Help with a beverage formulation.....

Hello.
Before I get flamed, I realize this is not a cosmetic chemistry question but I thought I may be able to find some help here.
I create all natural, healthy drink shake powders.
With my latest project, I am trying to create "no added sugar" version of a popular dairy drink.
My starting point is to re-create what is currently on the market, containing sugar and then reformulate without the sugar.
I have the formula very close but the current products provide a cold sensation on the tongue that I can't seen to replicate.
The ingredients seem pretty basic; sugar, natural flavor, color, maltodextrin, carageen, beta carotene, citric acid, salt and a vitamin blend.

I originally figured the salt or citric acid would provide that sensation, but I can not replicate in my trials.

Any thoughts or help would be much appreciated.
Jason

    The cool effect may be provided by one of the ingredients present under the disguise of flavor.

    There are a number of materials that will achieve this but, unless you are a reasonably sized manufacturer, these may not be available to you.

    It is a specialised area and if you want to pursue this, I suggest that you contact a flavor house/manufacturer
  • I was thinking that may be the case since the flavor components are not required to be detailed.
    However, I have been working with 4 different flavor houses and tried each of their flavor products. I do not have that effect with any of them.

    Have you requested a cooling agent to be included or suggested to them that they do this? There are lots of potential materials available.
  • Is the shake powder meant to be added in situ by the consumer?

    Could you compensate with the cooling effect provided by erythritol and/or xylitol as they dissolve in water?
  • Johnb point me in the direction with an example or two of what materials you were thinking. I'd like to research and be informed before I request that to the flavor labs

    Elise I can def use erythritol or Xylitol. That is a great idea since I plan to be sugar free in the end. I will experiment with those to see how that works.

    I am unable to give examples of cooling materials as I have no idea as to the detail of the product you wish to make. Look at http://leffingwell.com/cooler_than_menthol.htm for a detailed account of physiological cooling agents. Your flavour labs should be fully cogniscent with the materials available

    Regarding  the sugar alcohols (erythritol/xylitol/sorbitol/etc). These materials do have a negative heat of solution and will physically reduce the temperature of water during dissolution - this is taken advantage of with such things as sugar free candies where the cooling effect is used as a marketing ploy. Whether this temperature reduction would be noticeable in the large dilution factor involved in mixing into a beverage remains to be seen. There are a couple of things to be aware of using sugar alcohols:
    1. the cooling is very short lived and only occurs during the dissolution. That is to say that it is pointless marketing as a predissolved (liquid) product.
    2. Sugar alcohols have a laxative effect. This is more pronounced in some than others but it can give some very unwanted side effects.
  • I was concerned with the laxative effect of the SAs. I had some xylitol around and tried that . It didnt compare to the product I am evaluating. I have downloaded that doc for review. Thanks

    @johnb the physical cooling effect of sugar alcohols is short, but they definitely give a cool sensation in solution too 

    while I was working on an own-brand knock off of Listerine mouthwash a few years back, I found sorbitol (added as a 70% solution) greatly enhanced the product's flavour and the cooling sensation, and was part of the reason the product had such a 'powerful' taste

    Bill, I was thinking more of the low concentration in a beverage product more than a strong dental product.
