Harnessing NIR Spectrometry to Measure Fat Content in Line with Vietnamese Nutritional Regulations

This blog post explores the application of NIR spectrometry in measuring the fat content of milk, with a specific focus on complying with nutritional regulations in Vietnam. The significance of accurately determining milk fat content is explained, along with the utilization of NIR spectrometry as a reliable and efficient solution. Additionally, the blog highlights the necessary data and analysis required to meet the regulations established by Vietnamese authorities. By employing advanced technology including the OCEAN-HDX-XR spectrometer, HL-2000-FHSA-LL light source, BIF400-VIS-NIR reflectance probe, STAGE-RTL-T stage, and Ocean View software, dairy producers can achieve precise measurements of milk fat content, enabling them to meet the established nutritional guidelines in Vietnam. This blog aims to provide valuable insights and practical guidance for professionals in the dairy industry, helping them ensure product quality and regulatory compliance while optimizing production processes.

We offer a comprehensive system for measuring fat content using Ocean Insight’s products, including the OCEAN-HDX-XR spectrometer, HL-2000-FHSA-LL light source, BIF400-VIS-NIR reflectance probe, STAGE-RTL-T Reflection and Transmission Stage with Variable Rail, and Ocean View software. Here's how this system can be utilized for fat content measurement:

1.           OCEAN-HDX-XR spectrometer: The OCEAN-HDX-XR is a high-performance spectrometer capable of capturing spectral data over a wide range of wavelengths, including the near-infrared (NIR) region. It provides precise and accurate measurements, making it suitable for determining fat content in milk.

2.           HL-2000-FHSA-LL light source: The HL-2000-FHSA-LL is a broadband light source that emits light across the visible and NIR regions. It ensures a consistent and stable light output, which is essential for reliable measurements.

3.           BIF400-VIS-NIR reflectance probe: The BIF400-VIS-NIR reflectance probe is designed for measuring reflected light from a sample. It offers excellent light collection efficiency and spectral performance in the visible and NIR regions. This probe can be used to collect light reflected from the milk sample during measurement.

4.           STAGE-RTL-T Reflection and Transmission Stage with Variable Rail: The STAGE-RTL-T is a versatile stage that allows for precise positioning and alignment of samples. It enables both reflection and transmission measurements, making it suitable for different fat content analysis techniques.

5.           Ocean View software: Ocean View is a powerful software provided by Ocean Insight for instrument control, data acquisition, and analysis. It offers a user-friendly interface to configure the spectrometer and acquire spectral data. The software also provides various tools for spectral analysis and data processing.

To measure fat content using this system, the following steps can be followed:

1.           Set up the OCEAN-HDX-XR spectrometer and connect it to the Ocean View software.

2.           Prepare the milk sample according to the specific requirements for fat content measurement.

3.           Position the BIF400-VIS-NIR reflectance probe to collect reflected light from the milk sample.

4.           Place the milk sample on the STAGE-RTL-T stage, either for reflection or transmission measurement, depending on the chosen method.

5.           Configure the spectrometer settings in the Ocean View software, such as integration time and wavelength range.

6.           Initiate the spectral acquisition process using the software.

7.           The spectrometer will emit light through the HL-2000-FHSA-LL light source, which will interact with the milk sample. The BIF400-VIS-NIR probe will collect reflected light, capturing spectral data.

8.           The Ocean View software will display the acquired spectrum on the computer screen.

9.           Analyze the NIR spectrum using appropriate chemometric methods or calibration models to determine the fat content in the milk sample.

10.         Repeat the measurement process for multiple milk samples to establish a reliable fat content measurement system.
