Abstract

The aim of research provides information physicochemical characters of three levels of maturity picking of mangosteen fruit in storage at both low and ambient storage temperature. Mangosteen fruit was obtained from production centers in villages Puspahiang, Puspahiang, Tasikmalaya and Wanayasa, Purwakarta, West Java. Sampling sites was used as block with twice sampling at each location. Mangosteen fruit picked at the three levels of stages of maturity detected by color; a) Maturity-1: green red spots, b) Maturity-2: breaker red”cumolat” 10-25%, and c) Maturity-3: 25-50% red-purple spots. The maturity was based on the color of the assumed age of farmers as picking at 106, 108, and 110 days after bloom (DAB). Further mangosteen fruit was stored at ambient temperature 27-29 °C and at low temperature 9 ± 1 °C. Observations were made on physical and chemical properties at intervals of 0, 3, 6 days, until the samples were not accepted by panelis. Analysis of physical properties include withered sepals, weight loss, skin color of fruit, and mangosteen rind characteristics using scanning electronic microscope/SEM. Meanwhile, the chemical properties include vitamin C, total acid, and total soluble solids. The results showed that the stage maturity 108 days (maturity-2 break color 10-25%) has a 12 day shelf life with characteristics withered sepals 2.61; weight loss of 3.80%; vitamin C 60.01 mg/100 g, total soluble solids 17.35%, and 0.41% total acid is the best stage picking compared to other stage picking. The maturity of the mangosteen fruit picking 108 days after blooming (maturity-2) with these characteristics was expected to be used for determining the proper maturity for picking suitable for export.

Abstract

A variety of attempts have been made to reduce the dependence on petroleum raw materials based plastics which are limited supply and difficult to degrade, so it can cause the environment problems. Polyvinyl Alcohol/PVA, one of the water-soluble polymer, has good compatibility with fillers, i.e., nanocellulose addition, so it can resulted a composite films that are environmentally friendly and the mechanical properties close to conventional plastic. The objectives of research was to know the effect of pineapple nanocellulose fibers addition on the improvement of the mechanical properties of composite films based on polyvinyl alcohol. The method for manufactured of composite films using solution casting. A simple in a one-pot process was carried out by mixing of PVA solution in various concentration of pineapple nanocellulose fibers (10% - 50%) and glycerol with 2 levels (0% and 1%). Films observations were tensile strength, elongation, crystallinity, and morphology. The results shows that the addition of nanocellulose fibers 10-40% were effective in increasing tensile strength and elongation, but the higher addition (of up to 50%) resulted in decreased elongation. The addition of glycerol on the composite film tends to lower the tensile strength and elongation. This is supported by the XRD data showed that the addition of nanocelullose was also effective to improve the crystallinity properties of the films, but the properties of crystallinity decreased after adding glycerol. The best mechanical properties of composite film produced by the treatment on nanocellulose 40% addition and without glycerol.

Abstract

Limbah hortikultura berpotensi untuk dijadikan bahan antifungal. Penelitian sebelumnya menunjukkan bahwa ekstrak kulit mangga dengan pelarut etil asetat yang dievaporasi hingga menjadi ekstrak kental secara single mampu menghambat khamir Rhodotorula sp., mencapai 31 mm zona dimana nilai ini lebih besar dari benomyl 500 ppm yang hanya 10 mm. Untuk memperluas spektrum daya hambat, perlu dilakukan formulasi dengan bahan lain. Penelitian ini bertujuan untuk melakukan formulasi ekstrak biji atau kulit mangga dengan pengawet makanan komersial (natrium metabisulfit, kalium sorbat dan natrium benzoat) untuk menghasilkan pengawet yang berspektrum tinggi untuk preservasi buah mangga. Formulasi dilakukan melalui beberapa tahapan untuk menghasilkan konsentrasi dan perbandingan yang tepat. Formula antifungal terbaik berdasarkan uji plate adalah campuran dari ekstrak biji mangga : kalium sorbat 5% (75%:25%) dengan pengenceran 25%. Antifungal ini mampu menghambat kapang dan khamir perusak mangga sebagai berikut: Rhodotorulla sp. sebesar 47,2 mm, Penicillium sp. 41,3 mm, Fusarium sp. 43,6 mm dan Aspergillus niger sebesar 18,2 mm. Aplikasi pada buah mangga melalui penyemprotan menunjukkan hasil 0,2 skor kerusakan dan 2,7% susut bobot lebih baik dibanding kontrol pada penyimpanan hari ke-14 pada suhu 20oC±2oC
