Influence of maturity and storage period on physical and biochemical characteristics of pear during post cold storage at ambient conditions

Abstract

The fruits of semi-soft pear (Pyrus communis) cv. Punjab Beauty harvested at three different harvest dates were stored at 0-1 0 C temperature with 90-95 % Relative Humidity for 30, 45, 60 and 75 days to assess the physical and chemical changes during storage. After every storage interval, the fruits were removed and kept at room temperature for 3 and 6 days to study the shelf life of fruits. Immature fruits always had the highest values of flesh firmness; optimum-mature fruits had the next and over-mature fruits the lowest at each corresponding sampling period during storage. The fruits harvested at optimum stage of maturity exhibited significantly (p<0.05) lower incidence of fruit softening and physiological loss in weight. These fruits retained excellent quality up to 60 days of storage in cool chamber with 3 days shelf life at ambient temperature. The fruits of first harvest date were incapable of developing acceptable flavor and quality upon ripening throughout the storage period. However, the fruits harvested at post-optimum stage recorded maximum physiological loss in weight and lesser firmness thus making them suitable for immediate consumption with no shelf life at ambient temperature storage.

Assessment of physico‐chemical and sensory properties of two date ( Phoenix dactylifera L.) cultivars under commercial cold storage conditions

“…Also, it is relevant to emphasize that fruits harvested with low water content retained excellent appearance, taste, and quality compared to fruits harvested with high MC which showed less acceptability (Kaur & Dhillon, ).…”

Organoleptic evaluation of pears cv. Yanis depending on the time of collection, post-harvest cooling and treatment with an ethylene inhibitor

“…Ступінь стиглості під час збирання є визначальним фактором збереження якості груш [7]. Передчасно зібрані плоди не здатні сформувати аромат, а зібрані запізно вирізняються високими природними втратами і швидко втрачають щільність, зокрема і під час реалізації [8]. Результати зберігання покращують негайним післязбиральним охолодженням [9], однак ефективність подібного заходу залежить від помологічного сорту [10].…”

“…Обробка інгібітором етилену по-різному вплинула на органолептичні показники охолоджених із затримкою плодів обох строків збирання (рис. [7][8].…”

Farklı dönemlerde derimi yapılan hosui asya armut (Pyrus pyrifolia) çeşidinin soğukta muhafaza performansının belirlenmesi

“…derim dönemine ait meyvelerde depolama esnasında her zaman en yüksek ağırlık kaybı değerleri görülmüştür. Bununda meyvelerde olgunluk ilerledikçe yüksek solunum ile transpirasyon kayıplarından kaynaklandığı düşünülmektedir (Kaur and Dhillon, 2015 (Seymour et al, 1993). Ayrıca üründe meydana gelen su kaybı da SÇKM artışında etkili olmaktadır (Öz ve Eriş, 2009 belirlenirken, en düşük toplam fenolik madde miktarı ise 3. ayda III.…”
