Abstract

Coklat merupakan makanan yang terbuat dari campulan gula dan lemak yang banyak disukai masyarakat. Parameter utama yang harus diperhatikan pada pembuatan coklat batang adalah hasil pengujian hedonik atau tingkat penerimaan konsumen terhadap produk, meliputi parameter rasa, warna, kenampakan, tekstur dan aroma. Selain itu sifat fisik utama yang harus diperhatikan adalah ada dan tidaknya kemunculan fat bloom atau bercak-bercak putih pada permukaan pada permukaan coklat batang. Bahan yang digunakan dalam penelitian ini adalah daun mangrove jenis Rhizophora apiculata (RA), Avicennia officinalis (AO), dan Avicennia marina (AM). Penelitian menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan penambahan ekstrak daun mangrove dari spesies yang berbeda yaitu Rhizophora apiculata, Avicennia officinalis, dan Avicennia marina, dan kontrol (tanpa penambahan serbuk daun mangrove) diulang 3 waktu. Pengujian hedonik dilakukan pada coklat dilakukan pada hari penyimpanan ke 0, 7, dan 14 pada suhu kamar. Berdasarkan hasil pengujian hedonik dan antioksidan menunjukkan bahwa perlakuan pemberian ekstrak daun mangrove spesies Rhizopora apiculata (RA) merupakan perlakuan terbaik karena memiliki aktivitas antioksidan paling tinggi serta uji hedonik yang paling tinggi dibandingkan dengan perlakuan lainnya. Selain itu perlakuan (RA) dapat menghambat terbentuknya fat bloom dalam kurun waktu 14 hari masa simpan.

Abstract

Fisheries and marine sector is one of the potential sectors in Indragiri Hilir district, Riau. Local fishermen make efforts to preserve the catch by salting it. Although salt can extend product shelf life, there are still many salted fish producers that add formaldehyde and borax to reduce production costs. The addition of formaldehyde and borax is carried out with the aim of extending product shelf life so that producers do not lose. The aim of this study was to determine the presence of formalin and borax content in salted fish products in several markets in Tembilahan. The sampling method in this study was simple random sampling by taking three different samples of salted fish, namely salted belukang, salted kembung, and salted gulama in three different markets in Tembilahan. Samples were tested for formalin and borax using test kit. The results of the qualitative formalin content test showed that from 9 samples of salted fish from several Tembilahan markets, there were 5 positives samples containing formaldehyde. The five samples were salted salted fish belukang, salted fish kembung, salted fish gulama from central market, and salted fish gulama and salted fish kembung from Parit 11 market. In the other hand, the salted fish samples were also tested qualitatively for borax content test. The qualitative test results of borax on 9 samples from several markets in Tembilahan showed no color change on the turmeric paper after immersion in the sample solution. This indicates that all salted fish samples is negative for borax content.
