Problems solved by technology

The disadvantages are: although the frying temperature is lowered to 85°C, it can still destroy the nutrients of fruits and vegetables, especially vitamin C; the oil content of the product is about 20-25%, and the short shelf life of the product is not conducive to later storage
The disadvantage of this method is: the moisture content of the pre-dried fruits and vegetables has an important impact on the product quality. If the moisture content is low, there will not be enough puffing power; if the moisture content is high, the puffed products will not be crispy; 105°C) and stay in the puffing chamber for a long time (50-70min), resulting in a serious loss of nutrients in the product, and the product generally has a burnt or bitter taste
If the waste water is discharged into the surrounding environment without treatment, it will definitely cause serious environmental pollution.
However, to purify wastewater, a large amount of capital needs to be invested, which will undoubtedly greatly increase the production cost of the enterprise.
In order to reduce the cost of sewage treatment, enterprises often directly discharge the blanched waste liquid into the environment after substantial dilution, which further intensifies the consumption and waste of water resources.

Embodiment 1

[0043] A kind of processing method of non-fried apple chips is as follows: ① select 7 mature fresh apples without mechanical damage and insects; 4mm thin slices; ③The sliced ​​apple slices are impacted by high-temperature and high-humidity gas jets for anhydrous blanching to inactivate enzymes. / s, blanching time is 300s; 4. the sucrose solution that concentration is 55% is sprayed on the apple slice after blanching, and containing concentration is 0.4% citric acid in the described sucrose solution; 5. the apple slice after soaking sugar, single The layers are laid flat on the mesh drying tray for gas jet impact drying. The initial drying temperature is 80°C, the initial air velocity is 20m / s, and the drying temperature and air velocity are step by step at each 10°C and 5m / s. Reduce to 60°C and 10m / s, divided into three drying stages, each drying stage 30~90min, stop drying when the moisture content of the apple slices on a wet basis drops to 3.2%; ⑥ Immediately dry the dried ...

Embodiment 2

[0045] A kind of processing method of non-fried apple chips is as follows: 1. Pick 8 mature fresh apples without mechanical damage and moth-eaten; , use a slicer to cut the apples into thin slices with a thickness of 3 mm; ③ impact the sliced ​​apple slices with high-temperature and high-humidity gas jets for anhydrous blanching to inactivate enzymes. The relative humidity is 15%, the air velocity is 6m / s, and the blanching time is 60s; ④ put the blanched apple slices into the sucrose solution with a concentration of 20% (w / v) at room temperature, and soak them for 60min. The above sucrose solution contains citric acid with a concentration of 2.0%; ⑤ put the apple slices soaked in sugar in a single layer on a mesh drying tray for gas jet impact drying at a drying temperature of 50°C and an air velocity of 20m / s , Stop drying when the moisture content of the apple slices on a wet basis drops to 2.0%; ⑥ Air-cool the dried apple slices to room temperature immediately, weigh them ...

Embodiment 3

[0047] The production steps are as follows: ①Select 9 ripe fresh Fuji apples without mechanical damage and insects; ②Rinse the selected apples with tap water to clean the foreign matter on the surface, and use a slicer to cut the apples into thin slices with a thickness of 6mm; ③Sliced ​​apple slices are impacted with high-temperature and high-humidity gas jets for anhydrous blanching to inactivate enzymes. The blanching time is 240s; ④Put the blanched apple slices at room temperature in a sucrose solution with a concentration of 30% (w / v), and soak for 40 minutes. The sucrose solution contains citric acid with a concentration of 1.6%. After the sugar can be seasoned according to the taste of the product design; ⑤ Spread the apple slices soaked in sugar in a single layer on a mesh drying tray for gas jet impact drying at a drying temperature of 80°C and an air velocity of 6m / s. Stop drying when the moisture content of the apple chips drops to 3.0%; ⑥ Air-cool the dried apple c...

Abstract

The invention relates to the field of a leisure instant food processing technology, and particularly relates to non-fried apple chips and a processing method thereof. The processing method comprises the following steps of: selecting, washing and slicing, blanching and inactivating enzyme, soaking sugar, drying and cooling. According to the processing method disclosed by the invention, a non-fried production method is adopted and high-temperature and high-humidity gas jet impacting blanching enzyme inactivation is adopted to avoid a serious problem of nutrition loss caused by hot water blanching; the sugar soaking is adopted to process and protect the color so that a problem of over high sulfur content caused by chemical reagents odium sulfite and sodium pyrosulfite adopted in the traditional method is avoided. The produced non-fried apple chips having the advantages of no oil, low caloric value, long shelf life, intense original fruit flavor, bright color, uniform puffing and crisp texture are useable as a leisure instant food.

Description

technical field [0001] The invention relates to the technical field of leisure ready-to-eat food processing, in particular to a non-fried apple crisp and a processing method thereof. Background technique [0002] Apple is the fruit of the apple tree belonging to the Rosaceae apple subfamily. It originated in Europe and was introduced to China in the nineteenth century. Apple is also called snake fruit in Hong Kong and other places, but it is not because it is the forbidden fruit that the snake lured Eve and Adam to eat in the Bible, but because when importing apples from abroad, some people heard foreigners praise apple delicious (delicious), misunderstood It is thought that this is the foreign name of apple, so it is also called "Dili Delicious Fruit", or Delicious Delicious Fruit for short. Apples are rich in nutrients. According to measurements, every 100 grams of apples contains 6.5-11.2 grams of fructose, 2.5-3.5 grams of glucose, and 1.0-5.2 grams of sucrose. It also ...
