Description
Technical field
The present invention relates to a kind of food preservative, particularly a kind ofly can prevent the fresh-keeping agent of watermelon degenerated of cutting open a watermelon.
Background technology
Watermelon is the most edible melon and fruit in summer, but due to watermelon comparatively large, once can not eat up, often will place a period of time and eat again.At this time, watermelon surface can produce certain bacterium, even can go bad.Someone can stick one deck plastic foil on the watermelon surface of cutting, and does not in fact also stop the generation of bacterium.
Summary of the invention
The object of the present invention is to provide a kind of can effectively prevent from cutting open a watermelon produce bacterium, prevent the fresh-keeping agent of watermelon that degenerates.
The present invention is realized by following measures,
The invention discloses a kind of fresh-keeping agent of watermelon, 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, ascorbic acid, L-vitamin C, Folium Forsythiae extract, beeswax, Sodium Benzoate, gamma-polyglutamic acid-(γ-PGA), copper sulphate, stir, make drug solution, make its content reach sea-mussel mucin 20g/l, mint extract 10g/l, ascorbic acid 3g/l, L-vitamin C3g/l, Folium Forsythiae extract 10g/l, beeswax 10g/l, Sodium Benzoate 4g/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 1:1 by volume, stir, make fresh-keeping agent of watermelon.
Fresh-keeping agent of watermelon of the present invention, in order to improve its 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.
Fresh-keeping agent of watermelon of the present invention, in order to improve its bactericidal effect, the preparation of described 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.
Fresh-keeping agent of watermelon of the present invention, in order to improve its 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, stop bacterium to enter watermelon surface on watermelon 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, rapidly at the protective layer that the watermelon surface formation one of cutting is closely knit, prevent outside bacterium from entering watermelon.Two is functions that sea-mussel mucin also has certain kill bacteria.
The present invention adds a certain amount of mint extract, ascorbic acid, L-vitamin C, 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 watermelon, and three is the faint scents that can increase watermelon.
The present invention also adds a certain amount of beeswax, can have a certain amount of inhibitory action to spoilage organisms, and prevents spoilage organisms from entering watermelon inside.
Antistaling agent using method of the present invention is be placed on by antistaling agent in spray bottle, after watermelon cuts; as early as possible antistaling agent is sprayed onto the surface of cutting open a watermelon, watermelon surface forms layer protective layer, is placed in refrigerator by watermelon and preserves; during use next time, carefully by protective layer removal and edible.
Also can antistaling agent be placed in container, the watermelon cut is soaked in container, take out, be placed in refrigerator and preserve.
Fresh-keeping agent of watermelon of the present invention is all extract from natural material substantially, no side effects, the breeding of anti-bacteria, prevents the rotten of watermelon, can keep the freshness of watermelon the long period.
