Problems solved by technology

Patients suffering from high blood pressure, heart disease, hepatitis, and liver cirrhosis often eat some pears. It can promote appetite, help digestion, and has diuretic, laxative and antipyretic effects. It can be used to replenish water and nutrition when high fever. Pineapple There are various ways to eat pineapple. In addition to eating raw, it can also be made into canned food, candied fruit, jam, candy, dried fruit, etc. Dried fruit is one of the processed foods of pineapple. At present, the main index of dried fruit production is the dehydration rate. The dried fruit produced in this way has a hard taste and the pulp fiber is easy to age

Embodiment 1

[0016] Embodiment 1, a kind of selenium-enriched dried pineapple fruit preparation method, specifically:

[0017] (1) After peeling the selenium-enriched pineapple, soak it in the fresh-keeping liquid for 8 minutes. The fresh-keeping liquid uses water as the solvent, and adds 60 micrograms of vitamin K, 2 mg of mucopolysaccharide, 1 mg of green leaf alcohol, and 6 g of cooked starch to each L of water. It is obtained by mixing, and the selenium-enriched pineapple is cut by an ultra-high pressure water cutting method, and the water source in the nozzle is a fresh-keeping liquid, and the selenium-enriched pineapple is cut into strips;

[0018] (2) Send pineapple strips into the centrifuge for variable-speed centrifugal dehydration. The variable-speed centrifugal dehydration implements high-speed and low-speed centrifugal dehydration. The high-speed centrifugal rate is 300r / min, and the low-speed centrifugal rate is 40r / min. High-speed centrifugation and low-speed centrifugation ...

Embodiment 2

[0021] Embodiment 2, a kind of selenium-enriched dried pineapple fruit preparation method, specifically:

[0022] (1) After peeling the selenium-enriched pineapple, soak it in the fresh-keeping liquid for 10 minutes. The fresh-keeping liquid uses water as the solvent, and adds 80 micrograms of vitamin K, 3 mg of mucopolysaccharide, 1.2 mg of green leaf alcohol, and cooked starch to each L of water. 8g is mixed, and the selenium-enriched pineapple is cut by ultra-high pressure water cutting method, the water source in the nozzle is fresh-keeping liquid, and the selenium-enriched pineapple is cut into strips;

[0023] (2) Send pineapple strips into the centrifuge for variable-speed centrifugal dehydration. The variable-speed centrifugal dehydration implements high-speed and low-speed centrifugal dehydration. The high-speed centrifugal rate is 350r / min, and the low-speed centrifugal rate is 50r / min. High-speed centrifugation and low-speed centrifugation are carried out alternatel...

Embodiment 3

[0026] Embodiment 3, a kind of selenium-enriched dried pineapple fruit preparation method, specifically:

[0027] (1) After peeling the selenium-enriched pineapple, soak it in the fresh-keeping liquid for 9 minutes. The fresh-keeping liquid uses water as the solvent, and adds 70 micrograms of vitamin K, 2.5 mg of mucopolysaccharide, and 1.1 mg of green leaf alcohol to each L of water. 7g of starch is mixed, and the selenium-enriched pineapple is cut by ultra-high pressure water cutting method. The water source in the nozzle is fresh-keeping liquid, and the selenium-enriched pineapple is cut into strips;

[0028] (2) Send pineapple strips into the centrifuge for variable-speed centrifugal dehydration. The variable-speed centrifugal dehydration implements high-speed and low-speed centrifugal dehydration. The high-speed centrifugal rate is 320r / min, and the low-speed centrifugal rate is 45r / min. When variable-speed centrifugal dehydration, High-speed centrifugation and low-speed ...

Abstract

The invention belongs to the technical field of fruit processing, and more specifically relates to a manufacturing method of selenium-enriched dried yellow pear. The manufacturing method comprises following steps: selenium-enriched yellow pear are subjected to peeling, are immersed in a fresh-keeping liquid, and are cut into strips via superhigh pressure waterjet cutting; the obtained yellow pear strips are delivered into a centrifuge for speed variable centrifuge dewatering until yellow pear center water content ranges from 30 to 32%; the obtained yellow pear strips are delivered into a high pressure bag, and are subjected to repeat pressurization and depressurization treatment; and obtained yellow pear products are subjected to vacuum packaging and refrigerated preservation at 2 to 5 DEG C. The selenium-enriched dried yellow pear is unique in flavor, is soft and wet in mouthfeel, and is easy to chew.

Description

technical field [0001] The invention relates to the technical field of fruit processing, in particular to a method for preparing dried selenium-enriched pineapple fruit. Background technique [0002] Pineapple is one of the varieties of pears. Its fructose content is as high as 16.8, which is much higher than that of ordinary pears; it is also rich in calcium, iron, zinc, potassium and other trace elements, vitamins B and C, carotene, malic acid, citric acid and other organic acids and fruit acids . These ingredients are very beneficial to humans, especially the asparagine contained in it, which has special health care effects on human health, especially the kidneys. Patients suffering from high blood pressure, heart disease, hepatitis, and liver cirrhosis often eat some pears. It can promote appetite, help digestion, and has diuretic, laxative and antipyretic effects. It can be used to replenish water and nutrition when high fever. Pineapple There are various ways to eat...
