresh and ripe papaya, peel and remove seeds, weigh 2450g, add 7.4L of water at a ratio of 1:3, mash with a mixer, heat to 42-45°C, and adjust the pH to 3.8 with 0.1mol / L HCl or sulfuric acid According to the dosage ratio of pectinase 750u / g papaya, add 1.84 million units of pectinase, stir well, and maintain pH3.5~4.0, 42℃~45℃ for 3 hours for hydrolysis. After enzymatic hydrolysis, heat up to 100°C, keep it warm for 10 minutes to inactivate the enzyme, and lower the temperature to below 30°C. Suction filter to obtain 6.5L of supernatant, centrifuge the residue with a centrifuge, collect the supernatant to obtain 0.5L, combine the supernatant, a total of 7.0L, adjust the pH to 6.8-7.0 with 1mol / L NaOH, and set the molecular cutoff to 100K Ultrafiltration was carried out with a filter membrane, and the filtrate was collected to obtain 6.5 L, which was the refined solution of papaya extract. Sampling for detection of polysaccharides, peptides, content, acid...

Embodiment 2

[0028] Take 2150g fresh and ripe papaya, weigh 1677g after peeling and removing seeds, add 5.0L of water at a ratio of 1:3, mash with a mixer, heat to 42-45°C, and adjust the pH to 8.0-9.0, according to the dosage ratio of glucoamylase 150u / g papaya, add 250,000 units of glucoamylase, stir well, maintain pH 8.0, and hydrolyze at 42°C-45°C for 3 hours. After enzymatic hydrolysis, heat up to 100°C, keep it warm for 10 minutes to inactivate the enzyme, and lower the temperature to below 30°C. Suction filter to obtain 4.4L supernatant, centrifuge the residue with a centrifuge, collect the supernatant to obtain 0.3L, combine the supernatant, a total of 4.7L, adjust the pH to 6.8-7.0 with 0.1mol / L HCl, and reserve the molecular cut-off of 100K Ultrafiltration was carried out with a filter membrane, and the filtrate was collected to obtain 4.4 L, which was the refined solution of papaya extract. Sampling for detection of polysaccharides, peptides, content, acidity, etc., for later u...

Abstract

The invention discloses a method for preparing papaya extract by the technology of biological enzyme and the application. The method comprises the following steps sequentially: peel and seeds of a fresh and mature papaya are removed, water is added, then the papaya is smashed for enzymatic hydrolysis and then enzymatic inactivation; clear solution is separated by centrifugalization; the clear solution is hyperfiltrated by a filterable membrane; filtrate is collected, thereby obtaining the concentrated solution of the papaya extract. The extracting method is simple, safe, pollution-free, high in yield and low in cost; and the obtained concentrated solution is rich in active material, such as micromolecule polypeptide, amino acid, cellulose, amylose, trace element and the like, and is applicable to being prepared into high-end beverage.

Description

technical field [0001] The invention relates to a preparation method of papaya extract. Background technique [0002] Papaya is a fruit with extremely nutritious value and good for health. In the list of healthy foods launched by the World Health Organization (WHO) in 2007, papaya has become the "top list" of fruit series due to its rich nutrients and good health care functions. The new champion". [0003] Papaya fruit is rich in nutrition and sweet in flesh, known as "the best fruit in Lingnan". It is rich in many vitamins, especially vitamin A and vitamin C. The vitamin A content is 20 times higher than that of pineapple; every 100g of fruit juice contains 50mg of vitamin, which is 48 times that of apple. Papaya is rich in more than 17 kinds of amino acids, sugar, protein, crude fiber and other nutrients, as well as elements such as calcium, iron, phosphorus, sodium, potassium, magnesium, and β-carotene. Every 100g of fresh papaya fruit contains lysine 34mg, valine 28m...
