Using synchrotron FTIR spectroscopy to determine secondary structure changes and distribution in thermoplastic protein

Blood meal is a high protein, low value by‐product of the meat processing industry that can be converted into a thermoplastic material by extrusion with a combination of a surfactant, urea, a reducing agent, water, and plasticiser. Changes in protein structure after each processing step (mixing with additives, extrusion, injection molding, and conditioning) were explored using synchrotron FTIR microspectroscopy. Blood meal particles were found to have higher β‐sheet content around the perimeter with a randomly structured core. α‐Helices were either located near the core or were evenly distributed throughout the particle. Structural rearrangement consistent with consolidation into a thermoplastic was seen after extrusion with processing additives, resulting in reduced α‐helices and increased β‐sheets. Including triethylene glycol as a plasticiser reduced α‐helices and β‐sheets in all processing steps. At all processing stages, regions with increased β‐sheets could be identified suggesting blood meal‐based thermoplastics should be considered as a semicrystalline polymer where clusters of crystalline regions are distributed throughout the disordered material. © 2013 Wiley Periodicals, Inc.

Position of soy protein processors in relation to laws and regulations

Soy protein products in the U.S. fall under the regulatory powers of the Food and Drug Administration as far as processing plants are concerned. The U.S. Department of Agriculture controls their use in meat and poultry products. Many states have separate regulations. The industry is expected to know federal and state regulations and interpret them for the customer. Difficulties arise for the processor when there are so many different state, Food and Drug Administration, U.S. Department of Agriculture, and foreign regulations that affect the products. This Conference might spearhead world-wide cooperation in the development of future regulations.

Trends in industrial usage for vegetable oils — symposium overview

Vegetable oils are firmly established components of many industrial products and contribute a small but important share to the oleochemical and chemical industries-about 2% of total organic chemicals produced. The oleochemical industry is a mature one with low profit margins and in need of novel products and product applications, the development of which will require both basic and applied research. Several symposium participants identify areas that could add significantly to existing markets for unmodified vegetable oils, such as a diluent or enhancing agent in the application of pesticides and as an energy or heat source. Others show that considerable potential exists for new chemicals and modified vegetable oils and unique chemicals derived therefrom in value-added products such as coatings, polymers, lubricant additives or food additives, sometimes involving unique oils other than the traditional commodity mix. Without doubt, this is a time for the oleochemicals industry to invest in the future with nontraditional approaches to research and development. The oleochemical industry can and should expand its horizons, but with the realization that vegetable oils will have a lesser role compared to that of other renewable resources, such as wood and agricultural residues.

Food powders engineering, between knowhow and science: Constraints, stakes and opportunities

Food powders are presented and discussed according to food sciences specificities and according to powder engineering concepts. Food powders are very present in everyday life. They are generally obtained from agricultural raw materials by different processes such as fragmentation or spray-drying processes. Amongst the food products, the food powders are easy to preserve, transport, store, weight and process. They are used to bring specific functionalities (e.g. physicochemical stability, microbiological stability, organoleptic qualities and nutritional composition). As well as food products, food powders are complex systems that can be defined by a great dispersion in their properties caused by: (i) the complexity of the chemical composition of the agricultural raw materials; (ii) the heterogeneity of the native structures of the product; (iii) the reactivity under high temperature or water addition; (iv) the variability of the agricultural raw materials behavior. Food companies, equipment suppliers, and scientists became aware of the relevance of a global approach by integrating the food powders engineering approach (particles properties, powder reactivity, and powder processing) to the classical food sciences concepts. The aim of this article is to highlight the stakes and opportunities concerning food powder processing and particles properties.
