[0012]

Embodiment 2

[0014] In this embodiment, except that the 0.5 g / L sodium hypochlorite solution was used to soak the pineapple for 4 minutes, all the other process steps and process parameters were the same as in Example 1.

Embodiment 3

[0016] Select 800kg of wood pineapple that is disease-free, non-rotten and nearly mature, cut open the wood pineapple, dig out the fruit buds, then cut open the fruit buds, remove the core and leave the meat; wash the wood pineapple meat three times with running drinking water, wash the broken pieces Chips, cut into chunks; soak in 5g / L hydrogen peroxide solution for 3 minutes, rinse with drinking water, drain, put on a plate, and freeze to -35°C; then put the frozen wood pineapple into the freezer vacuum Freeze-dried wood pineapple is obtained after drying in the drying chamber of the dryer, and the parameter control in the freeze-vacuum dryer is shown in Table 2.

Abstract

The invention discloses a method for preparing freeze-dried jackfruit. The method comprises the following operation steps of: firstly, selecting disease-free, decay-free and deterioration-free jackfruit in the maturity of over 80 percent, slivering the jackfruit and excavating fruit bracts; secondly, slivering the fruit bracts, stoning and remaining flesh; thirdly, washing the flesh with flowing drinking water for removing impurities; fourthly, cutting the flesh into blocks; fifthly, sterilizing the jackfruit flesh by using a disinfectant for fruit and vegetable, rinsing clean with the drinking water, and draining away water; sixthly, freezing the jackfruit flesh to the temperature of between -28 to -45 DEC G; and finally, placing the frozen jackfruit flesh into a vacuum freezing dryer, and controlling the vacuum degree to be between 26 and 72 Pa, the cold hydrazine temperature to be between -40 and -60 DEG C, the temperature of a heating plate to be between 50 and 95 DEG C and the drying time to be 8 to 6 hours to obtain the freeze-dried jackfruit. The freeze-dried jackfruit product prepared by the method of the invention does not shrink, and can substantially maintain the color,the flavor and the nutrient components of a fresh fruit.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing freeze-dried wood pineapple by using freeze-drying technology. Background technique [0002] The pulp of jackfruit is sweet and aromatic. Another name: jackfruit. Its fruit pulp is rich in nutrients, containing 20.5%-21.7% of total sugar, 10.5%-17.2% of protein, 0.6% of fat, 23.4% of carbohydrates, and 0.5% of ash. 1.8% fiber; the seeds contain 38.4% carbohydrates, 6.6% protein, 0.4% fat, 1.5% fiber, and 51.6% moisture. disease. [0003] According to the relevant literature, it is found that except for fresh wood pineapple, there are only reports of jackfruit crisps prepared by frying, and no freeze-dried wood pineapple products have been seen yet. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a preparation method for freeze-dried wood pineapple using freeze-drying technology, so tha...
