Description
Technical field
The present invention relates to a kind of food preservative, particularly a kind of leafy vegetable antistaling agent that can prevent from vegetables from going bad degenerating.
Background technology
Leafy vegetable is large due to leaf moisture, apt to deteriorately degenerates, and can not preserve for a long time.Current supermarket, in order to fresh-keeping, be generally wrapped up by vegetables with plastic sheeting, preserve.Like this, although prevent the evaporation of leaf moisture, vegetables are easily made to go bad.
Summary of the invention
The object of the present invention is to provide and a kind ofly can extend leafy vegetable storage life and the leafy vegetable antistaling agent preventing vegetables rotten.
The present invention is realized by following measures
The invention discloses a kind of leafy vegetable antistaling agent, make by the following method:
(1) dry for 1Kg sea-tangle is fully soaked, the segment of about 5cm is cut into after removing silt, maintain under 1.0MPa pressure and carry out Steam explosion treatment in 10 minutes, sea-tangle after process adds 10L2% (weight) sodium carbonate liquor again, maintain 45 DEG C of digestion 1 hour, add 10Kg water, be separated after stirring, discard residue, get thickness supernatant and be sodium alginate gel solution;
(2) 10Kg water is got, add a certain amount of sea-mussel mucin, mint extract, pectin, Sodium Benzoate, Folium Forsythiae extract, gamma-polyglutamic acid-(γ-PGA), copper sulphate, stir, make drug solution, make its content reach sea-mussel mucin 5g/l, mint extract 10g/l, pectin 10g/l, Sodium Benzoate 1g/l, Folium Forsythiae extract 10g/l, gamma-polyglutamic acid-10g/l, copper sulphate 3g/l respectively;
(3) above-mentioned sodium alginate gel solution and drug solution mix for the ratio of 1:2 by volume, stir, make leafy vegetable antistaling agent.
Leafy vegetable antistaling agent of the present invention, in order to improve bactericidal effect, described mint extract extracts from peppery peppermint, and extracting method at 40-50 DEG C of temperature, adds 8-10 times of water extraction get and make.
Leafy vegetable antistaling agent of the present invention, in order to improve bactericidal effect, the preparation of described Folium Forsythiae extract Folium Forsythiae extract: getting fresh Folium Forsythia at room temperature airing to water content is 30%-40%, afterwards, put into crusher for crushing to 30-60 order, then, Folium Forsythia after pulverizing is placed in microwave dryer, account for the condition of the inner free space 1/3 ~ 1/2 of microwave dryer at the Folium Forsythia volume putting into microwave dryer under, adjustment microwave power is 700 ~ 900W, microwave treatment 50 ~ 80s, then, the Vc solution that mass concentration is 0.1-0.15% is added in the Folium Forsythia after microwave treatment, the ratio of weight and number of the Folium Forsythia after added Vc solution and microwave treatment is 5-7:1, afterwards, heating digestion is the 1/3-1/2 of digestion front volume to the volume of mixture, digestion terminates rear filtration, get filtrate, for subsequent use, adopt volumetric concentration be 55% ethanol lixiviate is carried out to the filter residue that obtains after filtering, during lixiviate, every 1g Folium Forsythia uses 30mL ethanol, after lixiviate terminates, the filtrate obtained after the leaching liquor obtained and digestion being filtered merges, and leaves standstill, and filters, at 50 DEG C, reduced pressure concentration reclaims ethanol, obtain concentrate, room temperature leaves standstill, and filters, obtain Folium Forsythia extract, afterwards, by the Folium Forsythia extract transposition that obtains in vacuum freeze drier inner drying 48h, solid forsythia suspense extraction is namely obtained.
Leafy vegetable antistaling agent of the present invention, in order to improve bactericidal effect, described gamma-polyglutamic acid-source is made for the lichen bacillus ferments extracts.
Matrix of the present invention adopts sodium alginate gel solution, utilizes the feature of its good film-forming property, can form layer protecting film fast at vegetable surface, stops bacterium to enter vegetable surface.
Gamma-polyglutamic acid-is a kind of multidentate ligand, and it contains the atom that ammonia nitrogen and carboxyl oxygen two have strong coordination ability, is applicable to the complexing of metal ion containing unoccupied orbital with copper ion etc., has the function of certain kill bacteria.
Sea-mussel mucin is a kind of secretion byssus of marine mussel, has high strength, high tenacity and high water proofing property.Sea-mussel mucin mainly uses medical function after being extracted by modern biotechnology.The present invention uses sea-mussel mucin, and one is the bond properties utilizing it superpower, can form a closely knit protective layer rapidly at the vegetable surface cut, and prevents outside bacterium from entering vegetables.Two is functions that sea-mussel mucin also has certain kill bacteria.
The present invention adds a certain amount of mint extract, pectin, Sodium Benzoate, Folium Forsythiae extract, and one is the function that can play good kill bacteria.Two is fresh, the tasty and refreshing effects that can keep vegetables, and three is the faint scents that can increase vegetables.
Antistaling agent using method of the present invention is be placed on by antistaling agent in container, and add 2-3 water doubly, mixing, by leafy vegetable, soaks in antistaling agent, takes out, drains away the water, get final product room temperature preservation.
During use, leafy vegetable there is is clear water wash clean, antistaling agent can be removed.
Leafy vegetable antistaling agent of the present invention is all extract from natural material substantially, no side effects; layer protective layer can be formed on surface; suppress generation and the breeding of spoilage organisms, prevent the rotten of leafy vegetable, the freshness of leafy vegetable can be kept the long period.
