Problems solved by technology

CN102154400A uses bean dregs as raw material, through pretreatment of bean dregs, steam explosion, ultra-fine pulverization, enzymolysis and enzymatic slurry drying, to obtain pure natural, fully water-soluble dietary fiber products, although steam explosion and enzyme treatment are used in this method , but without the use of ultrasound-assisted lye extraction
CN103445187A combines extrusion modification with ultrasonic-assisted alkaline enzymatic extraction to shorten the time for SDF modification and improve the extraction rate of SDF. Although there is an ultrasonic-assisted enzymatic method, steam explosion is not used for pretreatment
Therefore, there are no direct reports at home and abroad on the extraction method of banana flower as raw material, using steam explosion, ultrasonic lye treatment combined with cellulose degradation

Embodiment 1

[0021] Choose freshly picked banana flowers, remove the outer flakes and flowers, then chop them to 5cm, put 100g of the sample into the steam explosion tank of the 400ml steam explosion test bench, and release it instantly after 90s under the pressure of 1.5MPa (Release speed 0.00875s), collect juice and residue. Add 2 times the volume of 1% NaOH solution to the collected materials, ultrasonic treatment for 10 minutes, power of 70W, put the extract in a centrifuge, centrifuge for 10 minutes, 5000r / min, and then filter. Add 5% cellulase to the filtered residue, react for 2h at 35°C, pH5, add an equal volume of 1% NaOH solution, sonicate for 5min, power 70W, put the extract in a centrifuge Centrifuge for 10min, 5000r / min, and then filter. The combined filtrates were added with 30ml of 30% H 2 O 2 , Placed at room temperature for 48h. The decolorized liquid was centrifuged, filtered, and adjusted to pH 9, and after standing for 3 hours, it was filtered again. The pH value of t...

[0024] Choose freshly picked banana flowers, remove the outer flakes and flowers, then chop them to 5cm, put 100g of the sample into the steam explosion tank of the 400ml steam explosion test bench, and release it instantly after 90s under the pressure of 2.0MPa (Release speed 0.00875s), collect juice and residue. Add 2 times the volume of 1% NaOH solution to the collected materials, ultrasonic treatment for 20min, power of 150W, put the extract in a centrifuge, centrifuge for 10min, 5000r / min, and then filter. Add 5% cellulase to the filtered residue, react for 2h at 35°C, pH5, add an equal volume of 1% NaOH solution, sonicate for 10min, power 150W, put the extract in a centrifuge Centrifuge for 10min, 5000r / min, and then filter.

Abstract

The invention provides a preparation method of banana flower soluble dietary fiber. The method is characterized by comprising the following steps of washing and slicing banana flowers buds, bursting the banana flowers buds through vapor, extracting the banana flowers buds through ultrasonic wave by using alkaline liquid, performing enzyme treatment on an obtained mixture, centrifuging the mixture, filtering the mixture, decoloring, precipitating, concentrating, spray drying and the like, and the soluble dietary fiber with good quality and high purity can be obtained. By adopting the vapor bursting and ultrasonic alkaline liquid treatment technology, the non-cellulosic components in the banana flower can be degraded; by adding cellulose, cellulose is degraded, so that the yield of the soluble dietary fiber can be increased. The extraction rate of the prepared banana flower soluble dietary fiber is 50 to 75 percent.

Description

Technical field [0001] The invention belongs to the field of health food raw material processing, and relates to the processing of soluble dietary fiber, in particular to a processing method of banana flower soluble dietary fiber. Background technique [0002] Dietary fiber (DF) is a type of edible plant or similar carbohydrates that cannot be digested and absorbed by the human small intestine, but can be fully or partially fermented in the large intestine. DF can be divided into soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) according to its water solubility. SDF mainly includes pectin, dextran, gum, etc., while IDF mainly includes cellulose, Part of hemicellulose, lignin, wax, etc. Most of the fiber products sold at home and abroad are insoluble and synthetically water-soluble (mainly chemical synthesis). The insoluble components in dietary fiber mainly act on the intestinal tract to produce mechanical peristalsis effects, while the water-soluble components pla...
