Problems solved by technology
The fresh fruit of the miracle fruit that is about to be matured and cleaned is put into the blender, and the purpose of removing the core is achieved by stirring and peeling off the pulp. There are defects such as low pulp yield and easily broken seeds, resulting in bitter taste of the raw material of the miracle fruit, poor appearance, color and quality, lack of Market competitiveness cannot meet the development requirements of large-scale and industrialized miracle fruit processing, which hinders the sustainable development of the miracle fruit planting and processing industry

Embodiment Construction
[0016] The present invention is further described below.
[0017] The skin core separation method of the fresh miracle fruit of the present invention comprises the following steps:
[0018] (1) Select fresh miracle fruit: choose ripe fresh fruit that is free from insects, mildew, rot, damage, bright red color, and large and plump; soak the selected fresh miracle fruit in clean cold boiled water to clean the dust on the surface of the peel , remove the fruiting stems and adulterated leaves.
[0019] (2) Freeze-drying: Spread the cleaned fresh fruit on a tray and pre-cool for about 2 to 4 hours at a temperature of -30 to -40°C; , Freeze-drying for 24 hours or 40 hours under the condition of vacuum degree of 30-50Pa;
[0020] In this step, the pre-cooled fresh fruit can be equilibrated at -35° C. to -45° C. for 20 to 60 minutes before freeze-drying.
[0021] (3) Separation of pulp and core: Take out the freeze-dried fresh fruit and put it into a mesh sieve, and use manual siev...

The invention relates to a husk and kernel separating method for fresh fruits of synsepalum dulcificum, which comprises the following steps of: (1) selecting the fresh fruits of synsepalum dulcificum and soaking the fresh fruits of synsepalum dulcificum into clean cold water to be cleaned; (2) spreading the cleaned fresh fruits in a tray, precooling the fresh fruits at low temperature, placing the fresh fruits into vacuum freeze drying equipment and carrying out freeze drying under the conditions of a temperature of -30 DEG C to -50 DEG C and the vacuum degree of 30 to 50Pa; and (3) taking out the frozen and dried fresh fruits and completely separating fruit pulp from kernels by sieving with a screen, twisting, rubbing and the like. In the husk and kernel separating method for the fresh fruits of synsepalum dulcificum, the fresh fruits of synsepalum dulcificum are treated by a vacuum freeze drying approach and the fruit pulp and the kernels are completely separated by sieving with thescreen, twisting, rubbing and the like. The difficulties of low fruit pul yield, easiness in breaking the seeds, and the like caused after the kernels of the fresh fruits of synsepalum dulcificum areremoved by adopting a conventional method are solved. The product quality of the synsepalum dulcificum is improved.
Description
technical field [0001] The invention relates to a method for peeling and removing cores of plant fruits in the technical field of food processing, in particular to a method for separating the skins and cores of fresh miracle fruits. Background technique [0002] Miracle fruit ( Synsepalum Dulcificum Denill) is a small evergreen shrub belonging to the family Sapotaceae. It is native to West Africa and naturally distributed from West Africa to the Congo. It was introduced to Hainan, Guangdong, Guangxi and Fujian in the 1960s. Because the miraculous fruit pulp contains miraculin, it can change people's sense of taste. If you eat sour food within a few hours after eating miraculous fruit, your taste will become significantly sweeter. Not only can it be eaten fresh, but it can also be made into a food aid for acidic foods. Its taste-changing function allows lemons rich in vitamin C to be taken directly, and it can also be used to prepare weight-loss drugs and appetite-suppressi...
