Image analysis for muscle fiber structure assessment

The microstructure of foodstuffs has a direct impact on the organoleptic properties. At HISTALIM, we have developed a histological method for quantifying the morphological changes of the muscular fibres (Meat Destructuration Indicator: MDI) enabling the classification of meat and bone raw materials. This image analysis tool is the only COFRAC accredited quantitative histological method of analysis in Europe.

Assessment of GonadoSomatic Index (GSI) in oyster

The determination of the gonadosomatic ratio (percentage of the body volume of the animal occupied by the gonad) makes it possible to follow the smooth continuity of reproduction in molluscs in livestock farming.

It is also used in research for selecting the oysters which spend their energy in growth rather than in reproduction, thus making it possible to obtain oysters of larger size more quickly. It is also important to know if the oysters selected for their growth can or cannot reproduce in natural environment.
