The food storing technology is growing fast. Since the optimal storage could increase the value of the material being stored. A proposed solution to overcome counter this issue is the use of modified atmosphere storage (MAS) technology. White oyster mushroom (Pleurotus ostreatus) is one of vegetables that is highly perishable that makes this mushroom has a short shelf life. Therefore, appropriate postharvest handling is needed to maintain the quality of oyster mushrooms by expanding its shelf life. The aims of this research were to assess the effect of the use of MAS technology and to characterize the white oyster mushroom. Based on the research conducted at the Laboratory of Agricultural Processing and Postharvest Engineering, Department of Agricultural Engineering, Brawijaya University showed that the modified atmosphere storage of white oyster mushroom affected the respiration rate and shelf life of the studied commodities. On the basis of the observations on each parameter (respiration rate and storage time), the normal storage time for white oyster mushrooms is 1 day. While iby applying MAS, the white oyster mushrooms could last for 3 days using treatment A (21 % O) and B (12,4 – 12,5 %   O), and could last for 4 days using treatment C (9,2– 9,3 % O2) , D (5,9 – 6,1 % O2), and E (3,5 – 3,7 % O). Therefore, It can be concluded that by using MAS storage at low O2 concentrations, the shelf life of mushrooms could be longer.ABSTRAKTeknologi penyimpanan saat ini berkembang cukup pesat. Hal ini dikarenakan penyimpanan yang optimal akan meningkatkan nilai dari bahan yang disimpan. Salah satu upaya yang dapat dilakukan untuk hal tersebut yaitu penyimpanan menggunakan metode atmosfer termodifikasi (Modified Atmosphere Storage/MAS). Jamur tiram putih (Pleurotus ostreatus) merupakan salah satu komoditas sayuran yang bersifat mudah rusak, hal ini membuat jenis jamur ini memiliki umur simpan yang terbilang singkat. Oleh karena itu, penanganan pasca panen yang tepat pun dibutuhkan agar kualitas jamur tiram dapat dipertahankan sehingga umur simpannya juga lebih lama. Tujuan penelitian ini adalah untuk mengkaji pengaruh penggunaan teknologi penyimpanan dengan MAS terhadap karakteristik jamur tiram putih. Berdasarkan penelitian yang telah dilakukan di Laboratorium Teknik Prosesing Hasil Pertanian, Jurusan Keteknikan Pertanian, Universitas Brawijaya, menunjukkan bahwa penyimpanan dengan atmosfer termodifikasi  dapat mempengaruhi laju respirasi dan lama simpan komoditas jamur tiram putih. Hasil pengamatan pada tiap parameter (laju respirasi dan lama penyimpanan) dapat diketahui bahwa lama simpan jamur tiram putih pada kondisi normal adalah 1 hari. Sedangkan pada kondisi penyimpanan menggunakan metode atmosfer termodifikasi jamur tiram putih dapat bertahan selama 3 hari pada perlakuan A (21 % O2) dan B (12,4 – 12,5 % O), dan bertahan selam 4 hari pada perlakuan C (9,2 – 9,3 % O2), D (5,9 – 6,1 % O2), dan E (3,5 – 3,7 % O2). Sehingga dapat disimpulkan bahwa dengan menggunakan penyimpanan MAS pada konsentrasi O2 yang rendah maka umur simpan jamur akan semakin lama.

Respiration rates (RR) have been used as an index for the metabolic activities of Mango during ripening and senescence. A knowledge on respiration rate will be very much needed for enhanced shelf life of Mango particularly during Modified Atmosphere Storage. Hence a work was carried out to determine respiration rates of three varities of mango (Magnifera indica) viz., Malgoa, Banganapalli and Neelum stored at three different tempertautres (Ambient, 24°C and 14°C). Known weight of fruits were kept under air tight condition in the plastic container fitted with a silicon septum. Every day three gas samples of 5 ml volume were drawn from the chamber through silicon rubber septum using a needle and the oxygen concentration was found out using MAP analyzer. The oxygen concentration was determined for 13 days of storage at all temperatures. The respiration rates were determined using experimentally and the values were substituted in formulae method for prediction. The value of the constants were determined using non-linear regression using Sigmaplot 8.0 software. The development of the mathematical model for the prediction of Respiration Rates were found to be useful for further reference.
