Abstract
The invention discloses a fresh-keeping agent which comprises the following components in parts by weight: 0.6-5 parts of chitosan, 0.05-0.5 part of ethylene diamine tetraacetic acid, 0.3-5 parts of vitamin C, 0.2-5 parts of sodium benzoate and 1000 parts of distilled water. The invention further discloses application of the fresh-keeping agent. A toothpick preserved by the fresh-keeping agent prepared by the invention does not easily fade and discolor, and the hardness of the toothpick is kept well; a toothpick made of a herbaceous stem rod has a certain flexibility, is better than common bamboo toothpicks, wooden toothpicks, plastic toothpicks and stainless steel toothpicks, and does not easily puncture gingiva, the inner wall of the oral cavity, and the like, and thus a wound is difficultly formed to avoid infection. 1-30 toothpicks preserved by the fresh-keeping agent prepared by the invention can be packaged together with the fresh-keeping agent in each bag; the fresh-keeping agent has a certain corrosion preventing function when keeping fresh, is opened when being used, and can be directly selected without using hands, thus the secondary pollution of the fresh-keeping agent during use is alleviated, and the damage to the oral cavity and the gingiva when the toothpick is used is alleviated.
Description
Technical field
The invention of this reality belongs to daily living article quality maintenance technology field, particularly a kind of fresh-keeping liquid and application thereof.
Background technology
Toothpick is the particularly more Tooth pickses of the elderly's use of people, at present, and thick, the fusiform wooden or bamboo matter body of rod in the middle of conventional toothpick mostly is, or the plastic toothpick that one end is sharp-pointed, centre is thicker, is difficult for running through teeth space, sometimes rejects and does not fall to be embedded in the thing in teeth space; Material is also all harder, is easy to poke gum and oral cavity wall.And bamboo, that wooden toothpick has is jagged, is also easy to scratch oral cavity, equally causes bleeding incessantly with poking, and forms wound.If toothpick sterilization is not exclusively, can intrinsic energy numerous bacterium and virus, these bacteriums, virus are easy to enter blood circulation system by wound, cause blood-borne diseases, as hepatitis B, the third liver, AIDS etc.; Or cause and oral cavity common bacteria such as infecting some streptococcus cause heart disease and meningitis etc.
Chinese Consumers' Association issues warning of consumption and says, mostly bamboo, the wooden toothpick that domestic restaurant is equipped with is " three nothings " product, and country is not yet toothpick formulation relevant criterion, and therefore, consumer should prop up at every turn and choose a toothpick, can only, with once, prevent secondary pollution.But most disposable toothpick sterilizations not exclusively, is generally placed in toothpick holder, likely by quite a few people, with picking, taken, so the not safety and sanitation in fact of disposable toothpick.
The toothpick thickness that people use is at present all the same, when picking one's teeth seam, sometimes dislikes thick, can not pass through teeth space gap; Sometimes dislike thin, thickness cannot regulate, select.After generally bamboo, wooden, plastics toothpick is used, do not use vestige, reuse and do not see, likely cause microbial contamination.
Bamboo, wooden toothpick is also wasted bamboo and timber resources.The toothpick that the macromolecular materials such as plastics are made is usually with a bit of dental floss, and dental floss China resident uses uncomfortable; The toothpick of plastic tip is larger with the same hardness of wooden, bamboo toothpick, also has the hidden danger of poking oral cavity.And, plastic products, degraded difficulty, can cause environmental pollution.Generally bamboo, wooden, plastics toothpick is compared, and fresh plant cane has hardness also to have toughness as toothpick, is difficult for again damage oral cavity and gum when removing teeth space; Reuse and can find out that quality becomes crude, the possibility of microbial contamination is very little; And herbaceous stem toothpick, fast growth, biogenetic derivation is abundant, economizes on resources, and decomposes soon non-environmental-pollution.
Herbaceous stem toothpick is not save-resistant, can lose moisture after long time stored, and suppleness cannot maintain, and only has and keeps the freshness of plant just can maintain suppleness, maintains toothpick and better uses function.
Summary of the invention
Goal of the invention: the problem and shortage existing for above-mentioned existing scheme, in order to keep the distinctive suppleness of plant, and for fresh-keeping, maintain the normal usage function of toothpick, and preventing that microbial contamination from appearring in toothpick storage process, first object of the present invention has been to provide a kind of fresh-keeping liquid.Second object of the present invention has been to provide the purposes of above-mentioned fresh-keeping liquid.
Technical scheme: for achieving the above object, technical scheme of the present invention is as follows: a kind of fresh-keeping liquid, consists of the following composition by weight: 0.6～5 part of shitosan, 0.05～0.5 part of disodium ethylene diamine tetraacetate, 0.3～5 part of vitamin C, 0.2～5 part of Sodium Benzoate, 1000 parts of distilled water.
Preferably, consist of the following composition by weight: 1.2～3.6 parts of shitosans, 0.10～0.3 part of disodium ethylene diamine tetraacetate, 0.6～1.8 part of vitamin C, 0.4～1.2 part of Sodium Benzoate, 1000 parts of distilled water.
More preferably, consist of the following composition by weight: 3 parts of shitosans, 0.3 part of disodium ethylene diamine tetraacetate, 1.5 parts of vitamin Cs, 2.5 parts of Sodium Benzoates, 1000 parts of distilled water.
The application of above-mentioned fresh-keeping liquid aspect preparation plant toothpick.
A novel plant toothpick, described toothpick contains above-mentioned fresh-keeping liquid.
A preparation method for novel plant toothpick, comprises the following steps:
1) choose the unifacial leaf gramineae plant cane of the stem of 0.05-0.5 cm diameter, cut into the toothpick body of a plurality of 3-9 centimeter length;
2) toothpick body has been placed in 55-85 ℃ add to the distilled water pasteurization 5-30 minute of bactericide;
3) again by step 2) the toothpick body that obtains immerses in described fresh-keeping liquid and splitting sealing obtains being equipped with toothpick packaging bag;
4) by packaging bag again sterilizing get product.
Wherein, above-mentioned unifacial leaf gramineae plant is annual bluegrass, cogongrass or herba setariae viridis grass etc.
Wherein, above-mentioned bactericide is liquor natrii hypochloritis, geramine or bromogeramine etc.
Can select packing according to use habit, open several with several, also can use according to teeth space size is folding, once be finished, with toothpick use side later, become crude, quality changes, folding with have a folding line.
Beneficial effect: compared with prior art, fresh-keeping not fugitive color, the variable color of toothpick of fresh-keeping liquid prepared by the present invention, the pliability of toothpick keeps better, more bamboo, wooden, plastics, stainless steel toothpick are good, be difficult for poking gum, oral cavity wall etc., be therefore difficult for forming wound and cause infection.The fresh-keeping toothpick of fresh-keeping liquid prepared by the present invention can be according to using needs to be only packaged into every bag of 1-30 together with fresh-keeping liquid, fresh-keeping have certain anti-corrosion function simultaneously, do not need directly to choose with hand, reduce the secondary pollution while using, reduce the damage to oral cavity, gum when toothpick is young to be used.Plant toothpick prepared by the present invention simple in structure, is easy to manufacture, with low cost; Convenient and healthy, thickness is adjustable, is easy to use; Hardness toughness is suitable, not easy damaged user; Source is abundant, economizes on resources, free from environmental pollution.
