This study sought to develop a healthier type of jeungpyeon, or Korean rice cake, by adding Korean black raspberry powder (Rubus coreanus). The moisture content, color, volume, symmetry, uniformity, texture, and sensory quality characteristics were evaluated in order to determine the optimal amount of raspberry powder to add to rice flour in order to get the best-tasting, healthiest food. We substituted 0.5%, 1.0%, 1.5% and 2.0% of rice flour with Rubus coreanus powder and mixed 3%, 6%, 9% and 12% Rubus coreanus concentrate with water to make dough. The result was stored for up to 48 hours at $20^{\circ}C$, and then evaluated. Jeungpyun with Rubus coreanus powder and Rubus coreanus concentrate had the right flavor, color, fermentation, and taste, compared to the other groups. Consequently, in overall acceptability, the highly rated Rubus coreanus powder-PW(1.5%) and Rubus coreanus concentrate - BA (6%) will be the most desirable.

The purpose of this study was to find new applications for Rubus coreanus and to produce new products. Jelly prepared with Rubus coreanus was studied and analyzed with regard to its composition, rheology and sensory evaluation. The technique of response surface methodology was used to analyze the results, which showed 16 experimental points including 2 replicates for Rubus coreanus juice, gelatin and sucrose. Rheological characteristics such as lightness, redness, yellowness and hardness, springness, chewiness and gumminess were shown to be significant, and these were mostly influenced by the content of Rubus coreanus juice. Significant sensory characteristics such as color, flavor, transparency, taste and the overall quality were also found to be greatly influenced by Rubus coreanus juice and gelatin in general. Based on the overlapping categories of factors that satisfied all sensory categories, the maximally optimized point was taken as the middle point. This value was determined to be 43.28 g of Rubus coreanus juice and 9.19 g of gelatin for every 140.00 g of sucrose.

Yukwa samples, made with additions of 0, 10, 20, and 30% Rubus coreanus Miquel extract, were puffed by different puffing methods(convection oven, microwave oven, and fryer) and were then examined for quality characteristics such as moisture content, expansion rate, color, hardness, and sensory qualities, in order to determine the optimal ratio of Rubus coreanus Miquel extract in the formulation and the optimal expansion of Yukwa. The moisture contents of Yukwa base increased as the level of Rubus coreanus Miquel extract increased. And the Yukwa puffed by convection had higher moisture than the samples puffed by microwave oven or frying, with the exception of the sample containing 20% Rubus coreanus Miquel extract. When comparing the expansion rates of samples, no significant differences were found between the control and extract-containing samples puffed by convection, microwave, and frying methods, respectively. However, the sample puffed by frying had the highest expansion rate, whereas the convection-, microwave-puffed samples showed no significant differences. In the convection-, microwave-, and fryer-puffed samples, lightness and yellowness decreased, but redness increased, as the level of Rubus coreanus Miquel extract increased. And the sample puffed by microwave oven had greater lightness as compared to the samples puffed by convection and frying. In terms of hardness, no significant differences were found the control and extract-containing samples puffed by convection and microwave methods. However, hardness was maximal in the sample puffed by convection and lowest in the sample puffed by frying, in which it increased according to the addition of Rubus coreanus Miquel extract. In the consumer acceptance evaluations and characteristics intensity rating tests, the samples puffed using convection and microwave methods showed higher scores for the majority of evaluated characteristics as compared to the samples puffed by frying. And the samples containing Rubus coreanus Miquel extract obtained fairly good scores. In conclusion, the results indicate that additions of 10$\sim$20% Rubus coreanus Miquel extract are optimal for Yukwa that is puffed by convection and microwave methods, as this range provides good physiological properties and reasonably high overall consumer acceptability.

Rubus coreanus Miquel (bokbunja), Korean black raspberry, is known to possess various phytochemicals that exert antioxidative, anti-inflammatory, and anti-cancer effects. However, most studies on Rubus coreanus Miquel have been performed with the solvent extracts and/or a single component to demonstrate the efficacy, while studies evaluating the effect of the whole fructus of Rubus coreanus Miquel are limited. In this study, therefore, we employed the isoproterenol (IPN)-induced myocardial infarction model and investigated the effect of freeze-dried powder of Rubus coreanus Miquel (RCP) on oxidative stress and prevention of organ damage. Oral administration of RCP reduced the level of toxicity markers, alanine transaminase (ALT), aspartate transaminase (AST), and lactate dehydrogenase (LDH) without affecting body weight and diet intake. The oxidative stress marker glutathione (GSH) increased about 45% and malonaldehyde (MDA) decreased about 27% compared to the IPN group with RCP-H (3%) administration. By histological analysis, IPN induced significant myocardial damage in the heart and vascular injury in the liver, and RCP administration ameliorated the damages in a dose-dependent manner. Taken together, RCP activated the antioxidant system leading to prevention of damage to organs by IPN in rats, making it possible to expect beneficial efficacies by consuming the whole fructus of Rubus coreanus Miquel.

The objective of this study is to investigate the optimal condition for macerating enzymatic extraction process that leads to the highest yield and the largest extracted amount of bio-active contents from Rubus coreanus Miq. fruit. The optimal extraction conditions were found as the following: The initial amount of the water added to the fruit was 20 ~ 30% by weight. The mixing ratio used for the macerating enzyme was 4 : 1 : 2 (w : w : w) for cellulase:pectinase:amylogucosidase, and the amount of the macerating enzyme added was 2% by weight. The extraction process was done at a temperature of $45{\sim}50^{\circ}C$ for 10 hours. The extraction yields on Rubus coreanus Miq. fruit by macerating enzymatic extraction process was increased by 84.3% compared to that of hot-water extraction process. The amounts of organic acids and vitamin found in the extract were also higher. The amount of polyphenol and anthocyanin contents in the extract were 185% and 257% of those from hot-water extraction, respectively. These results suggest that macerating enzymatic extraction is an effective method to boost extraction yield and to increase the amount of extraction of bio-active contents from Rubus coreanus Miq. fruit.
