Functional lipids in beverage products

Issue 3 2016  •  30 June 2016  •  Guillermo E. Napolitano, PhD, Expert Scientist, Nestlé Development Center

The last decade has witnessed an extraordinary surge in the development of beverage products containing healthier oils and nutritionally active lipid ingredients. There has been a significant shift from the use of relatively unhealthy, but chemically stable, fats rich in saturated and trans fatty acids (TFA), to healthy and chemically unstable oils rich in unsaturated fatty acids. As a consequence, research resources also shifted from the more conventional aspects of the physico-chemical properties of bulk fats to more complex problems of lipids oxidation in bulk, disperse phases and oil in water emulsions…

Fat functionality in emulsified foods

Issue 5 2015  •  28 October 2015  •  Geoff Talbot, The Fat Consultant

An emulsion is a fine dispersion of liquid droplets in another liquid continuous phase in which the droplets are immiscible or insoluble. In food terms, the two phases are generally oils and water. Food emulsions tend to take one of two forms – either oil in water (O/W), e.g. cream and mayonnaise, or water in oil (W/O), e.g. butter and spreads – although more complex duplex emulsions such as water in oil in water (W/O/W) and its opposite oil in water in oil (O/W/O) are also possible. In simplistic terms, water is water but oils can differ in their properties and functionality so what is the best oil to use for a specific food emulsion? In this article, the basic properties of fats that play a role in this choice will be described and how these are important in food emulsions will be discussed…

The art of oil processing consistency

Issue 2 2015  •  23 April 2015  •  Emma Woods, Technical Manager, Phoenix Speciality Oils

Ensuring consistency during the production of high quality, extra virgin cold pressed oils doesn’t begin at the pressing or filling lines – it starts years before that. The actual process of creating seed oils isn’t that complicated. Seeds get pressed, solids get removed and the remaining oil is then filtered down to at least the FSA’s minimum level of purity. Beyond that, there’s not a huge amount of processing effort required – just filling into bottles, packing for transit and then despatch. The reality for manufacturers of cold pressed rapeseed oil, like many other food producers, is that the hard work involved in producing high quality, natural, consistent fast moving consumer goods begins long before the materials arrive on site for processing, two, three or four years before…

A novel approach to reducing the total and saturated fat content of baked goods

Issue 1 2014  •  5 March 2014  •  Charles Speirs, Bakery Science Manager, Campden BRI

In 2008, the Food and Agricultural Organisation and the World Health Organisation reviewed their recommendations on dietary fat and fatty acids in view of the growing evidence on dietary fatty acids and health outcomes. The key recommendation was that our diet type should change to limit the saturated fatty acid content to 10 per cent of the dietary energy intake. The saturated fatty acids should be replaced with polyunsaturated fatty acids. By adjusting the ratio of saturated to unsaturated fatty acids in the diet, the level of low density lipoprotein cholesterol in blood serum is reduced, which correlates with a decrease in the risk of coronary heart disease…

Trans fats in foods and the commercial challenges

Issue 4 2013  •  28 August 2013  •  M. S. Alam Head of Fats and Oils Program, Food Protein R&D Center, Texas A&M University

Fats and oils are major sources of energy, providing nine kilocalories per gram compared to carbohydrates and proteins which provide only four kilocalories per gram and 3.8 kcal/g of energy, respectively. The two major sources of edible fats and oils are plants and animals. Plant sources or vegetable oils are found in abundance in seeds and fruits such as soybeans, cottonseeds, canola, sunflower, corn, peanuts, palm, palm kernels and coconut oil. The major animal fats include lards from pigs, tallow from cattle and sheep, milk fat from cows and fish oil.

The major component of most oils and fatty foods are triglycerides (95 – 98 per cent) represented as TAG whereas the fatty acids such as stearic acid (C18:0), oleic acid (C18:1), linoleic (C18:2), linolenic (C18:3), C16:0 (palm oil) and C12:0 (coconut oil) are the major building blocks of TAG. For example, in Figure 1, the TAG molecule is composed of a glycerol molecule. Attached to it are three different fatty acids, C16:0, C18:1 and C18:3. The terms mono unsaturated fatty acids (MUFA’s) and poly unsaturated fatty acids (PUFA’s) are used for fats containing one or more than one double bond. MUFA’s and PUFA’s are considered heart healthy fats if consumed in a balanced manner. Olive, soybean, canola, sunflower and cottonseed oil contain considerable amounts of MUFA’s and PUFA’s. Omega-3 fats are from the PUFA family and commonly found in most nuts (almond, cashew, walnut etc.) in fatty fishes and in plant oils such as flaxseed oil. Consuming omega-3 fats protects the consumer from heart disease and decreases the risk of many lifethreatening diseases such as diabetes and cancer.
