Processing of pineapple
(1) Process flow
Material selection→ peeling, heart removal→dressing→cutting→protective color, hardening treatment→rinsing→blanching→sugar system→drying→packaging.
(2) Operation points
1 The selection of materials requires maturity of 7 to 80%, except for diseases, insects, and rot.
2 Washing and grading Wash the muddy sand and microorganisms attached to the peel with water, and divide it into three grades according to large, medium and small.
3 peeling, heart-to-heart mechanical or manual peeling, the diameter of the knife and the cylinder should be adapted to the pineapple wood.
4 Trimming with a stainless steel knife to remove the residue and spots on the fruit and look at the net.
5 cuts will be cut into the heart of the pineapple after the peeling heart is less than 5cm in diameter. 1.5 cm thick disc; a diameter of 5 cm or more is first cut into 1.5 cm thick discs, and then divided into fan-shaped pieces.
The heart tissue is dense and can be cut obliquely into 0.5cm oval slices, in addition to sugar.
6 The color-hardened sliced ​​fruit pieces were soaked in 0.1% sodium metabisulfite and 0.5% lime solution for 8 to 12 hours. Then rinse.
7 After blanching the fruit pieces, blanching in boiling water for about 5 minutes, remove the drain.
8 sugar cubes are still hot with 30% white sugar, layered fruit sugar tank marinated, with sugar caps. After 24 hours, the sugar liquid was returned to the pot, and 15% of the saccharification was added to boil and then the seeds were stained for 24 hours. So many times of sugar infiltration, so that the fruit pieces absorb sugar up to 60 ~ 65 ° Bx. Alcohol sugar can be used to replace 45% sucrose.
9 Dry the fruit pieces and drain the sugar liquid, evenly spread the drying sieve, and send it to the dryer to dry at 60-65 ° C, and bake until it is not sticky.
10 packaging PE bags quantitative sealed packaging.
(3) The quality standard is orange-yellow, shiny, translucent, and consistent in color; the appearance is complete, the tissue is full, the surface is dry and not sticky; it has a pineapple flavor. The water content is 18% to 20%; the sugar content is 50% to 60%.
