Invention is selected or the carbon-dioxide absorbent of compounding can actually absorbing carbon dioxide, it is dense effectively to control carbon dioxide in bag
Degree.
Two, moisture changes：
Dehydration situation and carbon-dioxide absorbent, the moisture absorption situation of super water absorbent resin of the mushroom in storage,
It is apparently higher than blank group for the mushroom percentage of water loss of processing group.There is the moisture of 59-71% by titanium dioxide in the moisture that mushroom loses
Absorbent carbon or super water absorbent resin absorb.This explanation remains in the moisture of package interior or is attached to polybag inner surface
Condensed water is less, is conducive to the appearance of polybag and inhibits the growth of microorganism.On the contrary, condensed water is very in blank group polybag
More, many condensed waters drip to mushroom surface again（Make the reduction of its weight-loss ratio to a certain extent）So that its surface is shaded, and is lost
Commodity value.
Three, other quality index change
After being stored 5 days at 10 °C, different disposal group mushroom quality index（Weight-loss ratio, colour brightness, case hardness, smell,
Sense organ acceptance level, total plate count）Comparative situation be shown in Table 1.It can be clearly seen that from table 1, in addition to weight-loss ratio, blank group
Mushroom is below processing group, particularly less than processing group SC and SC/CH in other quality index.The mushroom surface color ratio of blank group
Other groups are deeper darker, and appearance is poor compared with other groups, and there is apparent water logging trace on surface.This illustrates the titanium dioxide made by the present invention
