Problems solved by technology

A large number of experiments have shown that the solubility of sagittarius starch is low, which is mainly because the structural characteristics of sagittarius starch granules make the extraction of sagittarius starch difficult
Therefore, the deep processing of sagittarius starch is limited, and it is difficult to produce in large quantities

Embodiment 1

[0018] Embodiment 1 (do not add ultrasonic)

[0019] First of all, put the sagittarius raw material into the water, wash it clean, and do a good job of peeling and removing impurities. Then weigh 75g of Sagittarius raw material, add water to beat according to the mass ratio of 1:1, and then perform centrifugation. After centrifugation for 20min, remove the lower layer of sediment, put it in a clean petri dish and dry it in an oven for 48h, grind, sieve, weigh Heavy; Determination of the extraction rate and purity of Sagittarius starch according to the following method.

[0020] The assay method of Sagittarius starch extraction rate among the present invention is as follows:

[0021] The starch extraction rate is the percentage of the pure starch mass in the extract to the starch mass in the raw material.

[0022]

[0023] Where: X w -the extraction rate (g / 100g) of measured sagittarius starch;

[0024] X—the content of the measured arrowroot starch (g / 100g);

Embodiment 2—7

[0037] Embodiment 2-7 (different dual-frequency ultrasonic frequencies)

[0038] Multi-mode Ultrasonic Pretreatment of Sagittarius Starch

[0039] First of all, put the sagittarius raw material into the water, wash it clean, and do a good job of peeling and removing impurities. Then weigh 75g of sagittarius raw material, add water to make a slurry according to the mass ratio of 1:1, and put the starch homogenate into different ultrasonic conditions for ultrasonic pretreatment. Then carry out centrifugation, after centrifuging for 20 minutes, remove the sediment layer, put it into a clean petri dish and place it in an oven to dry for 48 hours, grind, sieve, and weigh.

[0040] (1) Single factor experiment of ultrasonic frequency: the ultrasonic time was determined to be 20 minutes, the ultrasonic power density was 180W / 150mL, and the ultrasonic working mode was selected as synchronous multi-frequency. The frequency of dual-frequency ultrasound for the treatment of Sagittarius...

Abstract

The invention discloses a dual-frequency ultrasonic extraction method of sagittaria sagittifolia starch, belonging to the technical field of plant starch extraction. The method comprises the followingsteps: putting a sagittaria sagittifolia raw material into water to clean, and performing peel and impurity removal treatment; weighing the sagittaria sagittifolia raw material, adding water for pulping at a mass ratio of 1:1, homogenizing the starch and putting in different ultrasonic conditions to perform ultrasonic pretreatment; then, performing centrifugal operation, taking lower-layer precipitate after centrifuging for 20 min, putting in a clean culture dish and placing in an oven to dry for 48 h, grinding and sieving to obtain the sagittaria sagittifolia starch. The method can speed upthe extraction process of the sagittaria sagittifolia starch through ultrasonic-assisted extraction, when a single frequency in optimal conditions is 40 / 60 kHz, the extraction rate and purity of the sagittaria sagittifolia starch are respectively 87.45% and 75.00%, the extraction rates are 66.0% and 51.8% higher than that of the sagittaria sagittifolia starch not subjected to ultrasonic treatment.The operation process is simple and easy, the extraction rate and purity of the sagittaria sagittifolia starch can be greatly improved, and the energy consumption is relatively low.

Description

technical field [0001] The invention relates to the technical field of extracting plant starch, in particular to a method for extracting sagittarius starch with the aid of dual-frequency ultrasonic waves using sagittaria as a raw material. Background technique [0002] Sagittarius, also known as swallowtail grass, is an aquatic herb planted in low-lying paddy fields. Fresh sagittarius is long oval or oval, with a length of about 2.2-4.5cm and a diameter of about 1.8-3.2cm. "Compendium of Materia Medica" contains varieties. my country is the origin of Sagittarius, which mainly lives in low-lying paddy fields. Sagittarius is distributed all over the world, and it is edible in China, North Korea, Japan, India, North Korea and other regions. In our country, whenever the supply of vegetables is not in time in winter and spring, arrowroot can be used as one of the main vegetables in the off-season. Arrowhead can not only be eaten as a vegetable, but also has high medicinal and ...
