When the fruit reached the edible-ripeness stage 12 days after harvest, the values of those characteristics were 9.3 (peel color index), 12.7 Brix % (soluble solid concentration), 1.4 N (flesh firmness), 1.8 × 106 (elasticity coefficient) and 1.1 × 107 (viscosity coefficient). In addition, the elasticity indices that were calculated from the frequency of second resonance and the third resonance were 9.5 × 106 and 17.4 × 106, respectively. Film packaging of the pear fruit resulted in inhibition of moisture loss, yellowing of the peel, softening of the flesh and saccharification of starch during ripening. The characteristics of the film-packaged fruit 12 days after harvest were 3.7 (peel color index), 20% (potassium iodide reaction), 12.5 N (flesh firmness), 15.0 × 106 (elasticity coefficient), 15.0 × 107 (viscosity coefficient), 29.5 × 106 (Emf2) and 66.2 × 106 (Emf3). These findings clarify the ripening characteristics of ‘Koshisayaka’ pear fruit and the delaying effect of film packaging on fruit ripening. The delaying effect on fruit ripening is suggested to be due to decreased level of oxygen in film. Furthermore, the possibility of a nondestructive method for estimating the ripening stage is suggested by the correlation between the elasticity index and fruit softening.","subitem_description_type":"Abstract"},{"subitem_description":"越さやか’の果色値および可溶性固形物濃度は追熟中に上昇し，果肉硬度，弾性率，粘性率および弾性指標は低下した．果実が収穫後12日に適食状態に達した時の果実特性の値は，9.3（果色値），12.7 Brix％（可溶性固形物濃度），1.4 N（果肉硬度），1.8 × 106（弾性率）および1.1 × 107（粘性率）であった．さらに，f2およびf3から算出した弾性指標は9.5 × 106（Emf2）および17.4 × 106（Emf3）であった．一方，収穫後の果実へのフィルム包装は水分消失，果皮の黄化，果肉の軟化，ならびにデンプンの糖化を抑制した．収穫後12日におけるフィルム包装した果実の果実特性は，3.7（果色値），20％（ヨードカリデンプン反応），12.5 N（果肉硬度），15.0 × 106（弾性率），15.0 × 107（粘性率），29.5 × 106（Emf2）および66.2 × 106（Emf3）であった．以上の結果から，‘越さやか’果実の追熟特性ならびにフィルム包装による果実の追熟抑制効果が明らかになった．この追熟抑制効果はフィルム内の酸素濃度の低下によることが示唆された．また，‘越さやか’の弾性指標が果肉の軟化とともに低下したことから，非破壊計測技術による熟度推定の可能性が示唆された．","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39214","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Chino,
