This research studied the effects of Backryeoncho (Opuntia ficus-indica var. saboten) extract as an additive in kimchi in various amounts (0%, 0.4%, 0.8%, 1.2%), and its acceptance by middle school students in the Jeonju area. The treated kimchi had a higher pH than the untreated kimchi without extract, and the titratable acidity of the kimchi decreased with the addition of the Backryeoncho extract. The degree of salinity decreased in kimchi with the added Backryeoncho extract in a dose-dependent manner. The cutting force and compression force were higher in kimchi where the extract was added during the fermentation period resulting in improved texture of the kimchi. The addition of the extract slowed growth of total bacteria (1.83~2.12 log CFU/mL) and lactic acid bacteria (1.4 log CFU/mL) as compared with the control sample. In the sensory evaluation of overall taste, kimchi with 0.8% extract added demonstrated higher evaluation in overall categories. The acceptability of Backryeoncho extract as an additive in kimchi among middle school students was higher than in the control sample, with an optimum additive of 0.4% extract, based on the lowest volume of leftovers.

This study was aimed at evaluating a proper mixing ratio of making Beaknyuncho(Opuntia ficus-indica var. saboten) Sulgidduk with different types of extraction, a fruit and a stem of Beaknyuncho, and by different making methods. As a result, moisture content was the highest(43.22%) in FP1 and the lowest(38.55%) in SJ60. The low lightness and yellowness are increased with more powder and juice of both fruit and stem added. The mechanical characteristics, hardness, adhesiveness and gumminess were increased as powder and juice were added. And cohesiveness and springiness were decreased. The identification test showed that a sample containing stem juice was the most preferable for taste, chewiness, moistness and after-taste. The preference test showed that a sample containing stem juice was the most preferable for color, texture and overall quality and a sample containing stem powder was preferable for flavor and taste. Both SJ60 mixed with 60% Beaknyuncho stem juice and FP3 mixed with 3% fruit powder proved to be the most desirable in both sensory evaluation and texture characteristics.

This study was conducted to analyze the nutrient compositions of stem and fruit of Opuntia ficus-indica var. saboten (OF) and Opuntia humifusa (OH). The results of the two-way analysis of variance test indicated that the parts, varieties and parts*varieties had influence on nutrient content except crude protein, soluble dietary fiber, Fe, Se, I, vitamin E, niacin and vitamin C. Moisture and crude ash content was higher in stem than in fruit, while crude lipid and insoluble dietary content was higher in fruit than in stem. Mineral content revealed that K (1,313.67 mg% in OF, 1,351.38 mg% in OH) was the highest in fruit and Ca (5,146.29 mg% in OF, 1,388.19 mg% in OH) was the highest in stem. Vitamin C was the most abundant vitamin in the fruit of OF (199.98 mg%) and OH (187.12 mg%). Polyunsaturated fatty acid was the highest among fatty acids (66.9~70.1%), with higher content in the stem (753.89 mg%) than fruit (578.01 mg%) in OF, while higher in the fruit (1,093.63 mg%) than stem (475.07 mg%) in OH. Moisture, crude protein, Mg, Se and riboflavin was higher in OF than OH; whereas, crude lipid, insoluble dietary fiber, total dietary fiber and monounsaturated fatty acid were higher in OH than OF. These results indicated that OF and OH could be a good food source for Ca, K and Vitamin C. Also, different nutrient content by parts and varieties, can be helpful in choice of parts or varieties for consumer purposes.

Different amounts of the Opuntia ficus-indica var. saboten fruit were soaked in different alcohol concentrations of a Korean rice wine distillate for 4 months. Changes in pH, brix degree, contents of reducing sugar and polyphenol compound, alcohol concentration, turbidity, and color were analyzed during the soaking period. Quality of the final product was determined through the analysis of the volatile flavor compounds and sensory evaluation. During the soaking periods, pH, alcohol concentration, and contents of polyphenol compound decreased, whereas the content of reducing sugar increased. These changes were affected more by the content of the fruit than the alcohol concentration of the soaking media. Turbidity of the wine increased with higher fruit contents, while the increase of alcohol concentration resulted in the turbidity decrease. As the soaking period increased, lightness and yellowness increased but redness decreased. Acetaldehyde, acetyl acetone, ethyl alcohol, guaiacol, thymol, and acetic acid phenyl ester were detected in all liquors. Significant differences in all sensory attributes test were shown by six experimental groups (p<0.05), and the best overall acceptability was obtained from the liquor made of 67% fruits and 30% alcohol concentration.

The aim of this study was to evaluate the quality characteristics, antioxidant activities, and sensory properties of macaron with Opuntia ficus-indica var. saboten powder (OP). Physicochemical and sensory properties of macaron with different amounts (0%, 2%, 4%, and 6%) of OP were examined. The quality of macarons was evaluated based on spread factor, baking loss rate, color, texture, antioxidant activities, and sensory evaluation. As amount of OP addition increased, spread factor and a value increased, whereas baking loss rate, and L and b values decreased (p<0.05). For texture properties, hardness, springiness, and brittleness were lower as OP content increased while cohesiveness and gumminess were not significantly different (p<0.05). For total polyphenolic contents, DPPH and reducing power significantly increased upon addition of OP at high concentrations (p<0.05). In the sensory evaluation of macarons, scores for color, flavor, taste, texture, and overall acceptance were highest with 4% OP, whereas macaron containing 6% OP showed the lowest scores for taste and texture (p<0.05). These data suggest that addition of 4% OP is the optimal concentration for making macaron.

Oxidative stress caused by reactive oxygen species is ascribed to many neurodegenerative diseases like Alzheimer's disease. Phenolic antioxidants can reduce the oxidative stress. In this study, ripe fruits of Opuntia ficus-indica var. saboten (OFS) were extracted using 80% (v/v) aqueous ethanol. Total phenolic and flavonoid contents of the OFS fruits (100 g) were 409.9 mg gallic acid equivalents and 72.2 mg catechin equivalents, respectively. The OFS fruits had antioxidant capacity at 381.2, 298.2, and 3,219.9 mg vitamin C equivalents/100 g in ABTS, DPPH, and ORAC assays, respectively. The OFS fruits showed protective effects on PC-12 cells against oxidative stress in a dose-dependent manner, partly due to decrease of intracellular oxidative stress. Furthermore, the OFS fruits inhibited both acetylcholinesterase and butyrylcholinesterase. Consequently, these results suggest that the OFS fruits might be served as a source of functional materials to reduce oxidative stress in neuronal cells and to inhibit cholinesterases.

The fruit and stem of Opuntia ficus-indica var. aboten (OFS), a native plant of Jeju Island, are considered a safe food source. Moreover, stem extracts have been previously reported to possess a variety of biological effects (e.g. anti-inflammatory and anti-oxidant, including the ability to partially ameliorate cognitive impairment), suggesting that this plant may have utility as a functional food. The present study investigated whether fermentation by lactic acid bacteria enhances the biological effects of OFS extracts. The acetylcholinesterase (AChE) inhibitory activity of fermented or non-fermented OFS extracts was evaluated, and the content of marker components dihydrokaempferol (DHK) and quercetin-3-methyl ether (3-MeQ) was analyzed using high-performance liquid chromatography. Fermented (relative to non-fermented) OFS extracts exhibited improved AChE inhibitory activity ($IC_{50}=28.35 mg/mL$), with AChE inhibitory activity resulting from fermentation by L. plantarum ($IC_{50}=12.56mg/mL$) exceeding that resulting from fermentation by L. fermentum ($IC_{50}=17.71mg/mL$). Furthermore, fermented (relative to non-fermented) OFS extracts exhibited a 16.7 % increase in DHK content, and 3-MeQ content of OFS extracts fermented by L. plantarum and L. fermentum increased by 28.6 % and 21.4 %, respectively. Therefore, OFS stem extract AChE inhibitory activity, as well as DHK and 3-MeQ content, was enhanced by fermentation with Lactobacillus spp. This suggests that fermented OFS extracts may contribute to prevention or improvement of cognitive impairment. These data are anticipated to be useful in the development of enhanced-efficacy OFS products.

In this study, we assessed antioxidant, anti-diabetic, and anti-Alzheimer activities of Opuntia ficus-indica var. saboten (OFI) at harvest time. OFIs were cultivated December 2015~November 2016 in Jeju island. The 70% ethanol extracts of OFI were used to investigate total polyphenol and flavonoid contents, antioxidant(DPPH and ABTS radical scavenging assay), anti-diabetic(yeast ${\alpha}$-glucosidase and rat ${\alpha}$-glucosidase inhibition assay), and anti-Alzheimer(Acetylcholinesterase and butyrylcholinesterase inhibition assay) activities. Total polyphenol and flavonoid contents of OFIs were $17.40{\sim}23.11{\mu}g$ garlic acid/mg Ex and 2.17~6.22 ug (+)-catechine/mg Ex, respectively. DPPH and ABTS radical scavenging activity of OFIs were 131.98~184.90 mg ascorbic acid(AA) eq/100 g and 63.60~101.83 mg AA eq/100 g, respectively. In the anti-diabetic and anti-Alzheimer activities, 70% ethanol extracts of OFI exhibited moderate inhibition activity, compared to control (acarbose and beberine). Total polyphenol and flavonoid contents, antioxidant, anti-diabetic, and anti-Alzheimer activities were no significant differences by season, respectively. Therefore, information on comparative biological evaluations of OFI may be a beneficial in exploring functional food and drug development.
