Raw material quality

The quality of biological raw materials often vary widely because of seasonality, climate, growing conditions, genetic differences between varieties and storage conditions. When these raw materials are used in the food industry, the quality of the finished product will also vary. Variations in quality will in turn cause reduced earnings due to suboptimal processing, more wastage and dissatisfied customers.

Customers have clear expectations about a product's taste and consistency, and it is important for the industry and supermarkets to meet these expectations. It is therefore crucial for the food industry to have detailed knowledge about the various aspects of raw materials' quality and how raw materials can be used most effectively in processing and distribution- in terms of finance, sustainability, health and environment.

Variations in quality must be monitored at an early stage

Variations in raw materials quality can accelerate during subsequent processing, if processing and storage are not properly monitored and controlled. The food industry needs to record such variations as early as possible in the production process chain and to compensate for variations by adjusting processing conditions or formulaes. In this endeavour it is essencial to carry out measurements of raw materials quality both before and during production itself - preferably right at the production line. Rapid spectroscopic measurement methods are highly suitable for this purpose, as they have the potential to record both chemical and physical properties of raw materials and products.

Inter-disciplinary competence

Knowledge about raw materials and measurement of their quality properties is an area of high priority throughout Nofima, as the knowhow can be utilised efficiently across the different disciplines and raw materials groups. Nofima Mat has laboratories with advanced analytical instruments and an internationally recognised sensory panel to assess products on the basis of taste, aroma, texture and colour.

Carbohydrates

Carbohydrates are important constituents of food which contribute to texture and flavour.

Cereals

Variations in cereal quality are significant for both technological and health related properties. Nofima Mat focuses particularly on wheat, barley and oats.

Fat and oils

Fat (lipids) is a complex and important constituent of food and is of great significance to food's taste, texture and energy. Fat can be divided into saturated and unsaturated fat. Saturated fat comes primarily from animal products such as butter, cream, meat etc. Unsaturated fat comes primarily from fish and vegetable products such as plant oils, nuts etc.

Fruit, berries and vegetables

Research results show that a healthy diet is rich in "greens" - food based on plant raw materials such as fruit, berries, vegetables, pulses, plant oils, herbs and nuts.

Meat

Consumers are very aware and critical regarding the quality of meat products. The meat should be lean, tender and juicy, and the colour and visual appearance are equally important. A further requirement is that meat should be quick and easy to prepare. Ethical aspects of husbandry, transport and slaughtering are of increasing concern to the public.

Proteins and proteomic

The significance of proteins for the quality of meat, fish and bakery goods is an important research area at Nofima Mat. The composition of proteins is important for the functional properties and the end product quality of the raw materials.

Seafood

The raw material quality of seafood embraces appearance, taste, texture and hygienic and nutritional properties.
