Definitions

  • the present invention relates to food concentrates.
  • Food concentrates like soup, gravy and sauce concentrates are food products designed to provide a for example ready-to- eat soup, gravy or sauce upon dilution in water and usually heating.
  • Starch is widely used in food products as a thickening agent. In the presence of sufficient water and when the temperature is high enough (usually more than 60°C) the starch granules start to swell. This process, also referred to as gelatinisation, is usually characterised by the loss of the crystalline structure (order-disorder transition) that can be observed by several techniques such as X-ray diffraction, Differential Scanning Calorimetry (DSC) (gelatinisation endothermic peak), and microscopy (loss of birefringence and granule swelling).
  • DSC Differential Scanning Calorimetry
  • the native starches (i.e. unmodified) of different botanical sources differ in their appearance (granule form) and functional properties (e.g. pasting, viscosity). Most of the common starches are readily and unequivocally identifiable under a polarizing microscope, using the criteria of granule size and shape, form and positions (centric or eccentric) of the hilum (botanical centre of the granule) and brilliance of the
  • DSC Scanning Calorimetry
  • the second standard method measures the increase in viscosity is known in the art as a "pasting" curve. It allows to distinguish - inter alia - starches that thicken relatively fast from so called delayed swelling starches. Pasting curves are routinely measured by a Rapid Visco Analyser (RVA) (Biliaderis, C.G. (2009). Chapter 8 - Structural Transitions and Related Physical Properties of Starch. In: Starch (Third Edition) Food Science and Technology, ed. J.BeMiller and R.Whistler San Diego: Academic Press, 293-372).
  • RVA Rapid Visco Analyser
  • An RVA is a rotational viscometer that continuously records the viscosity of a sample under conditions of controlled temperature and shear which can be used to measure the increase in viscosity and to provide an assessment of starch 'pasting'.
  • WO 2005/074717 A1 discloses concentrates with waxy corn starch or "heat moisture treated starch" of an unidentified type.
  • GB 2 030 438 A discloses heat moisture treated (HMT) starches like HMT potato starch.
  • US 5008 124 A discloses dry mixes with non-gelatinised starch.
  • a food concentrate will have a relatively high amount of starch depending on the dilution factor it has been designed for and the desired viscosity of the ready-to-eat product.
  • a food concentrate designed to be diluted 10 times to prepare the ready-to-eat product will have a 10 times higher amount of starch than in the ready-to-eat products.
  • These high amounts of starch in the concentrate may lead to lumping problems when the consumer tries to dilute the concentrates.
  • Starches have been modified to decrease the lumping problem in dry or even pasty concentrates.
  • WO 2014/053287 and WO 2014/053288 disclose as most preferred starch native corn and heat moisture treated (HMT) potato starch for low lumping. It has been reported that using the proper dilution protocol low or even no lumping may be obtained with native corn starch and HMT potato starch.
  • EP 1602289 and WO 2004/049822 disclose the use of a non-gelatinised heat moisture treated potato starch in a shelf stable pasty concentrated composition in the presence of relatively high amounts of sorbitol.
  • sorbitol is a not desirable ingredient for a gravy, soup or sauce.
  • a small subset of users have reported that concentrates with non-gelatinised heat moisture treated potato starch show
  • WO 2014/009079 discloses gelled concentrates with starches with a low gelatinization temperature.

  • the Ref RVA-solution is representative of a typical salt and sugar concentrations in the ready-to eat product.
  • RVA standard analysis (STD1 ) test conditions available in the standard equipment software package (Thermocline for Windows, TCW. Newport Scientific) can be described as:
  • the amount of starch to be added to the Ref RVA-solution to achieve ViscRef can be easily adjusted by a person skilled in the art, for example by testing a range of amounts of starch added to the Ref RVA-Solution and obtaining ViscRef between 180-320 cP.
  • the suitable amount of starch for the RVA analysis is preferably 0.8 to 2 g.
  • Typical ranges of the starch amounts to be tested are: o Sago starch native and modified: 0.9-1.7 g
  • the characteristic delayed swelling of the starch can also be measured in the concentrate.
  • a suitable amount of the concentrate e.g. 3-5g
  • a suitable amount of starch e.g. 0.8-2g
  • the amount of concentrate to be added to 25g of water will depend on the type of starch and amount of starch present in the concentrate and can be easily adjusted by a person skilled in the art, for example by testing a range of amounts of concentrate added to 25g of water.
  • the characteristic delayed swelling of the starch in a food concentrate can be measured using a method comprising the following steps of:
  • T1 and T2 are as defined supra. Standardised wet lumping test
  • lumping of a concentrate according to the invention is preferably measured in the test below.
  • the chosen test conditions favour the formation of lumps, i.e. adding the gelled concentrate in boiling water and with very mild stirring. This will allow to provide preferred food concentrates according to the invention which are more robust in use, even when consumers deviate from the instructions of use.
  • a kitchen food preparation machine (Kenwood Cooking chef major KM070 series or similar), with temperature control with major sized Anchor Flexi beater stirrer attachment or similar.
  • the % of material undissolved can be higher than 100% in cases in which the amount of material retained in the sieve is higher than the initial amount of concentrate (e.g. 25g concentrate is tested and the amount weighed in the sieve is 28 g) . That is because the starch lumps also absorb water during cooking and that would be reflected in the amount retained in the sieve.
  • the preferred non-gelatinised starch used in the invention shows a surprising decrease in lumping compared to the same concentrate with the same amount of native starch of the same botanical source. Since the lumping test overestimates the lumping, it is expected that in real use including the addition of the concentrate to water at lower temperatures and/or e.g. intensive stirring with a hand whisk, as can be expected from some consumers, would lead to far lower absolute amount of lumps. However, a difference between preferred starches that are part of the invention and native starches of the same botanical source that are not part of the invention would still be observed.

  • the viscosity of the ready-to-eat product the product is prepared under mild conditions so no lumps are present (i.e. recommended water temperature and suitable stirring). As some starches will take more time to reach full viscosity, the same experiment is repeated with stirring and heating for 5 respectively 10 minutes and the highest viscosity measured is noted.

  • Example 1 of WO 2004/049822 discloses a liquid fluid thickener composition with 32% non-gelatinised starch and 43.4% sorbitol as shown below. As sorbitol is not acceptable for many consumers, an attempt was made to produce a thickener according to example 1 of WO 2004/049822 but without sorbitol.
