Abstract

Traditional food products are no longer attractive to the public, so it needs innovation to ensure that the products have a functional value. The aim of this research is to produce fortified cornmeal with kersen (Muntingia calabura L.) leaf extract which has high antioxidant activity and consumer demand of organoleptics. This research used a completely randomized design with single factor at 6 treatment levels, soaking grits of corn on cherry extract with 0%; 10%; 20%; 30%; 40%; and 50% concentrations. The results of nutrient analysis showed that protein contents ranged from 7.59% – 8.93%; fat 0.53%–0.96%; ash content 0.05%–0.12%; water content 11.6%–13.37%; and carbohydrate 77.24%–78.91%. The result of antioxidant activity showed that the higher concentration of kersen leaf extract added the higher also the antioxidant activity of fortified cornmeal, between 11.85–36.17%. Based on panelists’ organoleptic test, most gave neutral response to like slightly for color, texture, aroma and overall grits, while for the panelists, while for taste they gave dislike slightly response.

Abstract

Ikan cakalang (Katsuwonus Pelamis) merupakan salah satu jenis ikan yang banyak diolah oleh masyarakat, terutama masyarakat Gorontalo. Pemanfaatan ikan cakalang terutama dagingnya diolah menjadi buah tangan seperti abon dan cakalang fufu dengan cara pengasapan. Limbah ikan berupa jeroan dan tulang belum dimanfaatkan. Dalam penelitian ini dilakukan pembuatan bakasang yang memanfaatkan jeroan ikan cakalang dengan penambahan ekstrak asam jawa dan variasi lama fermentasi. Penelitian ini adalah penelitian action research yang menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal dengan variasi lama fermentasi; (3 hari), (6 hari), (9 hari). Hasil penelitian menunjukkan bahwa lama fermentasi bakasang ikan cakalang memberikan pengaruh nyata terhadap kadar TVB-N, kadar histamin, dan kadar pH, sedangkan pada kadar air tidak berpengaruh nyata terhadap lama fermentasi bakasang. Proses fermentasi ini juga menghasilkan pertumbuhan bakteri asam laktat (BAL). Total pertumbuhan BAL dan Kapang tertinggi dihasilkan dari lama fermentasi 3 hari (P1). Hasil uji organoleptik bakasang ikan cakalang dengan parameter warna, aroma dan tekstur menunjukkan bahwa panelis memilih rentang skor untuk warna 3,90 – 6,13 (agak tidak suka sampai suka), aroma dengan skor 3,63 – 5,07 (agak tidak suka sampai agak suka), dan tekstur dengan skor 3,20 – 5,13 (agak tidak suka sampai agak suka)..

Abstract

Waxy corn (AJU1) is widely cultivated in Gorontalo Province, but its utilization is limited to corn on cobs.  A potential diversified product of processed waxy corn to be developed is waxy corn starch. One simple method to improve the functional properties of waxy corn starch is fermentation. This study aimed to determine the effect of different fermentation conditions and fermentation times on the gelatinization profile and functional properties of waxy  corn starch. The research method used a completely randomized factorial design with two treatment factors namely fermentation conditions (aerobic and anaerobic) and fermentation time (3, 6, and 9 days).  Results showed that the fermentation conditions significantly affected property of waxy corn starch.  During fermentation, there was a change in the number of cells of lactic acid bacteria, yeast, and mold. The gelatinization profile of  fermented waxy corn starch was to have resistant to stirring and high temperatures and reduced its retrogradation tendency. The fermentation process also changed the functional properties of glutinous corn starch, namely an increase in solubility, swelling, and acidity (decrease in pH).Keywords: aerobic, anaerobic, fermentation, starch, glutinous corn [AJU1]
