The present technology is generally related to starches and starch blends. More specifically it is related to starch blends that improve the texture and stability of comestibles that incorporate the starch blend.
Starches are used in the food industry to add texture to food products. It is the viscosifying properties of starches that are known to improve the texture of food products. The currently available starches, and particularly the amylose-containing starches, however, tend to gel upon cooking and cooling. Further, sauces and gravies, soups, creamers, salad dressings, and other liquid compositions prepared with amylose-containing starches become unstable upon freezing and thawing. As a result, there remains a need in the food industry for a starch that does not gel upon cooking and cooling and/or that is stable upon freezing and thawing.
In one aspect, a starch blend is provided that includes an unmodified amylose-containing starch and a non-chemically inhibited starch or non-chemically modified starch. Also disclosed herein are edible compositions comprising one or more starch blend described herein. Such starch blends address the gelling and/or stability problems associated with using the currently available starches.
These ranges may include 40-85% (w/w), 40-80% (w/w), 50-70% (w/w), 55-65% (w/w), or 50% (w/w) of the unmodified amylose-containing starch and 15-20% (w/w), 20-60% (w/w), 30-50% (w/w), 35-45% (w/w), or 50% (w/w) of the non-chemically inhibited or non-chemically modified starch. In some embodiments, the starch blends described herein are clean label starch blends.
One or more starch blend described herein has, upon cooking in water, a high viscosity after one or more, two or more, three or more, four or more, or five or more freeze-thaw cycles. One or more starch blend described herein has, upon cooking in water, a high viscosity after three or more freeze-thaw cycles. One or more starch blend described herein is useful in a variety of food and beverage compositions, particularly frozen sauces and gravies. Yet a further embodiment is directed to a method of preparing a composition comprising one or more viscosifying agent comprising one or more starch blend described herein and one or more other viscosifying agent, wherein the other viscosifying agent is at least partially replaced or replaced with 90% or less of one or more starch blend described herein.
In another aspect, a composition comprises 90-97% (w/w) of a fluid; 3-8% (w/w) of an unmodified amylose containing starch; and 0.5-2% (w/w) of a non-chemically inhibited starch or non-chemically modified starch. In some embodiments, the fluid is a milk product or water.
Various embodiments are described hereinafter. It should be noted that the specific embodiments are not intended as an exhaustive description or as a limitation to the broader aspects discussed herein. One aspect described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced with any other embodiment(s).
The following terms are defined for clarity. Terms not defined should be accorded their ordinary meaning as used in the art and commonly understood by one of ordinary skill in the art.
The singular terms “a”, “an”, and “the” include the plural reference unless the context clearly indicates otherwise.
The term “amylose-containing” refers to a starch with at least 10% to less than 50% amylose (w/w) based upon the starch.

The term “non-chemical inhibition”, “non-chemically inhibited”, or “non-chemically modified” refers to a starch that functions as a chemically inhibited starch without being chemically modified.
The term “highly inhibited” refers to a starch that is inhibited to such a degree that it swells to a limited extent and shows a continuing rise in viscosity without attaining a peak.
The term “moderately inhibited” refers to a starch that is inhibited to such a degree that it exhibits a lower peak viscosity and a lower percentage breakdown in viscosity compared to the same starch that is not inhibited.
The term “native” refers to an unmodified starch as extracted from a plant source such as cereals, tubers, roots, legumes and fruits.
The term “starch” refers to starch and flour.
The term “unmodified” refers to a native starch or a native starch that has been physically modified. The term “unmodified” excludes a starch or flour that has been chemically or enzymatically modified.

In another aspect, the present invention is directed to starch blends of at least an instant starch or flour with a cook-up starch or flour to improve the texture stability of food systems and more particularly to impeding gelation. The blends of the instant starch or flour, more particularly a drum-dried amylose containing tapioca starch or flour, with the cook-up starch or flour, more particularly a thermally inhibited amylose containing tapioca starch, may increase the stability of a comestible using the cook-up starch or flour, more particularly a thermally inhibited amylose-containing tapioca starch or flour, by inhibiting gelation. The starch blends may be used to alter the rheology of comestibles, and more particularly to reduce shear thinning. The starch blends, more particularly a drum-dried thermally inhibited waxy corn, a drum-dried waxy corn, or a spray-dried waxy corn, with a cook-up starch or flour, more particularly a thermally inhibited waxy corn, can alter the flow properties of comestibles by increasing the flow behavior index, n, (i.e. less shear thinning or maintaining high viscosity at high shear rate).
In making food products, i.e. comestibles, such as frozen meals, refrigerated dairy and retorted soups, a starch or flour is added to improve the products rheological properties, textural properties, and stability of the final frozen or refrigerated food product. It has unexpectedly been found that the combination of a drum-dried amylose containing tapioca starch with thermally inhibited amylose containing tapioca starch provides improved refrigerator stability (reducing gelling) over thermally inhibited or native amylose containing tapioca starch alone.
In some embodiments, a composition is provided, the composition including 90-97% (w/w) of a fluid, 3-8% (w/w) of an inhibited amylose containing starch or flour; and 0.5-2% (w/w) of a non-inhibited starch or flour. The fluid may include a milk product or water. The inhibited amylose containing starch or flour may be any of those as described above, including, but not limited to a thermally inhibited tapioca starch or a thermally inhibited waxy corn starch. The non-inhibited amylose containing starch may be any of those as described above, including, but not limited to a drum-dried tapioca starch or flour, a drum-dried pre-gelled tapioca starch or flour, a spray-dried pre-gelled corn starch or flour, a drum-dried pre-gelled waxy corn starch or flour, or a spray-dried pre-gelled waxy corn starch or flour.
According to various embodiments, the composition may be a smoother texture after cooling to approximately 2-7° C. for one week, compared to a composition without the non-inhibited modified starch.
The present invention, thus generally described, will be understood more readily by reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention.
The following examples are presented to further illustrate and explain the present invention and should not be taken as limiting in any regard. All percentages used are on a weight/weight basis.

This mixture is then premixed in a Thermomix (TM5-4) for five minutes at room temperature at speed 2. The temperature was then adjusted to 90.6° C. and held for 25 minutes. The mixture was subsequently dispensed into jars and stored under refrigeration at approximately 2-7° C.
The samples were visually evaluated over time and the formulation containing the starch blend comprising S9 and S10 exhibited improved stability at both 24 hours and 6 weeks aging. The use of S9 alone resulted in a very firm gel, which on stirring remained very lumpy. The starch blend comprising S9 and S10, however, provided a soft-set product having a smooth texture upon stirring.
The same starch combination as in Example 5 was also tested in a simple starch/flour and water system. In starch and water, improved stability was also observed with the addition of a starch blend comprising S9 and S10.
A starch blend comprising S9 and S10 provided a food composition with significantly improved texture—no gelling or syneresis, and no graininess. This starch blend may be used to produce a sauce, gravy or soup that has the appearance and eating quality that consumers desire after being stored under refrigeration (e.g. about 2-7° C.).
This example illustrates the improvement of pudding stability using a starch blend comprising S9 and S10. As demonstrated in
This example demonstrates how a starch blend, specifically a drum-dried waxy corn, with a cook-up starch, specifically thermally inhibited waxy corn, can be used to change rheology properties of a food system. Addition of S13 can reduce yield stress (
Power law model (Eq. 1: σ=Kγn or η=Kγn-1) was used to describe flowing property of materials, where σ [Pa] is shear stress, η [Pa·s] is the apparent viscosity, γ [1/s] is shear rate, K [Pa·s] is the flow consistency index, and n is the flow behavior index. For shear thinning material, the flow behavior index is typically a value between 0 and 1, where a higher value indicates less shear thinning. As illustrated in Table 10, addition of S13 led to higher flow behavior index, suggesting less shear thinning.
This example demonstrates that the starch blends described herein, specifically a drum-dried waxy corn starch or a spray-dried waxy corn starch, with a cook-up starch, specifically a thermally-inhibited waxy corn, can be used to change the rheology property of food systems. Addition of S14 or S11 has the same effects as S13 and can reduce yield stress (
