preparation example Construction

[0037] In the present embodiment, the preparation method of described eucalyptus lyophilized powder comprises the following steps:

[0038] S01: Fruit selection: remove immature, damaged or rotten eucalyptus fruits.

[0039] S02: Cleaning: Clean the surface of the fruit, remove the core, slice 0.1cm-2cm, and set aside. Preferably, in the cleaning process, a salt solution with a mass fraction of 2% to 5% can be used for cleaning, and soaked for 5 to 10 minutes. The fresh fruit is fuller and at the same time improves the taste of the plum, making it more flavorful.

[0040] S03: Fixing: the eucalyptus after the step of "cleaning" is placed in water at 100°C for 5 min to 10 min, and the purpose of fixing is to make the eucalyptus fruit taste sweet and not astringent.

[0041] S04: Air-drying: After the step of "fixing green", the eucalyptus is placed under the conditions of 5 ℃ to 20 ℃ and air-dried for 2h to 3h. The purpose of air-drying is to remove the water attached to the ...

Embodiment 1

[0064] Embodiment 1: the preparation of eucalyptus lyophilized powder

[0065] Fruit selection: Eliminate immature, damaged or rotten eucalyptus fruit.

[0066] Cleaning: Clean the surface of the fruit, remove the core, slice 0.1cm-2cm, and set aside.

[0067] Fixing: After the step of "cleaning", the Ou Li was placed in water at 100°C for 5 minutes.

[0068] Air-drying: After the step of "fixing the green", the Ou Li was naturally air-dried under the condition of 5 ℃ for 2 hours.

[0069] Pre-cooling: After the "air-drying" step, the Ou Li is pre-frozen to -60°C in the freezer. The pre-cooling process is as follows:

[0070] (1) Cool down from the initial temperature of pre-cooling to -4°C, the temperature drop rate is 15°C / h, the temperature is lowered to -4°C, and maintained for 1h;

[0071] (2) 0 was cooled from -4°C to -40°C, the temperature decreased at a rate of 10°C / h, and when the temperature dropped to -20°C, -30°C, and -40°C, maintained for 1h respectively;

Abstract

The invention discloses a preparation method of freeze-dried powder of cerasus humilis, and belongs to the technical field of food processing. The method includes the following steps that the cerasushumilis is vaccum freeze-dried and dried under inert gas protection, so that nutrients in cerasus humilis fruits are prevented from oxidative deterioration, gradient slow pre-freezing and gradient slow sublimation processes are adopted, the freeze-dried powder of cerasus humilis is obtained, it is ensured that water in the cerasus humilis fruits is effectively removed, the moisture content of thefreeze-dried powder of cerasus humilis is reduced, and the produced freeze-dried powder of cerasus humilis has excellent color and fluffy degree. The invention further discloses a health-care productprepared from the freeze-dried powder of cerasus humilis, the freeze-dried powder of cerasus humilis and a predetermined proportion of additives are mixed and molded to prepare the cerasus humilis freeze-dried powder health-care product. The obtained cerasus humilis freeze-dried powder health-care product is endurable in storage, easy to transport and good in taste, effectively retains the nutrients of the cerasus humilis fruits and has broad commercial prospects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of eucalyptus freeze-dried powder and a eucalyptus health product. Background technique [0002] European plum (scientific name: Cerasus humilis), also known as calcium fruit, plum, sour Ding, mountain plum, Xiao Liren, etc. The fruit of European plum is red, yellow, purple, bright and attractive, and the fruit is delicious and delicious. It is a high-end urban fruit. the best choice. Ou Li is rich in elements that the human body needs. According to the determination, every 100 grams of Ou Li fresh fruit contains 1.5 grams of protein, 47 mg of vitamin C, 360 mg of calcium, and 58 mg of iron. Ou Li is also rich in sugar, vitamin B, various trace elements and 17 kinds of amino acids necessary for the human body. The edible rate of the fruit can reach more than 90%, the juice yield is about 80%, and the soluble solids are 10%-15%. In partic...
