Surimi (or fish paste) products are one of the most representative processed seafoods in Korea. In a previous study, we evaluated the potential use of rice flour as an agent to replace wheat flour in surimi products. In this study, we optimized the content of rice flour and water in surimi products using response surface methodology. Rice flour content (
X
_{1}
, w/w) and water content (
X
_{2}
, v/w) were chosen as independent variables and gel strength (
Y
_{1}
) and overall acceptance (
Y
_{2}
) as dependent variables. Optimal conditions of
X
_{1}
and
X
_{2}
were 14% and 9.1%, respectively, and the predicted values of the multiple response optimal conditions were
Y
_{1}
= 656.4 (g∙cm) and
Y
_{2}
= 6.34. Under optimal conditions, the experimental values of
Y
_{1}
and
Y
_{2}
were 647.8 (g∙cm) and 6.21, respectively, which were similar to the predicted values. Surimi products that are prepared under optimum conditions were similar in gel strength to those of commercial products. However, its sensory evaluation score was higher than that of the commercial products. In conclusion, rice flour can not only be used as an alternative to wheat flour, but it also can be used to improve the quality of surimi products.
Lycii fructus
(Shin et al.,
2008
), and
Poria cocos
(Shin et al.,
2009
) have been reported. Currently, there exists few papers on the use of rice flour as a gel-enhancing ingredient in surimi products studied (Jung and Yoo,
2005
;Jung et al.,
2007
;Hur et al.,
2011
). However, the relationship between rice flour and surimi with regard to rheological properties and sensory evaluation has not been fully elucidated. In particular, no attempt has been made to optimize the content of rice flour in surimi products. In a previous study, we evaluated the effect of rice flour addition on the rheological and sensory properties of surimi products to check for the feasibility of using rice flour as an alternative to wheat flour for the production of premium surimi products (Cho et al.,
2013
). Therefore, the objective of the present study was to determine the optimum formulation of surimi products containing rice flour by using response surface methodology.
Nemipterus virgatus
) surimi (grade A; Khan Hoang Seaprex Co., Ltd., Soc Trang, Vietnam) was used in this study. (This surimi contained the usual cryoprotectants (e.g., sucrose, sorbitol, sodium polyphosphate, and sodium pyrophosphate)). Randomly selected surimi blocks (10 kg) were cut into 1 kg portions and kept at -20°C until further use. Rice flour (roll-mill, 80 mesh) was purchased from Daesun Flour Mills Co., Ltd. (Hampyeong, Korea). The other ingredients (Table
1
) were provided from Hansung Enterprise Co., Ltd. (Seongnam, Korea).

factorial points, 4 axial points (α = 1.414) and 3 center points. Rice flour content (
X

, %) and water content (
X
_{2}
, %) were chosen as the independent variables (IVs). The range and center point values of the two IVs were based on the results of preliminary experiments (Table
2
). Commonly, the minimum content of wheat flour was 5% in the commercial surimi products. In addition, when the rice flour added more than 15%, the prototype surimi products was not forming gel. Therefore, we chose the range of rice flour content from 5% to 15%. Gel strength (

,g∙cm) and overall acceptance (
Y
_{2}
) were selected as the dependent variables (DVs) for the different combinations of IVs (Table
3
). To minimize the effects of unexpected variability in the observed responses, the experimental runs were randomized.

P

were 11.62 and 2.91, respectively, and the related

increased. However, when
X

increased from 7 % (-1.414) to 14 % (+1.414),
Y
_{1}
and
Y
_{2}
were decreased. In a study by Chen et al. (Isa et al.,
1993
), starch addition up to 8% increased gel strength while lowering the expressible moisture value. This result is similar to our result where we show that the gel strength and moisture values have an inverse relationship. In addition, in a previous study, we suggested that an effective amount of rice flour to add was 10-15% (Cho et al.,
2013
). This result supported that rice flour content up to 15% increased gel strength and overall acceptance. As the coded values of IVs
X
_{1}
and
X
_{2}
were reached 13.5% (+1) and 9.25% (-0.5), respectively,
Y
_{1}
(gel strength) and
Y
_{2}
(overall acceptance) were increased. Generally, 4-12% of starch or wheat flour is added to surimi product (Park,
2005b
). However, up to 20-26% has been used for reducing the cost of surimi products (Hunt et al.,
2009
;Shim et al.,
2012
). Therefore, we suggest that rice flour can be more useful than wheat flour for reducing the costs of premium surimi products.

), which are shown in Table
7
. According to the canonical analysis of the response surface regression procedure, the eigenvalues of
Y
_{1}
was positive and the eigenvalue of
Y
_{2}
was negative. Therefore, the stationary points were target values. To obtain the optimal proportion of rice and water in surimi products, each target value,
Y
_{1}
(gel strength) and
Y
_{2}
(overall acceptance), were considered as a parameter during the optimization. The multiple optimal conditions (coded and actual values) of
X
_{1}
(rice flour content) and
X
_{2}
(water content) were 1.15 (14 %) and -0.55 (9.1 %), respectively. It has been reported that starch increases the gel strength of surimi products at lower concentration of 3% instead of higher concentrations of 6-10% (Yoon et al.,
1997
). In contrast, our results with rice flour show the opposite trend. It is considered that the gel strength was dependent on the inherent properties of starch and other ingredients used in the surimi product formulation (Hunt et al.,
2009
). The predicted values of
Y
_{1}
(gel strength),
Y
_{2}
(overall acceptance) at optimal conditions were 656.4 g∙cm and 6.34, respectively, and under optimal conditions, the experimental values were similar to the predicted values of
Y
_{1}
and
Y
_{2}
(647.8 g∙cm and 6.21, respectively). Therefore, the estimated response surface model was adapted for optimization of rice flour content in surimi products. Surimi products produced under optimum conditions were similar in strength to the gel strength of commercial products. However, its sensory evaluation score was higher than that of commercial products (Fig.
3
). In particular, typical fishy smell, which is a major cause of evasion of surimi product (Lee and Lee,
2002
), was reduced by adding rice flour. Therefore, rice flour enhances the quality of surimi products and is considered a valuable ingredient in the preparation of premium surimi products

Introduction

Surimi (or fish paste) products are the most representative processed fishery foods. They are widely used because their cooking is simple and inexpensive. In addition, surimi products can easily change the shape, taste, and texture of the final product as per consumer preferences (Kim et al.,
2005
). In South Korea, the most popular surimi product is the fried type, which is traditionally mixed with vegetables (Park,
2005a
;Choi et al.,
2012
). Currently, most surimi products are prepared using starch or wheat flour as an ingredient. Unfortunately, the price of wheat flour has increased and consumers were required high-quality products. Therefore, there is a need to come up with a cheaper alternative to replace wheat flour. Recently, rice flour was highlighted as a possible alternative to wheat flour (We et al.,
2011
).
Rice is the major staple crop of nearly half of the world’s population, and is particularly important in Asia, where approximately 90% of the world’s rice is produced and consumed (Zeigler and Barclay,
2008
;Khush,
2004
;Lee,
2012
). However, rice consumption in South Korea has decreased sharply owing to westernization of diet and increasing popularity of instant foods (Cha,
2010
;Statistics Korea,
2011
). Most rice are consumed after simple cooking and therefore the South Korean food industry is exploring the use of rice in new foods, both for domestic consumption and for export purposes (Shin,
2009
). The rheological properties and manufacturing process of surimi products containing different starches or functional powders, such as potato (Yang and Park,
1998
;Tabilo-Munizaga and Barbosa-Canovas,
2005
;Chung and Lee,

), waxy corn (Alvarez et al.,
1997
), wheat (Kong et al.,
1999
), red ginseng (Shim et al.,

),

- Preparation of the surimi product containing rice flour

Frozen surimi was partially thawed for 1 h at room temperature, to allow the core temperature to reach approximately -5°C. The thawed surimi was then cut into cubes (5 × 5 × 5 cm) and placed in a chopping bowl. The sample was chopped further at 1500 rpm for 5 min by a silent cutter (OMF-500, Ohmichi Co., Ltd., Maebashi, Japan). Two percent salt was added and the sample chopped for another 5 min at 1500 rpm. Rice flour was added slowly until homogenization of the mixture. The other ingredients were then added to the homogenized mixture according to the amounts listed in Table
1
and mixed for 3 min by the silent cutter. The formulation of Table
1
was selected because it is a general combination of ingredient for the production of commercial surimi products. During the chopping and mixing procedure, the temperature was maintained at approximately 5°C by crushed ice bath. After molding of the mixture, it was fried in soybean oil for 3 min at 150°C. All samples were then vacuum-packed and stored at 4°C.
- Determination of gel strength

Breaking force and deformation of the surimi product was measured by a puncture test using a TA-XT2 texture analyzer (Stable Micro Systems, Surrey, UK) equipped with a 0.25-inch spherical stainless probe. When the gel sample lost its strength and ruptured at a crosshead speed of 1.0 mm/s, the breaking force and depth of depression were recorded. Ten cylindrical samples with a length of 2.5 cm were subjected to the test. Gel strength was calculated using the following formula:
$${\mathrm{Gel}}\hspace{0.33em}{\mathrm{strength}}\hspace{0.33em}{\mathrm{(}}{\mathrm{g}}{\mathrm{.}}{\mathrm{cm}}{\mathrm{)}}\mathrm{{=}}{\mathrm{breaking}}\hspace{0.33em}{\mathrm{force}}{\mathrm{(}}{\mathrm{g}}{\mathrm{)}}\mathrm{\times}{\mathrm{depth}}\hspace{0.33em}{\mathrm{of}}\hspace{0.33em}{\mathrm{depression}}{\mathrm{(}}{\mathrm{cm}}{\mathrm{).}}$$

- Sensory evaluation

A trained panel comprising 20 members of the Korea Food Research Institute determined the organoleptic characteristics of the sample. The outward appearance, color, flavor, taste, chewiness, hardness, and overall acceptance were evaluated by a 7-point Likert scale (1 = extremely dissatisfied, 7 = extremely satisfied).
- Experimental design

Central composite design (CCD) (Box and Wilson,
1951
) was adopted in the optimization of rice flour and water content proportions in surimi products (Fig.
1
). CCD matrix consists of 2

- Diagnostic checking of the fitted models

Response surface methodology (RSM) is a useful statistical technique that has been applied to optimize formulations in various food products (Murphy et al.,
2004
). This methodology reduces the number of experimental runs required to generate sufficient information in order to provide a statistically acceptable result (Fogaça et al.,
2013
). The response surface regression procedure was employed to fit the quadratic polynomial equation to the experimental data. All the coefficients of linear (
