Abstract

Proses pemanasan yang berlebih pada pengolahan makanan dapat memicu pembentukan akrilamida. Akrilamida merupakan zat beracun yang bersifat karsinogenik pada manusia. Salah satu pencegahan untuk mereduksi akrilamida yaitu dengan penambahan enzim L-asparaginase. Enzim L-Asparaginase dapat mencegah pembentukan akrilamida dengan mengkonversi asam amino L-Asparagin sebagai prekusornya menjadi bentuk asam amino lain yaitu asam L-Aspartat. L-Asparaginase dapat ditemukan pada berbagai organisme salah satunya adalah bawang putih. Tujuan dari penelitian ini adalah mampu mengisolasi dan mengetahui karakter optimum L-Asparaginase dari bawang putih (Allium sativum). Enzim L-Asparaginase dari bawang putih diperoleh melalui beberapa tahap. Tahap pertama yaitu isolasi L-Asparaginase dari bawang putih dan pemurnian melalui pengendapan dengan amonium sulfat dan dialisis. Tahap kedua yaitu uji aktivitas spesifik dan karakterisasi L-Asparaginase dengan cara menghitung jumlah amonia yang terbentuk menggunakan pereaksi Nessler dan memperoleh kadar protein total dengan metode Lowry. Hasil penelitian ini menunjukkan aktivitas spesifik tertinggi LAsparaginase dari bawang putih pada fraksi 5 (80-100%) yaitu 1054,444 U/mg protein. Kondisi optimum L-Asparaginase bebas yaitu pada suhu 37°C, pH 8,6 dan waktu inkubasi selama 30 menit.

Abstract

Koro-koroan dapat diolah menjadi tempe melalui proses fermentasi dengan Rhizopus sp.. Tempe koro berpotensi sebagai pangan fungsional antihipertensi karena menghasilkan peptide ACE inhibitor. Enzim protease memotong protein koro menjadi peptide yang lebih kecil pada proses fermentasi. Setelah melalui proses pencernaan, tempe koro tetap berpotensi sebagai ACE inhibitor karena terjadi proses hidrolisis oleh enzim pencernaan sehingga terjadi pemotongan peptide menjadi peptide yang lebih sederhana dan asam amino. Peptida dengan berat molekul kecil memiliki aktivitas penghambatan ACE yang lebih besar. Proses fermentasi dan hidrolisis pada sistem pencernaan dapat menghasilkan peptide dengan berat molekul kecil sehingga potensi ACE inhibiornya lebih besar.

Abstract

Snacks are often consumed by people to temporarily relieve hunger. These snacks are usually high in sugar and fat and low in fiber. One of the healthy snacks consumed is a snack bar made from local food. In this training, developing a snack bar based on local food ingredients that is low in calories and high in fiber, namely a snack bar based on purple sweet potatoes flour. The purpose of this training is to introduce the community to product diversification using local food from purple sweet potatoes which can be processed into healthy snacks and basic skills on how to make the snack bar. The methods used in this training are lectures, demonstrations and questions and answers. The stages of implementing the activity are an explanation of local food, using purple sweet potato as a basic ingredient for healthy snacks. Next, the practice of making snack bars with the basic ingredients of purple sweet potato flour, peanuts and crispy rice. The results of the evaluation of the snack bar making training, namely the response of the training participants were very satisfied and enthusiastic in participating in this activity because participants could add new insights and knowledge in terms of local food snack bars. In addition, the training participants also got new business ideas to be developed in healthy snack culinary.

Abstract

Cendol is one of the popular drinks in Indonesia which is made from flour with incomplete nutritional content, so it is necessary to modify the formulation of cendol by adding tilapia fish meat and coffee grounds to complement the nutritional value of cendol products. The purpose of this study was to determine the effect of the addition of coffee grounds on consumer acceptance and the nutritional value of tilapia cendol products. This study used a completely randomized design (CRD), with 4 treatments adding coffee powder 0 g, 4 g, 6 g, and 8 g. The results showed that the addition of coffee grounds had an effect on the hedonic results of tilapia cendol. The best cendol according to consumer acceptance based on hedonic code K2 results with the addition of 6 g coffee powder with a moisture content of 65.34%, ash content of 0.48%, fat content of 0.52%, protein content of 11.13%, and carbohydrate content of 23 .53%.
