FOOD Application

Snacks. High amylose cornstarch is also used in extruded and fried snack products to obtain crisp, evenly browned product and hampers penetration of cooking oils. High amylose cornstarch requires higher cooking temperatures, typically 150-170 oC, to gelatinise properly.

Tapioca starch exhibits good clarity and bland flavour. It has good film-forming characteristics with resistance to cracking and chipping. It may be used at a concentration of twenty per cent. The film-forming properties of Tapioca dextrins make it effective as a replacement for gum Arabic in the pan coating of confections. This dextrin can be used as a non-tacky glaze for cakes, donuts, fruit, nuts and candies.

Baking. High maltose and high conversion syrups improve moisture retension and colour control in final product. Dextrose syrup improve crust and doug properties. High fructose syrups are used in frosting and fillings.

Baby food. Maltodextrin and starch is used as a nutrient with low fermentability. Dextrose as an energy source

Noodles. Adding potato starch or better a dual esterifed starch with low gelatinisation point and a high peak viscosity to noodles improves their consistency and mouthfeel. The starch will gelatinise and absorb water before the wheat flour takes over and dominate the viscosity profile.

Sauces. A pizza sauce gets improved eye appeal and mouthfeel from a cold water swelling pregelatinized starch. A cross-linked instant starch is easy to disperse in cold mixtures or oil and adds a pulpy and richer look to fruit based sauces. Cross-linking imparts the starch with resistance in acid foods and will even allow retorting.

Meat products. Modified waxy maize, potato or tapioca starch added at the chopping stage swells during heating and binds in poultry rolls and meat loaves as well as other cooked meats. The final texture will be firm and retained for prolonged periods. Starch may reduce drip during smoking of meats and weeping of vacuum packed foods. Starch is also used as a skim milk in replacer.

Low calorie foods. HFSS 90 is used in low calorie food applications, due to its high sweetening power to calorie ratio.

Tapioca based modified starch can be used as a fat mimetic in dairy systems due to its bland flavour. A low-fat product can be prepared with the organoleptic and textural properties of a traditional fat containing product.

Beverages

Soft drinks. High fructose starch-based syrup (HFSS), although originally introduced in 1967, it was the fructose level increase to 55% in 1978 which resulted in sugars loss of the soft drink market. HFSS can be produced at considerably lower costs than sugar, giving this product a competitive advantage over sugar.
High fructose starch-based syrups (HFSS) are used for soft drinks as a sugar replacement with similar sweetness. HFSS 55, is a most concentrated sweetener used primarily in beverages. It is a direct replacement of sugar. HFSS 42, an all-purpose sweetener, does also find uses in beverages. HFSS stabilize the flavour profile.

Beer. High maltose syrups find use as wort syrup in beer production. It is an excellent fermentation substrate and fermentation can be controlled by the sugar spectrum of the syrup. Some yeast species are sensitive to high concentrations of glucose but maltose does not have any suppression effect on yeast.

Alcohol. Very high DE glucose syrups are used as a fermentation booster in alcohol fermentation. Dextrose syrup has the advantage, that it is completely used up and do not add to by-products and may improve throughput when capacity is exhausted.

Instant coffee. Following conventional coffee cleaning and roasting the prepared coffee is ground and extracted in counter current column batteries using split or fraction technique to optimise yields or by using continuos extraction. The extract is concentrated in falling film evaporators or rotary thin film concentrators with final blending to produce a prime quality concentrate. A maltodextrin (low DE glucose syrup) may be added as a carrier or extender. The concentrate is conducted in a co-current nozzle tower and the coffee powder is discharged in cooled free-flowing form ready for packing. Further agglomeration   produces a coarser product.

Confectionary

Ice cream. Starch products are used as crystal and texture controller. High maltose and high conversion syrups control softness and freezing characteristics.

Today's ice cream has the following composition:

greater than 10% milkfat - usually between 10% and as high as 16% fat in some premium ice creams
9 to 12% milk solids-not-fat: this component contains the proteins (caseins and whey proteins) and carbohydrates (lactose) found in milk
12 to 16% sweeteners: usually a combination of sucrose and glucose syrup
0.2 to 0.5% stabilizers and emulsifiers
55% to 64% water which comes from the milk or other ingredients

A sweet ice cream is usually desired by the consumer. As a result, sweetening agents are added to ice cream mix at a rate of usually 12 - 16% by weight. Sweeteners improve the texture and palatability of the ice cream, enhance flavors, and are usually the cheapest source of total solids. In addition, the sugars contribute to a depressed freezing point so that the ice cream has some unfrozen water associated with it at very low temperatures typical of their serving temperatures, -15 to -18 C. Without this unfrozen water, the ice cream would be too hard to scoop.
It has become common in the industry to substitute all or a portion of the sucrose content with sweeteners derived from starch syrup. This sweetener is reported to contribute a firmer and more chewy body to the ice cream, is an economical source of solids, and improves the shelf life of the finished product. Starch syrup in either its liquid or dry form is available in varying dextrose equivalents (DE). As the DE is increased by hydrolysis of the starch, the sweetness of the solids is increased and the average molecular weight is decreased. This results in an increase in the freezing point depression, in such foods as ice cream, by the sweetener. The lower DE starch syrup contains more dextrins which tie up more water in the mix thus supplying greater stabilizing effect against coarse texture.
HFSS High fructose starch-based syrup can be used to a much greater extent in sucrose replacement. However, these HFSS further reduce the freezing point producing a very soft ice cream at usual conditions of storage and dipping in the home. A balance is involved between sweetness, total solids, and freezing point.

Confectionery. High conversion glucose syrups replase sucrose and imparts products with less hygroscopicity and a better viscosity profile. High maltose syrups controls moisture and texture in soft confections.

Candy. High amylose cornstarch contains as much as 70% amylose compared to 25-28% in ordinary cornstarch. This makes it a particular strong gelling agent in the manufacture of fine jelly gum candies. High amylose cornstarch is used in combination with normal fluidity starches (thin boiling starches). Up to half the starch is commonly replaced by high amylose starch to obtain quick setting candy piece with an attractive texture.

Tapioca speciality dextrins replaces from 20% to 40% of gum Arabic in some hard gum candies.

High-Boiled Sweets. High-boiled sugar confectionery is expected not to be sticky or crystallised when reaching the consumer. The stability with respect to moisture pickup and stickiness depends on its ERH. The ERH of high- boiled sweets is approximately 30%, and since the atmospheric humidity is nearly always above this, there is a tendency to absorb moisture from the atmosphere.
Initially this occurs on the surface, with a thin film of a solution of lower solids forming with a lower viscosity. This in turn leads to crystallization of the sucrose (graining). To produce high-boiled sweets with a satisfactory shelf life, the final product must contain a minimum amount of residual moisture and the correct balance of sugar and glucose. To obtain a product with satisfactory texture and shelf life, a combination of sucrose and glucose in a 60:40 ratio is generally used. Medium conversion glucose syrup (42DE) is commonly used, which contains a wide range of simple to higher sugars. This is more resistant to water absorption from the atmosphere due to a raised ERH value and is less liable to grain, however, there are some downside effects - such as a higher viscosity, which makes the finished product difficult to crunch; the sweetness level is lower. Some of these can be overcome by the use of more specialized syrups such as High Maltose.

The use of invert sugar as a doctor in high-boiled sweets has all but been replaced by glucose syrup. Glucose syrup (42 DE) exhibits a higher relative vapour pressure and at the levels required to prevent sugar crystallization, the invert sugar will cause serious stickiness due to hygroscopicity.

Marshmallows. As marshmallows have a soluble solids content of 78-80%, the prevention of crystallization depends on the choice of an effective doctor carbohydrate. The hygroscopic nature of these products is again influenced by the ERH and marshmallows have an ERH range of 65-75%.

When considering an appropriate doctor for marshmallow, we find the use of invert sugar, 42DE glucose syrup and 63 DE glucose syrup. When comparing the relative vapour pressure, we find that where invert sugar is used, the relative vapour pressure (73.3%) is lower than when glucose syrups are used and therefore will pickup moisture from the atmosphere. This is important to remember if selling product in high humidity markets.

The use of 42 DE glucose will give lower moisture pickup, but may not deliver the desired sweetness or texture levels. It may be more desirable to use 63 DE glucose. This will retain more moisture and facilitate faster whipping, (due to a lower viscosity) and deliver a higher sweetness level.

Marmalade and jam. For proper texture, jellied fruit products require the correct combination of fruit, pectin, acid, and sugar.
Sugar serves as a preserving agent, contributes flavor, and aids in gelling. Cane and beet sugar are the usual sources of sugar for jelly or jam. Starch syrup may be used to replace part of the sugar in recipes, but too much will mask the fruit flavor and alter the gel structure. Too little sugar prevents gelling and may allow yeasts and molds to grow.
Medium high glucose syrup - 63 DE - replaces sugar in marmalade and jam. To provide good shelf life a high sugar concentration is required and for the purpose a 63 DE syrup is preferred to the traditional 42 De syrup. High conversion syrups and HFS adds more sweetness and increase osmotic pressure (better shelf life).

Canning. Maltodextrins and low conversions syrups add body to canned sauces. High conversion syrups add body and sweetness to canned fruit. HFS add seetness.

Stain remover. To remove a stain with an absorbent powder, sprinkle a layer of starch powder over the stain. Spread the starch round, and as soon as it becomes gummy lift, shake or brush it off. Repeat this until nothing further is being absorbed. If a mark still remains after this, mix the powder to a paste, using water for non-greasy stains and a grease solvent (see "for greasy marks"). Leave standing till dry, then brush off.

Dusting powders. Dusting powder consists of finely powdered substances free of grittiness. They are used on normal intact skin prophylactically to reduce friction (talc) or moisture (starch). By cross-linking starch can be stand sterilising in autoclave and be used as surgical dusting powder.
