Thermo-Sensitive Materials for the Time-Temperature Indicator
[Purpose] To show storage-resistant food internal quality changes such as canned food. [Method] By measuring the time-temperature-gray relational model of thermo-sensitive paper, compare it with the time-temperature-quality movement model of storage-resistant food. [Results] The analysis of the example show that: through controlling the production process and prescription of thermo-sensitive paper, adjusting the dosage of color-producing reagent, enabling the variation rule of gray match with the quality change of storage-resistant food. [Conclusions] Based colorless dyestuff 2-phenyl-3-methyl-6, 6-2 D-amino fluoran and 2, 2-bis (4-hydroxyphenyl) propane color developer thermo-sensitive system, through controlling the production process and prescription of thermo-sensitive paper to show the quality change of storage-resistant food.
