Problems solved by technology

However, fresh lemon fruit is subject to season and place restrictions due to the problems of easy browning when cut open, difficulty in storage, inconvenience in carrying, etc., and cannot meet people's needs.
At present, people use sliced ​​lemons and then dry them into dried lemon slices for preservation. During the process of processing lemons into dried lemon slices, vitamin C will be seriously lost, and lemon essential oils and anthocyanins will also be partially lost. Although the sour taste of lemons is retained , but the main nutrients will be destroyed

Embodiment 1

[0017] Embodiment 1: select fresh lemons without rot and no damage by diseases and insect pests, cut the lemons into thin slices of 2-3mm, and remove the lemon seeds in the lemon slices; Browning solution, the solution is L-cysteine ​​solution with a mass concentration of 0.05%-0.2%, put the seeded lemon slices into the L-cysteine ​​solution and soak for 1-2min; take out the soaked lemon slices , put it into an aluminum foil vacuum packaging bag, vacuumize it, and seal it. Then the packaged lemon slices are put into boiling water, blanched for 20-40 seconds, rapidly cooled, dried, and stored to obtain fresh lemon slices.

Embodiment 2

[0018] Embodiment 2: select fresh lemons without rot and no damage by diseases and insect pests, cut the lemons into thin slices of 2-3mm, and remove the lemon seeds in the lemon slices; Browning solution, the solution is a disodium edetate solution with a mass concentration of 0.1%-0.5%, put the seeded lemon slices into the disodium edetate solution for 1-2min; take out the soaked Lemon slices, put them in an aluminum foil vacuum bag, vacuumize, and seal. Then the packaged lemon slices are put into boiling water, blanched for 20-40 seconds, rapidly cooled, dried, and stored to obtain fresh lemon slices.

Abstract

The invention discloses a process for making fresh lemon slices. The method comprises the following steps of: (1) selecting lemon fruits; (2) cleaning the selected lemon fruits, slicing, and seeding; (3) protecting the color, namely putting seeded lemon slices into a solution which is prepared by using an edible oxidation-resistant anti-browning agent, and soaking; and (4) performing vacuum packaging, and sterilizing to obtain the fresh lemon slices. The seeded fresh lemon slices are soaked in the solution which is prepared by using the edible antioxidant anti-browning agent for color protection, and then are subjected to vacuum packaging and sterilization, so that the nutrition of the fresh lemon slices is retained, and the fresh lemon slices are prevented from being browned; and additives are not added into the fresh lemon slices, so that the consumption concept of people is met, and the healthy and nutritional fresh lemon slices are provided for broad consumers.

Description

technical field [0001] The invention relates to a production process of lemon slices, in particular to a production process of fresh lemon slices. Background technique [0002] Lemon is rich in vitamin C, citric acid, malic acid, calcium, iron, zinc and other trace elements. It is a high-priced and low-sodium healthy food. But the lemon fresh fruit is subject to the restriction of season and place because of the easy browning of cutting, the difficulty of preservation, and the inconvenience of carrying, which cannot satisfy people's needs. At present, people use sliced ​​lemons and then dry them into dried lemon slices for preservation. During the process of processing lemons into dried lemon slices, vitamin C will be seriously lost, and lemon essential oils and anthocyanins will also be partially lost. Although the sour taste of lemons is retained , but the main nutrients will be destroyed. Therefore looking for a kind of processing technology that can not only preserve t...
