  • Three seasme cultivars were compared in viewpoints of ripening developments and yielding potentials per plant after the flowering date. On this study, timely ripening and yielding developments were checked separately with capsules and seeds which outcome from the flowers labelled at 30th of July, the maximum flowering stage. Mostly, size and dry weight developments were estimated and the results obtained are as follows; 1. "Early Russian" was recognized as an ideal cultivar with large sized capsule and high lipid contents. However, under the enough ripening periods and ripening conditions (temperature, lights, and nutrients, etc.), the cultivar has weakness on the capsule developments which is competed with seed developments as mean of sink concern. 2. "Suwon 5" was a high yielding cultivar under the proper ripening weather (F. ex. southern districts), but under the unfavorable ripening conditions the cultivar may have weakness of rapid yield decrease by comparatively later formation of seed weight than the capsule. Especially the cultivar has the very ripening characteristics adapting to southern districts which have higher temperature and later low limiting stage for sesame ripening. 3. "Black colored native" seasme cultivar showed lower yielding and later ripening characteristics among others. Also, under the unfavorable ripening conditions, the cultivar has the weakness of yield decrease. Even under the favorable conditions, the cultivar will still have the weakness which is not able to increase in yield, because the capsule development would be finished in size and dry weight too early to accept the later developments of seeds.e later developments of seeds.

  • This study was conducted to understand the characteristics of fruit softening during ripening which causes deep loses in quality of horticultural products during storage and marketing process after harvest. The changes of cell wall components during ripening was investigated. The climacteric rise was between 42 and 49 days after anthesis and then decreased. Ethylene evolution was similar to respiration. The hardness of fruit decreased markedly at this climacteric period and significances of textural parameters among the ripening periods were recognized but the significance between 50 and 55 days after anthesis was not. Sugar components of cell wall polysaccharides were uronic acid, galactose, glucose, arabinose, xylose, rhamnose, mannose and fucose. The contents of arabinose and mannose in alcohol-insoluble solids fraction increased, but other sugars were not changed. In cell wall fraction, the contents of uronic acid, galactose, glucose and arabinose were comparatively high, but galactose, arabinose and ironic acid were decreased markedly during ripening. ironic acid occupied above 75% of total monosaccharide in pectin fraction and decreased markedly during ripening. In acid-soluble hemicellulose fraction, the contents of uronic acid, glucose, galactose and rhamnose were high and they decreased from 50 days after anthesis. The contents of glucose and xylose were high in a alkali-soluble hemicellulose fraction and they decreased markedly at 55days after anthesis.

  • The effect of addition commercial fish collagen hydrolysate and encapsulated fish collagen hydrolysate on the quality characteristics of sucuk (a traditional Turkish dry-fermented sausage) was investigated. Fish collagen hydrolysates were encapsulated with maltodextrin (MD) which has two different dextrose equivalent (12DE and 19 DE), with two different types of core/coating material ratios (10% peptide : 90% MD, 20% peptide : 80% MD). Than six group of sucuk dough (control, peptide, MD1210, MD1220, MD1910, MD1920) prepared and naturally fermented. The effects of the ripening period (28 d), treatment (peptide and encapsulated peptide addition) 'ripening period ${\times}$ treatment' interaction on sucuk's pH, lactic acid contents, $a_w$ values and moisture contents were statistically significant (p<0.01). The pH, moisture and $a_w$ decrease and lactic acid concentration increses during ripening period. The highest pH was observed with peptide added group (5.41), and encapsulated peptide added groups (4.76-4.77) were lower than the control group (5.26). Lactic acid concentration was affected from treatment and all treatment groups lactic acid concentration (0.185-0.190%) were higher than the control group (0.164%). Antioxidant and Angiotensin converting enzyme inhibition activities of water soluble protein extracts were significantly (p<0.01) increased during ripening time. Antioxidant activity reached the highest level at $28^{th}$ d. There was no significant increase observed after fermentation for both activities. Antioxidant activity of encapsulated peptide added (%39.56-40.48) groups were higher than control (34.28%) and peptide added (33.99%) groups except MD1920 (38.30%). The effect of the ripening period of the sucuk samples on TBA values was found to be statistically significant (p<0.01) while treatment and 'ripening period ${\times}$ treatment' interaction were not to be significant (p<0.05). The value of hardness was the highest in the encapsulated peptide added groups (29.27, 35.83 N), and it was 20.40 N and 15.41 N in the peptide added group and the control group respectively.

  • In this study, Red pearl (4x) and MBA (2x) were crossed Gangwon-do Agricultural Research and Extension Services in 2000 to compare the brewing characteristics of Cheonghyang, a seedless kind of grape registered in 2009, by maturity. Fruit characteristics of Cheonghyang were examined after the first racking and 300 days after fermentation during aging in manufacturing wine based on maturity categories of being immature, mature, and overmature after harvest between August 25 and 27, 2014. The soluble solid matter content did not differ between the first racking following manufacturing wine and during ripening, and the alcohol content following the first racking was 12.9% for immature ones, 13.0% for mature ones, and 12.7% for overmature ones., The alcohol content decreased by appropriately 1.3% to 1.8% during ripening. The total acidity content was 0.9% for immature ones, 0.8% for mature ones, and 0.5% for overmature ones following the first racking and showed insignificant variations during ripening of 0.8%, 0.7%, and 0.5%, respectively, with wine made from mature ones showing proper acidity. The volatile acid content following the first racking during ripening, showing insignificant variation by maturity; however, it decreased after ripening. The sensory evaluation detected differences in acidity of wine between mature and overmature grapes. There was no difference in sour taste between immature and mature grapes; however, overmature ones had low levels of sour taste. Our results showed that mature wine had the best overall preference.

  • To develop a healthy functional food containing Rubus coreanus fruit (RCF) powder with different degrees of ripening, the composition, physicochemical properties, and antioxidant activity of native RCF during ripening were investigated and compared with Rubus occidentalis fruit (ROF). Ripened RCF was bright red in color, whereas ripened ROF was dull and dark red in color. The seeds of RCF were softer and smaller than those of ROF. Crude protein, crude lipid, and total sugar content of RCF powder increased with increased ripening time, whereas ash and total dietary fiber contents decreased with increased ripening time. Color differences increased with Increased ripening. Eighteen types of amino acids were analyzed from RCF, and glutamic acid had the highest content. RCF powder had the highest level of potassium and calcium and did not contain any hazardous metals. Mineral and organic acid contents decreased according to ripening.

  • The effects of adding shrimp (Periclimenes imperator) powder to Appenzeller cheese on quality and characteristics during ripening were investigated. Cheese samples were prepared containing 1.0%, 2.0%, and 3.0% shrimp powder. Changes in the lactic acid bacterial populations, pH, water-soluble nitrogen concentrations, consumer acceptability, colour and texture were monitored during ripening. The addition of shrimp powder did not affect the appearance or consumer sensory characteristics of the cheeses. Likewise, cheese cohesiveness, fracturability, and springiness were not significantly altered. It was concluded that the quality of the Appenzeller cheese was not affected by adding shrimp powder.

  • In this study, Staphylococcus carnosus isolated from traditional sucuk (Turkish dry-fermented sausage) was used in combination with Lactobacillus plantarum as a lactic culture in sucuk production. Sucuk produced with only L. plantarum was evaluated as a control group. Microbiological, physicochemical, and volatile profile characteristics of sucuk samples were investigated during ripening. In both sausages with S. carnosus and control group, pH value decreased to below 5.0 at the $3^{rd}$ day. In all samples, Aw value decreased as the ripening time progressed. Sausages with S. carnosus showed the higher nonprotein nitrogen (NPN) value than control group. However, the highest mean value for thiobarbituric acid reactive substances (TBARS) was observed in control group. Enterobacteriaceae dropped to undetectable levels at the $3^{rd}$ day in both groups. S. carnosus increased approximately 1 log unit within the first 3 days of the fermentation. In the presence of S. carnosus, significant changes were observed in only a few volatile compounds.

  • In order to obtain the basic data fer the processing adaptability of Korean figs(Ficus carica L.), physicochemical analyses were carried out with Korean common type figs in the different ripening stages. Moisture contents decreased, but the contents of protein, fat carbohydrate and soluble solids increased according to the ripening of fruits. K was detected as the most abundant one of all the minerals and Ca, Mg, Na, Fe, Mn, Zn and Cu were the next in order. The mineral contents decreased slightly with ripening. Especially, Ca, Mg, U, Fe and Zn were higher in the unripened H stage figs. The antioxidative activity was assayed with water and methanol extracts from ripened figs by the DPPH radical scavenging ability. The antioxidative activities of Korean figs were relatively high and increased in a dose dependent manner. The methanol extract showed the higher antioxidative activity than the water one. Therefore, the methanol was the better solvent than water for the antioxidative compounds. These results suggested that Korean figs are relatively the good sources of minerals, especially the Ca and the antioxidative compounds.
