In today’s contemporary world, a healthy diet has become one of the top priorities for health-conscious consumers as they realize that excessive dietary fat intake over time can lead to weight gain and non-communicable diseases like cardiovascular disease, diabetes, stroke and cancer12.
According to the IFIC Consumer Research, more than 35% of respondents are looking for low-fat and reduced-fat food products. This is especially more apparent in the elderly age group and better-educated community who shows more interest in “low in saturated fat” labelling3. The rising health awareness of consumers is indeed driving the interest and overall acceptance of low-fat food products in the commercial market5.
Margarine was created as an inexpensive alternative to butter with similar properties5. It behaves as a water-in-oil emulsion of which the traditional margarine generally comprises of 70-80% of fat6, while reduced-fat and low-fat spreads typically contains approximately 60% & 40% of fat respectively10. It is widely recognised that fat plays a crucial role in food by providing a desirable flavour, taste and mouthfeel, and its reduction may lead to unfavourable qualities7. The trend for healthy eating is expected to continue and it will be a key factor for the reformulation of low-fat products to taste just as good as the original versions by incorporating suitable fat replacers7.
Inulin – An ideal fat replacer?
Inulin, is a soluble prebiotic fibre that is commonly found in chicory roots6. Inulin is not only applied to food products as a sugar replacement, but also serve as a fat replacer. When inulin is thoroughly mixed with water, it forms an inulin gel with a creamy texture and an appropriate consistency which can be easily incorporated into low-fat food products to create fat-like mouthfeel1.
A recent study has examined that low-fat margarine, through substitution of 40% of inulin gel contributes a smoother texture with good spread ability and appears to have optimal sensory attributes. It is worth noting that the appearance of the margarine gets lighter and had no significant effect on the aroma as the content of inulin increases. Overall, it retained the characteristics accepted by consumer as with full-fat margarine6. For low-fat processed cheese spread, addition of 5-6% inulin offers fat-like mouthfeel and enhanced creaminess, as well as good spreadability4,8.
Fats out, Fibre In
In addition to inulin acting as a fat replacer in low-fat margarine and spreads, inulin is also used in the development of functional foods due to its beneficial role in gastrointestinal health9. Studies suggest that inulin-type fructans had a significant bifidogenic effect and could improve gut microbiota composition2. Furthermore, inulin has been shown to improve bowel function through increasing stool weight and softer stools which help relieves constipation11.
Heightened health concerns have shaped consumers’ food preferences making them more inclined to consume low-fat products in order to maintain a healthy body and lower the risk of various chronic diseases. Hence, the food industry these days are leaning towards the production of low-fat products by using fat replacers. The unique techno-functional properties of inulin as a fat replacer, make it the better option in developing good-tasting, indulgent low-fat products, with added prebiotic function.
