Description
Technical field
The invention belongs to desiccant technical field, be specifically related to the preparation method of a kind of Pericarpium Musae desiccant and the dry mildew-resistant bag containing Pericarpium Musae desiccant.
Background technology
Present desiccant kind is a lot, such as: Quick lime desiccant, calcium chloride desiccant, silica-gel desiccant etc..Quick lime desiccant, calcium chloride desiccant, silica-gel desiccant are widely used because its drying effect is good, cheap, but have occurred that the blast of many causes above-mentioned desiccant causes the event of consumer's eye injury in recent years, it is also of common occurrence that consumer eats the thing of desiccant by mistake, and this has caused the extensive concern of people；And existing desiccant there is also or use chemical composition, having certain toxicity, outer package is once revealed and is easily polluted materials such as needing the food that preserves, or the weak point that preparation method is complicated.Based on this, the desiccant developing a kind of new type extremely has meaning.Desiccant is typically all to be packed with ventilative paper material, can pollute food in packaging bag in the case of having damaged leakage.
The natural component utilizing plant goes to prepare desiccant because of safety and sanitation, more environmentally-friendly and paid close attention to widely, if but the plant component after directly using undressed process goes as desiccant, drying effect is limited, wettability power is more weak, can not ensure that food waits that preserve material is stored in dry environment in shelf life always well, and then easily make the materials such as food mouldy during shelf, corrupt, the most how natural plant composition is processed so that it is there is higher wettability power there is researching value very much.
Summary of the invention
For deficiencies of the prior art, the technical problem to be solved in the present invention is: has that easily blast, security performance be low for desiccant in prior art, limited wettability, easily cause the technical problem eating danger by mistake, and provides the preparation method of the excellent Pericarpium Musae natural seasoning agent of a kind of natural safety, moisture sorption effect and the dry mildew-resistant bag containing Pericarpium Musae desiccant.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that the preparation method of a kind of Pericarpium Musae desiccant, comprises the steps:
1) Pericarpium Musae cleaning, cutting are taken；
2) ethanol and acetic acid are configured to Ethanol-Acetic Acid mixed solution according to the volume ratio of 4 ~ 6:1, the Pericarpium Musae after step 1) cutting is immersed activation processing 3 ~ 7 h in described Ethanol-Acetic Acid mixed solution；Wherein, described Pericarpium Musae is 400 ~ 600 g/L with the mass volume ratio of Ethanol-Acetic Acid mixed solution；
3) to step 2) after Pericarpium Musae after activation processing freezes 2 ~ 4 h at-60 ~-40 DEG C, lyophilizing 8 ~ 10 h under freeze temperature-20 ~-30 DEG C, vacuum 40 ~ 65 Pa；
4) Pericarpium Musae dried to step 3) carries out broken and sieves, and chooses 20 ~ 40 mesh sieve siftage, obtains described Pericarpium Musae desiccant.
A kind of dry mildew-resistant bag, including the dry mildew-resistant bag inclusion made with gas permeable material, is filled with the Pericarpium Musae desiccant using said method to prepare in described inclusion.
Compared to existing technology, there is advantages that
1, the present invention passes through acetic acid and alcohol mixed solution as activator, Pericarpium Musae is immersed in activator, can make during in Pericarpium Musae, partial organic substances is dissolved in activator, Organic substance leaves hole after being dissolved in Pericarpium Musae, in Pericarpium Musae after activation, structural void increases, overall specific surface area increases, the functional group can reacted with water generation chemical bonding in Pericarpium Musae is made to come out more, and then enable the Pericarpium Musae after activation to contact with hydrone more, for the more preferable condition of dry offer.
2, when Pericarpium Musae desiccant water absorption rate of the present invention is up to 38%(relative humidity RH=40%), and the desiccant water absorption rates such as existing silica gel are only 20%(HG/T2765-2005, during RH=40% >=20%), visible Pericarpium Musae desiccant water absorption rate of the present invention reaches 1.8 times of existing desiccant, achieves beyond thought technique effect.
3, the Pericarpium Musae desiccant that the present invention prepares is yellow, before water suction and after water suction, color changes significantly, i.e. become block from powder, color from yellow becomes light/dark balance, consumer can be facilitated to judge, and Pericarpium Musae desiccant has absorbed water, it is easy to the Pericarpium Musae desiccant more renewed in time, it is ensured that drying effect.
4, Pericarpium Musae desiccant of the present invention is entirely by pure natural plant fiber, does not has any injury to human body, also human body will not be produced any impact even if wrongly taking, and itself have faint scent, be particularly suitable for the dry use of luxury food and baby food etc..
5, Pericarpium Musae stock number is huge; Pericarpium Musae is typically thrown away after having eaten Fructus Musae by people; not only waste resource but also pollute environment; the present invention is by making desiccant by Pericarpium Musae; not only increase the added value of banana industry; peasant increases production and improves productivity, and also protects environment, makes food safety be guaranteed.
