Abstract

Makalah ini berisi tinjauan komprehensif terhadap literatur tentang proses penyangraian kopi dan pembentukan akrilamida sebagai hasil sampingan proses pengolahan biji kopi diterbitkan antara tahun 2008 hingga 2018. bagian besar penelitian bersifat empiris dan sebagian besar studi berfokus pada proses pengolahan kopi dan efek akrilamida pada kesehatan tubuh. Temuan penting lainnya, sebagian kajian menganggap bahwa kopi mampu meningkatkan kesehatan tubuh. Ulasan ini menyajikan pemahaman yang lebih baik tentang manfaat dan bahaya kopi serta pengaruh penyangraian terhadap mutu kopi yang dihasilkan. Tinjauan ini juga menyoroti tentang alat sangrai kopi yang relatif kurang dieksplorasi. Akademisi, peneliti dan kelompok tani dapat menggunakan hasil kajian ini sebagai pedoman dalam menyangrai kopi. Penyangraian dengan waktu dan suhu yang efektif dapat mengurangi pembentukan akrilamida pada kopi, namun perlu kajian literatur terbaru yang berkaitan dengan proses pengolahan kopi terutama pada proses penyangraian.

Abstract

Abstract. Base on previous studies showing that sugar palm fruit can be made as jam with the addition of Asian melastome fruit as a natural coloring. This sugar palm fruit jam product is packaged with jar and pouch packaging. shelf Life information for this product is unknown. The purpose of this study is to determine the rate of change in quality, critical parameters, and estimate the shelf life of sugar palm fruit jam with Arrhenius Model which is simulated at three storage temperature conditions (28⁰C, 38⁰C, and 48⁰C). Parameters observed during the storage process are water content, water activity (aw), pH, color (L), anthocyanin, and antioxidant activity (IC50). The results showed that the smallest activation energy value was used to determine product shelf life, it is color parameters (L) (first order reaction) with linear regression y = -4715.x + 9,787 on jar bottle packaging and y = -2021.x + 1,387 on packaging pouch. The age of storing sugar palm fruit jam with jar bottles is 93 days at 28⁰C and on the packaging pouch for 40 days at 28⁰C.

Abstract

The purpose of this study were to determine the effect of temperature and roasting duration on physical characteristics and quality of arabica coffee sensory,: find out the best temperature and roasting duration treatmen to physical characteristics and quality of arabica coffee sensory. This study used a factorial complete randomized design with two factors (200°C, 220°C and 240°C) and duration of roasting (12, 15, and 18 minutes). The variables observed in this study were rendemen (sucrose content of sugar cane crop or sample), water content, color value, acidity and sensory test of arabica coffee. The results showed that temperature and duration of roasting had effect on rendemen, water content, color value, acidity, flavor, taste and color of arabica coffee. The temperature of 220 ° C with 12 minutes of roasting is produceed the best physical characteristics and sensory quality of Singgalang arabica coffee, with 88.1% of rendemen, 1.23% of water content (bb), different color L (Lightness) 6,07, acidity 5.81, scent score 3.5), taste score value of 3.2, color score 3.6.

Abstract

One of the types of coffee cultivated in Solok Regency is Arabica Coffee (Coffea Arabica L). The quality of the coffee produced can be influenced by the proper harvesting and post-harvest process so as to produce ground coffee with good quality. This research is done by the method of observation, descriptive, and hedonic test. Ground coffee produced in Solok Regency has a semi-mechanical harvesting process while the post-harvest process begins with the release of the skin and meat of the fruit, subsequent drying, and release of the skin of horns, sorting and grading, roasted, milling and packaging. This research aims to study the processing and quality of Arabica Ground Coffee in Solok Regency.
