“…Promising methods, some of which are already being used routinely, relate to the detection of animal commodities, such as meat, dairy products, fish, and shellfish with regard to the detection of the geographical origin, the feeding method of the animals, the production method (organic vs conventional) or whether it is wildlife or breeding [155]. In addition, there are numerous examples of applications for plant‐based foods, which mainly refer to the proof of geographical origin, the fertilizers used, and the botanical origin, for example for hops [156], ginseng [157], and tomatoes [158].…”

In times of increasing globalization and the resulting complexity of trade flows, securing food quality is an increasing challenge. The development of analytical methods for checking the integrity and, thus, the safety of food is one of the central questions for actors from science, politics, and industry. Targeted methods, for the detection of a few selected analytes, still play the most important role in routine analysis. In the past 5 years, nontargeted methods that do not aim at individual analytes but on analyte profiles that are as comprehensive as possible have increasingly come into focus. Instead of investigating individual chemical structures, data patterns are collected, evaluated and, depending on the problem, fed into databases that can be used for further nontargeted approaches. Alternatively, individual markers can be extracted and transferred to targeted methods. Such an approach requires (i) the availability of authentic reference material, (ii) the corresponding highresolution laboratory infrastructure, and (iii) extensive expertise in processing and storing very large amounts of data. Probably due to the requirements mentioned above, only a few methods have really established themselves in routine analysis. This review article focuses on the establishment of nontargeted methods in routine laboratories. Challenges are summarized and possible solutions are presented.

“…The availability of these fruits in South Africa will enhance food production for human consumption because of their richness in essential vitamins and carotenoids ( 3 ). Three main cultivars of tomatoes are predominant in South Africa, namely, round or fresh tomatoes, Roma tomatoes, and cherry tomatoes, contributing about 24% of the total vegetable production in South Africa ( 4 ). Tomatoes are cultivated in open fields under irrigation in the following South African provinces: Eastern Cape, Western Cape, northern Kwazulu-Natal, North West, Mpumalanga, and Limpopo.…”

“…Additionally, isotope ratios of animal tissue from animals can be determined by their feed source, identity the specific feed, and distinguish whether the production was organic or conventional [ 201 ]. A smilar approach, regarding production system, has been for fruits such as tomato [ 203 ]. For a primer on principles and instrumentation, we refer the reader toward the recent manuscript by Mai and coworkers [ 204 ].…”

This review presents an overall glance at selected instrumental analytical techniques and methods used in food analysis, focusing on their primary food science research applications. The methods described represent approaches that have already been developed or are currently being implemented in our laboratories. Some techniques are widespread and well known and hence we will focus only in very specific examples, whilst the relatively less common techniques applied in food science are covered in a wider fashion. We made a particular emphasis on the works published on this topic in the last five years. When appropriate, we referred the reader to specialized reports highlighting each technique’s principle and focused on said technologies’ applications in the food analysis field. Each example forwarded will consider the advantages and limitations of the application. Certain study cases will typify that several of the techniques mentioned are used simultaneously to resolve an issue, support novel data, or gather further information from the food sample.
