[0031] Starch according to this invention has two main polysaccharides amylose and amylopectin. Starches granules can be isolated from a wide variety of plant sources, consisting of tuberous root, tuber and seeds. Based on the botanical origin, starch granules come in different shapes, sizes and have varying ratios of amylose/amylopectin. Starch according to this invention is a native starch, physically modified starch, flour, pre-gelatinized starch or cold swelling starch or combination thereof. In a further preferred embodiment, the non-dairy cheese analogue does not contain a chemically modified starch. The starch according to the invention is selected from the group consisting of maize, waxy maize, high amylose maize, wheat, tapioca, rice, potato, cassava or combinations of these. Corresponding flours can also be used as a source of starch. The person skilled in the art knows how to calculate, based on the amount of starch, how much flour has to be used to fall within this invention. Native starch is defined as a starch granule in its native form in the nature; isolated using the extraction processes. Native starch granule is in a semi-crystalline form and have a crystallinity varying from 15 to 45%. Other prominent feature of a native starch granule is its presence of Maltese cross when observed under polarized light. Due to the presence of the order in the native starch, it exhibits birefringence under polarized light. Gelatinized starch is the native starch, which undergoes gelatinisation process. The gelatinization process occurs when the native starch granules are heated progressively to higher temperatures in the presence of excess of water, the granules begin to irreversibly swell and there is a point at which the Maltese cross of the native granules disappears. During gelatinisation several events occur simultaneously. There are three distinct stages that occur in the gelatinization process: (i) granular swelling by slow water absorption; (ii) followed by a rapid loss of birefringence via the absorption of large amounts of water by the granules; and (iii) finally, leaching of the soluble portion into the solution, transforming the granules into formless sacs. Size, shape of the granule and the loss of birefringence are the distinctive feature of the gelatinized starch. Gelatinized starch can be sourced commercially as pre-gelatinized starch. Swollen starch granule or partly gelatinized is produced when the native starch granules are heated progressively to higher temperatures in the presence of excess of water; the granules begin to irreversibly swell and Swollen starch granule or partly gelatinized is an intermediate stage between the native starch granule form and gelatinisation. The granules in the swollen form have a larger granular size than the native starch granule and could have a partial or complete loss of birefringence. In a further embodiment, the non-dairy cheese analogue of the invention comprises starch in the amount of 5 to 25 wt % (weight percent of the total composition), preferably 10 to 25 wt %, preferably 12 to 22 wt %, preferably 13 to 21 wt % (weight percent of the total composition).

In a preferred embodiment the lipid is a blend of coconut oil and sunflower oil, rape seed oil, cotton seed oil, peanut oil, soya oil, olive oil, algal oil, safflower oil, corn oil, rice bran oil, sesame oil, hazelnut oil, avocado oil, almond oil, walnut oil or canola oil.

EXAMPLES

Example 1: Process

[0039] Vegan cheese samples were made in 2-Kg batches using Stephan kettle. The dry ingredients were blended in the Stephan cooker. Fat component was added and mixed at slow speed to disperse the dry-ingredients and avoid forming lumps. Water was subsequently added; the blend was mixed at maximum speed-setting of II (i.e. 1500 rpm) and heated to a temperature of 80? C. and held for 2 min before packing in a plastic container and cooling in a walk-in cooler (4? C. or lower). Samples were stored for at least 10 days at 4? C. before shredding. Allowing the samples to equilibrate for 10 days appeared to have improved shredding properties.

Melt Score and Tooth Sticking:

[0040] Samples were evaluated on a pizza crusts topped with vegetarian cheeses. The panelists evaluated one sample at a time, scoring based on intensity for each attribute (0-5 scale). [0041] Melt score 0=visible shreds after cooking 5=no shreds after baking, full melt [0042] Tooth sticking 0=no sticking 5=max sticking

Peak Force and Area Using Texture Analyzer:

[0043] Texture profile analysis (TPA) was carried out using a TAXT2i texture analyzer (Stable Micro Systems, Godalming, UK). The TPA curves were used to derive the instrumental texture attributes including Peak force and Area, both of which are indicators of hardness, which can be defined as the force necessary to attain a given deformation.

[0044] In this method, five representative samples of cheeses were cut into a cylinder shape (dimensions: 20 mm diameter and 20 mm height). A double bite compression method was used with a rest period of 2 seconds between the two bites. The samples were compressed to 80% (16 mm compression) of their original height using a 50 mm cylindrical flat probe with a crosshead speed of 0.8 mm/s.

G at 50? C., 60? C., and 70? C. Using Dynamic Oscillatory Rheometry:

[0045] Dynamic Oscillatory Rheometry offers a method to indirectly probe the structure of cheese analogues over a range of experimental time scales, extents of deformation, and temperatures. Small amplitude oscillations are imposed upon the cheese analogue sample, such that the strains are within the linear viscoelastic region where any structural breakdown is largely reversible within the time-scale of the experiment. Exceeding this limit causes the cheese analogue structure to change and re-form into a different conformation upon cessation of the oscillatory strain. The experimental time scale is defined as the reciprocal of the oscillation frequency. Large time scale experiments (at slow frequency) allow sufficient time for flow units within a sample to move and rearrange during the experiment, thus the sample is more fluid-like. Short time scale experiments do not allow sufficient time for the flow units to move, thus the sample is more solid-like. The degree of solidness is quantified by the elastic storage modulus (G). The elastic modulus is calculated from the ratio of stress to strain, so for a given applied stress, any factor that reduces the strain will increase the elasticity and firmness. For high values of G, the material is more solid or gel-like, whereas lower values indicate a more fluid-like substance.

[0046] Analysis was conducted using MCR 200 (Anton Paar), PP25/P2 Serrated Parallel Plate Geometry, and H-PTD200 Peltier Temperature Control Device. Samples were cut in to 25mm diameter and 2 mm thickness, and were allowed to temper to refrigerated conditions prior to use. AntonPaar software was used to operate the rheometer and record and analyze data. The water bath and the compressed air were turned on. The normal force was reset and that the height was calibrated, every time prior to running a sample. The cheese analogue disc was placed in the center of the bottom plate and the measurement height was selected. The hood was lowered and made sure that the temperature was set to 20? C. The cheese analogue was allowed to temper for 5 to 10 minutes before running the test. Temperature of sample was increased from 20? C. to 90? C. at the rate of 1? C. per minutes and storage modulus (G) was recorded at constant shear strain 0.5% and constant frequency 1 Hz.

[0048] Comparative example 1 to example 13 show the influence of a gum to modulate the melting properties and tooth stickiness of a non-dairy cheese analogue. Without a gum (comp. example 1) the non-dairy cheese analogue has the best melting rating but also is the worse example regarding tooth stickiness. A balanced rating between melting properties and tooth stickiness can be achieved if the non-dairy cheese analogue composition comprises between 0.05 to 2.5 wt % gum, especially between 0.15 to 2 wt % gum. Above 2.5 wt % of gum the melting properties of the non-dairy cheese analogue composition will be lost.
