“…These products, which include shaped and bulk solids, semisolids, liquids and gases (Table 1), have been termed structured products, [7][8][9][10][11][12]14,32 engineered products, 24 dispersed systems, 37 chemical-based consumer products 38 or formulated products (as in this article). More recently, Voncken et al 35 introduced the notion of product technology in an attempt to bring a broader designation to product engineering in the chemical engineering context.…”

“…For cases, such as that of systems involving solids, in which the underlying physical phenomena are poorly understood, empirical models can be determined through applied statistical approaches. 38,49 The idea of a chemical product pyramid is introduced in this article to systematize the relationships between the product recipe, materials' physico-chemical properties, process variables, product structural attributes, usage variables and product quality factors ( Figure 5). The base of the three-sided pyramid is defined by the materials space, process space and usage space, which determine the chemical product space occupying the top of the pyramid.…”

“…However, to design an optimal biorefining process also the specific physico-chemical properties of the individual final products need to be considered. The latter has been the focus of the product design methodologies (69)(70)(71)(72). Thus, both product and process design methodologies need to be used.…”

Sugar beet leaves: from biorefinery to techno-functionality

Sugar beet leaves (SBL), which are a side stream of the sugar beets cultivation, are currently left unexploited after sugar beets have been harvested. The general aim of this thesis was to study the biorefinery of SBL, with a special focus on the isolation of proteins. To reach this aim the research was divided into three sub-aims: 1) to determine whether there is variability in the chemical composition of the leaves due to pre-harvest conditions (plant age), 2) to evaluate the variability of the techno-functionality of leaf soluble protein concentrate (LSPC) due to system conditions and 3) to extend current product and process synthesis approaches to enable the design of biorefining process. To address the first aim, SBL collected at different time points were used. Despite a small variation in the chemical composition of the leaves of different plant ages, a large effect of the plant age on the quality of LSPC was observed. In particular, LSPC from old plants was brown (indicative of polyphenol oxidase -PPO -activity), whereas LSPC from young plants was yellow. Based on these data, samples extracted with sodium disulfite (to inhibit PPO-mediated browning) were used for further experiments. The obtained LSPC consisted mainly of protein (69.3% w/w db (N•5.23)) and carbohydrates (5.1% w/w db; half of which was charged carbohydrates). The main protein present in LSPC was Rubisco. The emulsion and foam properties of LSPC were studied as a function of protein concentration (Cp), pH and ionic strength (I). The minimal Cp of LSPC needed to form a stable emulsion (Ccr) was comparable to that of other widely used plant proteins, such as soy protein isolate. A critical ζ-potential (ζcr ~ 11 mV) was identified, below which flocculation occurs. At pH 8.0 and high I (0.5 M) the Ccr was higher than at low I (0.01 M), which relates to a higher protein adsorbed amount at the interface (Γmax). The foam ability (FA) of LSPC increased with Cp at all conditions tested. The FA was related to the soluble and not to the total Cp in the bulk. Interestingly, the minimal Cp; i.e.CcrFA needed to reach highest FA was constant as a function of pH. At high I (0.5 M) LSPC had higher FA than at low I (0.01 M), which was related to the faster adsorption of proteins at the interface. A minimum Cp was required to form stable foams. At pH 3.0 and 5.0 the foam stability of LSPC was higher than at pH 8.0. This was postulated to be due to formation of aggregates (between proteins or between proteins and charged carbohydrates). From these data it was shown that the techno-functional properties of LSPC could be linked to the molecular and interfacial properties of the dominant proteins in the concentrates. Thus, predictions for the techno-functional properties of impure systems, such as LSPC, can be made using only the known molecular properties of the dominant proteins and a small set of experiments. The knowledge acquired through the previous studies was used to adapt an existing methodology; namely the product-driven-process synthesis (PDPS...

Today's chemical industry has goals that range from commodity chemicals to diverse high value added engineered chemical products, such as an exfoliating gel, a disposable nappy or an artificial heart valve. In response to these goals, chemical product engineering has been emerging within chemical engineering. In this chapter, chemical product engineering is described as a body of knowledge structured in terms of three main pillars: the chemical product pyramid; chemical product design and process design integration; and multifaceted multiscale approach. According to this conceptual model, these pillars support chemical product design as the central objective and operational facet of chemical product engineering. A six step template for chemical product design is also presented here. This template starts with the identification of the customer needs a successful product must be able to satisfy, followed by the translation of these needs into objective, quantitative terms. It then proceeds to the generation and selection of alternative product ideas, culminating with the full specification of the product functionality and characteristics. As chemical product engineering increases in importance, it needs systematization and heuristics, just as the well‐established traditional process engineering field has. Chemical products are immensely varied and the conceptual model and template discussed here do not offer a panacea; but they provide a framework within which thinking and practice are possible.
