Problems solved by technology

[0004] Due to the direct internal heating of microwave killing, it is easy to cause the oil sac inside the green pepper fruit to be heated and rupture, and the essential oil in the fruit evaporates together with the water
There is also a small amount of essential oil volatilized during the traditional steaming and wok-frying process, but the amount is relatively small, and it is generally not recycled and wasted.

Abstract

The invention discloses a green prickleyash microwave water removing method. The method includes the steps that after being cleaned and drained, green prickleyash is quantitatively bagged through plastic bags and enters a microwave water removing line, microwave heating water removing is conducted, the plastic bags are sealed while the green prickleyash is hot after water removing is completed, microwave sterilization is conducted again, and vacuum-packaged preservative green prickleyash is obtained after cooling is completed. In the microwave water removing process, a large amount of essence-contained steam is generated at high temperature, the steam is led out through an induced draft fan and enters a low-temperature condenser through a pipeline, and condensed and liquefied essence-water mixed liquid is separated through an essence-water separator to obtain green prickleyash essence. Microwave water removing is used, time is short, the effect is good, sterilization can be conducted while water removing is conducted, the green prickleyash variety subjected to water removing through steam originally can be obviously improved, and the fragrance of the obtained green prickleyash essence obtained while microwave water removing is conducted is more similar to the natural fragrance of green prickleyash due to short heating time. The quality of the preservative green prickleyash is improved through the microwave water removing method, the quality of the green prickleyash essence obtained synchronously is more similar to the natural fragrance of the green prickleyash, and the green prickleyash microwave water-removing method has the advantages of being good in water removing effect, low in energy consumption, moderate in operating condition, free of additives and the like.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for greening and keeping green peppercorns fresh by microwave, in particular to realizing the greening and keeping fresh fruits of green peppercorns by adopting microwave heating method. Background technique [0002] Green peppercorns are one of the commonly used food seasonings. Fresh green peppercorns are of the best quality, and fresh green peppercorns are not easy to preserve. Fresh-keeping of green peppercorns becomes a necessary technology. Greening is the core technology of green pepper preservation. The purpose of greening is to deactivate and denature the protein, especially the enzyme, in the middle of green pepper through high temperature, and an irreversible reaction occurs, and the biological enzyme loses its activity irreversibly, so as to achieve the purpose of freshness. [0003] The traditional finishing methods mainly include steam finishing, ...
