preparation example Construction

[0025] The invention provides a kind of preparation method of bamboo shoot nutrient powder, comprises the steps:

[0026] 1) crushing: crushing fresh bamboo shoots to obtain wet granules;

[0027] 2) Preheating to kill enzymes: preheating wet granules to get enzyme-killing wet granules, the temperature of the preheating to kill enzymes is 70-95°C, and the time is 1-3 minutes;

[0028] 3) beating: beat the enzyme-inactivated wet granules to obtain a beating liquid, and the dietary fiber particles after beating are less than 40 mesh;

[0029] 4) Pulverization: pulverize the beating liquid for 1 to 3 times;

[0030] 5) Drying: drying the pulverized slurry to obtain bamboo shoot nutritional powder.

[0031] The preparation method of bamboo shoot nutrition powder provided by the present invention preferably includes a pretreatment process: fresh bamboo shoots are shelled, cleaned, and cut into bamboo shoot pieces with a maximum length of 10 cm, and more preferably cut into 2 to 4...

[0047] Preparation of moso bamboo shoot nutrition powder: pick fresh spring bamboo shoots of moso bamboo, after shelling and cleaning, take 1000.0 kg of raw bamboo shoots and add them to a crusher for crushing to obtain 950.0 kg of wet particles of 8 mm. At a temperature of 90°C, after preheating the pipeline for 1.5 minutes to kill the enzyme, it is added to a double-channel beater for beating. The motor speed is 1470 rpm. The sieve aperture is 0.5 mm, and 930.0 kg of beating liquid is obtained. Pass the beating liquid through the colloid mill and continue pulverizing once to obtain 920.0 kg of finer slurry, which is poured into a storage tank with stirring function, and the stirring paddle is turned on. Finally, send the beating liquid in the storage tank into the centrifugal spray dryer with a pump, the flow rate is 100kg / h, the inlet air temperature is 190°C, and the outlet air temperature is 80°C, and 86.5kg of dried bamboo shoot nutrient powder is collected , and the yi...

[0050] Preparation of thunder bamboo shoot nutrition powder: fresh bamboo shoots were picked, shelled and cleaned, and 200.0 kg of raw bamboo shoots were added to a crusher for crushing to obtain 185.0 kg of 6mm wet particles. At a temperature of 90°C, after preheating the pipeline to kill enzymes for 2 minutes, put it into a double-channel beater for beating. The motor speed is 1480 rpm. The mesh diameter is 0.4 mm, and 180.0 kg of beating liquid is obtained. Pass the beating liquid through the colloid mill and continue pulverizing once to obtain 178 kg of finer slurry, which is poured into a storage tank with stirring function, and the stirring paddle is turned on. Finally, the beating liquid in the storage tank is sent into the centrifugal spray dryer with a pump, the flow rate is 80kg / h, the air inlet temperature is 185°C, and the air outlet temperature is 85°C, and 17.5kg of dried bamboo shoot nutrient powder is collected , and the yield was 8.75%.

Abstract

The invention belongs to the technical field of novel food processing, and provides a preparation method for bamboo shoot nutrition powder. The preparation method comprises the following steps: with fresh bamboo shoots as a raw material, shelling the fresh bamboo shoots, then carrying out cleaning and crushing, carrying out preheating for enzyme deactivation, carrying out high-speed double-channelpulping, carrying out pulverizing with a colloid mill, and carrying out centrifugal spray-drying so as to obtain the bamboo shoot nutrition powder. The novel method for directly preparing the bambooshoot nutrition powder from the fresh bamboo shoots provided by the invention has the following advantages: by adoption of the process of crushing, high-speed double-channel pulping and crushing withthe colloid mill, the particle fineness of a pulped liquid is guaranteed; and centrifugal spray drying can be directly carried out, so the bamboo shoot nutrition powder with a particle size of 80-500meshes is obtained by fully utilizing the property that dietary fibers are dried and the water loss particle size is reduced. The bamboo shoot nutrition powder provided by the invention is simple in preparation process, high in processing speed, short in drying time, capable of being continuously produced, high in productivity, fine in powder granularity and suitable for being absorbed by human bodies, is reserved in original fresh fragrance and nutrition of bamboo shoots, is an ideal raw material or additive and a flavor enhancer in foods like biscuits and bread, and can be widely applied tonutrition supplementation in the field of large foods.

Description

technical field [0001] The invention relates to the technical field of novel food processing, in particular to a preparation method of bamboo shoot nutrition powder. Background technique [0002] Bamboo belongs to the perennial evergreen plant of Poaceae, which has the characteristics of fast growth, wide distribution, high biological yield and the ability to produce two main products of bamboo shoots and bamboo wood at the same time. In 2013, the results of the eighth national forest resource inventory showed that my country's existing bamboo forest area was 6.01 million hectares, of which the moso bamboo forest area accounted for more than two-thirds of the total bamboo forest area. There are 39 genera and more than 400 kinds of bamboo plants in my country, accounting for about 1 / 3 of the world's bamboo species resources, mainly grown in Zhejiang, Fujian, Jiangxi, Hunan and other provinces. my country is very rich in bamboo shoot resources, and its output ranks first in t...
