Papaya crisp slices and preparation method thereof

The invention discloses papaya crisp slices and a preparation method thereof. According to the method, the papaya crisp slices are produced by combining a microwave vacuum drying technology and a variable temperature and pressure difference puffing technology. The method comprises the following steps: drying papaya slices in a microwave vacuum manner under the conditions that the vacuum degree is 60kPa-100kPa and the microwave powder is 200W-800W until the water content is 20%-60%; and then putting the papaya slices into a puffing tank for variable temperature and pressure difference puffing, namely raising the temperature of the puffing tank to 60-120 DEG C under a normal pressure, stopping for 10min-30min, instantly reducing the pressure in the puffing tank to -0.01MPa, puffing 1-5 times in a vacuum state, cooling to 60-90 DEG C, keeping the vacuum state and the temperature until the water content of the papaya slices is 4%-5%, then cooling to 40-60 DEG and keeping the vacuum state for 15-45 minutes. The papaya crisp slices produced by the method keep the original color, flavor and nutrition of papayas, have a crispy mouth feel and can be directly used as a snack food and also be used as raw materials for making the papaya into powder. Meanwhile, the drying time is shortened to 3-6 hours by the method; compared with a traditional drying method, the method has the advantages that the efficiency is improved and the energy consumption is reduced obviously.

Shii-take product producing method by combining pressure difference puffing with microwave technology

The present invention relates to a shii-take product producing method by combining pressure difference puffing with microwave technology. The shii-take drying methods are relative many, but are slow in dehydration speed, poor in product quality, large in energy consumption, and more expensive in equipment. The fresh shii-takes are washed, the shii-take caps and stems are separated to form the shii-take raw materials in different states, and Vc aqueous solution is used to soak the shii-take raw materials, and the shii-take raw materials are rehydrated and pre-dried; the pre-dried materials are loaded into a puffing chamber of a pressure difference puffing machine, and are heated, pressurized and subjected to a first puffing; and the temperature is lowered, and the shii-take materials are taken out and further dried by microwave to obtain the finished products. The shii-take products are classified based on the physical and chemical characteristics of the each part of the shii-takes and are puffed under a certain condition to achieve the best quality. By using the rehydration approach while adding Vc antioxidant to protect color, the water content of the shii-takes before the puffing is ensured to be kept consistent as far as possible; and the puffing combined with the microwave technology is conductive for industrial production, and the quality of the various color, flavor, taste and shape aspects of the shii-takes are all significantly improved; and the use of microwave heating mode can effectively shorten the processing time.

Preparation method of leisure dioscorea batatas bean and leisure dioscorea batatas bean prepared by adopting same

The invention provides a preparation method of leisure dioscorea batatas bean and the leisure dioscorea batatas bean prepared by adopting the preparation method. The preparation method is characterized in that processing and preparation are carried out after cooking and freezing and also comprises the steps of pricking holes, seasoning and packaging. The preparation method provided by the invention has the advantages that internal tissues of the dioscorea batatas bean can be softened, moisture inside the tissues can be more beneficially gathered and form ice crystals, particles are enlarged, and holes left by the ice crystals inside the dioscorea batatas bean after reprocessing enable the dioscorea batatas bean to be loose in structure and taste; and meanwhile, a hole pricking method is adopted, so that seasoners can enter the cooked dioscorea batatas bean more easily, burst of the dioscorea batatas bean in a reprocessing process is also reduced, and complete shape of the dioscorea batatas bean is fully maintained. The prepared dioscorea batatas bean remains functional ingredients and taste of the dioscorea batatas bean, is prolonged in quality guarantee period, can be stored and transported at normal temperature and is a convenient and leisure dioscorea batatas bean functional dietary therapy product.
