Abstract

Edible materials contain a thickened or gelled phase comprising a mixture or a reaction product of at least one carrageenan and at least one glucomannan. The gelled phase may be either a thermo-irreversible gel or a thermo-reversible gel and the pH of the edible material is below 8. The glucomannan may be derived from plants of the Iris, Aloe or Amorphophallus genus, or from yams. The gels may be used in meat-in-jelly products or dessert gels.

Description

SPECIFICATION Edible materials This invention relates to edible materials and, especially to a gelling system for use in the preparation of gelled or thickened food products.
A varitety of gelling, binding and thickening agents, are used in the food and confectionary industries to impart desired textural and aesthetic qualities to foodstuffs including, for example, meat loaves, canned pie fillings, petfoods, ice cream, yoghurts, formed fruit pieces etc.
It is known that glucomannans such as those extracted from theAmorphophallus sp. for example A. konjac, when treated with alkalis react to form a very tough thermo-irreversible gel. The pH required forthis gelling reaction is at least 9 and a pH greatly in excess of 9 is frequently used. It is widely believed that calcium ions are also essential for this process.
It is also known that gels can be formed using for example pectins and seaweed extracts such as alginates and agar. Alginates and pectates normally form thermo-irreversible gels in the presence of divalent ions. The reaction rate and strength of these thermo-irreversible gels increases with decreasing pH. By control of divalent ion availability, which is itself pH dependent, a thermo-reversible gel can be produced using pectates.
Certain forms of carrageenan, especially kappa and iota carrageenans, but not lambda-carrageenan, can also be used to form gels. These gels are thermo-reversible and although they can form gels at low pH, they are readily hydrolysed if heated at temperatures in excess of 100 degrees Centigrade at pH values below 7. The extent of hydrolysis is very pH dependent increasing sharply with decreasing pH.
It is further known that there is an interaction between kappa carrageenan and locust bean gum (carob gum) which results in enhanced viscosity development and gelation properties. A mixture of carob gum and carrageenan is widely used to provide viscous gravies, in for example canned pie fillings, and thermo-reversible gels in for example canned petfoods, brawns and table jellies. An additional advantage of the interaction is that the carrageenan gel texture is modified to provide additional desirable characteristics such as reduced brittleness and increased softness.
In contrast to the thermo-irreversible gels of calcium alginate and calcium polypectate, car rageenan/carob gum mixtures cannot be used to provide structure in formed products which are to be subjected to heating above the melting point of the gel system. Thus, for example the car rageenan/carob gum gelling system cannot form the basis of a formed chunk in a product which requires to be heated above the melting point of the gelling system since the chunk disintegrates on melting of the gel.
Until now, carob gum has been thought to be unique in its ability to maximise the gelling or thickening properties of carrageenan. Although, like carob gum, guar gum and tara gum are galactomannans, their interaction with carrageenans is considerably less than that of carbo gum and these polysaccharides are of little use in this context.
It has been proposed in Japanese published patent application 1976/52648 to produce a gelled seaweed food by blending dissolved or colloidised seaweed with dissolved Devils Tongue material (a glucomannan containing material). The blend is caused to gel by the normal method for gelling glucomannan, namely, the addition of alkali. The gel is a thermo-irreversible gel.
The presence of high alkalinity in food products is generally undesirable and accordingly the presence of a thickened or gelled phase which has been produced at high pH in most food products is very undesirable.
This invention is based on the observation that in complete contrast to the teaching of the prior art, glucomannans can be caused to form thermoirreversible gels at a pH not higher than 8 if they are heated together with a carrageenan at a temperature above 100"C for a sufficient period.
Moreover it has been observed that in the presence of certain foodstuffs, for example meats, and proteinaceous materials of both vegetable and animal origin, the same systems under the same conditions forthermo-reversible gels. It has further been observed that at pH values below 5.0, the glucomannan/carrageenan system always produces a thermo-reversible gel. The thermo-reversible gels can be formed simply by incorporating a mixture of powdered glucomannan and carrageenan in hot water, or can be formed in complex systems such as sterilised canned' meat products. Glucomannan/carrageenan combinations are not only stable to heat sterilisation but are also less sensitive to low pH conditions during heat treatment than corresponding carob gum/carrageenan solutions. This property is of especial value in foods which require heating in the presence of acid in low concentrations.
This invention therefore provides an edible material having a pH not higher than 8 comprising a gelled or thickened aqueous phase containing a mixture or a reaction product of at least one glucomannan and at least one carrageenan.
Either or both the glucomannan or carrageenan may be used in a crude form (i.e. as a natural product containing the polysaccharide material), as the refined polysaccharide, or in an intermediary form.
The product of the invention is an edible material having a pH not higher than 8, which is structured, or shaped, or bound, substantially by a gel' matrix produced from a mixture of glucomannan and carrageenan in the aqueous phase.
The edible material of the invention may be any foodstuff or confectionery in which it is desired to have a gelled or thickened phase. As athermo- irreversible gel the edible material may comprise, for example a gelled chunk which, with the addition of flavouring and colourings etc. may be used as a meat analogue and in this form the material' may have a texture very similar to cooked lung. As a thermo-reversible gel the edible material' may be for example a' meat-in-jelly petfood or at very acid pH down to about say 3 a thermo-reversible gel' may be present in gelled desserts and confectionery, espe cially fruit based products in which the fruit acids considerably lower the pH.
Any carrageenan or carrageenan-type polysac charide, for example, furcellaran is suitable. The car rageenan may be used in a crude form (e.g. washed seaweed) or in an alkaline modified form or in the form of the conventional carrageenan extracts of commerce. The carrageenan may be any form of carrageenan such as lambda, iota, kappa car rageenan or any mixture, although the preferred car rageenan types are those containing some kappa carrageenan.
The glucomannans may be used in a purified form or in a crude form. The crude form may merely be the ground source of glucomannan without further treatment. Glucomannans are present in a variety of plants. For example they are found in yams, such as Elephant Yam, in seeds such as the endosperm of Iris ochroleuca and Iris sibirica and in leaves such as those of the plantAloe vera. The preferred glucomannans are found in the corms of the Amor phophallus genus and in particularA. riviera (syn.A.
konjac),A. campanulatus, A. oncophyllous and A.
varialbis.
The preferred ratio of glucomannan to carrageenan is in the range 20:1 to 1:20 especially 1:10 to 10:1, and the preferred concentration of the combined mixture in the aqueous phase is 0.01% to 5%.
The mechanism of the thermo-irreversible gel formation is not fully understood but the degree of gel formation appears to be governed by pH, the glucomannan and carrageenan contents and the heat input. The gelling system must be heated to a temperature of at least 100"C and the particular time needed for gel formation depends basically on the temperature. Under the heating conditions normally applied for heat sterilisation, for example, 130"C for 50 to 60 minutes, a thermo-irreversible gel will nor mally be formed with total carrageenan and glucomannan content as low as 1% when the pH is between 6 and 8. The amount of heat required seems to depend on both pH and gum content but appears to be at a minimum at pH 7 when the concentration of glucomannan and carrageenan is high.
The following Examples illustrate the invention. In the Examples the carrageenans were commercially available samples of the type specified and the Amorphophallus sp. extract contains approximately 90% glucomannan.
EXAMPLES 1. Thermo-reversible gels.
A petfood product was prepared to the following recipe: INGREDIENT by weight "Meats" "Gravy"
{ bffal Meats 40 Fibrous Muscle Meat 16 Hydrated T.V.P. 10 Condensed Whey 3
{ Dye Solutions 0.7 Water 29.09 Potassium Chloride 0.5 Kappa-carrageenan 0.16 Carob gum (Industrial Grade) 0.55 100.00 The gravy was prepared by mixing all the ingredients at room temperature using a high shear stirrer. Sufficient alkali was added to the gravy in order to' maintain a final product pH of 6.2.The gravy was then added to the coarsely chopped "meats" and the product was filled into' metal cans, which were sealed and heat sterilised in a pressure cooker @ 1300C for 60' minutes after which time the cans were immersed in cold water for half an hour. The product was examined after 1 day.
A similar product was prepared but instead of the 0.16% carrageenan and 0.55% carob gum added to the gravy, 0.11% carrageenan and 0.55% glucomannan extracted frómAmorphophallus sp. was used.
Upon examination the products were assessed to be similar in appearance, taste and firmness. The product containing glucomannan/carrageenan was rated astougherto cut than the control containing carob gum/carrageenan even though the carrageenan level was lower.
The pH of both products was 6.2.
Both gels were thermo-reversible each' melting at 75"C and setting at 42"C and 52"C, respectively.
EXAMPLE 2 This example demonstrates the greater stability of glucomannan/carrageenan solutions to heating at low pH.
The process of Example 1 was repeated using the following petfood recipe.

The control product containing carob gum barely supported its own weight and consisted of meats surrounded by low areas of very weak gel slurry and a large quantity of free watery liquid. This is typical of the degradation of this gelling system subjected to high temperatures at relatively low pH.
In contrast the product containing glucomannan was an integral solid meat and jelly pack, self sup porting and containing areas of clear, soft, tough gel without syneresis.
EXAMPLE 3 This Example demonstrates the preparation of a "formed" solid which is stable to heat in a thermo irreversible structure using carrageenan/glucoman nan.
A 6.8 pH buffer solution was prepared using 0.4 %NaH2PO4 2H2O 0.44% Na2HPO4 0.2 %KCI
7 In distilled water 2 parts of kappa carrageenan and 5 parts ofAmorphophallus sp. extract were dispersed in 1000 parts of the buffer solution and heated to the boil with stirring.
The dispersion was heated in an autoclave at 1300C for 50 minutes. After removal from the autoclave the resulting firm, very tough, solid was cut into chunks. The chunks exhibited remarkable resistance to shearing forces and had a texture similar to cooked lung. With the addition of flavourings and colourings the chunks make an excellent meat analogue.
The chunks were heat sterilised in water in sealed cans at 130 for 1 hour. The chunks retained their separate identity demonstrating thermoirreversibility of the gel.
EXAMPLE 4 This example demonstrates the use of different carrageenans.
(a) Use of Iota carrageenan The process of example 1 was repeated using the following recipe: CONTROL TEST PRODUCT PRODUCT INGREDIENT %byweight %byweight Offal meats 37 37 Fibrous meat 7 7 Hydrated T.V.P. 26 26 Dye solutions 1.5 1.5 Water 27.4 27.0 Sodium Chloride 0.4 0.4 Calcium Hydroxide 0.1 0.1 lota carrageenan 0.6 0.6 Amorphophallus sp. extract - 0.4 pH 6.1 6.3 The control product containing no glucomannan was barely integral just supporting its own weight.
The pack readily broke down under slight pressure to reveal glossy meats in a viscous gravy. There were small areas of a very weak paste-like gel.
In contrast, the product containing the glucoman nan was integral easily supporting its own weight.
This pack had significant areas of an elastic clear glossy gel.
(b) Use ofLambda Carrageenan The process of example 1 was repeated except that: In the control product the carrageenan and carob gum were replaced by 0.5% Lambda carrageenan and the difference was corrected for by adjustment of the water content. The pH of the product was 6.6.
In the test product the carrageenan and carob gum were replaced by 0.5% Lambda carrageenan and 0.4 /Amophophallus sp. extract. Again the recipe was corrected by adjustment of water content. The pH of the product was 6.8.
The control was a non-self supporting meat in gravy product. The gravy was viscous, glossy and clear.
The product containing the giucomannan was firmer and more resistant to rupture and had some areas of clear gel.
EXAMPLE 5 This example demonstrates the use of different types of glucomannan source.
Example 1 was repeated with the carrageenan and carob gum replaced by the following ingredients: In product A, Amorphophallus oncophyllus extract (0.31%) and kappa carrageenan (0.32%) were used (pH 6.8).
In product B, the process and recipe of product A was repeated by replacing the 0.31%A. oncophyllus extract by 0.25%A. riviera extract (pH 6.7).
In product C, the process and recipe of product A.
was repeated but replacing the 0.31%A. oncophyllus extract by 0.31% glucomannan from Indonesian Amorphophallus sp. extract prepared by the process described in Japanese Published Patent application 1979/49346 (pH 6.8).
Examination of the finished products after one day showed that all three were virtually identical being integral solid meat and jelly packs, self supporting and containing areas of clear, soft, tough gel without syneresis.
EXAMPLE 6 This example demonstrates the interaction between glucomannan and carrageenan to product thermo-irreversible gels under different pH conditions.
1. Buffer solutions at pH values of 5.5, 6.5, and 7.0 were prepared to the following formulation: pH mg Na2HPO4 mg NaH2PO4 5.5 205 4795 6.5 1615 3385 7.0 3090 1910 Each of the above dry salt mixtures was dissolved in 500 ml of distilled water.
Kappa carrageenan was dissolved in each buffer at 80CC and at a concentration of 1% wlv.
Once the carrageenan has dissolved, 1% glucomannan as used in Example 5 product C is added while mixing with a high shear mixer.
The solutions were sealed in cans, heat sterilised at 130"C for 1 hour, cooled and examined.
For comparison purposes, the above exercise was repeated replacing the two gums by 1% of the glucomannan alone in one case and by 1% kappa carrageenan alone in the second case.
The results obtained are noted below.
1% kappa- 1% Glucomannan 1% kappa carrageenan carrageenan and 1% Glucomannan pH 5.5 Thin solution Slightly Tough, slightly viscous solution brittle gel; similar textu re to alginate gels pH 6.5 Ven/ weak, viscous solution Tough brittle gel brittle gel; Excesssyneresis 7.0 Weak, brittle Viscous solution; Tough brittle gel; gel; some some very weak syneresis gel pieces present The gels produced using 1% glucomannan in conjunction with 1% kappa carrageenan were cut into chunks and canned in water. These were then reprocessed at 130 C for 1 hour. After re-processing, the chunks remained integral and discrete.
