Embodiment 1

[0033] Various nutrients in the food, such as sugar, protein, water, fat, etc., have different absorption characteristics to infrared rays, and different nutrients will have strong absorption characteristics for a certain specific band of infrared rays. This embodiment uses this According to a principle, in this embodiment, this specific wave band is called the matching wave band of the nutrient composition. Fig. 1 is a schematic diagram showing the corresponding relationship between various nutritional components and their infrared absorption characteristics in matching bands. Taking nutritional ingredient 1 as an example, the infrared absorption amount of nutritional ingredient 1 per unit mass (such as 1KG) to matching band 1 is A. The data in this table can be obtained by actual measurement.

[0034] The mobile terminal of the present embodiment pre-stores such a table as Fig. 1, therefore, if it is possible to measure the absorption of various nutritional components in th...

Embodiment 2

[0049] The idea of ​​this embodiment is to measure the content of various nutritional components in the food by utilizing the difference in the infrared band and energy radiated by different substances. In this embodiment, the infrared bands radiated by different substances are referred to as radiation bands.

[0050] Fig. 5 is a diagram showing the correspondence relationship between various nutritional components and the radiated energy in the radiation band. Taking nutrient component 1 as an example, the infrared radiation amount of nutrient component 1 in its radiation band 1 per unit mass (such as 1KG) is A'. The data in this table can be obtained by actual measurement.

[0051] The mobile phone terminal of the present embodiment prestores the table like Fig. 5 in advance, therefore, if can measure the radiation amount of various nutritional ingredients in the food respectively in its radiation band infrared radiation, then with the various nutrition prestored in the tab...

Abstract

This invention provides one food nutriment component analysis method and device based on mobile communication terminal, which comprises the following steps: mobile communication terminal sends invisible light to food and receives food feedback invisible light; the said mobile communication terminal analyzes the nutriment component content according to invisible light and energy difference and then generates nutriment component analysis result; the said terminal output the analysis result of nutriment component.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a mobile communication terminal-based food nutritional component analysis method and device thereof. Background technique [0002] The fast-paced lifestyle, fast food culture and high-calorie diet in modern society have led to the spread of many "diseases of affluence" and kept the number of obese people high, which not only poses a threat to people's health, but also does not conform to the current "thinness". for beauty" aesthetics. If you can improve your diet, establish reasonable eating habits, and replace high-calorie foods with a balanced and reasonable diet, you will get more nutrients and stay away from obesity and obesity-related diseases. Let our body be healthier. If the content of nutritional components of food can be measured before meals, it will be convenient for diners to choose food types. [0003] Since different substances can radiate infrared ra...
