Problems solved by technology

However, while producing banana food, a large amount of banana peels (accounting for about 30% of the fruit weight) are produced. If a large amount of banana peels are not processed in time, they will pollute the environment and have a negative impact on production.

Embodiment 1

[0022] A method for preparing multifunctional dietary fiber additive from banana peel, is characterized in that, comprises the following steps:

[0023] 1) Choose fresh banana peels: choose fresh banana peels with no browning on the outside;

[0024] 2) Washing with hot water: Rinse the banana peel in hot water at 90°C for 5 minutes, then take out the banana peel;

[0025] 3) Centrifugal drying: Dry the cleaned banana peels with a centrifuge to remove surface moisture and take them out;

[0026] 4) Microwave drying: use a watch glass to take the dried banana peel, put it in a microwave oven to dry for 4 minutes;

[0027] 5) Coarse crushing: the dried banana peels are coarsely crushed into a coarse powder of about 5×5mm by dry crushing method;

[0028] 6) Fine crushing: Use a grinder to finely crush the coarsely crushed banana peels to a powder below 20 mesh;

[0029] 7) Sieving: Sieve the pulverized powder with a 20-mesh standard sieve, and the powder that passes the sieve ...

Embodiment 2

[0031] 1) Choose fresh banana peels: choose fresh banana peels with no browning on the outside;

[0032] 2) Washing with hot water: Rinse the banana peel in hot water at 95°C for 5 minutes, then take out the banana peel;

[0033] 3) Centrifugal drying: Dry the cleaned banana peels with a centrifuge to remove surface moisture and take them out;

[0034] 4) Microwave drying: Use a watch glass to hold the dried banana peel, put it in a microwave oven and dry it for 3 minutes. Under the premise of ensuring smooth crushing, the shorter the drying time, the better. Because the longer the drying time, the darker the color of the product, which affects the appearance of the product;

[0035] 5) Coarse crushing: the dried banana peels are first coarsely crushed into a coarse powder of about 5×8mm by dry crushing method;

[0036] 6) Fine crushing: Use a grinder to finely crush the coarsely crushed banana peels into a powder of about 40 meshes;

[0037] 7) Sieving: Sieve the pulverize...

Abstract

The invention discloses a method for preparing multi-functional dietary fiber additive by using banana skins, which comprises the following steps: 1, selecting fresh banana skins; 2, washing the selected banana skins with hot water; 3, spin-drying: spin-drying the washed banana skins with a centrifugal machine, removing the surface moisture, and taking the banana skin out; 4, microwave drying: putting the dried banana skins on watch glass, placing the watch glass with the dried banana skins into a microwave and drying for 3 to 4 minutes; 5, rough grinding; 6, fine grinding: fine grinding the rough ground banana skins by a grinder into powder with size less than 20 mesh; and 7, screening. According to the method for preparing the multi-functional dietary fiber additive by using the banana skins, a new method for treating the banana skins is provided to recycle waste materials and benefit human beings.

Description

technical field [0001] The invention relates to a method for preparing additives from banana peels, in particular to a method for preparing multifunctional dietary fiber additives from banana peels. Background technique [0002] Banana is the main fruit in the tropics and subtropics, and it has a large output in South China. Bananas are leap-changing fruits, which are difficult to preserve and transport for a long time. With the increase of production, the risk of planting increases sharply. Therefore, deep processing is carried out at the place of origin to produce various banana foods, and a small-scale industrialization has been formed. But when producing banana food, a large amount of banana peels (accounting for about 30% of the fruit weight) are produced. If a large amount of banana peels are not processed in time, they will pollute the environment and have a negative impact on production. [0003] Dietary fiber refers to polysaccharide carbohydrates and lignin that ...
