Abstract

Coffee is a beverage that is widely consumed around the world. Proper packaging and storage temperature may extend shelf life of ground coffee. The study aimed to analyze the shelf life of ground Arabica coffee stored in different packaging types and temperature, conducted at smallholder coffee plantations in Garut Regency and the Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, from June to August 2018. A completely randomized design in factorial was used with 3 factors and 2 replications. The first factor was the packaging type  which consisted of 3 types: thick alumunium  foil 65m (AF65), thick alumunium  foil 130m (AF130), and thick lamination 114m (L144). The second factor was the storage temperature which consisted of 3 levels: 25 oC, 35 oC, and 45 oC, while the third factor was the storage period which consisted of 5 levels: coffee unstored, and coffee stored for 2 weeks, 4 weeks, 6 weeks, and 8 weeks. The variables observed were the water and fat content, and the analysis of shelf life was carried out using the ASLT (Accelerated Shelf Life Test) method. The results showed that during storage, the water content increased, whereas the fat content decreased. Fat content is a critical variable in determining the shelf life of coffee. The coffee in AF130 packaging has longer shelf life than in AF65 and L144. To extend the shelf life of coffee packaged in AF130 and L144 is best kept at 45 oC whereas coffee in AF65 packaging  is ideally at 25 oC.

Abstract

Robusta coffee is the most widely cultivated coffee in Indonesia. However, flavor quality of coffee is low due to improper harvesting and postharvest handling by farmers. Flavor quality mostly determined by fruit maturity level, fermentation and roasting time. The research aimed to investigate the effect of fruit maturity level, fermentation and roasting time on the physico-chemical characteristics of Robusta coffee. The research was conducted at Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), from May to July 2017, used a completely ranndomized block design with 3 factors. The first factor was fruit maturity level (red and reddish yellow), second factor was bean fermentation (24 and 36 hours) and the third factor was roasting time (10 and 13 minutes). Physical quality covered percentage of live insects, moisture content, foreign materials and amount of defective beans. Chemical quality covered moisture content, ash, fat, protein, caffeine and acidity. The results showed that physical quality of fermented beans i.e. moisture content and amount of defective beans were affected by fruit maturity level and fermentation time, while foreign materials is affected by the interaction between these two factors. Chemical quality of coffee i.e. fat and caffeine content were affected by the interaction between fruit maturity level, and fermentation and roasting time. Water and protein content were affected by interaction between fruit maturity level and fermentation time, and interaction between fruit maturity level and roasting time. The ash content is affected by the roasting time, whereas pH is affected by fermentation time and roasting time.

Abstract

Kakao salah satu tanaman perkebunan penghasil devisa negara, karena Indonesia merupakan produsen terbesar ketiga dunia. Kakao Indonesia umumnya memiliki mutu lebih rendah, salah satunya disebabkan oleh tidak dilakukannya proses fermentasi. Fermentasi merupakan perubahan kimia pada zat organik yang timbul akibat enzim mikroba. Mikroba jenis Bacillus dan jamur filamenteus akan menguraikan pulpa sehingga terbentuk aroma cokelat. Proses fermentasi dapat dilakukan dengan beragam metode, seperti ditumpuk atau menggunakan wadah kotak. Rata-rata proses fermentasi membutuhkan waktu sekitar 5-6 hari. Mutu fisik biji kakao fermentasi sudah diatur dalam SNI 2323-2008. Beberapa penelitian yang terkait perbedaan mutu fisik biji kakao hasil fermentasi dan tidak fermentasi terlihat jelas pada warna, aroma dan tekstur biji pada saat dilakukan uji belah. Selain itu, kandungan lemak dan nilai pH pada biji kakao hasil fermentasi lebih tinggi bila dibandingkan dengan tanpa fermentasi. Senyawa volatil yang lazim ditemukan pada kakao merupakan golongan aldehid, keton, ester, alkohol, asam, pirazin dan senyawa lainnya. Senyawa golongan aldehid yang memberikan flavor cokelat seperti 2-methylbutanal meningkat selama fermentasi. Rerata kandungan senyawa volatil yang memberikan aroma yang disukai meningkat selama bertambahnya waktu fermentasi.
