Problems solved by technology

At present, most camellia seed oils are produced by the traditional hot pressing method, which needs to go through steaming, pressing, refining and other processes. Acid, alkali, activated clay, etc. may cause contact pollution
However, because cold pressing omits the pretreatment process of high-temperature steaming and frying, the oil particles in the raw material are still distributed in the undeformed protein cells of the raw material in a dispersed state, so the oil yield of cold pressing is lower than that of hot pressing

Embodiment 1

[0037] (1) Fruit picking: pick mature camellia oleifera fruit, first stack the camellia oleifera fruit for 5 to 7 days to ripen to increase the oil content, then expose to the sun for 3 to 5 days, and set aside;

[0038] (2) Shelling: adopt sheller to slough off the pericarp and shell of camellia oleifera fruit, for subsequent use;

[0039] (3) Pulverization: pulverize the shelled Camellia oleifera seeds to 10-20 mesh, set aside;

[0040] (4) Enzyme addition: add protease liquid to the pulverized Camellia oleifera seeds at a material-to-liquid ratio of 1:8 (kg / L), the protease activity of the protease enzyme liquid is 800U / mL, and then fully mix evenly;

[0041] (5) Segmented vacuum microwave treatment: transfer the Camellia oleifera seeds obtained through step (4) to a vacuum microwave oven for segmental vacuum microwave treatment; segmental vacuum microwave treatment includes the first section of vacuum microwave treatment and the second section of vacuum microwave treatment...

Embodiment 2

[0046] (1) Fruit picking: pick mature camellia oleifera fruit, first stack the camellia oleifera fruit for 5 to 7 days to ripen to increase the oil content, then expose to the sun for 3 to 5 days, and set aside;

[0047] (2) Shelling: adopt sheller to slough off the pericarp and shell of camellia oleifera fruit, for subsequent use;

[0048] (3) Pulverization: pulverize the shelled Camellia oleifera seeds to 10-20 mesh, set aside;

[0049] (4) Enzyme addition: Add cellulase enzyme liquid to the pulverized Camellia oleifera seeds at a material-to-liquid ratio of 1:12 (kg / L). The cellulase enzyme activity of the cellulase enzyme liquid is 2000U / mL, and then fully well mixed;

[0050] (5) Segmented vacuum microwave treatment: transfer the Camellia oleifera seeds obtained through step (4) to a vacuum microwave oven for segmental vacuum microwave treatment; segmental vacuum microwave treatment includes the first section of vacuum microwave treatment and the second section of vacuum...

Abstract

The invention belongs to the field of vegetable oil processing, and particularly relates to a process for preparing cold-pressed camellia oleosa seed oil by virtue of vacuum microwave enzyme method pretreatment. The process comprises the following procedures: (1) picking fruits; (2) removing husks; (3) crushing; (4) adding enzymes; (5) carrying out staged vacuum microwave treatment; (6) carrying out physical cold pressing; (7) drying; (8) filtering. The process disclosed by the invention can be used for pretreating the camellia oleosa seeds by adopting a staged vacuum microwave enzyme method, is moderate in process condition and can be used for greatly enhancing the oil yield of subsequent cold pressing; the prepared camellia oleosa seed oil has good quality and can be used for better preserving the original nutrition and flavor of the camellia oleosa seed oil.

Description

technical field [0001] The invention belongs to the field of vegetable oil processing, and in particular relates to a process for preparing cold-pressed camellia oleifera seed oil through vacuum microwave enzymatic pretreatment. technical background [0002] With the continuous improvement of people's living standards, Camellia oleifera seed oil, as a natural green health-care nutritional oil product, is more and more favored by consumers. At present, most camellia seed oils are produced by the traditional hot pressing method, which needs to go through the processes of steaming, pressing, and refining. Acids, alkalis, activated clay, etc. may cause contact pollution. [0003] Physical cold pressing is a "green and environmentally friendly" oil production process. It completely adopts a physical and mechanical low-temperature oil production method, which can preserve the original nutrients of camellia oil to the greatest extent, and the camellia seed oil after cold pressing ...
