Evaluation of Hard White Winter Wheat Breeder Lines for Alkaline Asian Noodles

Rationale/Background

About 40 percent of wheat products consumed in Asian countries are in the form of noodles (1). As the largest wheat exporter country in the world, the United States needs to maintain its competitiveness in producing the wheat quality that is wanted by more sophisticated buyers. When Asian consumers choose wheat for noodle manufacturing, buying decisions are based on the final color and texture characteristics (1).

 

The interest in hard white winter wheat (HWWW) has been generated by competition of Australian Standard White wheat from western Australia, which has been tailored for white salted Asian noodles  (2).

 

The interest in HWWW has grown in wheat producing states in the U.S. and overseas markets. White Winter varieties may not only produce brighter and whiter flour than the red winter wheat varieties, but they also lack the bitter aftertaste given by polyphenols present in the red wheat varieties.

 

The objective of this research was to compare the quality of Alkaline Asian noodles made from HWWW advanced breeder lines and commercial white varieties grown in different locations in Oklahoma.

 

Materials and Methods

 

Wheat Lines/Varieties 

Eight HWWW advanced breeder lines and two commercial varieties grown in three locations (Altus, Fort Cobb and Sweetwater, Okla.) were donated by Brett Carver, wheat breeder at Oklahoma State University. Eltan (Soft White Winter) and Nu-West (Hard White Winter) varieties from Washington and Montana, respectively, were used for comparison. All samples were milled in a Quadromat Sr. mill (C.W. Brabender, Hackensack, N.J.).

 

The table below shows the counties to which the locations belong and their annual wheat production in  million bushels in the crop years 1998 and 1999.

Protein Analysis

Flour protein content was measured using a near infrared (NIR) spectrometer (Perten Instruments, Reno, Nev.) and the percent protein was calculated on a 14 percent moisture basis.

 

Noodle Preparation

Alkaline noodles were prepared from 200 grams of flour and 10 milliliters alkaline solution containing 0.5 percent Na2CO3 and 2 percent NaCl. Water absorption levels were adjusted to obtain an optimum sandy dough. Noodles were processed in a laboratory scale noodle machine (H. H. Kejentaraan, Malaysia) adjusting the reducing roll gap from 4.0 to 1.0 millimeters in seven steps. Pieces (6 square centimeters) of the dough were saved for color evaluation. The L*, a* and b* color space was measured in a Minolta colorimeter (Minolta Ltd., Osaka, Japan) using a double layer of the raw dough at two and 24 hours after preparation. The dough pieces were stored in plastic bags at room temperature (26oC).

 

Peak viscosity was measured in a flour-water slurry at a 4 to 25 ratio (w/w) using a Rapid Visco Analyzer (Newport Scientific, Sydney, Australia). Objective textural properties were measured with a Texture Analyzer, TA-XT2i (Texture Technologies Corp., N.Y.). The test consisted of two compressions using a standard cylindrical plunger (probe) descending to a preset distance in the noodle with a constant load increase over the time it was used. Five independent observations were made on five, cooked noodle strands (two centimeters long) placed side by side. Due to the limited amount of wheat from the breeder program, all analyses were completed in a single experimental unit with sub samplings.

 

Results

 

Protein Content

The flour protein content ranged from 8.3 to 13.0 percent (Figure 1). Wheat lines and varieties grown in Altus showed a higher percentage of protein than Fort Cobb and Sweetwater. The percent protein of wheat line OK97G611 showed the largest variability while OK98G504W was less variable between locations. Averaging the three locations, OK98G505W contained the highest percent protein (10.5 percent) among the breeder lines tested. Comparing the average protein of the commercial varieties, Betty had a higher (12.5 percent) and more consistent protein content compared to Oro Blanco and wheat lines in all locations. Oro Blanco had similar average protein content compared to all the wheat lines tested.

 

Percent protein of flour from HWWW breeder lines and commercial varieties grown in three Oklahoma locations in the 1998-1999 crop year.

 

Gain Weight

Noodles (35 grams) were cooked in boiling water for two minutes, rinsed with tap water, drained by tapping 10 times, stored in water and immediately analyzed. Gain weight was calculated as a percentage using initial and final weights. A higher value of gain weight will produce higher yields and thus more profits for the processor. Breeder line OK98G502W gave the highest (116.4 percent) and less variable gain weight among the lines and varieties in all three locations (Figure two). Wheat line OK97G611 had the lowest gain weight (94.1 percent) among the lines and varieties in all the locations. Breeder lines OK98G506W and OK98G507W exhibited the greatest variation of gain weight between locations. The commercial varieties, Betty (110.5 percent) and Oro Blanco (114.0 percent), showed higher and less variable gain weight in all locations.On average, Oro Blanco was similar to breeder line OK98G502W (116.4 percent).

Color

Asian customers prefer bright and yellow alkaline noodles with a stable color after 24 hours of preparation. Objective measurement of color is conducted by a colorimeter that gives values of brightness (L*), yellowness (b*) and redness (a*). Desirable values for L* are higher than 60 with a maximum value of 100 for bright noodles and a value of 50 for a gray, dull color. Lower values, less than 50, indicate a general darkness of the noodles. The a* and b* are the color coordinates: +a* and –a* are the red and green directions and +b* and –b* are the yellow and blue directions, respectively. The +a* and +b* values range from 10 to 60 and between 0 and < 10 results on gray and dull color. In alkaline Asian noodles, the basic pH enhances the xanthophylls or yellow pigments in the flour. Redness +a* values are an undesirable hue in alkaline noodles, the lower the value the better but too low will produce a dull gray color.

 

Brightness (L*)

Table 1a shows the change in brightness of the alkaline Asian noodles from two to 24 hours. Delta (Δ) L* is an estimate of the stability of the noodle brightness. Lower ΔL* values (2.7) of noodles made from breeder line OK97G611 were observed (Table 1a) and ranked first among the lines and varieties in all locations. The ΔL* was lower than Betty (7.2) and Oro Blanco (5.1) which ranked seven and four, respectively. Only breeder line OK97G611 gave a comparable ΔL* value to Eltan (3.0) and Nu-West (2.3) while the other samples gave higher ΔL* values indicating a larger decrease in brightness.

 

Yellowness  (b*)

The majority of the change in yellow (Δb*) values in the samples tested were relatively small and negative, average b*, -3.0 (Table 1b). In comparison to Eltan (1.1) and Nu-West (1.7), the breeder and variety samples grown in Oklahoma indicate a marked deterioration from the original yellowness of the dough.

 

Redness (a*)

All the dough samples of Oklahoma-grown wheat showed small but negative Δa* values ranging from – 0.1 to – 0.7 (Table 1c). These values are at the center of the color space (map) where gray color resides. Wheat lines OK98G504W and OK98G506W ranked as number one while the commercial varieties ranked nine (Betty) and five (Oro Blanco). The Δa* values from the breeder lines and varieties i this study demonstrated a shift to a grayish hue, which is undesirable in alkaline noodle.

Alkaline noodle should be bright (high L*) and display good yellow color (high b*).

Higher negative a* value means more green noodle.

Higher positive a* value means more red noodle.

 

Starch Peak Viscosity

Overall, the Sweetwater location showed the highest peak viscosity of flour while Altus had the lowest. High peak viscosities are associated with desirable texture characteristics in white noodles (5).

 

Peak viscosity of flour made from hard white winter wheat breeder lines and commercial varieties grown in three Oklahoma locations in the 1998 to 1999 crop year.

 

Texture

Objective evaluation of textural properties that are reproducible and not subject to regional taste and evaluator’s fatigue is valuable in breeding programs for screening purposes. There are a number of literature reports on textural properties of Asian noodles using sensory (subjective method) evaluation with trained panelist from particular regions in Asia (5, 2, 7). However, it is more challenging to find native Asian evaluators from several regions and their commitment of time for constant noodle evaluation sessions.

 

Hardness is a measure of the firmness of the noodles and probably the most important texture parameter. Hardness was measured as the maximum peak of the first compression. Smooth surface and higher elasticity (springy) properties are preferred in cooked Chinese wet alkaline noodles (5). In this study, the average score for hardness was 1551 ± 132 (Table 2a) from all samples and locations. The majority of the breeder lines and varieties were comparable to the firmness score of Nu-West (1567) and higher than Eltan (1147). The firmest noodles were obtained from breeder line OK98G508W (1791) and the softest was line OK97G611 (1402). Nevertheless, the softest among the wheat lines and varieties scored higher than Eltan. However, Eltan showed the highest resilience value (Table 2c), meaning it produces a soft but resilient noodle structure.

 

Springiness is a measure of the ability of the noodle to bounce back after a pressure is applied. In the TPA analysis, springiness is calculated as the length (X axis) of the two compression peaks, from the baseline to each peak. Springiness correlates with how rubbery noodles are perceived. Average springiness scores ranged from 0.95 to 1.04 ± 0.02 in all locations (Table 2a). The majority of the samples had springiness values similar to Nu-West except for OK97G611 (0.97), OK95G701 (0.95), and Oro Blanco (0.95), which had similar values to the comparison variety Eltan (0.95).

 

Cohesiveness is measured by the ratio of the two compression areas. It is related to the extent to which noodle structure is disrupted during the two compressions by the testing probe. This measurement is associated with sensory evaluation of the noodle bite and springiness. The more cohesive noodles in the group were obtained from lines OK98G504W and OK98G506W (0.70) (Table 2b). These noodles have similar cohesiveness score to Nu-West (0.71) but lower than Eltan (0.78). In contrast, the less cohesive noodle was made from OK97G611 (0.56). Overall, wheat lines and varieties tested had cohesiveness score of 0.65 comparable to Nu-West (0.71).

 

Gumminess is the energy required to disintegrate a semisolid food to a state ready for swallowing and is a combination of hardness and cohesiveness (6). The overall gumminess score for all the samples in the three locations was 856 ± 126 which is within the range of Eltan (812) and Nu-West (961). Wheat line OK98G504W demonstrated the highest score (1050) for gumminess compared to all the wheat lines and varieties Eltan and Nu-West (Table 2b). In contrast, OK97G611 conferred the lowest score (620).

 

Chewiness is a combination of hardness, cohesiveness and elasticity (6). Subjectively, chewiness is measured by “tooth packing”, where the evaluator uses molar compression on the noodles and then assesses how much the noodle’s structure springs back. In this study, the average score for chewiness of all the samples across the locations was 846 ± 136 (Table 2c). Wheat line OK98G504W gave the highest score for chewiness (1060) while OK97G611 had the lowest score (598). Three lines OK98G506W, OK98G507W, and OK98G508W had similar chewiness score (938) to the Nu-West variety.

 

Resilience is the ability of the noodles to regain their shape after being compressed. In theory, this measure is positively correlated with elasticity. The overall score for resilience was 0.35 ± 0.05 (Table 2c). This score is similar to Nu-West (0.35) but lower than Eltan (0.50). The most resilient noodle was obtained from OK98G506W (0.43) and the least resilient from OK95G701 (0.28).

 

Adhesiveness is a negative force after the first compression cycle and is a measure of how sticky, tacky or gooey the noodles are (6). All samples adhered to the probe with an overall score of  -52.76 ± 14.57. This value is similar to Eltan (-50.0) but higher than Nu-West (-34.5). Wheat lines and varieties with higher adhesiveness than Eltan (-50.0) were OK98G504W (-73.0), OK98G505W (-60.4), OK98G506W (-67.1), OK98G504W (-66.5), and Oro Blanco (-58.2). Only wheat line OK98G507W (-29.1) had lower adhesiveness than Nu-West (-34.5), and was the top ranking sample in this property.

Conclusion

The texture of alkaline noodles has been reported to be influenced by quality and content of protein and starch characteristics (5, 4). Functionality of the protein and starch control the quality of the end product. In white salted noodles, a negative correlation of high protein content with brightness of noodles has been reported (4).  In this report, the variety Betty and location Altus that produced the highest protein content also produced the darkest noodle. Eltan exhibited a lower value for the textural properties of firmness/hardness but it was the most resilient and cohesive sample.

 

Among the breeder lines, OK97G11 demonstrated a promising noodle color stability having the brightest color after 24 hr. However, this line also showed the lowest rank in all textural properties except for adhesiveness and had the lowest gain weight. Compared to the commercial varieties Eltan and Nu-West, OK97G11 line is short in three out of seven textural properties (cohesiveness, gumminess and chewiness). A promising breeder line in terms of texture characteristics is OK98G504W, which shows top values for hardness, springiness, cohesiveness, chewiness, gumminess and resilience values. The textural property that is deterrent in this line is the highest adhesiveness value. It also had the least stable color with the highest decrease in brightness ΔL* after 24 hr. Overall, the Sweetwater location showed a trend to higher L* values translated into brighter noodles. The weight gained by the noodles after cooking showed large variation with no distinguishable trend at any specific location.
