Control and inspection operations within the context of safety and quality assessment of bulk foods and feeds are not only of particular importance, they are also demanding challenges, given the complexity of food/feed production systems and the variability of product properties. Existing methodologies have a variety of limitations, such as high costs of implementation per sample or shortcomings in early detection of potential threats for human/animal health or quality deviations. Therefore, new proposals are required for the analysis of raw materials in situ in a more efficient and cost-effective manner. For this purpose, a pilot laboratory study was performed on a set of bulk lots of animal by-product protein meals to introduce and test an approach based on near-infrared (NIR) spectroscopy and geostatistical analysis. Spectral data, provided by a fiber optic probe connected to a Fourier transform (FT) NIR spectrometer, were used to predict moisture and crude protein content at each sampling point. Variographic analysis was carried out for spatial structure characterization, while ordinary Kriging achieved continuous maps for those parameters. The results indicated that the methodology could be a first approximation to an approach that, properly complemented with the Theory of Sampling and supported by experimental validation in real-life conditions, would enhance efficiency and the decision-making process regarding safety and adulteration issues.

“…However, the traditional methods for the quantitative determination of mycotoxins in food and feed (mass spectrometric (MS), high-performance liquid chromatographic (HPLC) based on UV or MS detection) have some typical drawbacks, such as high costs of implementation, long time of analysis, low samples throughput, and need for highly qualified operator. Therefore, the availability of fast, reliable and simple methods to use as detecting tools for evaluating food and feed contaminants is one of the main challenges for a modern food and feed industry, in order to safeguard customer's health and improve production safety (Cheli et al, 2012). In recent years, several cost-effective and suitable approaches have been proposed to assess the effectiveness of safety measures and to achieve logistical and operational goals.…”

“…The application of analytical techniques, such as infrared spectroscopy (NIR, FR-NIR) and electronic nose, coupled with chemometric tools, is a rapid, non-invasive and promising analytical approach for mycotoxin analysis. Advantages and drawbacks of these technologies are reported in Table 3 ( Cheli et al, 2012). The development and implementation of fast, non-destructive, and applicable methods in a screening control procedure for the evaluation of the content of undesirable substances in food and feed must take into consideration the maximum levels or guidance values established by the EU.…”

Chemical hazards may occur in any phases of the different livestock production systems. Aim of this review is to address an update about the key issues related to the risk of contamination in foods of animal origin by environmental contaminants linked to industrialisation or urbanisation (e.g., heavy metals and persistent organic pollutants), and natural contaminants (e.g., mycotoxins). This review deals with current issues and future perspectives on the complex issue of the safety of feeds and foods of animal origin, by taking into account the estimation of the occurrence of chemical residues in food, the hazard identification and characterisation of mycotoxins in animal feeds, and the analysis of feedstuffs as a tool to control and evaluate food safety.

“…Therefore, the implementation of alternative methodologies and procedures addressing the existing constraints of traditional sampling and analysis techniques is imperative. 4 The availability of advanced technologies to implement on-site analysis is already a reality. In this regard, near infrared (NIR) spectroscopy has become an important source of improvement, contributing to the use of faster, simpler to use and more reliable detecting tools and, hence, to the implementation of more efficient and modern monitoring and control systems.…”

Feed grains are typically transported in bulk and a statistically representative sample of the grain in the truckload is usually required to be taken to the laboratory for wet chemistry or at-line near infrared (NIR) spectroscopy analysis. Currently, most methodologies make use of a physical sampling probe, which mechanically or pneumatically withdraws samples from various depths. Nevertheless, not only is the implementation of this approach expensive and time-consuming, but it is also limited by low sample throughput. In this context, the authors' group is involved in a large research and development project to find more efficient and cost-effective ways of sampling and analyzing bulk raw materials at the reception level. This work presents a piece of this research focused on the evaluation of the optical performance of two fiber-optic probes designed for automated use as immersion probes in truckloads. It is worth noting the rather different optical design of these two diffuse reflectance probes. Probe A features eight bundles (37 fibers/bundle), four for measurement and four for illumination, 0.5 m in length, and four sapphire windows located around the probe diameter. Probe B has one fiber-optic bundle for measurement (7 fibers) and one for illumination (19 fibers), 3 m in length, and a stainless-steel head with two sapphire windows. The experimental design of this laboratory study aimed at imitating the control of bulk lots of two sort of cereals (maize and wheat). For this purpose, a sample of each cereal was placed into a container (0.34 m in width, 0.4 m in length and 0.25 in height) for analysis. To avoid interferences caused by design, both probes were attached to the same Fourier transform-NIR instrument (Matrix-F, Bruker Optics), and spectra were acquired in the range 834.2-2502.4 nm using the same settings. Two different strategies for recording reference spectra were followed in each case (before the first scan and either after every measurement or after every set of 10 measurements). Noisy regions and spectral repeatability were assessed as a first step towards the evaluation of the feasibility of these probes for performing on-site analysis.
