We scream for ice cream

The job of a food chemist consists mainly in the study of chemical processes and interactions of all biological and non-biological components of foods, and in the evaluation of the chemical content of edible ingredients and whole foods. Sometimes, we also add some joint research with our food technology fellows as in this occasion, in which we have evaluated the impact of three phospholipid emulsifiers (soy, milk and rice phospho-lipids) on physicochemical, thermal and flavour characteristics of a basic Italian gelato formulation in comparison to those of mono- and diglycerides of fatty...

New project: LS9 and Washington Red Raspberry Commission

New project: LS9 and Washington Red Raspberry Commission

New research grants for the LS9 crew, a nice way to start 2014. Raspberries are especially rich in anthocyanins and ellagitannins, most of which after consumption pass from the small to the large intestine where they are subject to the action of the colonic microflora. So why do not study their actual potential nutritional and health benefits? That’s what we will make next year, with the help of a research grant awarded by the...

Tanning tomatoes

Considerable efforts are being made to increase nutraceutical levels in fruits and vegetables. Thus, in a follow-up of a paper previously published, we have assessed the possibility of enhancing phenolic and flavonoid concentration in tomato (Solanum lycopersicum L.) fruits by post-harvest irradiation with UV-B light. Fruits of the commercial cv Money Maker (MM) and the mutant genotype high pigment-1(hp-1), constitutively rich in these compounds, were harvested at mature green and turning stages and left to ripen within climatic chambers where they were daily treated with UV-B radiation (1 h,...

Mapping the chestnut germplasm

Mapping the chestnut germplasm

A proper mapping of intraspecific variability is a key step in the evaluation of biodiversity and is quite relevant when a food source is gathered from forest management of semi-wild trees, as in the case of chestnut. However, the large existing genetic patrimony is increasingly at risk of genetic erosion and it is extremely important to study and valorize local germplasm in order to preserve the existing biodiversity and to identify potentially useful characters. The widespread diffusion of Castanea sativa occurred in the course of millennia, due to both natural and anthropic causes, even in...

The phytochemical profile of a less-known american berry: Vaccinium floribundum

The phytochemical profile of a less-known american berry: Vaccinium floribundum

We like new things, new fruits and original sources of plant bioactives. This time we have profiled a new interesting berry coming from Ecuador, locally named mortino, aka Vaccinium floribundum Kunst for the botanist. Given the market value and the interest on bilberry for a number of health purposes, we have compared the phytochemical profile of V. myrtillus (common bilberry) and V. floribundum. A new HPLC-UV/DAD, MS and MS2 method was set up, validated and applied. Berry extracts obtained from V. floribundum  and  V. myrtillus  showed typical fingerprints of their phenolic secondary...
