Çalışmada halojen ısıtıcılı kurutmada kurutma sıcaklıklarının kültür mantarının (Agaricus bisporus) kurutulmasında kuruma süresi ve rehidrasyon oranına etkileri araştırılmıştır. 1 cm kalınlıkta kesit alınan örnekler halojen ısıtıcılı kurutucuda 40, 50 ve 60°C’de kurutulmuştur. Kuruma eğrileri ilk saatte 10’ar dk devamında 30 dk periyotlarda örnek ağırlıkları kaydedilerek oluşturulmuştur. Rehidrasyon oranı kurutulmuş örneklerin 10, 20, 30, 60 ve 1440 dakikalık rehidrasyon sonucu %ağırlık artışıyla ifade edilmiştir. Mantar örneklerinin 40, 50 ve 60°C’de kurutulmalarında son nem içeriğine (%6.58) ulaşma süreleri sırasıyla 480, 240 ve 150 dk iken rehidrasyon oranları %92.02, 90.53 ve 90.40 olarak kaydedilmiştir. Çalışmada kurutma sıcaklığının artmasının kuruma süresini kısalttığı ancak rehidrasyon oranında azalmaya sebep olduğu görülmüştür. İki yönlü varyans analizlerinde ise sıcaklık artışının kuruma süresi üzerine etkisi istatistiksel olarak önemli (p<0.05) iken rehidrasyon oranına etkisi önemsiz bulunmuştur (p>0.05).
The study has studied the effects of drying temperatures in hallogenic heater drying on the drying time and guidance rate in the drying of culture fungi (Agaricus bisporus). Examples cut in 1 cm thickness are dried at 40, 50 and 60°C in the halogen heater. The body curves are created by recording sample weights in the periods of 30 minutes in the first hour of 10 minutes. The hydration rate was expressed by a percentage weight increase as a result of the hydration of 10, 20, 30, 60 and 1440 minutes of dry samples. The time of arrival to the final moisture content (6.58) when the mushrooms are dry at 40, 50 and 60 °C is 480, 240 and 150 minutes respectively, while the guidance rates are recorded at 92.02, 90.53 and 90.40. The study found that the increase in drying temperature shortened the drying time but caused a decrease in the guidance rate. In the two-way variance analysis, the impact of the temperature increase on the drying time was statistically significant (p<0.05) while the impact on the guidance rate was not significant (p>0.05).
Present work investigated the effect of drying temperature on drying time and rehydration rate of white button mushroom (Agaricus bisporus) in halogen heated drier. Samples having 1 cm thickness were dried at 40, 50 and 60oC in halogen heated drier. Drying curves were prepared from the plots of sample weight losses during drying at the time interval of 10 min for first hour of drying and 30 min for the rest. Rehydration rates were determined by the weight gain of dried samples in 10, 20, 30 60 and 1440 mins of rehydration. Drying time of mushroom samples to reach final moisture content of 6.58% were 480, 240 and 150 min for drying at 40, 50 and 60oC while rehydration rates were 92.02, 90.53 and 90.40% respectively. Study showed that the increase in drying temperature resulted in decrease drying time and rehydration rate. Two way variance analyses indicated that the effect of drying temperature increase on drying time was statistically important (p<0.05) this effect on rehydration rate was not statistically important (p>0.05).
