  • The purpose of this study was to investigate the antioxidative effects of Opuntia humifusa and determine the optimal mixing ratio of Opuntia humifusa powder and eggs for the preparation of pasta. In regard to its antioxidant effects, Opuntia humifusa powder had a total phenolic content and DPPH free radical scavenging activity of 6.64 mg/g and 90.12%, respectively. We used response surface methodology to obtain ten experimental points (including two replicates for Opuntia humifusa powder and egg) and Opuntia humifusa pasta formulation was optimized using rheology. Yellowness (p<0.001) displayed a linear model pattern, whereas lightness (p<0.01) and redness (p<0.01) were described by a quadratic model pattern. Mechanical properties showed significant values in hardness (p<0.5), chewiness (p<0.5), gummiess (p<0.5), and cohesiveness (p<0.5). The sensory evaluation parameters showed significant differences in color (p<0.5), appearance (p<0.5), flavor (p<0.5), texture (p<0.5) and overall quality (p<0.5). The optimum formulations processed by numerical and graphical optimization were found to be 7.30 g of Opuntia humifusa powder and 31.55 g of egg.

  • The present study was carried out to investigate the biological activity of ethanol extracts from fermented Opuntia humifusa with 3 different mushroom mycelia: Phellinus linteus, Lentinula edodes, and Pleurotus ostreatus. Fermented Opuntia humifusa by Phellinus linteus (FOP) and Lentinula edodes (FOL) showed more DPPH and ABTS radical scavenging activities than non-fermented Opuntia humifusa (NFO) and fermented Opuntia humifusa by Pleurotus ostreatus (FOPO). At a concentration of 250 ppm, the ABTS radical scavenging activities of the FOP and FOL were similar to that of BHA, a synthetic antioxidant. The total polyphenol content had a similar tendency to that of the radical scavenging activity. However, the flavonoid content was increased in the order of NFO, FOL, FOPO, and FOP. At all concentrations, the tyrosinase inhibitory activity of FOP and FOPO were significantly higher than that of kojic acid. During adipocyte differentiation, NFO and FOL showed no significant difference in lipid accumulation in 3T3-L1 cells. FOP and FOPO showed a higher fat accumulation inhibitory effect than NFO and FOL. These results provide baseline data for Opuntia humifusa as a novel functional food.

  • This study was undertaken to investigate the effect of Opuntia humifusa on the improvement of quality properties of Korean Jeolpyun. Chemical and mechanical properties of unsupplemented Jeolpyun and Jeolpyun supplemented with 1%-4% O. humifusa. Also, a sensory evaluation by a trained panel was conducted. Concerning color difference, the L value decreased, but a and b values increased as O. humifusa content increased. Texture analysis revealed that hardness, cohesiveness and adhesiveness were the highest in the unsupplemented control group. The texture parameters decreased as the O. humifusa addition ratio increased. In sensory evaluation, color and taste scores were highest score in 2% O. humifusa supplemented samples, with no difference in flavor being evident. Chewiness and adhesiveness scores were highest score in 4%-supplemented O. humifusa samples. Overall quality score was highest in the 2% O. humifusa samples. The addition of $2{\sim}3%$ O. humifusa optimizes Korean Jeolpyun.

  • Postmenopausal women are at an increased risk of developing coronary artery disease, primarily due to dyslipidemia that accompanies the loss of estrogen secretion. This study was performed to investigate the effects of Opuntia humifusa seed extracts on blood flow and serum lipid level in ovariectomized rats. Twenty-eight 9-week old female Sprague-Dawley rats were randomly assigned to four groups as sham-operated rats (SHAM), ovariectomized rats (OVX-CON), and ovariectomized rats that were treated with Opuntia humifusa seed extracts (OVX-OHS 2% and OVX-OHS 6%). The diets were fed to the rats for 7 weeks after operation. Serum total cholesterol and triglyceride contents decreased in the SHAM group compared to the OVX-CON group. Seven weeks of feeding of Opuntia humifusa seed extracts resulted in significant (p<0.05) lowering of serum triglyceride and a decreasing tendency in total cholesterol levels. The level of HDL-cholesterol in serum increased significantly by feeding diets containing the 2% and 6% Opuntia humifusa seed hot-water extract (p<0.05). Blood passage times were shorter in the Opuntia humifusa seed extract-supplemented groups than in the untreated group (OVX-CON). The platelet aggregation ability was lower in groups treated with Opuntia humifusa seed extracts than in the OVX-CON group. These results suggest that Opuntia humifusa seed extracts may have benefits in improving metabolic syndrome in menopausal women.

  • The taxonomic status of a new forma, Opuntia humifusa (Raf.) Raf. f. jeollaensis E. J. Kim & S. S. Whang, and the taxonomic relationships of three Korean cladodes were studied based on DNA sequences of three genes. The new forma O. humifusa f. jeollaensis (Wanggasi-Chunnyuncho) is simlilar to O. humifusa (Chunnyuncho), but differ in having both flower with the reddish inner center, and strong and many 3 cm long spines. Molecular studies showed that the new forma grouped into Macrocentra series instead of Humifusa series which included Korean O. humifusa. We designated the new taxa firstly studied here as a new forma, because the taxa have been mainly cultivated in farmlands in Jeolla-do area rather than distributed in nature. The taxonomic relationships of three Korean cladodes are discussed in detail.

  • The objective of this study was to determine the optimum mixing ratio of Opuntia humifusa powder and sugar in the preparation of muffin. The optimal sensory composite recipe was determined by following the central composites for muffin with different levels of Opuntia humifusa powder (A) and sugar (B). The analysis was performed using the response surface methodology, and the sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. The compositional and functional properties were measured, and the physical and sensory values were applied to the mathematical models. Perturbation plots showed the effects of each ingredient on the final product. Measurements showed significant values in lightness (p<0.05), sweetness (p<0.05), hardness (p<0.05), gumminess (p<0.05) and cohesiveness (p<0.01). The sensory measurements showed significant values in color (p<0.05), flavor (p<0.05), appearance (p<0.05), softness (p<0.05) and overall quality (p<0.05). Based on the numerical and graphical methods, the optimal formulation was determined to be 6.10 g of Opuntia humifusa powder and 82.61 g of sugar.

  • Purpose: Opuntia Humifusa has been used in the food and beauty industry after removing spines and glochids clearly. This study compared the methods used in removing spines and analyzed the design factors for developing a spine removal device. Method: This study compared the spine removal ratios in accordance with the length of brush, water spray pressure, the number of water spray, and the size of Opuntia Humifusa in a rotating brush device and a water spray device. In addition, this study compared the reversal ratios according to the inclination angle of a conveyor, the drop height of Opuntia Humifusa, and the speed of the conveyor to analyze the reversal factors. Results: The spines were not removed clearly in the rotating brush method, and the glochids were nailed deeply. The spine removal ratio was 96.9% with the water spray pressure of 20 $kgf/cm^2$ and the conveyor speed of 10 cm/s in the water spray method. The number of water spray was correlated with the spine removal ratio, and the average spine removal ratio was 95.6% with three cycles of water spray. The reversal ratio was 97% with the inclination angle of the conveyor $20^{\circ}$, the drop height of 380 mm, and the conveyor speed of 10 cm/s. Conclusions: In order to develop a Opuntia humifusa spine removing device, this study compared the rotating brush and water spray methods. As a result, each spine removal performance of the rotating brush and water spray methods was 96.9% and 95.6%, respectively. Although the performance of the rotating brush method was slightly higher than that of the water spray method, the water spray method was suitable for removing spines from stem because the epidermis of stem was damaged and the glochids were nail deeply in the rotating brush method. Further studies on appropriate arrangement of spray nozzles, maintaining the optimal water spray pressure, the speed and angle control of the feeding conveyor, and devices for inducing the stem to the center will be needed in combining the water spray device and the reversal device.

  • Opuntia humifusa, member of the Cactaceae family, was previously demonstrated to have radical scavenging, anti-inflammatory and anti-proliferative effects in in vitro models. It was suggested that O. humifusa could function in the prevention of carcinogenesis. To investigate the in vivo chemopreventive effect of O. humifusa, mice were fed a diet containing either 1% or 3% following 7, 12-dimethylbenz[a] anthracene (DMBA) and 12-O-tetradecanoylphorbol-13-acetate (TPA) induction of skin carcinogenesis. Significant decrease in the numbers of papilloma and epidermal hyperplasia were observed in mice fed with O. humifusa, compared to the control group. O. humifusa also upregulated high total antioxidant capacity and level of phase II detoxifying enzyme such as superoxide dismutase and glutathione S-transferase activity in the skin. Lipid peroxidation activity level was measured in skin cytosol and significantly inhibited in 3% OH fed group compared to the control group. These results suggest that O. humifusa exerts chemopreventive effects on chemical carcinogenesis in mouse skin and that prevention effects are associated with reduction of oxidative stress via the modulation of cutaneous lipid peroxidation, enhancing of total antioxidant capacity especially in phase II detoxifying enzyme system and partial apoptotic influence.

  • This study was conducted to identify the optimal mixing ratios of pomegranate powder or Opuntia humifusa powder for the production of jelly. To establish the amount of pomegranate powder or Opuntia humifusa powder that could be added to jelly, physicochemical sensory characteristics and textural properties were measured. Specifically, jellies were prepared using gelatin that contained a ratio of 0.5, 1, 1.5 and 2%(w/w) pomegranate powder or Opuntia humifusa powder. Sensory evaluation of the sweetness, chewiness, springiness, hardness, transparency and overall acceptability of jelly prepared using 0.5% pomegranate powder resulted in a high score. Similarly, the appearance, sweetness, chewiness, springiness, hardness, transparency and overall acceptability of jelly prepared using 0.5% Opuntia humifusa powder received a high score. Taken together, the results of this study suggest that pomegranate and Opuntia humifusa can be useful in the production of high quality jelly.
