Non-fried puffed jackfruit and preparation method thereof

Abstract

The invention discloses non-fried puffed jackfruit and a preparation method thereof. The puffed jackfruit is prepared by performing variable temperature and pressure-difference puffing on jackfruit flesh in a puffing tank, wherein the variable temperature and pressure-difference puffing comprises the following steps: 1) raising temperature in the puffing tank to be between 102 and 110 DEG C, raising pressure to be 0.2 to 0.3MPa higher than atmosphere pressure outside the puffing tank, and maintaining the temperature and the pressure so that the surface temperature of the jackfruit flesh is consistent with the temperature in the puffing tank; 2) reducing the pressure in the puffing tank to a vacuum state, reducing the temperature to be between 75 and 85 DEG C in the vacuum state, and then maintaining the pressure and the temperature in the vacuum state to ensure that the water content of the jackfruit flesh is between 3 and 5 percent; and 3) reducing the temperature in the puffing tankto be between 10 and 30 DEG C, and maintaining the temperature for 30 to 60 minutes in the vacuum state to obtain the puffed jackfruit. By the method, coloring matter, other additives and the like are not added in the processing process, the original color and flavor of the fruit are maintained as much as possibly, so the puffed jackfruit is pure and natural, and safe and sanitary.

Description

technical field [0001] The invention relates to a non-fried puffed jackfruit and a preparation method thereof. Background technique [0002] Jackfruit (Artocarpus.heterophyllus.lam.) is a plant of the genus Pineapple in the Moraceae family. Its English names include Jackfruit, Jakfruit, Jaca, Nangka, Jack, Jacquiet, etc. fruit. It is a world-renowned tropical fruit tree, native to India, and currently cultivated in tropical countries such as Myanmar, Thailand, Sri Lanka, Indonesia, the Philippines, Australia, and Bangladesh. China has introduced jackfruit with a history of more than one thousand years, and it is now cultivated in Guangdong, Guangxi, Hainan, Yunnan, Fujian, southern Sichuan, and Taiwan Province of China. Hainan is the most planted, and most other areas are scattered cultivation. [0003] Jackfruit is known as the king of fruits: the fruit is on the trunk. There are countless golden meat buns inside. The flesh is thick without glue, sweet and delicious, and...

Problems solved by technology

At present, the processing technologies of fruit and vegetable chips mainly include vacuum frying, microwave drying and freeze drying. Harmful substances to the human body; although the products processed by microwave drying or freeze drying have good product properties, the cost of processing equipment and energy consumption are relatively large, which is not conducive to the promotion and wide use of technology
