Description
Technical field
The preparation method for baking paper with good grease resistance that the present invention relates to a kind of, belongs to baking technical field.
Background technique
It bakes, also known as toasts, bakes, refer to makes material dewatering be hardened under material burning point by xeothermic mode
Process.Baking is that bread, cake-like product make indispensable step, passes through starch after baking and generates gelatinization, protein
After a series of chemical changes such as denaturation, bread, cake achieve the purpose that curing, also the mouthfeel of food can be made to change, and people
Be that food to be processed is placed in pallet to be placed into oven to carry out baking process in practical baking process.
The food that household, which will bake, and the industrial long-standing problem baked in industry is related to bake (or heating) is roasting from it
The ability removed in disk.The solution for centuries of these problems more particularly to butter, lard, vegetable oil or its
His oleaginous material is to disk fat liquoring, sometimes then containing applying flour on oil coating surface.These methods are widely used, but are only
It is partially effective.Moreover, these methods are for numerous food, for example, candy, caramel apple etc. is invalid.
At industrial scale, previously described method is more improper, because of sizable hand labour and preparation baking tray
Correlation, and disk thoroughly must be washed and be dried before the next use.
Disk coated with fluoropolymer such as, or the availability of disk coated with silicone or being even made of completely silicone is
Become useful, especially in household baking.However, these products due to its higher cost and reuse and by
The tendency of surface damage is frequently not suitable for for commercial operation.In addition, such as the disk for being coated with oleaginous material, it usually needs thorough
Bottom cleaning.
In order to avoid these problems, or in order to minimize the clean amount that must be carried out, baking paper is used.It provides
The baking paper of several variants.For example, parchment has been used to this purpose, but usually requires fat liquoring and spread flour.Parchment although
Usually will not be sticky to disk, even but fat liquoring and spread flour, still can be stiffly sticky to some foods.Its use
It can be related to a large amount of hand labour.
Paraffin paper can use many decades, but effectively but invalid to other bakeries to some bakeries.Especially pair
In the food with quite big fat content, fatty material can partly dissolving wax and be adhered firmly on paper.Paraffin paper is not
It can be used for high temperature application.
The baking paper of silicone coated can also be used, but as paraffin paper, is not suitable for some bakeries.For example,
This coating has undesirable rouge and oily tolerance.These coatings are also expensive.
It is the paper coated with the preparation containing chromium stearate that industrial standard, which bakes paper,.One example is coating parchment.Together
Sample, this coating are not suitable for all bakeries.Specifically, these coatings have lower resistance to as silicone coating
It is oil.In addition, the use of chromium compound will receive close scrutiny.For example, the paper of chromium stearate coating cannot be used for wet batter
Using.
Paper is baked it can be seen from previous discussion must show satisfactory property on various bakeries
Can, and the relevant influence of possible health not only must be taken into consideration in the selection of suitable coating, it is necessary to temperature involved in considering
Degree.In latter aspect, in the context of the present invention, " baking " and " baking " is suitable for being formed to be connect at elevated temperatures
Touching bakes the operation of the food of paper.For example, this may include being placed in the candy etc. of heating to bake on paper and do not have in hot oven
There are any real time or more conventional baking to operate, such as bread, muffin, flapjack, biscuit, cake, souffle, pie etc.
Baking.It is thus impossible to based on room temperature or close to the similar formulations of ambient operation use and assess the applicability of coating agent.Example
Such as, the paper of silicone coated, the paper and paraffin paper of chromium stearate coating are usually good with the performance of various food at room temperature, but are increasing
At a temperature of can be by defect at least some food.It is uncertain as the performance for baking paper.
The factor for the problem of various food and its ingredient are all the paper and coatings properly baked.For example, many foods
It containing proteinous material such as whey, casein, albumin and seitan, and is at least partly denaturalized, is formed viscous in baking process
The gel of property.Sugar often caramelization in baking process, condenses into very viscous substance.Other compositions may include oiliness
Substance such as butter, lard or vegetable oil.Some foods such as fruit pie may contain acidic materials (tartaric acid), and other foods are such as
Cracknel, Corn bread and cake may be alkalinity due to using inorganic leavening agent such as sodium bicarbonate.
Bread, cake or other food are in baking process since it is desired that a series of chemical change occurs, in order to hold
It is easily molded, prevent oil or fillings spill, mutual food materials avoided mutually to bind, usually increasing below these food materials has
Paper is baked, is easier to form and Adhesion phenomenon will not occur between each other to reach, and can be to avoid liquid in baking process
The outflow of body, but baking paper in the prior art can usually be dialled at this time after the completion of baking there is a phenomenon where bonding with food
It holds and bakes paper and can relatively bother, and often remain some food above on the baking paper after pushing aside, lead to food
Face be mutually changed, influence the aesthetics of food, in the prior art as Patent No. " CN202450380U " Chinese patent,
A kind of anti-sticking antiseepage painting silicon paper of food-grade high temperature resistant is described, is coated on the two sides of food parchment and applies silicon layer, in this way may be used
To achieve the effect that anti-sticking antiseepage, but it will simply apply silicon layer and be coated on parchment during processing, and apply silicon layer and sheep
The associativity of mulberry paper is bad and easy to be uneven, and it is not highly desirable for leading to anti-sticking anti-seepage effect, and in process of manufacture
Middle baking paper frequent occurrence alice the phenomenon that, the wasting of resources low so as to cause yield rate, exist for provide in human consumption side
The use in face is acceptable, and is economical in production, and various bakeries are effectively coated with the long-term need for baking paper
It wants.

The ability of taste and fragrance can delay the generation of Food Oxidation denaturalization phenomenon, prolong significantly using the gas barrier property of polyvinylidene chloride
Long products shelf life, while the fragrance that can be avoided content scatters and disappears and prevents the intrusion of external bad smell；It is wet using its resistance
Property, capable of preventing product, there is a phenomenon where dehydration exsiccation, taste bad, will not damage packaging prototype because product absorbs water, and prevent
Natural wastage (weightlessness) occurs for quantitative product, and gas barrier properties do not change with the variation of humidity, will not draw high humidity environment
It is rotten to play product；Using its low-permeability, loss of aroma can be prevented, and does not absorb remaining smell and off-taste, it can be with
Guarantee the integrality of smell；It has excellent weather resistance, even if being chronically exposed to outdoor, directly exposes to sunlight, will not fade
And aging phenomenon；
(3) in the present invention based on organic siliconresin resin, prepare a kind of oil-proof paint, organic siliconresin has excellent
The characteristics such as thermo oxidative stability, electrical insulation capability, weatherability, waterproof, salt spray proof, mould proof, biocompatibility, in 250 DEG C of items
After heating 24 hours under part, organosilicon weightlessness is only 2%~8%；The oil-proof paint of preparation has good fissility, and has good
The features such as heat-resisting quantity well, lower temperature resistance and preferable hydrophobicity, so that the baking paper of preparation has good heat-resisting quantity
And fissility.
