Pemanfaatan minyak buah merah sebagai bahan tambahan pangan masih terbatas. Penelitian sebelumnya menghasilkan serbuk minyak buah merah yang menggumpal dan mempunyai kelarutan yang rendah dalam fase cair. Penelitian ini bertujuan mengembangkan teknologi dan formulasi pembuatan serbuk minyak buah merah yang tidak menggumpal serta mempunyai kelarutan dalam air dan kandungan beta karoten yang cukup tinggi. Metode penelitian dilakukan dengan penambahan proses homogenisasi sebelum proses pengeringan semprot dan variasi bahan pengisi (maltodekstrin dan siklodekstrin). Hasil penelitian menunjukkan mutu serbuk minyak buah merah dipengaruhi oleh proses homogenisasi menggunakan emulsifier (lesitin) sebelum dilakukan pengeringan dengan alat pengering semprot. Serbuk minyak yang dihasilkan berbentuk kristal, berwarna merah oranye dan teksturnya tidak menggumpal. Kadar β-karoten tertinggi didapat pada serbuk minyak buah merah dengan penambahan siklodekstrin (1:2), yaitu 5,97 mg/kg. Rendemen berkisar antara 16,5 – 29,8 % dan kelarutan berkisar antara 49,13 sampai 89,32%. Sedangkan Analisis morfologi menggunakan SEM memperlihatkan bahwa serbuk minyak buah merah berbentuk bulat tidak beraturan, tersebar secara merata dan tidak membentuk flokulasi dengan ukuran 20-70 µm.

Antioxidant are subtances that when present in food or in the body at low concentration compared to that of an oxidizable substrate markedly delay or prevent the oxidation of that substrate. The mechanism by which antioxidants protect food from oxidation is by scavenging of free radicals via donation of an electron or a hydrogen atom,or by deactivation of metal ions and singlet oxygen. Natually occuring inhibitors of oxidation in food generally originate from plant-based materials.Antioxydant can be classified into groups based on how they work and where they are found.There have been a number of assay mathods developed to measure the capacity of antioxidant as pure compounds or in extract.These methods foccus on different mechanisms of the antioxidant such scavenging of oxygen and hydroxyl radicals,reduction of lipid peroxil radicals,chelation of metal ions,or inhibition of lipid peroxidation.The very common methods used were:ORAC,OSI,DPPH ,and TEAC.There are three principle,techniques that may be used to extract naturally occuring antioxidant:extraction using solvent solid-phase extraction,and supercritial carbondioxida extraction

Study on Extraction of Theobromine from Cacao seed has been conducted. The study is aimed at evaluating the extraction of theobromine effectiveness using Pavia Method and the modification of Pavia Method. The modification of Pavia Method was based on variation of MgO level and variation of organic solvent used. The variation of MgO level were 6 gr, 3 gr, and 0 gr, and the variation of organic solvent used were etanol, chloroform, and etyl acetate. The result of study showed that there was no significance influence of variation of MgO level on the weight and concentration of theobromine extracted. While the variation of organic solvent used showed significance influence to the weight and concentration of theobromine extracted. The best extraction result was obtained when using ethanol when using ethanol as an organic solvent.

Limbah organik pasar merupakan sumber biomassa yang cukup penting untuk dimanfaatkan menjadi bioetanol. Salah satu permasalahan dalam produksi bioethanol dari biomassa adalah adanya kandungan lignin yang sulit untuk diuraikan. Penelitian ini bertujuan untuk mempelajari proses delignifikasi limbah pasar untuk produksi bioetanol. Tahapan proses produksi bioetanol yang diamati meliputi proses delignifikasi serta hidrolisis enzimatis dan fermentasi. Hasil penelitian menunjukkan proses delignifikasi pada sabut kelapa dapat menurunkan kadar lignin sebesar 21,64 %. Proses fermentasi simultan menggunakan Trichoderma pada sabut kelapa menghasilkan bioetanol 0,07 % pada hari ke-4 dan hari ke-5. Fermentasi simultan menggunakan P. nalgiovense S11, menghasilkan bioetanol mulai pada hari ke-3, dan cenderung terjadi peningkatan sampai hari ke-5. Fermentasi simultan menggunakan P. nalgiovense S11 menghasilkan kadar bioetanol, untuk sabut kelapa maksimum 1,07%; kulit jagung maksimum 1%, dan tongkol jagung maksimum 5,51 %. Pada fermentasi terpisah menggunakan P. nalgiovense S11, pembentukan bioetanol untuk kulit jagung dan jerami terjadi pada hari ke-4 dan ke-5 maksimum 0,8%. Secara keseluruhan, bioetanol yang terbentuk dari proses fermentasi simultan lebih besar daripada proses fermentasi terpisah.

Cacao beans processing into product may affect active compound contents in the final products, especially catechin and epicatechin. Temperature treatments during cacao processing can induce epimerization reaction of (-)-epicatechin to be (-)-catechin. Therefore, catechin and epicatechin ratio in the samples would be change. The aim of the was to know imfluence during cacao beans processing, especially cathechin and epicatechin concentration. Samples taken during the process were cacao nib, cacao mass, cacao powder, and butter. Analysis of catechin and epicatechin in samples was carried out by liquid chromatography mass spectrometry. Analytical for catechin were using mobile phase A (0.1 %formic acid in deionized water) and mobile phase B (acetonitril-methanol = 50:50) at flow rate of 0.5 ml/min. gradient elution were set at 0 minutes (10%B), 15 minutes (35%B), 20 minutes (40%B), 30 minutes (50% B), 35 minutes (60% B), and 35.1 minutes (105 B). Mass sprectrometer was set at ESI voltage (-) 3500 volt, desolvation temperature 300 oC, nubelizer pressure 50 psi, desolvation gas 10L/min, and fragmentor voltage (-) 160 volt. Results of the research showed that of catechin and cacao nib, cacao mass and cacao powder were 1:21,7; 1:20,0; and respectively. Heat treatments during cacao mass processing sowed a decrease tendency of catechin and epicatechin concentrations.

A flavor is a substance which may be a single chemical entity, or a blend of chemicals of natural or synthetic origin whose primary purpose is to provide all or part of the particular flavor effect to any food or other product take in the mouth. A vast array of compounds may be responsible for the aroma of the food products, such as alcohols,aldehydes, eesters,dicarbonyls, short to medium-chain free fatty acids, methyls ketones, lactones, phenolic compounds.At present, due to the high cost or lack of availability of natural flavor extracts, most commercial flavorants are chemically synthesized, mostly from petroleum-derived precursors. Because chemical synthesis often uses environmentally unfreiendly production processes, it is desirable to switch to bioproduction, including the extraction from natural source, de novo microbial process (fermentation ), and bioconversion of natural precursos using micro-organisms or isolated enzymes.Natural flavour compounds usually exist at very low concentratiuons. To recover the flavour compounds at a purity of interest for practicial applications , flash distillation and adsorption are being used degradation as wellas high energy cosumption. These challenges inspire and encourage the development of a safer and more economical separation technique, such as: pervaporation techniques, head-space techniques, and supercritical fluid extraction.The scope of this paper covers the development in the bioflavor production, sources, isolation and recovery techniques.This paper is aimed at providing the information related on natural flavor issue which can be used as an additional information to the researcher on the natural falvor industry.
