Problems solved by technology

At present, domestic pectin production is still in the initial stage of research and development, mainly because the process is not mature enough and the cost is too high. Therefore, the extraction process of okra pectin is improved to develop a low-energy, low-cost, high-yield The new process of extracting okra pectin with good efficiency and product quality has great significance

Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention is further described:

[0014] Such as figure 1 A method for extracting okra pectin includes the following steps: (1), okra is washed and dried, then chopped to obtain pieces; (2), adding distilled water to the pieces and heating to boiling; (3 ), ammonium oxalate was added to the boiling liquid and stirred until dissolved; (4), the boiling liquid was ultrasonically extracted to obtain an extract; (5), the extract was centrifuged to obtain a supernatant; (6), the After the above supernatant is concentrated, ethanol is added to settle; (7), the centrifuged solid obtained after the settled liquid is centrifuged is dried to obtain pectin; the boiling time lasts 30 minutes; the solidification of the okra and distilled water The liquid ratio is 1:10; the temperature of the ultrasonic extraction is 80°C; the concentration of the ethanol is 95%; the concentration temperature is 60°C; the concentration of th...

Abstract

The invention discloses an extraction method of abelmoschus esculentus pectin in the field of pectin preparation. The method comprises the following steps that (1) abelmoschus esculentus is washed anddried and is then cut up to obtain cut-up blocks; (2) the cut-up blocks are added into distilled water for heating to be a boiling state; (3) ammonium oxalate is added into the boiling liquid; stirring is performed until the ammonium oxalate is dissolved; (4) the boiling liquid is subjected to ultrasonic extraction to obtain extraction liquid; (5) the extraction liquid is subjected to centrifugalseparation to obtain supernate. The abelmoschus esculentus is washed and dried and is then cut up; boiling water is used for heating; after the ammonium oxalate is added, ultrasonic extraction is performed; then, centrifugal separation is performed; the obtained supernate is concentrated; then, ethanol is added for sedimentation; then, centrifugal separation is performed; drying is performed to obtain the pectin; the pectin extraction process can realize the goals of low energy consumption, low cost and high yield; the pectin quality is greatly improved. The extraction method can be used in the preparation of the abelmoschus esculentus pectin.

Description

technical field [0001] The invention relates to a method for preparing essential oil, in particular to a method for extracting okra pectin. Background technique [0002] Okra, okra, okra, etc. are annual herbaceous plants of the Malvaceae okra family, suitable for growing in tropical, subtropical and Mediterranean climate zones. At present, many provinces in southern my country have been planted on a large scale. Tender okra fruit is rich in tissue mucus composed of collagen and polysaccharides. The main components of the mucus are pectin and viscous protein. Pectin has good emulsifying, thickening and stabilizing effects, and has been widely used in the food field; pectin has antibacterial, detoxifying, lowering blood sugar and cholesterol, enhancing human endurance, etc., and is also widely used in medicine; Pectin also has a special gel effect, which can fix water, combine with fibers to form plant tissue, and have the functions of radiation protection and skin protectio...
