A method of extending shelf-life of food is provided herein. The extended shelf-life is provided by treating the food with at least one shelf-life extender selected from a group consisting of an isothiocyanate, a non-aromatic cyclic ketone, a boronic acid and a ligand.

Materials and methods for extending shelf-life of foods

A food with an extended shelf-life and a method of extending shelf-life of food is provided herein. The extended shelf-life is provided by treating the food with isothiocyanate, a non-aromatic cyclic ketone, a boronic acid, a ligand and their precursors.

This application relates to a time-temperature indicator based on increased thermal reactivity of a diacetylene upon melt recrystallization and a method of making it. A diacetylene is crystallized into a low thermal reactivity phase from a solvent system and converted into a higher thermal reactivity phase and low sensitivity to UV light by melt re-crystallization.

A nucleating agent composition, a method of forming the nucleating agent and a device comprising the nucleating agent composition are provided. The nucleating agent comprises a nucleating agent comprises silver halide salt with an average particle size of at least 10 nanometer to no more than 100 microns in a polymeric matrix wherein the polymeric matrix has a viscosity of at least 500 cP to no more than 50,000 cP.

In-situ generation of nucleating agents for indicating devices

This invention relates to thin indicating devices, such as time-temperature indicators and a method of making by applying and UV curing one or more layers of indicating composition are disclosed. For example, an indicator layer is applied on substrate and cured with UV light, immediately followed by an application of an activator layer which is cured by UV light. The device can have other layers, such as a permeable barrier between the activator and indicator layer and a top protective layers which are also UV cured. This fast curing method prevents premature reactions, e.g., diffusion of activator into indicator layer and vice versa during manufacturing.

Compositions, devices and processes related to etching of a very thin layer or fine particles of a metal are disclosed for monitoring a variety of parameters, such as time, temperature, time-temperature, thawing, freezing, microwave, humidity, ionizing radiation, sterilization and chemicals. These devices have capabilities of producing a long and sharp induction period of an irreversible visual change. The devices are composed of an indicator comprising a very thin layer of a metal and an activator, e.g., a reactant, such as water, water vapor, an acid, a base, oxidizing agent or their precursors, which is capable of reacting with the said indicator. Ink formulations composed of a metal powder and a proper activator can be used for monitoring several sterilization processes, such as sterilization with steam. When water is used as an activator, a thin layer of metals, such as that of aluminum can be used as steam sterilization or humidity indicator.

Indicating devices based on etching of metals

This invention relates to indicating devices, such as time-temperature indicators based on lateral diffusion of a vapor of a solid and/or liquid mobile phase (e.g., a sublimeable dye or an activator) through a non-porous stationary phase, such as a thin layer of a polymeric material. The lateral diffusion of the mobile phase creates a noticeable boundary in the stationary phase whose movement depends upon processes, such as time and temperature.

A freeze indicator, which is preferably a self-activating freeze indicator. The freeze indicator has a substrate with a freeze indicator composition coated thereon wherein the freeze indicator has a liquid diacetylene; and a catalyst or catalyst precursor and a protective cover.

Freeze, thaw and refreeze indicators based on rapid reactions in the solid state

Monitoring system based on etching of metals

Disclosed is a device for monitoring one or more of integral value of time and temperature, UV light exposure and a pre-determined temperature of an item. The device is useful for monitoring items or materials which are sensitive to time-temperature, UV light and/or a pre-determined temperature. Radiation sensitive devices such as self-indicating instant radiation alert dosimeters (SIRAD) can be accidentally, inadvertently or intentionally over exposed to time-temperature, UV light and a pre-determined higher temperature. Such over exposure can provide a false positive or false negative signal. A device based on polymerization of diacetylenes and melting of partially polymerized diacetylenes, both of which are associated with color changes, are proposed as false positive, false negative, and tamper indicator.

Time-temperature, UV exposure and temperature indicator

A radiation detection device with at least one self indicating radiation sensor and at least one machine readable sensor.

Device and a process for mass monitoring of radiation exposure

Described is a self-indicating instant radiation dosimeter () for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition (), e.g., a diacetylene (R&#x2014;C&#x2261;C&#x2014;C&#x2261;C&#x2014;R', where R and R&#x2032; are substituents groups) or a radiochromic dye, a polymeric binder () and optionally a shelf life extender () or an activator (). The radiation sensitive composition () changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition () is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.
