Reducing and replacing fat, sugar or salt without losing enjoyment
Consumers are more aware of, and knowledgeable about, their health than ever before. This increased focus has led to people following a variety of different diets, with a wide range of dietary specifications, putting pressure on manufacturers to develop a portfolio of foods to meet individual needs. New regulations are also being introduced in parts of the world where the marketing of foods high in fat, sugar and salt presents a challenge for food manufacturers, many of whom are facing pressure to reformulate existing products, particularly in bakery, desserts and snacks.
While consumers are eager for healthier (plus more ethical and environmentally friendly) foods they also expect the “same-as” eating enjoyment as they get from the foods they know and love. The reduction (or addition) of any ingredient presents a number of taste and texture challenges for manufacturers that then need to be tackled to bring them in-line with consumers’ sensory expectations.
Shelf life and food quality are also important considerations, as ingredients such as salt and sugar can act as preservatives. Consumers may be willing to accept a slight change in texture or flavour if the health benefits and overall sensory experience are strong enough. You may want to take advantage of cross-modality between taste and texture, for instance, using vanilla’s “creamy” taste to improve mouthfeel in low-fat products or you may even want to consider processing steps such as fermentation to improve the product’s texture, robustness and shelf life.
Texture problems associated with Low-in Foods
Low-fat without low-quality
However, fat plays a huge part in the consistency of dairy foods, especially yoghurts. As well as different expectations across the globe, perceptions and preferences are changing. Thick, creamy products – easily achieved with high fat content – evoke luxury and decadence but there is still sizeable demand for thinner, more traditional products, especially in developing markets.
制造商经常有动机去除脂肪from food products, but when something is removed from a recipe, it inevitably has to be replaced with another ingredient. Sometimes that replacement is another type of fat, or it might be another ingredient altogether (to reduce the overall fat content of the food). Food manufacturers have to test the altered food in comparison with its original form to ensure that all textural properties remain the same within acceptable limits.
Staying firm on sugar reduction
However, beyond adding a sweeter taste, the reduction or removal of sugar also impacts the texture of foods which must be addressed. Jam, for example, relies on sugar for firmness. Whether being spread on toast or added to cakes, the firmness of jam is crucial to consumer enjoyment and has a direct impact on its perceived quality. Jam is not the only food that can find its texture being changed by a reduction in sugar. Chewing gum is another product that is often developed with a ‘sugar-free’ option, particularly due to dental health concerns, but again, replacing sugar with substitutes has wider implications for its texture. More specifically, the hardness, flexibility and stickiness of gum can all be affected by the change in sweetening agent. For example, mannitol can be used to improve mechanical strength.
Bread is responsible for up to a fifth of daily salt intake, making baked foods a clear opportunity for salt reduction reformulation in many western markets. However, salt is pivotal to dough strength and stickiness, which is required for the desired crumb structure of the final product and also to hold the folded layers of dough together, ensuring consistency of aeration in the baked bread. Bakers have to tread a fine line: excessive stickiness causes processing difficulties, but if cutting salt content also leads to a weakening of the dough, problems of a different nature, but equal importance, become evident. Additionally, salt tightens the gluten structure and helps loaves retain the carbon dioxide gas formed during fermentation. This has a great impact on volume after baking. As a result, lowering salt content can lead to smaller, less attractive breads. Using a Volscan Profiler, can help to provide quantifiable volume and density measurement and, again, can be used as a comparative tool during reformulation.
How Texture Analysis can help in Low-in Food development
一个s consumers become more demanding and reduce further their purchases of foods containing ingredients they deem unhealthy, the need for revisiting recipes is set to grow. Understanding how these reformulations can impact finished products is crucial to minimising adverse textural effects and identifying strategies for retaining the mouthfeel people love.
There is a clearly huge amount of trial and error (or an iterative approach) involved in developing and assessing new formulations. When reformulating your products you will be looking for changes that show as little impact as possible. Understanding the impact on texture, and the potential implications of these texture changes, is crucial in ensuring new product launches aren’t a miss with consumers. So, what can manufacturers do? Consistent, objective measurement is vital for informing reformulation and new product development, in addition to maintaining high quality standards.
Texture Analysis is a mandatory stage in the Research and Development of ingredient-substituted products, when texture can be altered by the addition of different quantities of ingredients, and must be measured after each iteration of ingredient or process modifications. Stable Micro Systems manufactures instruments that measure the tensile and compressional properties of raw ingredients, individual materials and finished products. It is important to measure the textural properties of food to ensure they match the expectations of a consumer. As with any manufacturing innovation, a large amount of research takes place during development, but the end product must also go through a quality control process to assess its mechanical (and sensorial) properties. ATexture Analyser是此过程的关键部分，通过应用压缩，张力，挤出，粘附，弯曲，弯曲或切割测试来测量其测试产品的可靠方法雷电竞app官方下载 S，例如牢固，粘性，脆和弹性，仅举几例。

一个Texture Analyser also provides the ability to test chewing gum at various stages of its life, from the initial bite to the first few chews and beyond. Measuring through the final chew stage ensures a better understanding of consumer experience, and comparisons to gums with added sugar can clearly show the changes the formulation can cause.
To gauge the impact of a salt reduction programme on dough quality, for example, samples can be prepared and tested prior to bulk preparation using a Warburtons Dough Stickiness System to identify the ideal formulation.

Examples of how Texture Analysers have been applied
一个round the world there have been several pieces of research published in the areas of dairy, confectionery, bakery and meat products – all known for their popular high calorie offerings and all looking for solutions to offering a lower fat/sugar counterpart without a textural compromise. Here’s how they’ve applied their Texture Analyser.
