Spicy substance from pepper gets into breast milk after eating

Spicy breast milk?

Novemeber 25, 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.

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.

Team SIDERION

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.

SIDERION

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.

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.
