Abstract

Penambahan sorbitol dalam biji kopi ditujukan untuk meningkatkan aroma dan antioksidan setelah disangrai. Penelitian ini bertujuan untuk mengidentifikasi perubahan fisik pada biji kopi robusta selama penyangraian. Parameter yang diamati adalah suhu dan waktu first crack, second crack, akhir proses penyangraian, dan munculnya asap. Konsentrasi sorbitol terdiri dari 0%, 5% dan 10% (b/b). Sedangkan jenis penyangraian terdiri dari light, medium dan dark. Hasil penelitian menunjukkan bahwa penambahan sorbitol dan jenis penyangraian berpengaruh terhadap sebagian besar parameter fisik selama penyangraian. Peningkatan konsentrasi sorbitol menyebabkan penurunan suhu second crack dan suhu munculnya asap. Namun seluruh parameter waktu mengalami kenaikan. Tingkat penyangraian yang semakin meningkat menyebabkan kenaikan waktu seluruh parameter. Meskipun demikian, suhu seluruh parameter cenderung berfluktuasi

Abstract

The two most widely traded coffee varieties in the world are arabica and robusta. Consumption of these two varieties will increase the intake of bioactive compounds in the human body. However, the influence of consumption of both coffee varieties on blood sugar response and changes in the glycemic index of sugar added when consuming coffee has not been studied. The aim of this research to study the effect of coffee varieties on bioactive compound content, voluntary blood glucose response, and changes in the glycemic index value of sugar when consumed together with coffee. This study was designed with the treatment of arabica and robusta coffee varieties. Coffee roasting was carried out at the level of vienna roasting. Analysis of bioactive compounds was carried out on the content of phenol compounds. Analysis of blood sugar and glycemic index responses using volunteers. Coffee was brewed at a dose of 12 grams per 100 ml of water at 98ᵒC. Sugar added 50 grams. The results showed that arabica contained phenol compounds greater than robusta. It was also prove that consuming coffee can reduce blood glucose response compared to consuming glucose. Decreased blood glucose response of arabica is greater than robusta. Drinking coffee mixed with sugar or with eating bread can reduce the sugar or bread glycemic index value. Decrease in sugar or bread glycemic index value in arabica consumption was greater than robusta. Conclusion, coffee consumption can reduce the response of blood sugar and glycemic index of sugar added to drinks and bread glycemic index because of the content of its bioactive compounds.

Abstract

The demand for coffee is currently increasing. Apart from health reasons, it is also because of life style or lifestyle. This includes the demand for civet coffee. Increasing demand both from within the country and abroad due to the unique taste. Increasing luwak production can be done by producing coffee using luwak tangkar. In this study, civets were used individually and given coffee once in the afternoon. The rest is given rice, bananas and meat. This study aims to determine the taste of Temanggung civet and natural robusta coffee. This study used 25 untrained panelists. From this research, Robusta Temanggung which was processed using fermented fermented luwak for 12 hours showed sensoryly that untrained panelists could notice a striking difference between the two. The difference lies in the medium body, higher acidity, and lower bitterness in civet coffee.

Abstract

Penelitian ini untuk mengetahui pengaruh pengecilan ukuran biji kara benguk (Mucuna pruriens,L) dan lamafermentasi terhadap kadar asam fitat dan kadar protein pada pembuatan tempe kara benguk (Mucunapruriens,L). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola faktorial yangterdiri dari dua faktor yaitu variasi pengecilan ukuran (3 macam) serta variasi lama fermentasi (5 macam).Hasil penelitian menunjukkan setiap 12 jam waktu fermentasi untuk ketiga jenis ukuran biji kara benguk, kadarasam fitat terendah dan kadar protein terlarut tertinggi didapatkan pada tempe kara benguk biji giling. Padafermentasi 36 jam untuk ketiga jenis ukuran biji diperoleh asam fitat terendah selama fermentasi yaitu 3,32mg/g; 1,98 mgr/g dan 1,16 mg/g. Kadar protein terlarut tertinggi selama fermentasi juga diperoleh padafermentasi 36 jam yaitu 19,51mg/g; 23,73 mg/g dan 24,89 mg/g.Berdasarkan hasil penelitian ini dapat disimpulkan bahwa lama fermentasi dan ukuran biji kara bengukberpengaruh pada kadar asam fitat dan kadar protein terlarut pada tempe kara benguk. Semakin lama fermentasitempe kara benguk maka kadar asam fitat semakin rendah dan kadar protein terlarut semakin tinggi. Semakinkecil ukuran biji tempe kara benguk, maka kadar asam fitat semakin rendah dan kadar protein terlarutnyasemakin tinggi. Tempe kara benguk biji giling fermentasi 36 memiliki kadar asam fitat terendah dan kadarprotein terlarut tertinggi dari semua sampel dengan variasi lama fermentasi dan pengecilan ukuran. Waktuoptimal fermentasi yaitu 36 jam karena untuk pengujian protein terlarut dan asam fitat tidak berbeda nyatatermasuk teksturnya sudah cukup kompak.

Abstract

Ginger coffee drinks have been in great demand by consumers, and instant ginger coffee sachets have been circulating in the market. Ginger coffee effervescent tablets will be an alternative product to increase coffee consumption, and the industry can apply. This research aimed to study the sensory profile of ginger coffee effervescent tablets and their solutions made from a different concentrations of ginger coffee powder and types of organic acids. This study used a factorial design with two factors. The first factor was the concentration of 30 % and 50 % of ginger coffee powder. The second factor was the type of organic acid which consists of tartaric acid, malic acid, and a combination of both acids. A descriptive sensory test was conducted by using trained panelists. The results showed that the increasing concentration of ginger coffee powder in the formulation had a significant effect on the sensory profile of the ginger coffee tablet and effervescent solution, especially the darker and browner colors. In contrast, the taste and aroma weren’t changed significantly. The difference in organic acids in the formulation did not cause significant differences in the sensory profile of the ginger coffee effervescent solution and tablets. In general, the dissolution of tablets in water into an effervescent solution will increase the color sensory profile but not the aroma profile.
