As upper table as can be seen that colloid obtained by embodiment 1-4, colloid light transmittance is good, high and low temperature resistance is stablized, and uses
Number of days is grown.And the jelly force value 80 of 1 edible gelatin of comparative example, gel strength are too low, resulting solution is caused to solidify.Comparative example 2-
The number-average molecular weight of 3 acceptance of the bid pseudotype isobutyiene-maieic anhydride alternate copolymers is different, and the performance of its polymer is also different, this leads
Cause the high temperature performance for forming colloid also different, result in the high temperature performance, light transmittance and performance and this hair of colloid
It is bright compared to poor.The PVA degree of polymerization 500 in comparative example 4, its solution formed, relatively low viscosity is only 5, and the adhesion effect of mucus is not
Good, block gel is each other without obvious flow effect.Handled in comparative example 5 without mucus, though gained gel possesses necessarily
Translucency and room temperature use number of days, but for the present invention, light transmittance and be remarkably decreased using number of days, and gel
The defects of seeping water when 60 ° of high-temperature stabilities are tested, gel is poor in -20 ° of low-temperature stabilities, illustrates mucus in the present invention
Processing, not only contributes to the effect for having adhesion to flow between small-sized block gel, for improving light transmittance, using number of days and height
Cryogenic property is favourable.
In order to which further instruction addition mucus is in gel surface, the improvement of performance is used for, was tested using following
Journey come simulate due to collision etc. caused by influence：
50g-80g aromatic of the present invention will be added in 100ML beakers, one 100ML beakers of another preparation add to absorb water on the market
Pearl product aromatic, beaker is shifted onto on the table, beaker mouth is contacted with desktop, and aromatic is simulated using process with this
In, phenomenon that institute's Sheng container is overturned by external force, observed small-sized aromatic in two beakers, the remaining quantity of polymer mix in one minute
Or the aromatic being scattered on the table, polymer mix quantity simultaneously contrast.
The small-sized aromatic of the present invention, because gel surface has mucus, sticks to each other, even if container overturns, is scattered in outer
Controllable quantity, it is less.And the aromatic appearance of polymer mix etc does not have an adhesion, container overturns, and it is then more to be scattered in outer quantity,
It is uncontrollable.
It can be seen from the above that the present invention freezes the standard of the edible gelatin and certain range of number-average molecular weight of force value by a certain range
The crosslinking of type isobutylene maleic acid anhydride alternate copolymer prepares small-sized block gel, is prepared by certain degree of polymerization polyvinyl alcohol viscous
Liquid treatment gel prepares aromatic, and products obtained therefrom transparency is high, and high and low temperature resistance is stablized, and can take on demand, fragrant
While give people to bring pleasing visual perception；And by spraying mucus in block gel surface so that small-sized bulk
The effect for having adhesion to flow between gel, avoids during use because jolting or colliding and be scattered.
