Abstract:

Purpose of review: There has been in the recent years a renewal of interest in the texture of pureed plant foods, in particular, with a more widespread application of shear-thinning rheological models and their use beyond the more classical commodities (tomato, potato). This review provides an overview of these models and identifies in which manner the more recent works (roughly 2000-2007) complete or enhance our understanding of these products.

Recent findings: Transgenic tomatoes have been used to better understand the effects of processing on serum viscosity (pectolytic enzymes) and have given intriguing results on the factors of cell-cell adhesion. Due to the development of convenience foods, the impact of freeze/thaw cycles on texture and syneresis has been studied. Alternative technologies have received little attention, except isostatic high pressure. As pectolytic enzymes have proved to be rather resistant to pressure inactivation, HPP appears to be of limited practical interest so far. Remarkably, few articles have addressed the consumer and his perception of the texture of pureed foods.

Directions for future research: Fundamental advances are needed to help understand inhomogeneous flow behaviour and the response at the tissue and molecular levels of fruits/vegetables during processing. Better descriptions of steady flow and dynamic rheological behaviours and of the impact of freeze/thaw cycles can be useful for the food processing industry.
