  • This study examined carcass and meat quality parameters in growing/finishing pigs fed unconventionally versus the concentrate-based system. Ninety-six, 12 wk old pigs ($34{\pm}SD0.3kg$) were randomly divided into three groups, assigned to one of the three dietary treatments: standard complete concentrate mixture, conventional (C diet); unconventional, steamed potato-green forage-concentrate based diet (U diet), and unconventional basal diet+herbage mix (UH diet). Pigs fed U diet showed lower dressing percentage, meatiness, loin eye area, and weight of pork neck ($p{\leq}0.05$), but their carcasses were significantly ($p{\leq}0.05$) longer and had increased backfat depth ($p{\leq}0.05$). There was no impact of the diet on the meat content of dry matter, crude ash, acidity, and colour parameters of m. longissimus. Unconventional feeding significantly ($p{\leq}0.05$) elevated water the holding capacity of m. longissimus and slightly improved the sensory attributes analysis of meat. The addition of herbs resulted in increased loin eye area ($p{\leq}0.05$), decreased fat content ($p{\leq}0.05$) in m. longissimus, and tended to improve some sensory attributes of meat. There were significant gender differences in response to all diets. There were significant diet${\times}$sex interactions for some measured variables, but there were no clearly identifiable trends with regard to any specific carcass or meat parameters. Feeding unconventional diet to pigs may offer better culinary attributes of the meat, and improve some technologically important characteristics of pig carcass, but may negatively affect some carcass or meat parameters.

  • To evaluate the methanol extract from Pinus strobus leave as a possible ingredient of health food, the sensory analysis and an animal experiment were designed using cookie, candy or chewing gum containing the methanol extract. Cookie, candy and chewing gum which contained 0.4%, 0.25% and 0.3% of the methanol extract, respectively, were prepared by Haitai Confectionary CO.. Sensory analysis of the products was evaluated by hedonic scale. Our results indicated that the addition of the methanol extract to the products provides better sensory perception in hedonic score and higher preference number than control, especially in candy and cookie. In the animal experiment, the chickens fed diet containing 10% of the cookie powder for 2 weeks exhibited a reduction of the serum cholesterol level by 18%, compared with the chickens fed basal diet. This result suggested that the methanol extract from P. strobus leave contained a potential ingredient to reduce the concentration of serum cholesterol. Therefore, extract from Pinus strobus leaves can be used as an ingredient of health food.

  • The experiments was conducted to investigate the effects of dietary supplementation of feather meal and pyridoxine on the taurine content of egg yolk and performance of laying hens. Feeding trial was conducted with 900 31-wk-old Hy-Line Brown layers for 4wks. The experiment consisted of six dietary treatments: control(basal diet), feather meal(FM) 3 % diet(FM 3 %), FM 3 % + pyridoxine supplemented diet(FM 3 % + Pyridox), FM 6 % diet, FM 6 % + pyridoxine supplemented diet(FM 6% + Pyridox), Synthetic taurine 0.25 % supplemented diet(Taurine). Egg production of birds fed FM 3% was highest and those of the FM diets were also higher than those of Taurine and the control. Egg weight of Taurine was significantly lower than those of FM 3 %, FM 6 % and the control but were not significantly different from those of FM 3 % + Pyridox or FM 6 % + Pyridox. Feed intake of the control was greater than those of FM 6 %, FM 6% + Pyridox or Taurine treatment but was not significantly different from those of FM 3 % and FM 3 % + Pyridox. Feed conversion of the control was significantly higher than other treatments in which that of FM 6 % was lowest. Broken and soft egg production of Taurine was highest while that of the control was lowest among treatments. Taurine content of egg yolk significantly increased by supplementation of taurine(64.7 %). FM 6 % + pyridoxine(57 %), FM 3% + pyridoxine (32.1%) and FM 6% (16.6 %). Sensory evaluation data of Taurine has shown the highest score in most of sensory attributes. It is concluded that taurine can be enriched in egg yolk by supplementation of 6 % FM diet and pyridoxine as well as 0.25 % synthetic taurine.

  • To elucidate the relationship between the arachidonic acid (AA) content and the taste of broiler meat, the effects of AA-enriched oil (AAO) supplements on the fatty acid content and sensory perceptions of thigh meat were evaluated. Four types of oil, including corn oil (CO), a 1:1 mixture of AAO and palm oil (PO) (1/2 AAO), a 1:3 mixture of AAO and PO (1/4 AAO), and a 1:7 mixture of AAO and PO (1/8 AAO) were prepared. Each type of oil was mixed with silicate at a ratio of 7:3, and added to the diet at a final proportion of 5% of fresh matter. Broiler chickens were fed these diets for 1 wk before slaughter. In thigh meat, the AA content of the 1/2 and 1/4 AAO groups was significantly higher than that of the CO group. The AA content in thigh meat (y, mg/g) increased linearly with increasing dietary AAO content (x, g/100 g of diet), according to the equation y = 0.5674+0.4596x ($r^2$ = 0.8454). The content of other fatty acids was not significantly different among the 4 diet groups. Sensory evaluation showed that the flavor intensity, umami (L-glutamate taste), kokumi (continuity, mouthfulness, and thickness), and aftertaste of the 1/2 and 1/4 AAO groups were significantly higher than that of the CO group. There were significant positive correlations between AA content in thigh meat and the flavor intensity, total taste intensity, umami, and aftertaste. These data suggest that the taste of broiler meat can be improved by the amount of dietary AA supplementation.

  • This study was performed to provide basic for predicting the usefulness of Gastrodiae rhizoma(Cho'nma) as a food material for oriental applied diet therapy(YackSun). Thus, Gastrodiae rhizoma was used to develop a traditional Korean snack, Dasik. As a useful food resource, Gastrodiae rhizoma along with Cortex fraxini powder, was used to prepare Dasik. Cho'nma powder was added to the Dasik 63.2%(Dasik-1), 42.2%(Dasik-2) and 21.0%(Dasik-5) of Cho'nma powder to Dasik in one piece(5 g). The moisture and crude ash contents of the Dasik-1, 2 and 3 were analyzed. Physio-chemical analysis and a sensory test were also performed on the Dasik. Moisture and crude ash contents of Dasik-1 were 20.16% and 0.65%, respectively. Moisture and crude ash contents of Dasik-2 and Dasik-3 were 22.92 and 27.17% and 0.49 and 0.23% respectively. from the color test, the t value of Dasik-1 was found to be significantly low but the b value of Dasik-1 significantly high compared with the other preparations. The addition of Cho'nma had a tendency to impart high hardness, fracturability, gumminess and chewiness. Therefore, the addition of Cho'nma made the texture of Dasik denser. From the sensory test, the color, chewiness and overall acceptability of Dasik-1 were found to be significantly high. In conclusion, the addition of 63.2% Cho'nma per piece would be a useful recipe to enhance the quality of Dasik, and the flour Cho'nma showed better result than the Dasik-2 and Dasik-3.

  • The influence of supplementing diets with various levels of organic zinc (OZ) on the performance, meat quality attributes, and sensory properties of broiler chickens was investigated. A total of 3,200 1-d-old female broiler chicks were randomly allotted to 16 floor pens (replicates) with 200 birds per pen. A corn-wheat-soybean meal basal diet (control) was formulated and 20 ppm OZ (20 OZ), 40 ppm OZ (40 OZ), or 80 ppm OZ (80 OZ) was added to the basal diet to form four dietary treatments with four replicates per treatment. Live performance of broiler chickens, meat quality, and sensory properties were evaluated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p<0.05) in thigh skin epidermis and dermis thickness were shown in the OZ supplementation groups; however, no effect of OZ on the thickness of back skin epidermis or dermis was found. Dietary OZ levels did not affect the pH of breast and thigh meat or the water holding capacity (WHC) of thigh meat, but the WHC of breast meat increased significantly (p<0.05) when birds were fed 40 OZ and 80 OZ. Results of a sensory analysis showed no differences among the dietary treatments. In conclusion, dietary OZ did not affect live performance or sensory properties of broiler chickens but did increase the WHC of breast meat and thickness of skin layers; thus, improving carcass quality in broiler chickens.

  • Objective : The purpose of this study was to identify effects of intensive sensory integration (SI) treatment and home-program for a child who has a sensory integration disorder. This study also examined whether the positive effect is long-lasting by a follow-up test. Method : A boy with sensory integration dysfunction underwent an intensive SI treatment for 2 weeks. The intervention was consisted of 9 sessions and duration of the each session was 40 minutes. Sensory diet and Wilbarger protocol was provided as home program. The child's sensory function was evaluated before and after the SI intervention. Five month later, re-evaluation was executed for follow-up purpose. Results : In the evaluation after the Si intervention, the child's sensory defensiveness was decreased. Praxis, visual perception, sensory regulation dysfunction (sleep function), affective stabilization and performance of activities of daily living are also improved. In the re-evaluation after the 5 month later, the self-regulation ability, especially sleep function, has been maintained and the visual perception was developing continually. However, the child showed some affective regulation such as bothering his mother and losing his temper. Conclusions : The intensive SI intervention showed positive effects in terms of SI function improvement and the effect lasted long without any additional therapeutic intervention.

  • A total of 120 pigs (Berkshire) were used to investigate the effect of dietary supplementation with artificial culture medium ot wild ginseng (CMWG) on the fatty acid composition, amino acid composition and sensory characteristics or pork About $60{\pm}3kg$ pigs were randomly assigned to one of four experimental diet groups[(both sexes)${\times}$(C: commercial diet feed; T: commercial diet+1 L CMWG per day for 70 days)]. Pigs were slaughtered at approximately 110 kg live weight, and fatty acid composition, amino acid composition and sensory characteristics were measured in pork loin. The monounsaturated and saturated fatty acid contents was greater in barrow fed a diet containing CMWG than those of the gilt pork and control groups, however the polyunsaturated fatty acid composition decreased. The EAA (essential amino acid) content was lower in pigs fed diets containing CMWG than that of the control groups, whereas the SAA (amino acid with sulfide) and FRAA (fragrant amino acid) contents were higher. The EAA and FAA (amino acid in relation to flavor) contents were lower for harrow than for gilt, however the SAAA (amino acid in relation to saccarinity), SAA and FRAA the contents were higher. Regarding the sensory evaluation of fresh meat, the color of gilt pork increased with diets containing CMWG relative to the control group. Drip loss and the marbling score for pigs fed with diets containing CMWG were higher in barrow than in gilt. The flavor and overall acceptability of cooked meat from the control group was higher for barrow than for silt.

  • Objective: This study aimed to evaluate and compare the effects of three different diets on the fatty acids (FA) profile and sensory properties of a characteristic Italian fresh cheese: Pecorino "Primo Sale" (PS). Methods: Fifty-four sheep were divided into three feeding groups: total mixed ration (TMR) enriched with extruded linseed (TL), control diet with TMR without any integration (TC), and pasture (P). During cheese production, six cheeses per experimental group were produced each week, stored for 10 days at 4℃, and then analyzed for chemical composition, FA profile, and sensory properties. Results: Saturated fatty acids (SFA) were significantly higher in PS from group TC (82.11%) than in cheese from other two groups (P 75.48% and TL 66.83%). TL and P groups presented higher values of polyunsaturated fatty acids, 4.35 and 3.65%, respectively, than that of TC group (2.31%). The lowest SFA/unsaturated fatty acid ratio was found in TL and P groups, while the highest was found in the TC group. Vaccenic acid and conjugated linoleic acid (CLA) were higher in group P (p<0.05) than in groups L and TC. Sensory properties of cheese from group P received the highest scores for odor intensity and friability, while control group had a greater chewing consistency. Overall, all cheeses received good scores for acceptability. Conclusion: In conclusion, this study showed how the integration of extruded linseed improved the FA profile of fresh pecorino cheese PS preserving its sensory properties. Levels of CLA in the PS group achieved using this approach was not higher than that in a grazing diet. Cheeses from groups P and L contained a higher value of FA, with nutritional implications for humans, when compared with un-supplemented diet. Linseed may be a good feeding strategy when pasture is not available.
