This study was conducted to investigate en the quality characteristics and palatability of beef patties containing various gums such as carrageenan, xanthan gum and guar gum. Moisture contents of raw and cooked patties of control were lower than those of the gum-added Patties, and fat content of control patty was higher than that of the gum-added patties. Protein content of gum-added patties was higher than that of the control patty. Hunter's $L^{*}$ value (lightness) of raw patty of control was higher than that of the gum-added patties, hut Hunter's $a^{*}$(redness) and $b^{*}$(yellowness) values were not different among four kinds of patties. Hunter's $L^{*}$, $a^{*}$ and $b^{*}$ values of cooked patties showed no significant difference among patties. Cooking yield, fat retention and water holding capacity of gum-added patties were higher than those of the control patty. Hardness and chewiness of patties showed no significant difference among patties, but gumminess of gum-added patties was higher than that of the control patty. Aroma, juiciness and palatability were not different among four kinds of patties, but texture of gum-added patties was higher than that of the control patty.l patty.tty.

본 시험은 냉동 및 해동 방식에 따른 토종오리 고기의 이화학적 특성을 조사하기 위해 수행하였다. 처리구는 8주령 오리육을 대조구(Control)로 하고 처리구는 냉동방식 2가지(급냉, $-50^{\circ}C$; 완냉, $-20^{\circ}C$)과 해동방식 2가지(완해동, $4^{\circ}C$ 냉장해동; 급해동, $13^{\circ}C$ 유수해동;의 $2{\times}2$ 복합요인으로 하여 총 5처리구, 처리구당 3반복, 반복당 3점(2수/점)으로 나누었다. 공시재료는 각 처리구에서 발생된 8주령 토종오리 수컷을 처리구당 18수씩 선별하여 도압하고 1개월간 저장 후 분석에 이용하였다. 명도는 완냉시키거나 완해동할 때에 대조구와 유의적인 차이가 있었으나(P<0.05), 적색도와 황색도는 처리구간 유의차가 없었다. 가열감량과 보수력은 급냉시키거나 급해동시킬 때 대조구에 비해 유의적으로 높게 나타났으나(P<0.05), 전단력은 대조구에 비해 낮게 나타났다(P<0.05). 가열감량, 전단력, 보수력은 냉동 처리구 사이에서는 유의적인 차이를 보이지 않았으나, 가열감량은 급해동과 완해동 사이에 유의차가 나타났다(P<0.05). 수분, 지방, 단백질, 조회분의 함량은 냉동 처리구와 대조구 사이에서 유의차가 없었으나, 수분함량은 급해동 처리구에서 완해동 처리구에 비해 유의적으로 높게 나타났으며(P<0.05), 단백질 함량은 완해동 처리구에서 대조구에 비해 높게 나타났으나(P<0.05) 해동 처리구간에는 유의적인 차이가 없었다. 지방과 단백질 함량은 해동 처리구 사이에서 유의적인 차이를 보이지 않았다. 결론적으로, 본 시험에서는 냉동과 해동 방식에 따른 오리고기의 특징을 보여주고 있으며, 이런 결과들은 토종오리 산업과 오리육 생산 산업에 큰 도움이 될 것이라 사료된다.

This study was performed in order to investigate the quality characteristics of sponge cake made with Laminaria japonia powder. To evaluate the physical and sensory analysis, Laminaria japonia powder was added to wheat flour in various ratio (3, 5, 7, 9%, w/w). The specific gravity and loss rate increased with the addition of Laminaria japonia powder. The crude protein and ash levels in the sponge cakes increased linearly with the addition of 0~9 g of Laminaria japonia powder/100 g of wheat flour. For the crumb color values, lightness (L) and yellowness (b) decreased with the addition of Laminaria japonia powder, whereas redness (a) significantly increased (P<0.05). In the texture analysis, the hardness, gumminess and chewiness were increased; however, the cohesiveness and resilience were reduced by the addition of Laminaria japonia powder. When the sensory characteristics were evaluated, 5% Laminaria japonia sponge cake showed the highest sensory properties, except for color. Therefore, the results suggested that 5% Laminaria japonia sponge cake could be helpful in improving the physical quality as well as the taste.

Coating with chitosan ($2\%$, pH: 5.0) had a beneficial effect such as less weight loss, flesh firmness and maintenance of sugar content of tomatoes stored at the normal temperature. The weight loss of chitosan-coated tomatoes was $4.8\%$ during the storage-period (18days) while that of control was $10.2\%$. When it was stored for 18 days, the tomatoes coated with chitosan showed higher in firmness (1.63 kg) and pectin content ($0,58g\%$) than the control (1.03 kg, $0.44g\%$). For the total soluble acid and pH, the tomatoes coated with chitosan were higher in oxalic acid ($0.17 g\%$) than the control ($0.15 g\%$) and the latter were higher in the pH than the former, when they were stored for 18 days.

This study evaluated the close crop recycling method by using the extract from defective onions. The mixture of the diluted extract (1/500) and nutrients was applied seven times on the onion leaves without spilling it onto the field. The yield and quality of the onions produced by this method (recycle) were compared to those grown organically (control) and conventionally (normal). The yield from the recycling field was increased significantly by 9% compared to that of the control field, while it was decreased by 11% compared to the normal field (p < 0.05). This lower yield was explained by the differences of the mulching vinyl and the fertilizers between the treatments which effect the onion growth during the winter. The content of quercetin in the onions from the recycling filed was increased significantly by 34% and 44% compared to those of the control and normal field, respectively (p < 0.05). It seemed that minerals and biologically active substances in the defective onion extract were effective in increasing the onion growth. In terms of soil microbial biomass, arbuscular mycorrhizal fungi was increased significantly in the recycle field by 40.1% and 30.6% compared to those of the control and normal fields, respectively (p < 0.05). On the other hand, microbial stress (cy19:0/18:1w7c) was decreased in the recycle field by 21.0% and 14.1% compared to those of the control and normal fields, respectively.

This study was conducted to determine the effect of pH adjustment and the addition of cryoprotectants on the storage properties of chicken breast surimi. Surimi as a control was prepared with Alaska pollack by two times of washing treatment and addition of cryoprotectants(4% sugar, 5% sorbitol and 0.3% polyphosphate). Three types of surimi were manufactured by different cryoprotectant conditions(T1: 5% sorbitol+0.3% polyphosphate, T2: 4% sugar+5% sorbitol+0.3% polyphosphate, T3: 2% salt+4% sugar+5% sorbitol+0.3% polyphosphate) and frozen after adjusting the surimi to pH 11.0. The amino acid and saturated fatty acid composition were significantly higher in the control. EAA(essential amino acid), FAA(amino acid in relation to flavor), SAAA(amino acid in relation to saccarinity) and FRAA (fragrant amino acid) were significantly higher in the control. The TBARS(thiobarbituric acid reactive substances) and VBN(volatile basic nitrogen) were increased with storage times. TBARS and VBN values were significantly higher in the control and T3 than the other treatments. The VBN was significantly higher in control and T3 than other surimi samples. Chicken breast surimi adjusted to pH 11.0 had higher in microorganisms than the control, and T1 sample had the highest total plate count. Sensory evaluations were significantly higher in the control and T3 than the other samples. Especially, the overall acceptability of T3 was similar to the control.
