Abstract
The invention provides preservation balls for fruits and vegetables. The preservation balls comprise the following raw materials in percentage by weight: 40 to 50 percent of nano-titanium dioxide, 4 to 6 percent of negative ion powder, 5 to 10 percent of drilling agent and the balance of carriers. The preservation balls provided by the invention are formed by mixing and grinding the raw materials; processing into balls; and baking at the temperature of between 950 and 1,050 DEG C. The preservation balls provided by the invention have fewer components; the raw materials are easy to obtain; the preparation process is simple; the raw materials can be used repeatedly; therefore, the preservation balls are economic and practical.
Description
Technical field
The present invention relates to a kind of food preserving fruit and vegetable utilizing ball.
Background technology
Vast territory and abundant resources in China, vast in territory, Just because of this, causes distance difference, climate difference etc. between a lot of fruit and vegetables place of production and the land used, adds in storage after fruits and vegetables are gathered, transportation, the sales process, has large-tonnage product putrid and deteriorated unavoidably, causes damage.Therefore, preserving fruit and vegetable utilizing is a problem that urgency is to be solved.
Fruit and vegetable picking causes the reason of fruits and vegetables corruption later on, mostly is because the ethylene gas that the respiration of fruits and vegetables produces and water evaporates loss and microbial proliferation etc.Wherein most important factor is the ethylene gas that produces because of respiration, can make fruits and vegetables yellow, softening, putrid and deteriorated.As seen, reduce the breathing of fruits and vegetables, reducing or eliminating ethylene gas is the main means of antiseptic preservation of fruits and vegetables.At present the antistaling agent that uses mainly is based on the absorbent-type of activated carbon with based on the oxidation Decomposition type two big classes of potassium permanganate.Promptly lost efficacy after but the former active carbon adsorption is saturated; It is slow that the latter but removes gas velocity, and fresh-keeping effect is not obvious.
Chinese patent application 200610012411.8 discloses a kind of nano biological antistaling agent alive, adopts all products of nano materials composition such as nano silicon, nanometer alchlor, nano titanium oxide, nano zine oxide, and the cost height is not suitable for practical application.
Chinese patent application 200610155124.2 is also disclosed kind nanometer fruits and vegetables normal temperature antistaling agent, adopt carrier, nano titanium oxide, Nano Silver titanium, ethyl-para-hydroxybenzoate, to multiple materials such as hydroxyl propyl formate, iron powder, cinnamic aldehyde, activated carbon, divide many group materials, material is respectively organized in preparation earlier, each material mixes again then, and process is many and complicated, disposable use, the cost height, also uneconomical practicality.
Summary of the invention
It is few to the invention provides a kind of constituent, and raw material is easy to get, and preparation technology is simple, reusable, economical and practical fresh-keeping ball.
Fresh-keeping ball provided by the invention, form by following weight percentages: nano titanium oxide 40-50%, negative ion powder 4-6%, perforating agent 5-10%, all the other are carrier.
Fresh-keeping ball provided by the invention, described carrier are the composition of any or two kinds in kaolin, the clay.
Fresh-keeping ball provided by the invention is with the raw material mixed grinding, is processed into ball-type, fires to form under gradient increased temperature 950-1050 ℃ temperature.
Fresh-keeping ball provided by the invention after the use, can take out cleanly, and oven dry or airing can repeated multiple times use again, approximately reusable 20 times.
K2O, Na2O, CaO and the MgO etc. that contain a large amount of AL2O3, SiO2 and a spot of Fe2O3, TiO2 and trace in the kaolinic chemical composition, has the performance of from surrounding medium, adsorbing various ions and impurity, and the more weak ion-exchange character of tool in solution, the perforating agent such as the straw grass meal that add are at high temperature burnt, can form countless apertures at material internal like this, strengthen absorption property more; In addition, the plant ash main component is a potash, and potash is strong base-weak acid salt, hydrolysis takes place in water produce hydroxide ion.
Nano titanium oxide can not only influence bacterial reproduction power, and can destroy the membrane structure of bacterium, reach thorough bacterium for degrading, prevent the secondary pollution that endotoxin causes, nano titanium oxide belongs to non-dissolution type material, and at degradable organic pollutant with when killing bacterium, self does not decompose, not stripping, photocatalysis is lasting, and has lasting sterilization, degradation of contaminant effect.
Therefore, this product provided by the invention is widely used in the fresh-retaining preserving of food such as the melon and fruit, fruit, vegetables, flowers, meat, birds, beasts and eggs, seafood, edible mushroom of any kind at normal temperatures, freshness date is reducible to reach 2-4 month, and original color, matter have effectively been improved, and can remove fruits and vegetables residual toxicity and harmful heavy metal, organic compound and other harmful substances, but also can generate ecological oxygen [O], the hydroxyl radical free radical [OH-] that has ecological catalysis, activates power, and a large amount of negative oxygen ion that discharges.
The specific embodiment
Embodiment 1
Get 360 gram kaolin, 100 gram straw grass meals, grind to form 550 orders respectively, add negative ion powder 40 grams, 500 gram nano titanium oxides mixing that Zibo new material Science and Technology Ltd. of refreshing nation produces again, make the ball of diameter 2-3mm, airing under the normal temperature, under gradient increased temperature 950-1050 ℃ temperature, fired 8 hours, come out of the stove then.
Embodiment 2
Get 300 gram kaolin, 190 gram clays, 50 gram straw grass meals, grind to form 650 orders respectively, add negative ion powder 60 grams, 400 gram nano titanium oxides mixing that Zibo new material Science and Technology Ltd. of refreshing nation produces again, make the ball of diameter 2-3mm, airing under the normal temperature, under gradient increased temperature 1000-1050 ℃ temperature, fired 8 hours, come out of the stove then.
