The purpose of this study was to develop Zingiber officinale Roscoe powder(ginger powder) sweet rice muffins. The process included substituting sweet rice flour for cake flour and adding ginger powder. The mixing conditions for the ginger powder sweet rice muffins were a control and three levels of ginger powder (A), whole egg (B), and soybean oil (C) using central composite design, and were optimized by response surface methodology. The optimization was analyzed with regard to physical, textural, and sensory properties. Among the sensory properties, variables that appeared to show significant values, such as appearance, flavor, softness and overall quality were used to identify optimums. The numerical and graphical methods used in this study determined that the optimum formulation for ginger powder sweet rice muffins was 8.39 g of ginger powder, 215.37 g of whole egg, and 54.40 g of soybean oil. Ginger increases appetite, enhances metabolism and reduces the speed of aging. These health advantages of ginger provide evidences that ginger powder sweet rice muffins are a good healthy snack, particularly for the elderly.

The effects of tigernut dietary fiber (TDF: 5, 10, and 20% w/w) inclusion in rice muffin formulations on the functional and pasting properties of composite powders, as well as the nutritional and sensory properties of muffins were investigated. The results showed a significant (p<0.05) proportional increase in the water and oil holding capacity as TDF increased in the powder blends. Moreover, pasting viscosity was found to decrease with the inclusion of TDF. TDF muffins showed improved nutritional quality, with increased protein (~14%), insoluble fiber (~128%) and total fiber (~34%) contents compared to 100% rice muffins. Also, TDF-muffins had lower baking losses (~22%) and better texture, including firmness and chewiness. Sensory scores of TDF-muffins (up to 10% w/w) showed similar consumer acceptability for all parameters considered. Overall, this study suggests tigernut fiber as a functional additive that balances the growing consumers' demands for healthy and quality gluten-free rice muffins.

This study examined the effects of chestnut powder content (2.5%, 5%, 7.5%, and 10%) on the antioxidant activity and quality characteristics of rice muffins. With the increasing chestnut powder content, the total polyphenol content, flavonoid content, antioxidant activity (determined by radical scavenging activity and reducing power), hardness, gumminess, chewiness, and overall acceptability (determined by sensory evaluation) increased, whereas the moisture content, pH, specific volume, and cooking loss decreased. Regarding color, chestnut powder content was negatively correlated with L and b and positively correlated with a. Notably, overall acceptability abruptly decreased to its minimum at 10%. Thus, adding powder at loadings of <7.5% improved the antioxidant activity and acceptability of rice muffins. Our results can be used as preparatory data for developing a rice muffin model.

The purpose of this study was to develop a muffin recipe that included germinated brown rice powder soaked in a mycelial culture broth of Phellinus linteus (GBRP). Muffins were made using various quantities of GBRP, butter, and milk. An assessment was conducted using the response surface methodology (RSM), which included 16 experimental points with three replicates for the three independent variables: GBRP, butter, and milk. The physical and chemical evaluation using the RSM showed no significant differences; whereas the hardness, cohesiveness, springiness, gumminess, and chewiness indicated significant differences in the relationships between the factors (p<0.05). The sensory evaluation using the RSM was highly effective in describing the relationships between overall acceptability and taste (p<0.001). Thus, the optimal combination of ingredients in a GBRP muffin, as assessed with numerical and graphical methods, was 84.041 g GBRP, 110.224 g butter, and 80.0 g milk.

Background: The Korean government launched a project in 2008, where the amount of rice used as raw ingredient in rice-based foods in 2012 was planned to increase up to 10% (470,000 ton) of the total rice production through developing various new rice-based processed foods and their commercial manufacturing technology. Among the four major rice-based processed foods, rice cakes and noodles need rice flour as their main raw ingredient. Technology in rice flour utilization and manufacturing is far behind than the technology pertinent to wheat flour in many subject areas. Purpose: This review aims to provide information on rice flour utilization and manufacturing with some fundamental subjects in the area of size reduction. Results: A variety of food items including bread, noodle, cake, cookie, muffin, pre-mix, beverage, vinegar, surimi, and artificial meat have found rice flour as their raw ingredient. Rice bread made out of 100% rice flour has been developed and is now sold in retail stores. Various noodle products made from rice flour are also on the market. Issues on product definition and labeling regulation about rice flour content of the products were explored. Generalized grinding equations available in the literature were seldom used in practice; instead, it has been a general practice to develop empirical equations from test milling data. Introductory remarks on three popular particle size measurement methods (sieving, Coulter counter, light diffraction) were explained. Mathematical expressions frequently used to describe particle size distribution and to correlate cumulative quantity of particles with particle size were represented. Milling methods used in producing rice flour were described along with their advantages and disadvantages. Because of their profound effect on functional properties of the rice flour, four rice flour milling equipments used at both laboratory experiments and commercial manufacturing plants were discussed.

The purpose of this study was to promote the consumption of rice by substituting goami powder for flour when making muffins. Goami powder was prepared in different particle sizes by grinding the powder for 5 min. 10 min. 15 min. and 20 min. Precisely 72.62% of the goami powder, particles were smaller than 75 ${\mu}m$, after grinding the powder for 20 min. with a consistency similar to that of flour (78.86%). To determine the optimal amount of water for goami powder muffin batter, the viscosity of both the flour and the goami powder batter was measured. The appropriate water quantity for goami powder muffins was set at 105 mL. The volume index of flour muffins was 132 mL, while that of the goami powder muffin (GM1, GM2, GM3 and GM4) was 123 mL, 119 mL, 119 mL and 118 mL, respectively. The hardness of the flour muffins, measured by a texture analyer, was 2.03${\times}10^3$ g/$cm^2$, The hardnesses of the goami powder muffins were 2.83${\times}10^3$ g/$cm^2$ for GM1, 2.44${\times}10^3$ g/$cm^2$for GM2, 2.33${\times}10^3$ g/$cm^2$ for GM3, and 2.36${\times}10^3$ g/$cm^2$ for GM4. The L-values and moisture content of the goami powder muffins were higher than those of the flour muffins. In a sensory evaluation the overall preference was the highest for flour muffins. However among the goami powder muffins, GM3, which was made with goami powder ground for 15 min. was the most preferred.
