EFFECT OF DRYING KINETICS ON COLOR OF “DEDO DE MOÇA” CHILI PEPPERS (Capsicum baccatum) REA
Andrade,Ednilton T. de; Figueira,Vitor G.; Teixeira,Luciana P.; Martinazzo,Ana Paula; Araujo,Kátia G. de L..
ABSTRACT This study aimed to assess the drying kinetics of red and yellow chili peppers, “dedo-de-moça” variety, at different temperatures (35, 45, 55, and 70 °C) and model this phenomenon mathematically. We also evaluated the effect of these drying air temperatures on pepper fruit color. Pepper fruits were dried in a forced-air circulation dryer. Ten mathematical models were fitted to the experimental data by nonlinear regression analysis. After drying, pepper samples were analyzed for the following colorimetric parameters: lightness (L*), chroma or saturation (c), and hue angle (h), in order to determine the influence of drying air temperature on fruit coloration. Our findings showed that the higher the air temperature, the faster the drying process....

北海道の代表的農産物である小豆,大豆,金時豆を通年温度 7.1 ± 3.4℃である凍土利用貯蔵庫で 6ヶ月間および15ヶ月間貯蔵した時の種皮色に及ぼす影響および貯蔵した小豆から調製したこし餡色への影響について,冷凍貯蔵(-18.9 ± 1.6℃)及び室温貯蔵(24.9 ± 0.1℃)した ものとの相違を明らかにすることを目的とした。紙袋および密封袋で6ヶ月および15ヶ月間貯蔵した小豆種皮の色の明度(L* 値)および彩度(C* 値)は,いずれの貯蔵条件においても貯蔵期間の長さに比例して低下したが,大豆および金時豆のそれらは貯蔵期間の長さに比例して上昇し た。15ヶ月間室温貯蔵した小豆の種皮色の色差は1.95(紙袋)および2.02(密封袋),凍土利用貯蔵したそれらは 1.48(紙袋)および0.95(密封袋),冷凍貯蔵したそれらは0.96(紙袋)および 0.93(密封袋)であった。6ヶ月および15ヶ月間凍土利用貯蔵した小豆から調製したこし餡 の色の明度(L* 値)および彩度(C* 値)は,貯蔵小豆の種皮色のそれらの値と同じ傾向を示し,貯蔵期間の長さに比例して低下した。15ヶ月間室温貯蔵した小豆から調製したこし餡の色差は7.54(紙袋)および7.05(密封袋)であり,凍土利用貯蔵した小豆から調製したそれらは7.27(紙袋)および 4.33(密封袋),冷凍貯蔵した小豆から調製したそれらは7.65(紙袋)および3.46(密封袋)であった。これらのことから,豆類の貯蔵は密封袋がよく,密封袋で凍土利用貯蔵を行うことで,種皮色の色差に及ぼす影響は殆どわずかで,またこし餡の色差に及ぼす影響も低いことが示された。

Development and quality of pineapple guava fruit in two locations with different altitudes in Cundinamarca, Colombia Bragantia
Parra-Coronado,Alfonso; Fischer,Gerhard; Camacho-Tamayo,Jesús Hernán.
Fruit growth is stimulated by different weather conditions. The aim of this study was to determine the influence of weather conditions on the physicochemical properties of pineapple guava fruit growth. Twenty trees were marked in two production areas located at different altitudes (1,800 and 2,580 m.a.s.l.), and measurements were performed every 7 days from 99 and 141 days post-anthesis to harvest at altitudes of 1,800 and 2,580 m.a.s.l., respectively. The results indicate that altitude and weather conditions greatly influence the growth and development of pineapple guava fruit, and these effects are primarily manifested in the physical characteristics of the fruit. The weight and size of the fruit at harvest are directly related to the altitude of the...
