SIFAT KIMIA DAN KINETIKA DEGRADASI TERMAL ANTIOKSIDAN JUS MELON (Cucumis melo L.) KULTIVAR GAMA MELON PARFUM

نویسندگان

چکیده

Sebagai salah satu kultivar melon lokal unggul, Gama Melon Parfum (GMP) sangat potensial karena mengandung antioksidan alami. GMP dapat dikonsumsi dalam bentuk jus dan dinikmati oleh masyarakat luas. Tujuan penelitian ini adalah mempelajari sifat-sifat serta mengevaluasi nilai D Z sifat antioksidannya yang meliputi kandungan total fenolik, vitamin C, aktivitas antioksidan. Penelitian menggunakan dua faktor yaitu variasi suhu (65, 77, 88, 92 o C) waktu (0, 10, 20, 30 menit) pasteurisasi dengan pengulangan sampel sebanyak tiga kali. Hasil menunjukkan bahwa proses mempengaruhi mendegradasi antioksidan, asam berturut-turut sebesar 51%; 16,8%; 84%; 296%. Akan tetapi pH meningkat setelah dipasteurisasi persentase 1,6%. Kinetika degradasi didekati kinetika reaksi orde pertama pertama. Rentang C 97,09-714,29 menit, 400-1666,67 38,76-222,22 menit. Nilai 32,15; 46,95; 37,04 °C. Ketiga parameter dievaluasi memiliki sensitif terhadap perlakuan termal. Kata kunci — Aktivitas termal, Jus melon, Parfum, Pasteurisasi

The genome of melon (Cucumis melo L.).

We report the genome sequence of melon, an important horticultural crop worldwide. We assembled 375 Mb of the double-haploid line DHL92, representing 83.3% of the estimated melon genome. We predicted 27,427 protein-coding genes, which we analyzed by reconstructing 22,218 phylogenetic trees, allowing mapping of the orthology and paralogy relationships of sequenced plant genomes. We observed the ...

Mapping and Characterization of the fefe Gene That Controls Iron Uptake in Melon (Cucumis melo L.)

Iron (Fe) deficiency in plants limits crop growth and productivity. Molecular mechanisms that plants use to sense and respond to Fe deficiency by coordinated expression of Fe-uptake genes are not fully understood. The C940-fe chlorotic melon (Cucumis melo) mutant known as fefe is unable to upregulate Fe-uptake genes, however, the FeFe gene had not been identified. In this study, we used two F2 ...

Response of squash (Cucurbita spp.) as rootstock for melon (Cucumis melo L.)

The effects of different Cucurbita spp. rootstocks on melon cultivars belonging to different horticultural groups were studied by comparing grafted plants with non-grafted ones under greenhouse and open ®eld growing conditions. Winter melons (Cucumis melo L.) of the Inodorus group, cvs. `Thraki', `Peplo' and `Lefko Amynteou', and a summer melon of the Cantalupensis group, cv. `Kokkini Banana', ...

The Alcohol Dehydrogenase Gene Family in Melon (Cucumis melo L.): Bioinformatic Analysis and Expression Patterns

Alcohol dehydrogenases (ADH), encoded by multigene family in plants, play a critical role in plant growth, development, adaptation, fruit ripening and aroma production. Thirteen ADH genes were identified in melon genome, including 12 ADHs and one formaldehyde dehydrogenease (FDH), designated CmADH1-12 and CmFDH1, in which CmADH1 and CmADH2 have been isolated in Cantaloupe. ADH genes shared a lo...

The Cinnamyl Alcohol Dehydrogenase Gene Family in Melon (Cucumis melo L.): Bioinformatic Analysis and Expression Patterns

Cinnamyl alcohol dehydrogenase (CAD) is a key enzyme in lignin biosynthesis. However, little was known about CADs in melon. Five CAD-like genes were identified in the genome of melons, namely CmCAD1 to CmCAD5. The signal peptides analysis and CAD proteins prediction showed no typical signal peptides were found in all CmCADs and CmCAD proteins may locate in the cytoplasm. Multiple alignments imp...
