Development of Freezing Time Prediction Model and Thermo-physical Properties of Frozen Kimchi
Korean Journal of Food Preservation, volume 10, issue 2, 2003, Pages 125~130
This study was carried out to investigate the thermo-physical properties and design Freezing time prediction model from data of freezing test of Kimchi. Density of Kimchi were measured as 1001.9
0.03 kg/㎥ at unfrozen state, 987.0
0.07 kg/㎥ at frozen state and volume of the Kimchi expanded 4.67% at -l5
. Initial freezing point of Kimchi and seasoning were -4.0
, respectively. Freezing ratio of Kimchi were estimated more than 50％ at -5.0
, more than 75% at -l0
and approximately 90% at -25
. To obtain equation for freezing time prediction of Kimchi, freezing time(Y) was regressed against the reciprocal(
) of difference of initial freezing point and freezing medium temperature, reciprocal(
) of surface heat transfer coefficient, the initial temperature(
) and thickness(
) of samples. As results of the multiple regression analysis, equations were obtained as follows. Y
=0.9632). These equations shown better results than previous models, and the accuracy of its was very high as average absolute difference of about 10% in the difference between the fitted and experimental results.

Korean Journal of Food Preservation, volume 10, issue 2, 2003, Pages 131~135
Bell pepper was packed with several plastic films, and investigated the quality Characteristics such as gas composition, weight loss, microbial load, soluble solid content, ascorbic acid and color during storage at 10
. Cast polypropylene (CPP), low density Polyethylene (LDPE), Polyolefin (MPD, PD961) and linear low density polyethylene (LLDPE) were used for this purpose. Oxygen concentration inside packages generally showed a 10∼14% after 1∼2 weeks, but package with CPP maintained above 15％ throughout the storage. Carbon dioxide concentration of CPP was above 2%, but other treatments showed below 2%. Weight loss of all treatments was below 3.0% after 5 weeks. Total microbial count showed a similar pattern compared to yeast and mold, and CPP maintained the highest microbial load after 3 weeks. Yellowness (b value) of bell pepper was generally increased throughout the storage, and MPD and PD961 were higher than other treatments.
Effects of Surface Treatment with Polyethylene Film on Shelf-life of Packaged Kimchi
Korean Journal of Food Preservation, volume 10, issue 2, 2003, Pages 136~141
This they was conducted to investigate the surface treated effect of Packaged kimchi on the PH, acidity, total microbe, number of lactic acid bacteria, browning and formation of off-flavor during storage at 10
. Kimchi was treated with 70% ethanol(1 time spraying) and attachment of polyethylene film(PE) on the surface of packaged kimchi and stored at 10
. pH of the control and ethanol treated kimchi stored for 15 days was decreased to 4.0 level but, the pH of PE-treated kimchi maintained over pH 4.0 until 21 days of storage. The aridity was the same tendency as the pH, which showed delaying of fermentation by PE treatment. Total microbe of PE treated kimchi was lower and number of lactic acid bacteria was higher than those of control and ethanol treated products, respectively. Degree of browning and off-flavor of control and ethanol treated kimchi increased from 13 days of storage, but the degrees of the PE-treated kimchi was lower during all storage periods.
Effect of Respiration and Transpiration Rates on the Weight Loss of Various Fruits(Peach, Apple, Pear, Persimon, Mandarin)
Korean Journal of Food Preservation, volume 10, issue 2, 2003, Pages 142~146
In order to prepare allowable guidelines for weight loss for packed agricultural produces during distribution after harvest, resipration and transpiration rates were investigated for fruits such as peach, apple, pear, persimon and mandarin which produced in Korea. Respiration and transpiration rates were widely different from cultivar and harvesting season among same produces. Respiration rates were increased as an environmental temperature was increased. Moisture amount that produced by respiration in five fruits was 3.55∼107.67mg/kg/h and those moisture amounts were considered as no much influence for the strength of cartons for packing of fruits. Moisture amount produced from transpiration was 24 ∼ 1,195g for 15kg packing unit of fruits in 5 days. after harvest.

To examine the quality changes of three typical fishes under usual storage conditions during marketing, we determined the total bacterial counts and pH values during storage of mackerel, croaker, and saury. Mackerels were stored at 0
and on ice at 19
, which is the usual storage condition in a local market and croakers and saury were stored at 0
. Total bacterial counts of mackerel, croaker, and saury were 3,2
, and 2.8 x 10
CFU/g at the time of storage respectively. Total bacterial counts of mackerel stored on ice at 19
increased during storage and reached to 8.4 x 10
6/ CFU/g at day 6, while those stored at 0
decreased up to 2 days of storage and increased to 5.6
CFU/g. For croaker and saury, total bacterial counts at 0
5/ and 2.1 x 10
5/ CFU/g at day 6, respectively, while those stored at 4
had 3.6 x 10
6/ and 2.6
5/ CFU/g. the pH value or mackerel was 5.56 at the time or storage, yet it increased to 6.04. The pH changes of croaker and saury had a similar pattern with that of mackerel, which increased with time of storage. These results suggest that storage of fishes at 0
should be better than those at 4
or on ice at 19
in terms of microbial safety as well as quality and shelf-life of fishes.
