  • The purpose of this study was to investigate the effects of adding various amounts of ingredients on the physicochemical and sensory characteristics of Bokbunja-jelly. The proximate composition of Bokbunja-jelly was 19.0% for the moisture and 0.8% for the crude protein. The Hunter L-values of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose were higher than that of Bokbunja-jelly prepared by adding 20 g RME or 100 g sucrose. The Hunter b-values of Bokbunja-jelly prepared by adding 20 g RME or 120 g sucrose was higher than that of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose. The hardness and chewiness were increased with decreasing Rubus coreanus Miquel extracts. According to the results of the sensory evaluation, no significant differences in flavor, sweetness, hardness, elasticity and overall qualities were found. According to the results of physicochemical properties and sensory evaluation, the optimal recipe for preparation of Bokbunja-jelly was determined to be 240 g water, 120 g sugar, 110 g glucose syrup, 4 g agar, 20 g Rubus coreanus Miquel extracts and 0.3 g Rubus coreanus Miquel flavor.

  • Five types of kiwi jelly were prepared with different rates of pressed kiwi juice and carrageenan, and their quality characteristics such as chemical composition, saccharinity, color, texture, and sensory attributes were measured. There were no significant changes in moisture, crude lipid, carbohydrate, but significant differences were shown in crude ash, crude protein, pH, and acidity. The pH decreased and acidity increased as the amount of added kiwi juice increased. The saccharinity of kiwi jelly increased with increased amount of added kiwi juice. Additionally, the total phenolic content, DPPH radical scavenging activity and content increased with increased amount of added kiwi juice. The hardness, gumminess, and chewiness increased with increased levels of carrageenan. As the amount of added carrageenan increased, the L values of kiwi jelly decreased. Based on the sensory evaluation test, kiwi jelly, JKJ(Jeju Kiwi Jelly)-3 was the best in the flavor, sweetness, texture, and overall acceptability. The chemical composition of JKJ-3 was as follows : moisture $75.1{\pm}0.5%$, carbohydrate $24.2{\pm}0.5%$, crude protein $0.29{\pm}0.05%$, and crude ash $0.44{\pm}0.02%$. The kiwi jelly, JKJ-3 of overall acceptability values in the sensory test for flavor, sweetness, hardness, texture and overall favorite were 3.65, 3.35, 3.35, 3.50 and 3.60, respectively, with the addition of 20% pressed kiwi juice and 2.3% carrageenan.

  • To prepare oriental melon jelly having highly favorite, oranoleptic and physical properties of jelly with special to the content of glucomannan, oriental melon concentration juice and vinegar was monitored by four-dimensional response surface methodology. Mouth-feel showed maximum sensory score in 0.09% glucomannan, 3.17% oriental melon concentration juice and 1.25% oriental melon vinegar. Organoleptic taste showed maximum sensory score in 0.12% glucomannan, 3.64% oriental melon concentration juice and 0.91% oriental melon vinegar. Overall palatability showed also maximum sensory score in 0.10% glucomannan, 3.07% oriental melon concentration juice and 1.34% oriental melon vinegar. The sensory socore of overall palatability was more than 7.0 in the texture ranges of 0.20~0.31 cm/g (softness) and 8.0~12.5 gㆍcm (jelly strength).

  • Changes in fish jelly forming ability of pretreated and frozen common carp and conger eel were examined. Four kinds of pretreated samples were prepared such as round, mechanically separated meat using fishmeat separator, chopped and water washed meat and fish meat paste. The quality of pretreated samples and fish jelly products made from pretreated sample were generally in good condition for three months of frozen storage at $-30^{\circ}C$. Judging from fish jelly forming ability, the round state of common carp was superior to other pretreated samples during frozen storage. In case of conger eel, fish meat paste revealed totter jelly forming ability than any other pretreated samples during frozen storage.

  • This study was carried out to investigate the physicochemical quality characteristics of Nouaejelly(jelly using silkworm powder) sericultural products which were manufactured using various levels(0.5, 1, 1.5 and 2%) of silkworm powder. The effects of an additional amount of silkworm powder to Nouaejelly were determined by examining, the physicochemical, sensory, and textural properties. The moisture and crude protein content of the Nouaejelly were higher than that of the control(p<0.05). However, the crude fat content of the Nouaejelly was lower than that of the control(p<0.05). The mineral content increased with increasing addition of silkworm powder. The color of the Nouaejelly became darker with increasing levels of silkworm powder. For the texture measurements, the hardness, gumminess and chewiness of the Nouaejelly decreased with increasing levels of silkworm powder, but those of the jelly were decreased significantly by adding 0.5% silkworm powder(p<0.05). In terms of color, the texture and overall preference of Nouaejelly was highest in the jelly containing 1 % silkworm powder(p<0.05). Overall, the optimal amount of silkworm powder added in the manufacture of Nouaejelly was 1% of the total weight.

  • The purpose of this study was to determine the optimal mixing conditions for different amounts of konjac(0.2, 0.3, 0.4, 0.5, 0.6%) and carrageenane(0.8, 1.0, 1.2, l.4, 1.6%) in the preparation of citrus jelly, using the central composite design. The results showed that the sensory and mechanical characteristics of the jelly increased with decreasing konjac and carrageenane contents. Overall optimal conditions that satisfied the rheology, appearance characteristics and sensory properties of the citrus jelly were 0.2% konjac, 1.2% carrageenane and 30minutes of heating time using citrus juice of $20^{\circ}C$Brix and 0.3% citric acid.

  • [Purpose] Sex hormones deficiency leads to dramatically bone loss in particular postmenopausal women. Royal jelly has anti-osteoporosis effect due to maintain bone volume in that condition. We hypothesized that royal jelly protein (RJP, a latent residue after extracting royal jelly) also prevents bone deficient in ovariectomized (OVX) female rats, the animal model of postmenopausal women. [Methods] Female Sprague-Dawley rats (n = 30, 6 weeks age old) were sham operated (Sham; sham operated group, n = 7), OVX control group (OC, n = 7), OVX with low RJP intake group (ORL, n = 8), and OVX with high RJP intake group (ORH, n = 8) during 8 weeks experimental periods. In the end point of this experiment, the bone samples (lumbar spine, tibia, and femur) were surgically removed under anesthesia. These bone samples were evaluated bone mineral density (BMD) and bone strength. [Results] BMD of lumbar spine in RJP intake groups (ORL, ORH) were higher than that in OC group (p < 0.05 and p < 0.01) in RJP intake volume dependent manner. BMD of tibial proximal metaphysis and diaphysis in RJP intake groups were also higher than these in OC group (p < 0.01 and p < 0.01 / p < 0.05 and p < 0.001). In addition, breaking force of femur in RJP intake groups were significantly increase compared with that in OC group (p < 0.001 respectively). [Conclusion] These findings indicate that RJP contribute to prevent sex hormone related bone abnormality.

  • The generation of waste cable has been continuously increased as a production of electrical and communication media are extended. The current recovery methods, such as mechanical peeling, incineration, solvent extraction and pyrolysis, seems inadequate because they are either hard to apply in some cases or environmentally unacceptable. It has been shown that copper can be effectively separated from the jelly filled type cables using a soybean oil treatment method. As a result, jelly compound is vanished from the wire by soybean oil bath and waste wires are separated copper and PE by the mechanical chipper. This is a more environmentally friendly method than burning, and considerably faster than Stripping.

  • Microcapsules were prepared by complex coacervation between gelatin and gum arabic. The object of this work is evaluation of the effect of jelly strength, hardening agent on the particle size distribution, surface morphology and DSC. It was found that the 300bloom jelly strength caused microcapsules' size larger. When the amount of hardening agent increased, the particle mean diameter was larger. The amount of hardening agent was determined to be 10m1 for getting suitable size to finish the fabric.
