Embodiment 1

[0023] After the harvested banana leaves are removed and the outer skin is peeled off to obtain banana stems, the peeled stems are squeezed and dehydrated with a press machine, and pressed into sheets with a thickness of 10 mm; the squeezed banana stems are thinly sliced ​​on a cutter. Cut into short sections of 0.5mm; dry the cut banana stems with hot air at 60°C for 10 hours, and control the moisture content at 4%; use a pulverizer to crush and sieve the dried materials to obtain bananas Stem powder.

Embodiment 2

[0025] Remove the leaves from the harvested banana trees and peel off the outer skin to obtain the banana stems, press and dehydrate the peeled stems with a press, and press them into sheets with a thickness of 15mm; cut the squeezed banana stems into thin slices on a cutting machine into short sections of 1mm; dry the cut banana stems with hot air at a temperature of 70°C for 8 hours, and control the moisture content at 5%; use a pulverizer to crush and sieve the dried materials to obtain banana stems dry powder.

Embodiment 3

[0027] Remove the leaves from the harvested banana trees and peel off the outer skin to obtain the banana stems, press and dehydrate the peeled stems with a press, and press them into sheets with a thickness of 20mm; cut the squeezed banana stems into thin slices on a cutting machine Cut into short sections of 2 mm; dry the cut banana stems with hot air at 80°C for 6 hours, and control the moisture content at 5%; use a pulverizer to crush and sieve the dried materials to obtain banana stems dry powder.

[0028] The banana stem powder obtained by the preparation method of the invention is light green and has the natural smell of the fragrant banana stem, and can be used as a raw material of dietary fiber.

[0029] In the cutting process, different cutting lengths are the key steps to control the particle size of the powder. The longer the length is, the larger the particle size of the powder is, and the water absorption performance of the powder is inversely proportional to the...

Abstract

The invention relates to a preparation method of banana pseudo stem. The method comprises the following steps: removing leaves from harvested banana trees, stripping off barks to obtain banana pseudo stems, squeezing and dehydrating the banana pseudo stems, cutting the banana pseudo stems by using a cutter, drying the cut banana pseudo stems by using a hot air drying oven, crushing the obtained dried material by a crusher, and sieving to obtain the banana pseudo stem powder.

Description

technical field [0001] The invention relates to the field of agricultural waste reuse, in particular to a method for preparing banana stem powder. Background technique [0002] my country is a big banana planting country, which produces a large amount of banana tree waste resources every year. As a tropical herbaceous crop, banana has the characteristics of fast growth and high biological yield. During the banana harvest season, a large number of banana trees are cut down, and the banana trees are piled up as waste. High content, the rate of decay is very slow. Sun-drenched, necrotic banana stems are easy to nourish pathogens after fermentation. In 2011, only Hainan Province had a planting area of ​​750,000 mu. According to preliminary estimates, 120 banana trees are planted per mu, and each plant can produce 500g of waste (dry basis). It is conservatively estimated that 40,000 to 50,000 tons of banana trees are discarded every year in Hainan alone. The abandonment or bur...
