Abstract
Description
FRY COATING SYSTEMS USING LONG BRANCH CHAIN WAXY STARCH[0001 I This specification discloses uses of long branch chain waxy starch in fry coating systems. In at least some embodiment the long branch chain waxy starch is a com starch.|0002[ Fried foods are often coated to provide crispiness and texture to an edible substrate. This specification discloses use of long chain waxy com starch, which this specification shows provides high level crispiness to fry coatings compared to common waxy com starch. This high level of crispiness persists even after several minutes elapse between cooking and eating.
[0003] Long branch chain waxy starch as described in this specification is a waxy starch, meaning the starch is substantially free of amylose. The long branch chain waxy starch can be characterized having on average longer amylopectin branch chains than a waxy starch from the same base plant type. For example a long branch chain waxy corn starch will have, on average, longer branch chains than waxy corn starch. In any embodiment the amylopectin of a long branch chain waxy starch has a degree of polymerization on average from 1 to 3 glycosidic units longer than waxy starch from the same base plant.
[0004] The branch chains of long branch chain waxy starch described in this specification may be elongated any suitable means. In some embodiments the branch chains of long branch chain waxy starch may be elongated enzymatically. In other embodiments the branch chains of long branch chain waxy starch are elongated genetically for example by transformation of a plant part of the plant or traditional plant breeding techniques including plant hybridization.
[0005] Long branch chain waxy com starches are distinguishable from common waxy corn starches by reference to the branch chain distribution of their amylopectin. In any embodiment described in this specification a long branch chain waxy corn starch has an amylopectin fraction wherein a percent fraction of glycoside chains having a degree of polymerization (“DP”) between 25 and 36 is from about 17% to about 22%, or from about 18% to about 20%. In any embodiment described in this specification a long branch chain waxy com starch has an amylopectin fraction wherein a percent fraction of glycoside chains having DP greater is than 37 from about 14% to about 18% or from about 15% to about 17%. In any embodiment described in this specification a long branch chain waxy corn starch has a distribution of glycoside chains having an average DP from about 23 to about 26, or from about 23 to about 25.
[0006] Long branch chain waxy com starch of the type described in this specification can be obtained from a hybrid com plant that is homozygous recessive for the waxy trait (wx) and hasAl two doses (of three) of the recessive amylose extender trait (ae). In this specification, such genotype is referred to as an “aewx geneotype,” which can be written as wxwxwxaeaeAE. Hybrid corn plants having an aewx genotype are described, for example, in US Patent Application Serial Number 18 / 098,145, which is incorporated herein by reference in its entirety.[0007J The technology described in this specification can be better understood with reference to the provided figures, which are not intended to limit the full scope of the described technology.BRIEF DESCRIPTION OF THE FIGURES

Cooking times depending on various factors and the cooking type, one-pass or two pass reheating cooking, type of substrate desired level of cook, and others.
[0018] In this specification, “starch” is used as is commonly understood in the art. Without limiting the full understanding of the term, starch is a polymer of glucose molecules and comes in two forms. One, amylose, is a substantially straight chain polymer comprised of a- 1,4 linkages between glycoside units. The other, amylopectin, is a branched polymer comprised of straight chains linked via a- 1,4 linkages between glycoside units. The straight chains have varying length (degree of polymerization). The branch points in amylopectin are comprised of a- 1,6 linkages between glycoside units. Within this specification reference to starch includes starch in all forms, whether modified, native, or gelatinized. With reference to native starch, starch in nature is commonly in granular form. The starch granule, however, may be disrupted by heating starch in water, called gelatinization. Further, whether in granular form or gelatinized form, the starch may be treated chemically, enzymatically, or physically to alter the functionality of the starch. All such forms are called starch in the specification, however, modified starch refers to starch modified in some way, gelatinized or pregelatinized starch refers to starch that is no longer in granular form, granular starch refers to starch that is in granular form, but granular starch may also be modified. Within this specification, whether as an input to a modification process or as the final modified product, reference to starch means aAl powdered composition comprising less than 1% protein (wt.%), or less than 0.5% protein (wt.%) or essentially no protein. For example, a inhibited starch or modified starch refers to a starch that is modified as described and that comprises less than 1% protein (wt.%), or less than 0.5% protein (wt.%) or essentially no protein.[0019J Within this specification, the term “waxy” as applied to starch, for example waxy corn starch, is used as commonly understood in the art. Without limiting the full understanding of the term, waxy means a starch that is substantially free of amylose (less than about 3% or essentially 0%). The long branch chain corn starch described in this specification is a variant of a waxy corn starch meaning that the corn starch is substantially free of amylose (less than about 3% or essentially 0%).[0020| Within this specification, the term “aewx corn starch” refers to a starch from a hybrid corn plant having an “aewx geneotype,” which is a com plant that is homozygous recessive for the waxy trait (wx) and has two doses (of three) of the recessive amylose extender trait (ae), and which can be written as wxwxwxaeaeAE. Hybrid corn plants having an aewx genotype are described, for example, in US Patent Application Serial Number 18 / 098,145, which is incorporated herein by reference in its entirety.[0021 | Within this specification, the term “flour” refers to powdered composition obtained by milling a starch containing plant organ such as a tuber (potato or tapioca), or seed or grain (legumes, corn, rice, etc.) Flour are distinguishable by starches at least by having higher protein content than starch, for example greater than 1 % protein.[0022J Within this specification, the term “fry coating system” refers to a blend of dry ingredients. Fry coating systems may be mixed with water or other aqueous ingredient, or oil to form a batter, and the batter may be used to coat and edible substrate.[0023J Within this specification, “inhibited starch” refers to a starch that has been treated to reduce hydrostatic swelling of a starch granule making it less likely to gelatinize in the presence of heat and water. Inhibition can be done using physical process, for example a thermally inhibited starch, or chemical modification, for example using phosphate or adipate crosslinking.[0024J Use of “about” to modify a number is meant to include the number recited plus or minus 10%. Where legally permissible recitation of a value in a claim means about the value. Use of about in a claim or in the specification is not intended to limit the full scope of covered equivalents.Al[00251 Recitation of the indefinite article “a” or the definite article “the” is meant to mean one or more unless the context clearly dictates otherwise.

[0047] The technology disclose in this specification can be better understood with reference following examples that are provided for illustrative puiposes and are not intended to limit the full scope of the technology.EXAMPLE 1 - CORN STARCH CHARACTERISTICS10048] All long branch chain corn starch evaluated in Examples 1 through Example 5 is from a hybrid corn plant having an aewx genotype.
[0049] Average branch chain length of starch samples was calculated from the molecular number average using ion exchange chromatography as the method of branch chain length separation.
[0050] “Debranching method:” The following starch debranching method was used to calculated degree of polymerization of starch branch chains. Starch samples were added to a mixture containing 90% DMSO and 10% water. The mixture was heated in a boiling water bath under moderate stirring. The samples were then removed from the heat and continued to mix at room temperature overnight. Reagent alcohol was added to each sample to precipitate starch. The starch was then collected via centrifugation. The pellets from each starch sample were diluted in water and cooked in a boiling water bath to ensure full dispersion of the starch. Isoamylase was added to each sample for debranching under the specified pH and temperature conditions for the enzyme. Debranched enzyme samples were then filtered and loaded into the DIONEX ICS-3000 system for analysis.
[0051] A gradient elution profile consisting of sodium hydroxide and sodium nitrate was used for chain length separation. A degree of polymerization (“DP”) 1-7 solution was used as a peak retention time standard. Samples were integrated for peak area using Chromeleon software. Average branch chain length of starch samples was calculated from the molecular number average. Triplicate samples and duplicate injections for each sample were averaged. Results are reported in Table 1.Table 1Branch Chain Distribution of Various Starch
[0052] The average DP of unmodified aewx com starch samples is approximately two glucose units longer than waxy corn starch. Average DP and chain length distribution is very similar for all batches.Gelatinization temperature was identified using differential scanning calorimetry (DSC) and was obtained as follows, starch slurry was made and heated so that the starch was gelatinized. A 3: 1 ratio of water: starch was added to stainless steel pans. The pans were sealed and added to a Perkin Elmer DSC programed to fully gelatinize the starch. Gelatinization peaks were integrated using ThemoCline DSC software which calculated onset, peak, and end gelatinization temperature, as well as enthalpy change.
[0053] Results are reported in Table 2. The unmodified long branch chain corn starch had a higher onset, peak, and end gelatinization temperature than waxy com starch. The unmodifiedA1 long branch chain com starch had onset gelatinization about 2° C higher than waxy com starch. Without being bound by theory, the longer branch chain length of unmodified long branch chain com starch (in comparison to waxy com starch) likely contributes to the higher observed gelatinization temperature. All unmodified long branch chain com starch isolated have similar onset, peak, and end gelatinization temperatures.Table 2Gelatinization Profile of Starch[0054| Retrogradation stability was tested by storing the sealed pans from gelatinization measurement in the refrigerator for one week at 4° C to induce retrogradation. The pans were then added to the DSC which ran the gelatinization program a second time to measure the enthalpy required to break the bonds formed during retrogradation. The average enthalpy measurement of the second scan was divided by the average enthalpy measurement from the first scan (obtained during granule gelatinization) to compare retrogradation percentage or stability- between samples.[0055| Results from retrogradation stability testing are reported in Table 3. The unmodified long branch chain com starch had a lower retrogradation stability than waxy com starches.Table 3Retrogradation Stability of Waxy Com Starch
[0056] Unmodified long branch chain com starch has more retrogradation than waxy com starch. This shows that unmodified long branch chain com starch tends to form firmer compositions over time, which is a trait that can be used to provide differentiated texture compared to starches from other sources.EXAMPLE 2 - EVALUATION OF CORN STARCH IN FRY COATINGS.
[0057] Five fry coating systems were made to evaluate how long branch chain com starch functions in fr ' coatings. Fry' coating systems are based on a “clear coating” system which does not use wheat flour. All samples are reported in Table 4. Sample 1 did not use a waxy starch. Sample 2 uses 5% common waxy com starch in place of crosslinked dent com starch. Sample 3 used 10% common waxy com starch in place of crosslinked dent com starch. Sample 4 used 5% long branch chain com starch in place of crosslinked dent com starch. Sample 5 used 10% long branch chain com starch in place of crosslinked dent com starch.Table 4Fry Coating SystemA1|0O58] Fry coating systems (samples 1 to 5) were used to make fry coating batters. Fry coating batters were evaluated for viscosity. The potato strips were coated, and the fry coating batters were evaluated for percent pick-up. The Cry coating batters, and the battered potato strips were then fried to make French fries. The French fries were evaluated for texture. The process for making the batter and French fries and testing methods used follow.
[0059] Russet potatoes, peeled and cut to 3 / 8 inch (about 0.95 cm) size strips were blanched in hot water (165° F to 180° F (about 71° C to about 82° C) for about 4.5 minutes (until soft but firm). Blanched potatoes were dipped for 45 seconds into a hot brine (165° F (about 71° C) and 0. 1-0.5 wt.% salt and optionally 0.5% sodium acid pyrophosphate (SAPP) #28 in water). Potatoes were dried with hot arr to a moisture loss of about 13% (wt.% change from wet to dry ). Fry coating batter was made by mixing the fry coating systems said in Table 4 with water to obtain a mixture having 42% (wt.%) solids. Batter viscosity' was measured using #4 Zahn cup.|00601 Potato strips were coated by dipping the substrate in a bowl with the fry’ coating batter. Percent batter pick up was measured. Coated potato strips were par-fried for 50 seconds in preheated oil (380° F (about 193° C)) and then frozen using a forced air blast freezer (1 hour at between -10° F and -20° F (about -23° C and -29° C)). The frozen potato strips were then transferred to a standard freezer (0° F to -10° F (about -17 to about -23° C)) and held until reheating. Prior to testing, strips were refried (from frozen) in 360° F oil (about 182° C) to make the final French fry. French fries were then held under heat lamp (turned off after 10 minutes hold time) and portions were evaluated after 5 minutes hold time (heat lamp still on) and 15 minutes hold time (after heat lamp was off for five minutes off). Eating quality of fried potato strips was evaluate by and employee panel.A1EXAMPLE 3 - WHEAT FREE BATTER CHARATERISTICS[00611 Fry coating batters were evaluated for batter viscosity and percent batter pick-up (important attributes in industry). Viscosity was measured using a Zahn Cup (size #4), which is a common method in the industry for measuring ry coating batter viscosity’. (See e.g. https: / / www.coleparmer.eom / p / cole-parmer-zahn-style-viscosity-cups / 65716?Ntt=zahn - last accessed 11 January’ 2024). Zahn cups are cups of standardized size and having a standardized hole in the bottom. Size #4 designates a size of cup and whole. Fry' coating batter viscosity' was measured by filling the cup and measuring the time it takes the cup to drain a set amount of batter. The cup was filled and the time (in seconds) for the sample to drain from the whole in the bottom of the cup was measured.|0062] Percent batter pick up is the amount of batter on the fries after coating following dipping the substrate in a bowl containing the batter. Percent batter pick was measured as the percent change in weight between the battered potato strip and the unbattered potato strip. Results are reported in Table 5.Table 5Fry Coating Batter Viscosity’ and Percent Batter Pick-up[0063| Samples using long branch chain com starch are marked in bold italics. As samples are shown to have similar fry coating batter viscosity and percent pick-up.EXAMPLE 4 - TEXTURE QUALITY FINISHED FRIED POTATO STRIPS.[0064| Potato strips, made and held as described in Example 1, were observed both for physical changes at the surface and were evaluated for sensory' texture changes at 5-minutes, 10 minutes, and 15-minutes as described. Observers were company staff. No significant or changes in physical appearance were observed. Fried coating was not observed to have ridges, lumps, or physical anomalies nor were these observed to form during the hold period.A1[0065| Sensory texture was observed using blind tasting. Observers were presented samples randomly one at a time (random monadic order). Testers rate samples on crispiness using a scale from 1 to 5 with 5 representing a high degree of crispiness and 1 representing a low degree of crispiness. Results are presented in Figure 1, which is a bar graph presenting different samples on the horizontal axis and crispiness rating on the vertical axis (Figure 1 refers to Samples 1 as Negative Control R; Sample 2 as #1AR, Sample 3 as #1BR, Sample 4 as #2AR, and Sample 5 as #2BR) . Testers also provided comments were written down. Summarized evaluations of samples held for 5 minutes are presented in Table 6 and summarized evaluations of samples held for 15 minutes are presented at in Table 7.Table 6Texture of Fried Potato Strips, 5-minute Hold TimeTable 7Texture of Fried Potato Strips, 15-minute Hold Time[00661 Samples using long branch chain com starch are marked in bold italics. In summary , samples using long branch chain com starch were crispier than samples using common waxy com starch or sample using no waxy com starch. Crispy texture of samples using long branch chain com starch persisted through hold time. Best overall sample was sample 4. Without being bound by theory the improved crispiness of long branch chain com starch samples may result from the higher retrogradation enthalpy of the starch.
[0067] With reference to Figure 1. coated fried potatoes using long branch chain com starch had higher crispiness ratings at lower usage. For example at 5 minutes Sample #1BR (Sample3) using 5% long branch chain com starch was rated as crispy as Sample #2AR (Sample 4) using 10% waxy com starch. At 5 minutes, Sample #2BR (Sample 5) w as the crispiest. Similar results are seen at 10 minutes. Notably at 15 minutes, which is 5 minutes after the fried potato strips were removed from the heat lamp, Samples using long branch chain waxy com starch were crispier than samples using waxy com starch regardless of usage level. Compare, for example, Sample #1BR with Sample #2AR.EXAMPLE 5 - EVALUATION OF WHEAT FLOUR CONTAINING BATTERS COATING CHICKEN(0068] This example compares the texture of a tempura style wheat flour containing fry batters made using waxy com starch and long branch chain waxy com starch. Samples batters were evaluated for viscosity and percent batter pick and finished fried chicken product was evaluated by an employ panel. Testing methods were the same as reported in Examples 3 and 4, except as explicitly said in this Example 5.
[0069] Dry ingredients and amounts used to make the batter for this Example 5 are said Table 8.Table 8Fry Batter Formula for Fried ChickenA1100.00% 100.00% 100.00% 100.00% 100.00%
[0070] Dry ingredients were mixed with water to form a batter having 40% solids (wt.%). Chicken substrate was removed from bone and cut into rough cubes. Chicken was coated without using a pre-dusting by submerging chicken cubes in the fry batter. Coated fried chicken was par fried until fully cooked (internal temperature of about 74° C).[0071 Batter viscosity was measured using a number 5 Zahn cup. Batter viscosity and percent batter pick up are reported in Table 9.Table 9Fry Coating Batter Viscosity and Percent Batter Pick-up|0072] Samples using long branch chain com starch are marked in bold italics. Texture was evaluated in the same matter as described in Example 3. Samples were rated on a scale from 1 to 5 within 5 having the highest crispiness. Results are reported in Figure 2 (Sample 6 = negative control, Sample 7 = #5 A, Sample 8 = #5B, Sample 9 = #6A, and Sample 10 = #6B). Figure 2 is a bar graph with samples listed on the horizontal axis and rating listed on the vertical axis. As seen, had higher crispiness rating at 5 minutes and 10 minutes and higher crispiness regardless of usage. At 15 minutes, which was five minutes after being removed from the heat lamp, long branch chain com starch provided better crispiness for amount used. For example,Sample #5B, using 5% long branch chain com starch, had equal crispiness to Sample #6A, which used 10% waxy com starch.
