Problems solved by technology

However, the square bamboo shoot powder processed by the traditional technology is not only low in solubility and poor in rehydration, but also often cannot inactivate polyphenol oxidase during processing due to immature technology, resulting in enzyme browning during processing and storage, affecting In addition, there are problems of long drying time and low efficiency in the drying process

Embodiment 1

[0026] A preparation method of square bamboo shoot powder, the method may further comprise the steps:

[0027] a. Harvesting of raw materials: within 2 to 6 days after the rain from mid-September to early October every year, take square bamboo shoots with a length of 15 cm after unearthed as raw materials, and dig out 5 cm of soil at the base of the bamboo shoots when digging and break them off;

[0028] b. Blanching: remove the mud and wash the excavated square bamboo shoots, and put them in water with a temperature of 89°C for 3 minutes;

[0029] c, cooling: put the square bamboo shoots after blanching into the air-permeable basket, and place them in a cold storage where the temperature is 3°C and the relative humidity is 85%, so that the temperature of the bamboo shoots drops to 15°C rapidly;

[0030] d. Shelling: first divide the bamboo shoot tip into two halves with a knife, then roll half of it with your fingers or chopsticks, and roll it outward until the bamboo shoot s...

Embodiment 2

[0036] A preparation method of square bamboo shoot powder, the method may further comprise the steps:

[0037] a. Harvesting of raw materials: within 2 to 6 days after the rain from mid-September to early October every year, take square bamboo shoots with a length of 16 cm after unearthed as raw materials, and dig out 5 cm of soil at the base of the bamboo shoots when digging and break them off;

[0038] b. Blanching: remove the mud and wash the excavated square bamboo shoots, and put them into water with a temperature of 90°C for 4 minutes;

[0039] c, cooling: put the square bamboo shoots after blanching into the air-permeable basket, and place them in a cold storage where the temperature is 4°C and the relative humidity is 87%, so that the temperature of the bamboo shoots drops to 16°C rapidly;

Abstract

The invention discloses a preparation method of chimonobambusa quadrangularis bamboo shoot powder. The method comprises the following steps: raw material harvesting, blanching, cooling, shelling, splitting, microwave drying, superfine grinding, and packaging for storage. By virtue of the process and technical parameters of a blanching technology, a microwave drying technology and a superfine grinding technology, the solubility, reconstitution property, mouthfeeling and quality of the chimonobambusa quadrangularis bamboo shoot powder can be improved, the production technology difficulty of the chimonobambusa quadrangularis bamboo shoot powder can be solved, and the benign development of chimonobambusa quadrangularis bamboo shoot industry can be promoted.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of square bamboo shoot powder. Background technique [0002] Square bamboo is a plant of the genus Phyllostachys genus of the Poaceae Bamboo subfamily. It mainly grows in plateau mountainous areas at an altitude of 1400 meters to 2500 meters. It is square in shape, with edges and corners. A rare thing that grows from aura. Square bamboo shoots contain trace elements such as iron, copper, zinc, manganese, selenium, etc., and macro elements such as phosphorus, potassium, calcium, magnesium, and sodium, which are necessary for human body. Compared with other vegetables, the content of potassium, iron, manganese, zinc, copper and other mineral nutrients in square bamboo shoots is respectively the average content of potassium, iron, manganese, zinc and copper in root vegetables (radish, carrot, lotus root, etc.). 2.6 times, 9.7 times, 8.5 times, 3.3 time...
