Low-acetyl gellan gum blends

BACKGROUND OF THE INVENTION
The use of gellan gum to form gels in the presence of mono- or divalent cations is known. A particular utility of these gels is in the formation of gelled food products. Several publications have taught the use of gellan gum in such applications e.g., Sanderson et al., Gums and Stabilizers for the Food Industry 2, G. O. Phillips et al. (ed.), 201-210, Pergamon Press (1984); Sanderson et al., "Gellan Gum", Food Technology, 63-70, April 1983; and Japanese patent application 88051/1984, May 21, 1984. These publications suggest blending gellan gum with other hydrocolloids for the purpose of modifying gel texture. Example 7 of the Japanese application teaches an extruded noodle using gellan gum, locust bean gum, and xanthan gum in a 2:1:1 ratio at a total concentration of 0.8 wt.%.
Modification of the texture of xanthan/lbg gels resulting from adding a third component such as guar, agar, or carrageenan is described in P. Kovacs, Food Technology, Vol. 27, No. 3, pp. 26-30 (1973). The third component imparts some of its textural characteristics to the xanthan/lbg gel.
SUMMARY OF THE INVENTION
It has now been found that blends of low-acetyl gellan gum+xanthan gum/galactomannan in the ratios by weight of 95:5 to 5:95 wherein the ratios of xanthan gum to galactomannan range from 4:1 to 1:4 are particularly useful in gelled food applications.
DETAILED DESCRIPTION
Gellan gum refers to the extracellular polysaccharide obtained by the aerobic fermentation of the microorganism, Pseudomonas elodea, in a suitable nutrient medium. Various forms of gellan gum have been described. (U.S. Pat. No. 4,503,084, Baird et al.) e.g., native, deacetylated, deacetylated clarified, partially deacetylated, and partially deacetylated clarified. As used hereinafter, "gellan" gum shall refer only to low acetyl (LA) gellan gum, i.e., a gellan gum wherein the acetyl level is 0.3-0% (wt.).
Xanthan gum is an extracellular polysaccharide produced during fermentation of carbohydrates by Xanthamonas campestris and other bacteria of the genus Xanthomonas. The gum is manufactured in industrial scale and is used widely as, for example, a thickener in foods.
Cassia gum, like lbg, is a pod extract, derived from Cassia occidentalis or fistula.
The following plant extracts are described in "Polysaccharides in Food", Blanshard et al., 232-235, Buttersworth & Co., Ltd., 1979.
Locust bean gum (lbg) is an extract of the locust bean or carob, Ceratonia siligua. It is commercially available and used as a stabilizer in foods such as ice cream, sausages, and cheese. Chemically, lbg is a galactomannan.
Konjak (or konjac) gum is a glucomannan extracted from the plant Amorphophallus konjac.
Tara gum is a vegetable gum derived from the seed of the legume Cesalpinia spinosa.
The texture profile of a gel can be evaluated in terms of four parameters: modulus, hardness, brittleness, and elasticity. These are standard gel properties that are determined, for example, on an Instron 4201 Universal Testing Machine, which compresses the sample to about 1/4 of its original height two times in succession. The sample is compressed twice so that the amount of structure breakdown can be determined.
Modulus is the first parameter that is determined when testing a sample. The modulus is the initial slope of the force-deformation curve. This is a measure of how the sample behaves when compressed a small amount. The modulus usually correlates very closely with a sensory perception of the sample's firmness. Modulus is expressed in units of force per unit area (pounds per square inch or Newton's per square centimeter).
Hardness is defined as the maximum force that occurs at any time during the first compression cycle. It may occur when the gel initially breaks, or it may occur later in the test as the sample is flattened and deformed. In most cases, the hardness is correlated to the rupture strength of the material. It is expressed in units of force (pounds or Newtons).
Brittleness is defined as the first significant drop in the force-deformation curve during the first compression cycle. This is the point of first fracture or cracking of the sample. A gel that fractures very early in the compression cycle is considered to be more brittle or fragile than one that breaks later. Brittleness is measured as the % strain required to break the gel. As the number gets smaller, it indicates a more brittle gel at a lower strain level.
Following the first compression cycle, the force is removed from the sample as the Instron crosshead moves back up.
A measure of the sample's elasticity is taken as the second compression cycle is begun. By noting where the force begins to increase during this second compression cycle, a measure of the sample height may be obtained. If the sample returned to its original height, the elasticity would be 100%. The elasticity is a measure of how much the original structure of the sample was broken down by the initial compression. In sensory terms, it can be thought of as how "rubbery" the sample will feel in the mouth. The units are dimensionless and expressed as a %.
It has been found that varying the ratio of xanthan:galactomannan has an effect on three of these parameters: hardness, modulus, and brittleness. But, surprisingly and unexpectedly, although the addition of xanthan/galactomannan increases the elasticity of gellan gels, varying the ratio of xanthan to galactomannan has little effect on elasticity. Thus, this three-component blend allows the practioner to prepare a broad range of gelled food products with reduced brittleness and greater elasticity relative to LA gellan gum along and a controlled degree of hardness and modulus.
The blend is particularly useful in pet foods, i.e., gelled or restructured meat products; confectionery jellies; jams; low calorie jams and jellies; gelled milk desserts; water-based desserts; aspics; pie fillings; vegetable, fruit, or fish gels; syrups; or toppings. Depending on the particular food, use levels of the blends can range from 0.1 to 1.5%, based on total product weight.
The gum blends of this invention comprise gellan:(xanthan/galactomannan) in the ratios by weight 95:5 to 5:95 wherein the ratio xanthan/galactomannan ranges from 4:1 to 1:4 and the galactomannan is locust bean or tara gum with the proviso that when the galactomannan is lbg the ratio is not 2:1:1. The invention also comprises aqueous gels comprising 0.1 to 1.5% (wt.) of the gum blends.
In place of lbg or tara, either Cassia gum or konjak gum may be used on a weight-for-weight basis. The use of konjak produces a greater loss in hardness and a smaller decrease in brittleness relative to lbg.
The invention also comprises a gelled food product comprising a matrix having one or more food ingredients dispersed therein, said food ingredients being selected from the group consisting of vegetable, fruit, meat, fish, sugar, milk, and mixtures thereof, said matrix comprising 0.1 to 1.5%, based on total product weight, of a blend of gellan:(xanthan/galactomannan) in the ratios by weight 95:5 to 5:95 wherein the ratio xanthan/galactomannan ranges from 4:1 to 1:4 and the galactomannan is locust bean or tara gum.
The gelled food products are restructured meat; confectionary jellies; jams; low caloric jams and jellies; gelled milk desserts; water-based desserts; aspics; pie fillings; vegetable, fruit, or fish gels; syrups or toppings.
The gum blends of Table I are within the scope of this invention.

The invention is further defined by reference to the following examples, which are intended to be illustrative and not limiting.

EXAMPLE 1
Evaluation of Gellan:Xanthan:lbg Blends
Various ratios of xanthan/lbg (95:5, 80:20, 70:30, 30:70, 20:80, 5:95) were evaluated in combination with gellan gum. As shown in Table 1--1, each blend ratio affects the texture of gellan gum gels in a way that is determined, for the most part, by the predominant hydrocolloid in the xanthan/lbg blend. For example, the addition of 0.25% xanthan or 0.25% lbg alone has virtually no effect on the hardness value of a 0.25% gellan gum gel (1.92 lbs and 2.00 lbs, respectively). The addition of 0.25% xanthan/lbg (4:1 to 1:4), taking advantage of their combined effect, increases the hardness value to between 2.52 and 3.12 lbs. Shifting the ratio of the xanthan/lbg blend outside the range 4:1 to 1:4 so that one or the other hydrocolloid predominates gives a gel whose hardness value shifts towards what the value would be if the predominant hydrocolloid was used, alone, in combination with gellan gum.
The data for the modulus and brittleness parameters show that gellan gum gels, in combination with xanthan/lbg (varying ratios), exhibit the same trends seen with the hardness parameter, i.e., the extent of texture modification is dependent on the ratio of the added xanthan/lbg blend.
However, while the addition of xanthan/lbg to gellan gum increases gel elasticity, varying the ratios of the xanthan/lbg blend does not significantly change the elasticity value.

Canned Pet Food
A series of experiments were run to compare gellan gum and gellan-xanthan/locust bean gum blends to one another at different ratios and use levels in a canned pet food product.
Procedure
Two hundred and seventy five grams of ground pet food meat and offal were weighed into a No. 1 Eastern can. A preweighed amount of gum in 25 mls of water was then added, and the can sealed and autoclaved at 250.degree. F. (121.degree. C.) for 80 minutes. The cans were carefully removed from the pressurized container, gently agitated for 1 minute, allowed to cool undisturbed, and left for a minimum of 24 hours before opening.
The following gums were examined:

Results
Results showed that by increasing the ratio of xanthan/lbg to gellan a more elastic, less brittle gel was formed around the meat matrix; i.e. 6 was less brittle than 4 and 5, and 1 was less brittle that 2 and 3.
Also, it is found that increasing the concentration of the blend from 0.4% to 0.6% provided a firmer, less brittle gel; i.e., 3 was firmer than 4. In all cases, it was found that the blends gave less brittle and more elastic gels than No. 7, the control sample, which produced a very brittle gel.
