Problems solved by technology

[0003] Currently in production, dragon fruit seeds are separated from the pulp by a beater, and a large amount of viscous substances adhere to the surface, and some pulp components are mixed in them. These viscous components include pectin, viscous polysaccharides, It cannot be washed off with ordinary washing methods, and the fibrous substances in it are more difficult to clean

Embodiment 1

[0020] (1) Wash 20kg of dragon fruit, remove dices, end, cut into pieces, remove the rotten part, and separate the pulp from the peel;

[0021] (2) the pulp is beaten, and the pitaya seeds are sifted out, i.e. 1kg of thick pitaya seeds;

[0022] (3) 1kg of water and 10g of citric acid are added to the thick dragon fruit seeds, stirred evenly and dissolved, then reacted at 100°C for 60min, filtered to obtain dragon fruit seeds without viscous substances on the surface;

[0023] (4) The pitaya seeds are cleaned, and dried with hot air (80° C. at a temperature) to make the moisture content below 5%, to obtain 0.9 kg of dried pitaya seeds, which can then be packaged.

Embodiment 2

[0025] (1) Wash 25kg dragon fruit, remove dices, end, cut into pieces, remove the rotten part, and separate the pulp from the peel;

[0026] (2) the pulp is beaten, and the dragon fruit seeds are sieved out, i.e. the thick dragon fruit seeds 2kg;

[0027] (3) 20kg of water and 200g of citric acid are added to the thick pitaya seeds, stirred evenly and dissolved, then reacted at 125°C for 5min, and filtered to obtain the pitaya seeds;

[0028] (3) 20kg water, 30g citric acid and 2g vitamin C are added in the thick dragon fruit seed, stir evenly and make it dissolve, add the cellulase of 30g, hemicellulase, pectinase again, then at 40 ℃ React for 40min, filter to get the pitaya seeds without viscous substance on the surface;

[0029] (4) the pitaya seeds are cleaned, and microwave drying is adopted to make the water content below 5%, to obtain 1.8kg of dried pitaya seeds, which can then be packaged.

Embodiment 3

[0031] (1) Wash 20kg of dragon fruit, remove dices, end, cut into pieces, remove the rotten part, and separate the pulp from the peel;

[0032] (2) the pulp is beaten, and the dragon fruit seeds are sieved out, i.e. the thick dragon fruit seeds 2kg;

[0033] (3) 7.5kg of water and 750g of citric acid are added to the thick dragon fruit seeds, stirred evenly and dissolved, then reacted at 115°C for 30min, and filtered to obtain dragon fruit seeds without viscous substances on the surface;

[0034] (4) the pitaya seeds are cleaned, and microwave drying is adopted to make the water content below 5%, to obtain 1.8kg of dried pitaya seeds, which can then be packaged.

Abstract

The invention discloses a cleaning disposal method of dragon fruit seed surface, which comprises the following steps: (1) separating fruit and peel of dragon fruit, (2) pulping fruit, sieving coarse dragon fruit seed, (3) adding coarse dragon fruit seed and citrate in the coarse dragon fruit seed, stirring, reacting, filtering to obtain dragon fruit seed.

Description

technical field [0001] The invention relates to the technical field of pitaya seed treatment and processing technology, in particular to a pitaya seed treatment and processing method. Background technique [0002] Pitaya, also known as red dragon fruit, is a fruit cultivar of the genus Hylocereus undatus in the family Cactaceae. It originates in tropical Central America such as Brazil and Mexico. Dragon fruit pulp contains a lot of black, sesame-like dragon fruit seeds, which are rich in nutrients and rich in unsaturated fatty acids, which are very beneficial to the human body. [0003] Currently in production, dragon fruit seeds are separated from the pulp by a beater, and a large amount of viscous substances adhere to the surface, and some pulp components are mixed in them. These viscous components include pectin, viscous polysaccharides, It cannot be washed off with ordinary washing methods, and the fibrous substances in it are more difficult to clean. The existence of ...
