Description

Composite puffed food containing fingered citron functional components and preparation method thereof
Technical Field
The invention belongs to the technical field of food, and particularly relates to composite puffed food containing fingered citron functional components and a preparation method thereof.
Background
The puffed food is also called extruded food, spray puffed food, light food, etc. It is made up by using grain, potato and bean as main raw material, and making them undergo the processes of pressurization and heating treatment to make the volume of raw material self-expand and change internal structure, and making them pass through the processes of processing and forming.
After the grains are placed in the puffing device, along with the pressurization, the moisture in the grains is in an overheated state, the grains are soft, when the high pressure reaches a certain high pressure and the cover of the puffing device is opened, the high pressure is quickly changed into normal pressure, the moisture in the overheated state in the grains is instantly vaporized, water molecules can expand by about 2000 times, the external form of the grains is damaged by the huge expansion pressure, the internal molecular structure of the grains is also broken, the insoluble long-chain starch is cut into water-soluble short-chain starch, dextrin and sugar, so that the insoluble substances in the puffed food are reduced, and the water-soluble substances are increased.
The puffing technology can ensure that starch is completely gelatinized (the gelatinization means that raw starch in food, namely beta starch is changed into alpha starch), the changed alpha starch cannot be recovered into the beta starch after being placed, so that the food keeps soft, good flavor and higher digestibility, and the puffing technology has another characteristic superior to other physical processing methods and opens up a new processing field for coarse grain fine culture. Thus, the nutrient loss is small and easy to digest and absorb: the puffing technology not only changes the appearance of the grains, but also changes the internal molecular structure, and the vitamins of the grains are damaged less (for example, the contents of the vitamins Bl and B6 are obviously higher than those of the cooked foods); the puffing technology can make starch be completely cooked, and the puffed food is porous, so that it is easy to be absorbed by human body.
The bergamot fruit is also named as bergamot, devil claw, five-finger orange and bergamot, is a medicinal and edible raw material, has the effects of reasonably gasifying phlegm, stopping vomiting, relieving flatulence, soothing liver, tonifying spleen, harmonizing stomach and the like, has the relieving effect on tracheitis and asthma of old people, and has better curative effect on dyspepsia and chest and abdominal distension of common people. At present, the main processing modes comprise slicing to prepare dry products for medicine and pickling to prepare preserved fruits. The preserved fruit is called as aged fragrant yellow, is one of three treasures in Chaozhou, and is the first of the three treasures in Chaozhou, and the aged fragrant yellow in Chaozhou in 2018 is successfully declared to be a national geographical marking product. The popularity of the old fragrant yellow is also increasing, and the old fragrant yellow becomes the first choice for tourists from the four seas of the five lakes to purchase special products of Chaozhou, and the memorial archway becomes the old fragrant yellow street. The old fragrant yellow also becomes the first of the Chaozhou Sanbao. The old yellow incense is more a memory of thinking of overseas Chinese and overseas, a cultural symbol. The Chaozhou old fragrant yellow beautiful name is a name card for Chaozhou food and even Chaozhou travel. The old fragrant yellow products mainly take preserved fruits as main materials, the development of the old fragrant yellow industry is seriously influenced, in recent years, although there are reports about processing the old fragrant yellow into products such as beverages, candies, moon cakes and the like, the processed products basically simply add the old fragrant yellow into corresponding products, the functional characteristics of the old fragrant yellow products cannot be well embodied, and the products cannot be accepted by the market basically.
However, at present, fewer puffed foods with functional components exist, and the development of a composite puffed health-care food taking fingered citron and old yellow incense as main raw materials is urgently needed.
