Embodiment Construction
[0025] In order to better understand the present invention, the present invention will be further described below in conjunction with the examples and accompanying drawings, and the following examples are only to illustrate the present invention rather than limit it.
[0026] Such as figure 1 As shown, a method for quickly distinguishing reconstituted and non-reconstituted dairy products using portable near-infrared spectroscopy includes the following steps:
[0027] Step 1 Modeling sample preparation
[0028] (1) Obtain reconstituted and non-reconstituted dairy products: Purchase reconstituted and non-reconstituted dairy products of well-known brands with high reliability in large supermarkets, and carefully check the production date, formula and processing method to ensure the reliability and consistency of the sample source. Remove 10 mL from each dairy product and place in beakers labeled reconstituted and non-reconstituted for later use.
[0029] (2) Sample pretreatment...

The invention relates to the technical field of quick food detection and particularly provides a method for quickly distinguishing reconstituted and non-reconstituted milk products by adopting a portable near infrared spectrum technology. The method comprises the following steps that 1, representative reconstituted and non-reconstituted milk product samples are collected and are preprocessed; 2, near infrared spectrum parameters are optimized, and best spectrum collection conditions are selected as parameter collection conditions; 3, a near-infrared spectrograph is utilized to collect spectrumdata of the reconstituted and non-reconstituted milk products, and clustering analysis and modeling are performed; 4, the samples to be detected are substituted into established detection models forrestoration judgement. The invention relates to the portable near infrared spectrum technology, qualitative analysis is conducted on reconstituted and non-reconstituted milk in unknown samples in virtue of a clustering analysis method in mode recognition, and accurate, quick and reliable detection results are provided for merchants and consumers.
Description
technical field [0001] The invention relates to the technical field of rapid detection of reconstituted dairy products and non-reconstituted dairy products, in particular to a method for rapidly detecting and distinguishing reconstituted milk and non-reconstituted milk based on a portable near-infrared spectrometer combined with principal component analysis. Background technique [0002] Reconstituted dairy products are made by drying fresh milk at high or low temperature into milk powder, then mixing it with an appropriate amount of water to make reconstituted milk, and finally preparing corresponding reconstituted dairy products through appropriate processes. Reconstituted milk raw material milk powder mainly comes from foreign markets such as New Zealand and Australia, and the price of reconstituted milk and dairy products prepared from milk powder is obviously cheaper than fresh milk in the domestic market. Therefore, driven by economic interests, some dairy companies us...
