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
The present invention relates to a kind of manufacture craft of lemon tablet, particularly the manufacture craft of the bright sheet of a kind of lemon.
Background technology
Lemon is rich in various trace elements such as vitamin C, citric acid, malic acid and calcium, iron, zinc, is the healthy food of the low sodium of a kind of high price, has effects such as heat-clearing, step-down, moist beauty treatment, liked by masses.But the lemon fresh fruit is preserved difficulty because cutting easy brown stain, carries problems such as inconvenience, and is subjected to the restriction in season and place, can not satisfy people's demand.People adopt to preserve being dried to dried lemon tablet after the lemon section at present, lemon is in being processed into the process of dried lemon tablet, and vitamin C can heavy losses, and lemon and anthocyanidin also can partial losses, though keep the tart flavour of lemon, main nutrient composition all can be damaged.Therefore seek a kind of nutritional labeling that can preserve lemon, can not make the processing technology of lemon tablet of peaceful door brown stain become insider's pursuing target again.
Summary of the invention
Purpose of the present invention just is to provide a kind of nutritional labeling that can keep lemon, can not cause the manufacture craft of the bright sheet of lemon of lemon brown stain again.
For achieving the above object, the present invention is achieved in that the manufacture craft of the bright sheet of a kind of lemon, and this technology comprises the steps:
(1) lemon is really selected;
(2) seed is really cleaned, cuts into slices, gone to the lemon of picking out;
(3) protect look, the lemon tablet that removes seed is put into the solution that the anti-oxidant anti-enzymatic regent that can eat is made into soak;
(4) vacuum-packed, sterilization obtains the bright sheet of lemon.
Adopt technique scheme, the lemon sheet that removes seed soaked in the anti-oxidant anti-enzymatic regent that can eat protect look, and then with the vacuum-packed sterilization of the bright sheet of lemon, kept the nutrition of the bright sheet of lemon like this, also avoided the bright sheet of lemon by brownization, and the present invention does not add any anticorrisive agent in the bright sheet of lemon, meet present people's consumption concept, and the bright sheet of lemon of health-nutrition is provided to consumers in general.
In technique scheme, processing for convenience and edible: the thickness of described lemon tablet is 2-3mm.
In technique scheme, for the bright sheet of lemon being played the effect of better anti-brown stain, described anti-oxidant anti-enzymatic regent is the L-cysteine, and the mass concentration of described L-cysteine solution is 0.05%-0.2%, and the time of immersion is 1-2min.
In technique scheme, for the bright sheet of lemon being played the effect of better anti-brown stain, described anti-oxidant anti-enzymatic regent is disodium ethylene diamine tetraacetate, and the mass concentration of described disodium ethylene diamine tetra-acetic acid solution is 0.1%-0.5%, and the time of immersion is 1-2min.
In technique scheme: described sterilization process is: the bright sheet of the lemon blanching 20-40s in boiling water with vacuum packet installs, cool off rapidly then, dry.Sterilization process of the present invention does not use sterilizations such as ozone, more meets health idea.
In technique scheme: the packaging bag of described lemon tablet is the aluminium foil vacuum packaging bag.
The invention has the beneficial effects as follows: technology of the present invention is simple, cost of manufacture is low, has both preserved the nutritional labeling of the bright sheet of lemon, has avoided the bright sheet of lemon by brownization again, and the present invention does not add any anticorrisive agent, meets present consumer's health idea.
The specific embodiment
Embodiment 1: select that fresh nothing is rotted, the lemon of no disease and pest, lemon is cut into the lemon thin slice of 2-3mm, remove the lemon seed in the lemon tablet; Protect look then, protecting used in the look process is edible antioxygen chemoprevention brown stain solution, and this solution is that mass concentration is the L-cysteine solution of 0.05%-0.2%, the lemon tablet that removes seed is put to L-cysteine solution soaked 1-2min; Take out the lemon tablet that soaks, in its aluminium foil vacuum packaging bag of packing into, vacuumize, seal.Then packaged lemon tablet is put to the water of boiling, blanching 20-40s, cooling is dried rapidly, and storage obtains the bright sheet of lemon.
Embodiment 2: select that fresh nothing is rotted, the lemon of no disease and pest, lemon is cut into the lemon thin slice of 2-3mm, remove the lemon seed in the lemon tablet; Protect look then, protecting used in the look process is edible antioxygen chemoprevention brown stain solution, and this solution is that mass concentration is the disodium ethylene diamine tetra-acetic acid solution of 0.1%-0.5%, the lemon tablet that removes seed is put to disodium ethylene diamine tetra-acetic acid solution soaked 1-2min; Take out the lemon tablet that soaks, in its aluminium foil vacuum packaging bag of packing into, vacuumize, seal.Then packaged lemon tablet is put to the water of boiling, blanching 20-40s, cooling is dried rapidly, and storage obtains the bright sheet of lemon.
