Problems solved by technology

Some optical technologies are very expensive, require lasers, high-quality optics, and specialized data acquisition equipment, and are still in the laboratory development stage
[0005] Currently, IR thermometers are the most widely used spectroscopic technology for temperature measurement or imaging, but require special infrared optical materials for infrared light transmission and detection, which will increase the manufacturing cost of the instrument

Embodiment Construction

[0035] Reference will now be made to embodiments of the invention, one or more examples of which are illustrated in the figures. The examples are provided by way of illustration of the invention and are not intended as limitations of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. It is intended that the present invention cover these and other modifications and variations as falling within the scope and spirit of the invention.

[0036] figure 1 An apparatus 100 for controlling the temperature of food is illustrated. The device 100 includes a container 102 for receiving food 101 , which may be made of metal, glass or other material with good thermal conductivity. Advantageously, the container 102 can form a closed space during the operation of the device 100, so that the accuracy of food temperature control can be improved.

Abstract

The invention proposes a method of controlling food temperature, the method comprising the steps of: heating food to a first target temperature; exciting a fluorescent marker of the food, wherein the fluorescent marker corresponds to a fluorophore of nutrient substance and / or anti-nutrient substance within the food; detecting current fluorescence- related parameter value of the fluorescence marker, and based on current heating time and predetermined relationships between heating time and fluorescence-related parameter value, calculating current reference fluorescence-related parameter value; comparing the detected current fluorescence-related parameter value with the calculated current reference fluorescence-related parameter value; and controlling heating power supplied to the food based on a comparison result.

Description

technical field [0001] The present invention relates to cooking process control, and in particular to an apparatus and method for controlling the temperature of food during a cooking process. Background technique [0002] Temperature control is an important element that will significantly affect food nutrition and aroma during the cooking process. In the case of vegetable oils, they should be used below their smoke point for health reasons. The smoke point is the temperature at which vegetable oil will begin to smoke and begin to break down. Deep frying vegetable oil will undergo a series of complex chemical reactions, such as oxidation, polymerization, hydrolysis, cis / transisomerization, conjugation, pyrolysis, and cyclization. These reactions are known to affect the organoleptic, nutritional and functional properties of fried foods. Additionally, many degradation products of frying oils are harmful to human health as they destroy vitamins, inhibit enzymes and can potent...
