Embodiment

[0036] The invention is suitable for content determination of various fruit juice preservatives such as benzoic acid, potassium sorbate, sodium lactate and sodium dehydroacetate. In this experiment, benzoic acid was used as the detection sample, and the intelligent taste detection system was used as the detection tool to realize the rapid quantitative detection of the content of benzoic acid in fruit juice.

[0037] The invention mainly relates to sample preprocessing and electronic tongue data processing and modeling methods. An electronic tongue based on an array of interaction-sensitive chemoselective area-effect taste sensors is used. The sensor consists of seven sensors and one Ag / AgCl reference electrode. The names and properties of each sensor are shown in Table 1.

Abstract

The invention discloses a method for predicting the content of benzoic acid in fruit juice based on taste fingerprint information. The method utilizes an electronic tongue system of a chemical field effect sensor and a random forest algorithm to mine the information of the content of benzoic acid in fruit juice at room temperature. Contact the electronic tongue sensor array with the juice containing benzoic acid to generate taste fingerprint information, extract characteristic data from the taste fingerprint information, and conduct qualitative and quantitative analysis of the juice samples by principal component analysis and random forest modeling. The invention adopts the electronic tongue of the chemical field effect sensor array to evaluate the benzoic acid in the fruit juice, provides objective, accurate and quantified information, the index is simple and easy to understand, and the operation is simple, fast and accurate.

Description

technical field [0001] The invention belongs to the technical field of food juice additive detection and relates to a method for rapidly detecting the content of benzoic acid in fruit juice by using taste fingerprint information. Background technique [0002] With the continuous development of fruit juice beverage industry, various food additives are widely used in fruit juice beverages. Food additives play a decisive role in the preservation and stability of fruit juice, but the safety of additives has attracted widespread attention. All countries have formulated relevant laws and regulations to limit the use of food additives. [0003] Benzoic acid, also known as benzoic acid (C6H5COOH), has a good antiseptic effect, a wide range of antibacterial under acidic conditions, good antiseptic effect and low price, so it is widely used as a preservative in beverages, sparkling wine and daily condiments . my country's food hygiene standards stipulate that the maximum amount of ...
