Critical Reviews Should Illuminate a Path Toward Impactful and Fruitful Lines of Research
21 February 2022
Laura L. McConnell, Coralia Osorio Roa, and Thomas F. Hofmann
Imagine you are lost in a dark, dense forest with no guide to find your way through to safety. Luckily you find a small flashlight that allows you to see a path forward. With this flashlight, you can quickly find your way out instead of spending hours fumbling in the dark. An excellent review paper can serve as a flashlight for the scientific community to illuminate a path toward fruitful lines of research or to reveal research gaps in need of attention. Careful analysis of the literature may also reveal new more efficient pathways toward solving a difficult problem. Thus, a review paper can help scientists to focus on solving problems at the forefront of science while avoiding research that may lead to a dead end. In the writing of a review paper, it is especially important to spend a significant amount of time considering and crafting the conclusions and future recommendations in your Perspectives for Future Research section. This section is where the real impact of the review comes into focus, allowing you to shine a light toward the future and stimulate new research approaches.
A recent editorial by Skrabalak in Chemistry of Materials suggests that review articles should be original, timely, and authoritative and perhaps inspire new directions in a field. An editorial from many decades ago by Hart suggested that a “review will not only provide a summary of the state of affairs ..., but will also pinpoint the problems which still need attention and, ... will set (the reader) off in the “right” direction”. Some recent reviews from Journal of Agricultural and Food Chemistry, ACS Food Science & Technology, and ACS Agricultural Science & Technology are highlighted to provide examples of review papers that provide a clear path forward for readers.

Spicy substance from pepper gets into breast milk after eating
Spicy breast milk?
25 November 2021
In part of a recent human study led by the Technical University of Munich (TUM), it was found that after eating a curry dish containing pepper, piperine - an alkaloid responsible for the pungency of pepper - was present in the milk of breastfeeding women. The findings help decipher mechanisms that shape our food preferences from infancy.
Breast milk is the first food that babies consume. Various studies have suggested that the “taste experience” in early childhood influences eating behavior in adults. Unlike standardized infant formula, natural milk does not taste and smell the same every day. The differences are largely due to the maternal diet.
Graduation Sara Marquart
18 November 2021
Congratulation to Sara Marquart for the successful oral examination of her PhD thesis. Sara Marquart graduated on stable isotope experiments and quantitative studies on the formation of unknown bitter compounds in roasted coffee, and earned the title "Dr. rer. nat.".

Influenced by Breast Milk
How do food preferences develop? An intervention study using curry as an example is dedicated to examining the transfer of flavour compounds into breast milk
A traditional German expression for something acquired very early in life is that it has been “absorbed with mother’s milk”. This figure of speech is worth reflecting upon, also in the literal sense and from the point of view of various scientific disciplines, which are seeking clarification based on hard biochemical facts and data. What else does a baby absorb with breast milk, apart from the vital macroand micronutrients it contains? It appears to be the case that many habits and skills have their origin in early childhood. Sensitive time frames in human development are well-known with regard to language acquisition, but similar phenomena can be observed regarding the acceptance of foods.
Graduation Silvija Abakuks
16 September 2021
Congratulation to Silvija Abakuks for her successful oral examination of her PhD thesis. She attained the title "Dr. rer. nat." with studies for the characterization of bitter and pungent tastants in native olive oil extra and investigations on the formation of oral lipid films on its consumption.

3rd winner of the TUM IdeAward 2020
Congratulations to our colleague Christian von Heynitz and the team SIDERION for winning one of the TUM IdeAwards 2020!
The Technical University of Munich (TUM) and its Affiliated Institute UnternehmerTUM, Europe's biggest Center for Innovation and Business Creation, promote start-ups from science in an eco-system unique in Europe. A central element in this facilitation and support structure is the TUM IdeAward, which has been presented to the best start-up ideas at the university since 2012. TUM and UnternehmerTUM award the prize jointly with the Zeidler Research Foundation, which provides the cash prize amounting to a total of 37,500 euros.
At yesterday's online event, which was followed by more than 800 viewers in the livestream, ten teams presented their founding ideas - three of them received awards.
Solid-liquid reactions play a key role in all process industries, especially in the pharma and water treatment sector. Thereby, (bio) chemical or physical interactions between a liquid and a particulate solid phase take place by means of material transport. However, established procedures harbor procedural weaknesses limiting the transport rate and thus the techno-economic efficiency: process time, footprint, use of resources and waste generation are currently far too high. This is due to the limited usability of small solid particles, which, however, are desirable due to the higher interaction surfaces. SIDERION solves this problem with a highly efficient rotating bed reactor. The innovative essence is the use of a planetary gear to generate periodic centrifugal forces, which keep the particles in an oscillating motion and prevent clogging of the particle bed while maximizing the transport rate. Therefor the reactor chamber rotates around its own axis while moving on a circular path; like the earth does around the sun.

Der Lebensmittelsektor - Aufbruch in ein neues Jahrzehnt
Die aktuelle COVID-19-Pandemie hat eindrucksvoll vor Augen geführt, wie wichtig die Lebensmittelversorgung für das Gemeinwohl ist. Hemmungslose Hamsterkäufe machen deutlich, wie Krisensituationen unsere gerade in den Industrieländern als selbstverständlich empfundenen Grundbedürfnisse wieder in den Mittelpunkt rücken.
New method for quality control of chanterelle mushrooms
Chanterelle mushrooms as a taste enhancer
June 30, 2020
Chanterelles give savoury dishes a rich body and a unique complex flavor. Experts refer to this as the kokumi effect. A research team from the Technical University of Munich (TUM) and the Leibniz-Institute for Food Systems Biology recently developed the first method to clearly quantify chanterelle-specific key substances that contribute to this effect. This method can also be used for quality control.
Chanterelles (Cantharellus cibarius) are one of the most popular mushrooms in Germany. Depending on the weather, chanterelle season starts in early July. Connoisseurs value the mushroom’s delicate fruity aroma, which is reminiscent of apricots, and its aromatic and slightly bitter taste profile. Not only do chanterelles have a unique flavor profile, they also function as taste enhancers, lending dishes a well-rounded mouthfeel and a lingering, rich flavor.

The kaleidoscope of good taste
Some foods contain several dozen chemical substances which determine their taste. Separating them from each other and identifying them is a Sisyphean task to which the team working with food chemist Prof. Corinna Dawid has dedicated itself. The researchers work with a mixture of measuring equipment and human tongues.
Der Eintrag von Mikroplastik in Lebensmittel und die Aquatische Umwelt und seine Folgen – aktuelle Fragen und Antworten
Das Thema Mikroplastik erfährt große Aufmerksamkeit in der Bevölkerung, die nach Aufklärung zu den damit in Zusammenhang stehenden potenziellen Gefahren verlangt. Bedingt durch die komplexen und uneinheitlichen analytischen Nachweis- und Quantifizierungsverfahren fehlen jedoch bislang vergleichbare Daten zur Menge von Mikroplastik in der Umwelt oder in Lebensmitteln. Gleichzeitig ist eine fundierte Risikobewertung, aufgrund teils widersprüchlicher Ergebnisse, aktuell sehr schwierig. Beides steht im Fokus von „MiPAq“, einem Forschungsprojekt mit Industriebeteiligung an der Technischen Universität München.
