Embodiment

[0017] Embodiment: the quantification method of the calculation and analysis food energy of this example, its steps are: as figure 1 , e1: the required energy intake value per time unit; e2: food energy value; t: the length of time that the nutrients contained in the food can supply human energy, or the nutrients contained in the food to be selected for a certain period of time in the future The length of time that energy can be provided to the human body; p: the market price or cost of the food; v: the energy price of the food, which is the price that consumers pay to purchase the food in order to obtain the human body energy required per unit time.

[0018] a. According to the Chinese Residents Dietary Nutrient Reference Intake Table, the energy requirement of a male light worker between the ages of 18 and 49 is 9414 kJ, and the e 1 =9414 / 24=392.25 (kJ / h);

[0019] b. Extract the data of the nutritional content of specific foods, and obtain the following data from the pa...

Abstract

The present invention relates to a method of food analysis, and more particularly to a quantification method for calculating and analyzing food energy. The invention aims to solve the technical problems that the calculation method in the prior art cannot be used as an important quantification basis before the decision making of purchasing the food, and cannot calculate the accurate quantity of theordered dishes, the food waste is large. According to the invention, according to the daily dietary nutrient reference intake table issued by nutrition institutes in different countries and regions,the needed intake value of per time unit is calculated, the food nutritional ingredient data can be obtained when the food is purchased by an intelligent device, e2 / e1=t is calculated, the market price or cost of the above food is extracted and represented by p, p / t=v is calculated, v refers to the energy price of the food and is the price consumed by the consumer for buying the food to acquire the human body energy needed per time unit.

Description

technical field [0001] The invention relates to a food analysis method, in particular to a quantification method for calculating and analyzing food energy. Background technique [0002] The energy of food refers to the energy produced by the metabolism of nutrients such as protein, fat and carbohydrates in food. A Chinese patent discloses a healthy eating behavior prompting method, device and computing system (publication number: CN102955890A), a healthy eating behavior prompting method, its features and the method include the following steps: according to the parameters set by the system, obtain the diet terminal The eating behavior data generated by the user during the eating process: evaluate and calculate the acquired eating behavior data according to the algorithm set by the system; prompt the calculated result to the eating end user. After the step of acquiring the eating behavior data generated by the eating end user during the eating process according to the paramet...
