Embodiment 1

[0025] A preparation method for freeze-dried honey lemon slices, comprising the following steps:

[0026] 1) Primary freezing: the raw materials are stored in the refrigerator to ensure that the raw materials are frozen hard until the machine can be sliced;

[0027] 2) Select the cut head: select the hard lemons obtained in step 1), and remove raw materials and impurities that do not meet the requirements such as rot, stains, and insect damage;

[0028] 3) Cleaning: Clean the qualified raw materials obtained in step 2) with clean water to clean the dirt and foreign matter on the epidermis;

[0029] 4) Disinfection: soak the raw materials obtained in step 3) with 200-250PPM sodium hypochlorite solution for 60 seconds; then rinse with running water for 30 seconds;

[0030] 5) Secondary freeze-drying: drying and hardening the raw materials obtained in step 4), waiting to be sliced;

[0031] 6) Configure honey syrup: use 20% honey, add an appropriate amount of white sugar to dis...

Embodiment 2

[0041] A method for preparing freeze-dried honey lemon slices as described in Example 1, wherein steps 6), 8), 10), 11), and 12) can also adopt the following technical solutions:

[0042] 6) Configure honey syrup: use 10% honey, add appropriate amount of white sugar to dissolve the honey, make the syrup reach the sugar content required by the customer, and then add 1‰ of citric acid to obtain honey syrup;

[0043] 8) Vacuum sugar osmosis: Soak the raw materials obtained in step 7) and the sugar water obtained in step 6) at a ratio of 1.1:1. The soaking effect is mainly based on the lemon slices fully absorbing the sugar water, and the vacuum adsorption is used to absorb the sugar liquid. Control the vacuum degree of 0.15MPa to carry out adsorption for 30 minutes, and the lemon slices after adsorption are left to stand under normal pressure for 60 minutes;

[0044] 10) Quick-freezing: Send the raw materials obtained in step 9) into the quick-freezing warehouse, control the temp...

Embodiment 3

[0048] A method for preparing freeze-dried honey lemon slices as described in Example 1, wherein steps 6), 8), 10), 11), and 12) can also adopt the following technical solutions:

[0049] 6) Configure honey syrup: use 30% honey, add appropriate amount of white sugar to dissolve the honey, make the syrup reach the sugar content required by the customer, and then add 5‰ of citric acid to obtain honey syrup;

[0050] 8) Vacuum sugar osmosis: Soak the raw materials obtained in step 7) and the sugar water obtained in step 6) at a ratio of 1.1:1. The soaking effect is mainly based on the lemon slices fully absorbing the sugar water, and the vacuum adsorption is used to absorb the sugar liquid. Control the vacuum degree of 0.08MPa to carry out adsorption for 40 minutes, and the lemon slices after adsorption are allowed to stand under normal pressure for 40 minutes;

[0051] 10) Quick-freezing: Send the raw materials obtained in step 9) into the quick-freezing warehouse, control the t...

Abstract

The invention provides a preparation method of a freeze-dried honey lemon slice. The freeze-dried honey lemon slice prepared by the method is rich in vitamins, has the effects of whitening and spot banishing, refreshing and restoring consciousness and appetizing, has the inherent color of lemon, is free of other adverse colors and visible impurities and high in transparency, remains the general taste and flavor of lemon and honey, is fresh in flavor, high in plumpness, proper in sour and sweet and coordinative in flavor, tastes a little bitter of lemon, remains the special color, flavor, taste, appearance and various bioactive nutritional components of fresh lemon, and has the same flavor with the new cut fresh lemon. The freeze-dried honey lemon slice contains 130.77KJ of energy, 0.065g of protein, 0.07g of fat, 10.03g of carbohydrate, 7g of dietary fiber, 8gm of sodium and 250mg of vitamin C. The preparation method has an obvious effect; freezing is performed at three times; the product can be further sterilized, so that the safety of the food can be ensured.

Description

technical field [0001] The invention relates to the field of freeze-dried food, in particular to a preparation method of freeze-dried honey lemon slices. Background technique [0002] Lemon slices are divided into dried lemon slices and freeze-dried lemon slices. Freeze-dried lemon slices use the principle of sublimation in a vacuum state to make the moisture in the pre-frozen food sublimate directly into water vapor without melting the ice. Remove, so that the food is dry, rich in vitamins, limonin and other essential nutrients for the human body. It has excellent rehydration property without any additives. It is a good product for tea drinking and cooking seasoning. Dried lemon slices are generally thinner; freeze-dried lemon slices are generally thicker. Freeze-dried lemons are divided into ordinary freeze-dried lemons and honey freeze-dried lemons. [0003] At present, the production process of honey freeze-dried lemon is: raw lemon fruit → acceptance → cleaning → ozon...
