Fermented low salt and low fat dairy foods, such as cheese and yoghurt, with great taste – this is possible with the rational design of improved, tailor-made industrial cultures with attractive flavour forming properties. Various tools and model systems for directed screening for flavour producing (starter) organisms are now available for enabling successful selection of strains…

Due to an ever-growing population, proteins extracted from existing agricultural side-streams are of high interest for food processors. RuBisCO, being the most abundant protein in the world, is a very good candidate for food applications. However, up to now, the greenish colour associated with RuBisCO preparations made consumer acceptance very difficult. NIZO food research has developed a simple and up-scalable extraction process for RuBisCO yielding to a colourless protein isolate with a high percentage of undenatured protein (Figure 1 opposite). Moreover, the protein isolate displays promising techno-functional properties, such as a high foam volume and stability and a heat-induced gelation at low protein content (two per cent w/w).

Foods are eaten not only for their nutritional value but also for the pleasure of eating. Food producers reformulate their products to comply with consumer trends on fat, salt and sugar reduction as well as to reduce the number of additives. The number one goal is to maintain consumer acceptance. Understanding the role and interactions of ingredients in the texture and stability of foods is of key importance to develop improved food products. This article describes the role of microstructure in understanding the ingredient functionality in food products.
Composite food products are complex products composed of a wide range of ingredients. The three main ingredients (also called macronutrients) are proteins, carbohydrates and fats/oils. The type or origin of the ingredients, their concentrations and the applied processing determines the final product properties and sensory profile. For example, milk can be transformed into different products such as yoghurt, cheese, butter and desserts just by changing processing and ingredients.

In the food industry, it is possible to use new breakthrough technologies to create a more sustainable production process combined with a substantial decrease of production costs. However, the development of these technologies requires a significant investment of time and money. The latter, in particular, is difficult to secure these days. Fortunately, there are some relatively simple measures available to decrease production costs by five to 10 per cent within a single year. Five are presented in this article. In order to obtain a maximised effect it is important to apply all five to achieve optimal production efficiency.

Most of the powder products available on the market are produced using a spray drying process. Drying processes are known to be the most energy consuming processes used in the food industry. For example, the Dutch dairy industry required 1.4 PJ for drying its whey and milk powder in 2007. Therefore, a reduction of the energy consumption in drying processes will result in large cost savings, a better carbon footprint and a more sustainable production chain.

Consumer awareness of additives drives the industry to launch natural and/or clean label products. Products without added flavours and colourings or with only natural flavours and colours are well known in the market. However, further cleaning of the product label is thorough as it focuses on functional additives and texturising ingredients, such as stabilisers, thickeners, emulsifiers and preservatives. Research at NIZO food research demonstrated that proteins are a unique source of clean label ingredients with opportunities to tailor their functionality, not only as texturising ingredients but also as preservatives.
Drying processes in the food industry often operate at a suboptimal level. The most important reason for this is that to obtain optimal drying, a complex balance must be found among variables such as energy costs, product quality, dryer design and safety. Therefore, there is a need for a systematic approach and concrete solutions. NIZO food research has developed a step-by-step optimisation approach that not only makes use of process and product scans, but simulation techniques such as CFD (Computational Fluid Dynamics).

Chocolate, in its various forms, is the ultimate pleasure food for many customers. New chocolate flavoured products are constantly being developed such as drinks, dairy, ice-cream, and desserts with greater taste and greater convenience.
Spray drying is an essential unit operation for the manufacture of many products with specific powder properties. It is characterised by atomisation of a solution or suspension into droplets, followed by subsequent drying of these droplets by evaporation of water or other solvents. Spray drying is used for the manufacture of many consumer and industrial products such as instant food products, laundry detergents, pharmaceuticals, ceramics and agrochemicals. The best known example of an instant food product is milk powder, but instant beverages such as coffee can also be produced by spray drying.
