Taste Profiles

2 Formulating with Sweeteners

Intense sweeteners can have very special sensory characteristics. Sometimes these properties can be used directly to create products of a unique taste profile which is accepted and demanded by consumers. The focus of the development is then to avoid a special taste or in general to match a profile which is known from products sweetened with sucrose or other carbohydrates.

Records from the earliest civilization show that man has always valued foods which taste sweet. For several hundred years, sugar has been used to sweeten many of the foods and drinks we eat. With the invention of saccharin at the end of the 19th century, low calorie sweeteners offered a limited alternative. The introduction of

Aspartame and Acesulfame-K, however, created a wealth of new opportunities.

Amongst all the available high intense sweeteners Aspartame is unique in its taste profile which comes very close to sugar. Numerous taste tests have shown that people struggle to tell the difference between products sweetened with Aspartame and those sweetened with sugar. Aspartame, through its taste profile, can supply known sweet properties, without the usual expected calories. It can be used as a single sweetener or in combination with other high intense sweeteners introduction at the end of 1980’s opened a door to a new world.

The graphs show how the individual sweeteners compare to sugar. The tests were done in water. The axes show the score for the initial sweet taste and the after sweet taste, the initial and

the after bitterness, the amount of body (mouth feel) that the sweetener has, and the level of any initial or subsequent mouth-drying effect.

Single or Mix Beverages such as Cola are on the market in hundreds of variations. Amongst those a few formulations obviously have made an inter-national career and are used around the globe. Reformulating is a very difficult task. Market research has shown that consumers prefer colas sweetened with Aspartame or a high share of Aspartame when sweetener blends are used.

In a double blind consumer test of two identical colas, Aspartame outscored Sucralose in every aspect, including cola taste, sweetness, after-taste and naturalness. Respondents were more likely to buy the Aspartame-sweetened cola, and when asked to say which sample they preferred, 61% chose the sample with Aspartame.

Leading international scientific and health authorities have approved high intense sweeteners such as Acesulfame-K, Aspartame and Sucralose for the use in foods and beverages. Among these organizations are the Joint Expert Committee on Food Additives (JECFA) of the World Health Organization (WHO) and the United Nations Foods and Agriculture Organi-zation (FAO), the United States Food & Drug Administration (FDA) and the European Food Safety Authority (EFSA) Acesulfame-K, Aspartame and Sucralose are approved in more than 100 countries around the globe.

The confidence that consumers and food and drink manufacturers can have in a.m. sweeteners is reflected in their high Acceptable Daily Intake (ADI) values. The ADI represents the safe daily consumption level of an ingredient over a person’s lifetime and is expressed in milligrams per kilogram of body weight. For Aspartame e.g. in the European Union the ADI has been set at 40mg/kg/day. This is the highest value set for any low calorie sweetener. For a person weighing 70 kg, the European ADI is equivalent to the amount of Aspartame which would be used to replace over half a kilo of sugar.

Glycaemic IndexAlthough Sucralose is made initially from sugar, it is not metabolized and dose not release sugar to the body after consumption. Acesulfame-K and Aspartame are not made from sugar and can therefore also not release sugars. A low glycaemic index (GI) diet avoids quick release of carbohydrates such as sugars which can cause sudden spikes in blood glucose levels. Because HYET Sweets High intense sweetener products do not release carbohydrates, replacing sugar with Aspartame, Acesulfame-K or Sucralose can reduce the GI of a product by up to 90%.HYET Sweet High intense sweeteners are fully suitable for diabetics.None of the marketed sweeteners is made of animal origin and is therefore suitable for both vegetarians and vegans.

Tooth friendlyThe HYET Sweet High intense sweeteners are tooth friendly. Using the sweeteners pure or in blends reduces the intake of fermentable carbohydrates- which is a key factor to tooth decay. The sweeteners do not promote the

buildup of plaque or acid which is producing bacteria. Because the HYET Sweet High intense sweeteners are non-cariogenic, they are ideal for confectionary products such as chewing gum and sugar free sweets.

Manufactured to save calories

Significant Calorie and Carbohydrate reduction High Intense sweeteners are mainly used for its properties to reduce calories in common foods and beverages. Within the HYET range of products Acesulfame-K and Sucralose are free of calories. Aspartame has an energy value of

4 kcal per gram (16, 8 kj/g). Only tiny amounts of it can already provide equivalent sweetness as sugar. Thus it can reduce product’s calorie content by up to 99%.

Digested NaturallyFrom the range of HYET Sweet high intense sweeteners products, Aspartame shows a unique property. Acesulfame-K and Sucralose are absorbed and excreted unchanged by the human body. Aspartame is a dipeptide made basically from 2 simple amino acids, L aspartic acid and L phenylalanine. Whereby Phenylalanine is an essential amino acids. These compounds are found in proteins of daily foods, and consequently they are metabolized by the human body in exact the same way as they would be if they came from meat, cheese, fish or any other protein containing source. When Aspartame is consumed it breaks down into aspartic acid, phenylalanine and a small amount of Methanol, analog to that found naturally e.g. pectin containing foods. The normal diet provides much greater quantities of these compounds than that Aspartame does.

PotencyHigh intense sweeteners are significantly powerful in sweetness power than any sugar. The commercial available products range from 40 to 20.000 times as sweet as sugar. Out of this range HYETSweet selected the technically best per forming sweeteners, which represent sweetness power from 200 to 600 (Sugar equivalents) Acesulfame-K and Aspartame are approx. 200 times as sweet as sugar. Sucralose, when used on its own supplies approx. 500 times of the sweetness of sucrose. Sweeteners in blends can provide significant synergy, which can reach ideally up to 40%. Some combinations definitely don’t reach this top results but also may supply 5 – 10% synergy. In general one can say that higher potency is reached at lower concentration. This is true for all sweeteners known. Formulating with HIS in any case needs a fine tuning, to get the highest sensory acceptance. Synergy values and sweetening power data are recommended for using as an indicator when starting formulation work. The final product properties like, pH, typical consumption temperature, viscosity and flavor system have a major impact on the recognizable sweetness and should be considered when the sweetening system is designed.

SolubilityAcesulfame–K and Sucralose are very easily to dissolve in water. At 20°C a solution of up to 25% can be produced relatively quickly. Aspartame can be dissolved in water up to 1% at room temperature. This is influenced mainly by the nature of the dipeptide structure. Aspartame’s isoelectric point is at approx. pH5. Thus, buffering a solution at pH < 4 will help to dissolve Aspartame quickly, and increasing the temperature to e.g. 30°C will allow to dissolve 1,5%. For further details please see graphic.

Best stabilityAs aspartame can be split up during metabolism by human body. It also tends to degrade in liquids. However this is not a spontaneous reaction. Comparable to loss of Vitamin C, it runs slowly but steadily over time. Aspartame is sufficiently stable in liquids for a wide range of products. The stability in liquids can be influenced positively. (Details please see under liquid Application.)

Stability in dry applicationsSucralose, Acesulfame-K and Aspartame are stable in dry and most liquid applications. The shelf life under dry conditions is guaranteed for a minimum of 2 years for Acesulfame-K and Sucralose and 5 years for the European originated Aspartame. For Aspartame temperatures over 110°C are to avoided. As from this point, thermal decomposition occurs.

Liquid applicationsSucralose and Acesulfame-K are proven to be stable in most commercial liquid applications. Aspartame dissolved in water show slowly degradation into its constituents. These are safe and tasteless and do not affect the final product. Key factors influencing the stability of Aspartame are temperature and pH. Optimal stability is reached at pH 4,2. The pH range at which the stability is considered to be acceptable is from pH 2,5 to pH5. Thus most commercial available drinks will fall into this range. Aspartame is applicable for those products.

Heat treatmentHeat treatment in food and beverage manufacturing does not influence significantly the stability of Acesulfame-K and Sucralose. Both sweeteners will not degrade during the known and typical heat treatments. The dipeptide structure of Aspartame will lead to a slight degradation during the process steps. The loss is directly linked to the process conditions and can be influenced by choosing the method.

Stability during storageAnalog to dry application Sucralose and Acesulfame-K are not expected to degrade when stored in liquid. Aspartame degradation is follows approximately 1st order kinetics, comparable to vitamin C degradation. The pH of the product is an important parameter. The closer the pH is to 4,2, the better the stability of Aspartame is. At low temperatures the decomposition is either slowed down or even completely stopped as it is the case in frozen desserts or chilled products like yoghurts. Stability in blends of sweeteners is special area of interest. Due to the synergy generated from using sweeteners of different structure and in individual low concentrations, some sweetness saving strategic mixtures can be used. The degradation of Aspartame will shift over time the blend ratio towards the stable components. For example, a starting ratio of 70% Aspartame and 30% Acesulfame–K will be after a certain period of shift to 60% Aspartame and 40% Acesulfame-K just by the decomposition of the Aspartame. Hover the highest synergy is reached when approx. 60/40 is active. Degradation of Aspartame will make the blend less sweet, but shifting the blend ration towardsthe highest synergy level at the same time will increase the perceived sweetness. Thus this development is buffering the loss effect and can

be used to extend the shelf life or to retain the loss during a certain period at a minimum.

HYET sweet has done numerous tests on this topic. For further information about the stability of Aspartame and Aspartame in blends, please contact the technical support at HYET Sweet.

Table shows that UHT (high temperature applied for a relative short time) is the mildest method. This is in line with the knowledge from saving e.g. vitamins or other heat sensitive ingredients

during a heat treatment step. In general the loss of Aspartame is between 0,5% and approx. 5%. Thus adjusting the dosage to compensate the heat treatment loss is recommended.
