Industrial relevance: Consumer demand for high quality pineapple puree with minimal processing explores the
possibility of applying high pressure processing (HPP) as an alternative nonthermal processing to this product.
On the other hand, association of moderate temperature (30–70 °C) with high pressure is necessary to inhibit
the enzymatic spoilage in the product. Though HPP at moderate temperature ensures the product safety and longer
shelf life, the impact on process parameters on the nutritional and other organoleptic properties of the product
cannot be neglected. Detailed study on the effect of high pressure process parameters viz. pressure,
temperature and treatment time on the nutritional quality attributes is needed prior to the optimization of
HPP conditions. Developed RSM models to each quality attribute will quantify the changes happening during
HPP combined with moderate temperatures.
