PASSION FRUIT BY-PRODUCT: PROCESS DESIGN OF PECTIN PRODUCTION

Optimization of Pectin Extraction from Passion Fruit Peel using Response Surface Methodology

Pectin from passion fruit peels was extracted using citric acid extraction. The effects of citric acid concentration from 0.05 to 0.21 % (wt/wt), extraction time from 30 to 120 minutes and extraction temperatures from 35 to 85 ̊C on pectin yield and the degree of esterification (DE) were investigated. Using the central composite design (CCD), the optimized pectin yield was 6.44 % and degree of ...

BPMN Process Design for Complex Product Development and Production

In automotive development a lot of new power engine concepts were developed. Beneath the combustion engines hybrid drive systems and electric engines were developed. Consumers, public institutions and politics demand alternative drive systems to avoid air pollution, noise and the consumption of oil resources. Therefore electric drive products with innovative technologies were developed addition...

Product Centered Process Design

Fruit softening and pectin disassembly: an overview of nanostructural pectin modifications assessed by atomic force microscopy.

BACKGROUND One of the main factors that reduce fruit quality and lead to economically important losses is oversoftening. Textural changes during fruit ripening are mainly due to the dissolution of the middle lamella, the reduction of cell-to-cell adhesion and the weakening of parenchyma cell walls as a result of the action of cell wall modifying enzymes. Pectins, major components of fruit cell ...

Detection of a resistance gradient to Passion fruit woodiness virus and selection of 'yellow' passion fruit plants under field conditions.

Productivity of 'yellow' passion fruit (Passiflora edulis Sims. f. flavicarpa O. Deg.) is reduced by infection with Cowpea aphid-borne mosaic virus (CABMV). We examined resistance in 72 yellow passion fruit plants grown from open-pollinated commercial seed. Plants were mechanically inoculated with CABMV virus and maintained in the field in order to select contrasting genotypes for resistance. I...
