  • Quality evaluations of seasoning chicken wing treated with pine needles during storage of 6 days at $4^{\circ}C$ were assessed. Seasoning chicken containing 0.5-1.3% (w/w) pine needle during storage at $4^{\circ}C$ was allowed to the growth of Staphylococcus aureus. pH values of seasoning chicken containing pine needles after 6 days of storage were not significantly different (p>0.05) than those of the controls. The rate of drip loss on seasoning chicken containing pine needles after 24 hr of storage was significantly different (p<0.05) than that of the controls. Sensory scores of seasoning chicken containing 0.8-1.3% pine needles for odor and flavor were in the "liked more" to typical category during storage of 6 days at $4^{\circ}C$. For odor and flavor scores, seasoning chicken containing 1.0-1.3% pine needles compared to the controls and other treatments increased during storage days due to fresh odor of pine needles. Seasoning chicken containing 0.5-1.3% pine needles after 6 days of storage were no significantly different levels (p>0.05) of Hunter color $L^*$ values compared to controls. Hunter color $a^*$ and $b^*$ values of seasoning chicken containing 0.5-1.3% pine needles after 6 days of storage were significantly different (p<0.05) than those of the controls.

  • The effect of 1-methylcyclopropene (1-MCP) in the storability of kimchi cabbage at cold storage condition was investigated. Kimchi cabbage (Brassica campestris L. cv Ryouckgwang) was divided four groups, forced air cooling (FAC), FAC + 0.03 mm linear low density polyethylene liner (Liner), $FAC+2{\mu}L{\cdot}L^{-1}$ 1-MCP (1-MCP), and FAC + 1-MCP + Liner. After each treatment kimchi cabbage was stored at $2^{\circ}C$, 95% RH. Quality parameters were weight loss, soluble solids content (SSC), firmness, and color ($CIE\;L^*$, $a^*$, $b^*$, chroma, hue angle). Weight loss during storage was showed significant difference by Liner treatment. In particular FAC + 1-MCP + Liner treatment showed 12.5% reduction after 6 weeks of storage period and minimized the weight loss rate compared to other treatments. SSC of kimchi cabbage was $2.5^{\circ}Brix$ at harvest and FAC + 1-MCP + Liner treatment maintained the SSC until 3 weeks, while in other treatments gradually were increased. The firmness of kimchi cabbage was 24.0 N immediately after harvest and the firmness at harvest time tended to be maintained at 22.6 N after 6 weeks of storage in FAC + 1-MCP + Liner treatment. During the storage period, the color change of the kimchi cabbage leaf can be confirmed by $CIE\;a^*$ and hue angle value. 1-MCP treatment alone did not affect the color change, however 1-MCP + Liner treatment was able to maintain the chromaticity at harvest time while minimizing the change of $CIE\;a^*$ and hue angle. These results suggest that 1-MCP treatment is not effective for the storage of kimchi cabbage but can be maintained for up to 6 weeks when treated with Liner.

  • The purpose of this study is to assist farmers in determining the optimal time for the shipment of stored apples by investigating the market trends, storage status and release dates of low-temperature stored apples. We surveyed 300 apple cultivation farms in Daegu, Gyeongbuk Province, which is the main producer of apples, and examined the cultivars, cultivation areas, storage conditions, and shipment status of apples. The main results are as follows: the proportion of apples cultivatedat different ripening times was surveyed. According to the results, the proportions of early, middle and late varieties were 78.3%, 63.7% and 96.0%, respectively. Also, 48.7% of the farm households surveyed had cold storage facilities. The average storage cost per apple box(15kg) was 978.3 won for self-storage and 1,771.8 won for consignment storage. For the six(6) months between November and April, the proportion of shipped apples was 91.6% of the total stored apples. The (average total?)annual apple shipment, including apples stored in general storage warehouses, was 744.4 boxes. The (average total?) annual shipment of cold storage apples was 616 boxes. The stored apples were mainly shipped to 'wholesale markets', which have the highest sales share, followed by 'production site collectors' and then 'supermarkets'. The most common shipping method of the apples was by general trucks, followed by low-temperature trucks, and finally by delivery services. The analysis of the factors influencing the decision to release apples by period showed that it was affected by the storage cost, loss rate, and customary shipping in the off-season(from May to August). On the other hand, in the general release season(from November to April), the statistically significant decision factors for the release of apples were the future expected price, storage cost and decision of the leading farmer groups. For farmers with a high share of general shipment, the deciding factors for the release of apples were the future expected price, storage cost, high income expectation, and decision by leading farmers.

  • Quality of fresh ginger deteriorates rapidly during low temperature storage, and its storage life is short due to sprouting and microbial spoilage. The objectives of this research were to develop, using additives, a minced ginger product, which could maintain acceptable quality for over 30 days, and to investigate its quality changes during the cold storage. Storage stability of minced ginger product was investigated from the standpoint of the inhibition of brown discoloration, gas formation and liquid-solid separation. Fresh ginger was peeled and ground to produce minced ginger (control). Sodium bisulfite, L-cysteine, NaCl, sodium benzoate, modified starch, and/or xanthan gum were added to the control to minimize quality loss during storage, and to develop an optimum formula (A) of minced ginger. Samples were packed in Nylon/PE films, stored at $5^{\circ}C$, sampled at a 30-day interval, and subjected to quality evaluations. Changes in pH, surface color, gas formation, liquid-solid separation, contents of free amino acids, free sugars, organic acids, and fatty acids were determined. Gas formation was effectively inhibited in samples with sodium benzoate and/or NaCl. Samples with xanthan gum did not result in liquid-solid separation. L-Cysteine and sodium bisulfite were effective in controlling discoloration. pH decreased during storage in all samples, except sample A. Organic acid contents of all samples increased during storage, with lactic acid content showing the highest increase. Free amino acid content decreased with increasing storage time. Free sugar content of all samples decreased during storage. Sensory results showed sample A maintained acceptable quality until 90 days of storage. These results suggest that quality of minced ginger could be successfully maintained with the additions of selected additives for up to 90 days.

  • This study was performed to evaluate the quality change of pork patties containing silkworm powder and vegetable worm (Paecilomycis japonica) stored for 9 days at $5^{\circ}C$. pH values were higher in treatment groups than that in controls by storage day 6. L (lightness) and a (redness) value were decreased with increasing addition of silkworm powder and vegetable worm powder in pork patties (p<0.05). However, b value (yellowness) was increased with increasing addition amounts of the silkworm powder and the vegetable worm powder (p<0.05). Water holding capacity (WHC) of pork patties was not affected by the silkworm powder and the vegetable worm powder, while pork patties containing 0.4% silkworm powder (T2) showed low cooking loss (p<0.05). Pork patties containing either silkworm powder and vegetable worm alone or a combination of them showed lower lipid oxidation value than that of control (p<0.05). Sensory preference of pork patties was decreased with increased of storage days. The overall acceptance was higher in treatment groups than at control groups at the initial day (p<0.05), yet no significant difference was found during storage. From these results, 0.4% silkworm powder decreased not only cooking loss but also lipid oxidation of pork patties. Also, no adverse effect was found in water holding capacity (WHC) and sensory preference of pork patties. Therefore, the silkworm powder and the vegetable worm powder could be useful to pork meat product industry as additives.

  • This study was conducted to investigate the effect of CA(4% $O_2$ and 7.5% $CO_2$) storage on the quality characteristics and chilling injury in 'Nanko' prunus mume fruits at 1, 5, and $9^{\circ}C$. CA storage reduced production of $CO_2$ and $C_2H_4$ significantly. Hue values of fruit skin were significantly higher in fruits stored at $1^{\circ}C$ and $5^{\circ}C$ than $9^{\circ}C$. Weight loss was much lower in fruits stored under CA storage. Soluble solids content (SSC) titratable acids (TA), and firmness were maintained and electrolyte leakage was lower in fruits stored under CA storage. Ratios of chilling injury and decay were increased faster at $5^{\circ}C$ and $9^{\circ}C$ than $1^{\circ}C$. The chilling injury was suppressed in fruits of CA storage compared with control fruits during cold storage. These results indicate that CA storage at $1^{\circ}C$ of prunus mume fruits extended the storage life up to 30 days without quality deterioration. effectively.

  • The effect of chitosan and cacium treatment on the quality of satsuma mandarin(Citrus unshiu Marc. var. miyagawa) during storage were investigated. Citrus fruits treated with 2000-folds diluted iminoctadime-triacetate solution or 1.5% chitosan with 0.5% CaCl$_2$ solution were stored at 4$\^{C}$ and 87$\pm$3% relative humidity, and room temperature without humidity control. Decay ratio of chitosan and calcium treated fruits were lower than the ones with no treatment from the mid of February. Also, citrus fruits treated with chitosan and calcium treated less in weight loss, that seems it was derived from restraining of fruits' transpiration. Soluble solids were maintained higher level in chitosan and calcium treated fruits than with no treatment during the storage. Acid contents were decreased gradually lower in cold storage than in room temperature storage, and there was not showed consistent trend among treatments. 26 kinds of free amino acids among 45 standards such as glutamic acid, threonine, serine, alanine γ-amino buryric acid, aspragine and etc were detected in Citrus unshiu Marc. var. miyagawa. As the storage time was prolonged, free amino acid was disappeared more or less, and the deccreasing extent was less in 4$\^{C}$ than in room temperature storage.

  • In this study, the physicochemical, microbial, and sensory properties of law-fat hamburger patties during storage for 25 days at $7{\pm}1^{\circ}C$ were investigated. The law-fat hamburger patties were manufactured by three different packing methods (control: added with 10% lard regular-fat patty, T1: added with 10% lard and organic vegetable of regular-fat patty, T2: added with 3% olive oil of vegetability low-fat patty, T3: added with 3% lard of low-fat patty). The pH of all treated samples increased as the storage time increased, and then decreased after 15 days of storage. The low-fat hamburger patty added with organic olive oil (T2) showed significantly higher pH (p<0.05) compared with other treatments (T1 and T3). The TBARS values of the all treated samples tended to increase after 5 days of storage, and then significant quality loss was observed after 15 days of storage period for the control (T1). However, the samples of the vegitability low-fat patty added organic olive oil had longer shelf-life than the control. The total bacterial counts were 7 log CFU/g after 15 days and 20 days of storage for the control and treatments, respectively. The results of this study showed that the storage period of the treatments was slightly extended compared with the control. Low-fat hamburger patties showed no differences for overall acceptability between control and other patties.

  • Studies were carried to evaluated the influence of storage method by temperatures and fillers on yield and quality of seed rhizome in turmeric. Seed rhizome was stored at styrofoam box filled with rice hull and sand (3:1) or vermiculite for 30, 60 and 90 days at different temperatures (5, 10 and $15^{\circ}C$. compared to traditional method (rhizome only). Parameters were obtained for weight loss, cold injury, percentage of decayed in stored rhizome during storage periods. Also, the germination, growth pattern and yield from stored rhizome has been investigated. It was confirmed that storage of turmeric in stored with filled with vermiculite helps in prevention of rhizomes from microbial and fungal attack. The storage of rhizomes in styrofoam box without any filler at low temperature below $10^{\circ}C$. is not advocated due to heavy losses weight and decayed in management of postharvest for turmeric rhizome. Germination percentage, growth pattern and yield was maximum for rhizomes stored at styrofoam box filled with vermiculite for 90 days at $15^{\circ}C$. The paper outlines a brief attempt to assess the efficacy of non-chemical methods including optimal storage method (temperature and filler) of control of decay and moisture losses during storage of turmeric.

  • This study was conducted to evaluate the effects of injection of red wine on physico-chemical characteristics of pork loin ham during cold storage. The pork loin hams were manufactured by injection of red wine as Control (0%), T1 (3%), T2 (6%), T3 (9%), and were analyzed, while stored at 10±1℃ for 4 weeks, respectively. As a result of the injection of red wine, the pH values of pork loin ham were reduced, whereas WHC values were increased compared to the control (p<0.05). However, there was no significant difference in cooking loss. In meat color, as injection of red wine increased, the lightness values were reduced, and redness values were increased during 4 weeks. In texture profile analysis, values in shear force, brittleness, gumminess and adhesiveness were increased as red wine injection increased (p<0.05). But, injection of red wine reduced the VBN values until 2 weeks. Treatment groups with more than 3% red wine showed lower TMC values than control until 3 weeks (p<0.05), whereas Lactobacillus counts were significantly increased by injection of red wine since 2 weeks. In conclusion, red wines showed the effect of increasing the quality characteristics related to physical and storage in pork loin ham during cold storage, and proper injection level was 3% when pork loin ham processed.
