Abstract

This study aimed to produce functional food products with the main ingredient of pumpkin and olein fraction of red palm oil (OF-RPO). This research was conducted in two stages. The first was to analyze consumer acceptance where a Completely Randomized Design was used with one factor. The factor was the composition of pumpkin and OF-RPO levelled as follow: 100:0, 95:5, 90:10, 85:15, 80:20, and 0:100 (v/v). In the second stage, analyses of carotenoids using HPLC, FFA, pH, vitamin C, and peroxide values were carried out on selected formula (mixture of pumpkin and OF-RPO), formula with 100 mL of pumpkin, formula with 100 mL of OF-RPO, and negative control (without pumpkin and OF-RPO), before and after the storage period of two months, except for HPLC analysis. The best formula based on acceptance test was a composition of 90 mL pumpkin and 10 mL OF-RPO was further diluted 1:4 (v/v). Characteristics of the product were sweet, sour, not bitter, not grassy, and not rancid. The emulsion product contains trans-β-carotene at 141.65±0.47 mg/L, equivalent to 237 UI activity of vitamin A/mL. The content of trans-β-carotene was found at the highest (341.83 mg/L) from the pumpkin juice, while the OF-RPO had the lowest trans-β-carotene content (41.2 mg/L). Product was acidic with a pH of 3.6±0.1 and with vitamin C content of 13.2±1.2 mg/100 g of product. Acidity and vitamin C levels tended to remain stable during the storage period for two months. Peroxide value of the emulsion product was at 0.8 mEq oxygen/kg. The FFAs were in the range of 1.59 to 1.73% and they also did not change significantly after storage for two months.

Abstract

Studies on the potential of kapas banana (Musa comiculata) flour as resistant starch source were carried out through analysis of resistant starch content and starch digestibility on the native and modified banana flour. Native banana flour was prepared by drying the banana slice, ground and passed through an 80 mesh screen. Modified banana flour was produced by spontaneous fermentation (roo m temperature; 0,2, 24 and 36 ) and a toclaving ( 2  ̊C; 0, 5, 30 and 45 min) of t e banana slices before drying process. The modification processes influenced the amount of resistant starch and its digestibility. Spontaneous fermentation up to 12 h and autoclaving up to 30 min increased the resistant starch content and digestibility of kapas banana flour produced.

Abstract

Rebung merupakan batang bambu muda yang baru muncul dari perrmukaan dasar rumpun dan rhizorme. Rebung mempunyai banyak kelebihan antara lain: sebagai tepung alternatif, sebagai bahan baku pangan kaya serat, disversifikasi pangan lokal, dan lebih tahan disimpan sehingga penting sebagai penyedia bahan baku industri. Penelitian dilakukan untuk mengetahui sifat fisiko-kimia tepung rebung betung. Penelitian ini merupakan penelitian faktor tunggal yang disusun dalam Rancangan Acak Lengkap (RAL) dengan 4 Ulangan. Faktor yang diteliti yaitu 5 variasi perlakuan waktu fermentasi yakni 0, 12, 24, 36 jam, dan 48 jam. Penelitian menunjukkan bahwa berbagai perlakuan waktu fermentasi spontan berpengaruh nyata terhadap rata-rata kadar air, kadar abu, rendemen, serat kasar, kapasitas penyerapan air, densitas kamba, swelling volume dan kelarutan, namun tidak berpengaruh nyata terhadap kapasitas penyerapan minyak. Nilai kadar air 4,20-9,40%, kadar abu 1,90-8,25%, rendemen 0,84-3,43%, serat kasar 5,87-15,5%, kapasitas penyerapan air 9,71-9,87 g g-1 bk, kapasitas penyerapan minyak 9,71-9,87 g g-1 bk, densitas kamba 1,53-3,40% g/ml, swelling volume 5,06-6,78 g g-1 bk, dan kelarutan 1,31-2,61 g g-1 bk. Waktu fermentasi 48 jam merupakan perlakuan yang menghasilkan tepung dengan sifat fisik dan kimia.

Abstract

Crackers merupakan salah satu camilan yang digemari oleh kalangan masyarakat yang umumnya terbuat dari bahan dasar tepung terigu. Saat ini impor gandum di Indonesia cukup tinggi, sehingga salah satu cara untuk mengurangi ketergantungan impor gandum adalah dengan substitusi terigu menggunakan jenis tepung lain. Dalam penelitian ini tepung talas belitung (TB) dan tepung wortel (TW) digunakan sebagai substitusi tepung terigu (TT) dalam pembuatan crackers. Tujuan penelitian ini adalah menentukan formulasi tepung komposit (TT:TB:TW) terhadap sifat kimia, fisik, dan organoleptik crackers. Penelitian ini menggunakan Rancangan Acak Lengkap dengan formulasi TT:TB:TW adalah 60%:20%:20%, 60%:25%:15%, 60%:30%:10%, dan 60%:35%:5%, masing-masing diulang empat kali. Dibuat juga perlakuan kontrol dengan bahan TT 100%. Hasil penelitian menunjukkan bahwa formula tepung berpengaruh nyata terhadap semua sifat kimia crackers, satu sifat fisik, yaitu kekerasan, dan tiga atribut sifat organoleptik hedonik (warna, aroma, dan tekstur). Berdasarkan respons organoleptik, crackers terbaik dihasilkan dari formula tepung 60%:30%:10%. Crackers tersebut mempunyai nilai warna 0,17, kekerasan 1,75 kgf, kerenyahan 3,38 mm, kadar air 3,32%, kadar abu 3,57%, kadar protein 9,40%, kadar lemak 18,49%, kadar karbohidrat 65,22%, dan kadar β-karoten 26,29 mg/gram.

Abstract

Quality and shelf life degradation are problems in minimally processed horticultural products (fresh-cut). Edible coating is one way to protect the product from the quality degradation process. Edible coating is a thin layer of edible material applied to the product's surface. One of the potential materials for forming edible films is sago starch. Sago starch-based edible coating has the disadvantage of low mechanical strength and a barrier to water vapor. The addition of bacterial cellulose (BC) filler functions as a physical barrier to vapor and gas while improving its mechanical strength. The treatments applied to fresh-cut Malang apples were without edible coating, with sago edible coating and sago edible coating plus BC. The application of sago edible coating with the addition of BC was able to reduce changes in weight loss by up to 66.4%, and hardness by up to 32.50%, as well as maintaining the total dissolved solids, color (brightness), and acidity level (pH) of fresh-cut apples until the 8th day of storage. Adding BC to the edible coating formula provided a better protective effect than edible coating without BC.

Abstract

Margarin umumnya diproduksi dari lemak tumbuhan. Margarin sering digunakan dalam produk pangan untuk meningkatkan nilai gizi, memberikan aroma spesifik dan rasa yang enak. Penggunaan fraksi olein-stearin dan ekstrak labu kuning merupakan upaya diversifikasi untuk menghasilkan margarin bernilai tambah. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh rasio fraksi olein dan stearin terhadap penerimaan sifat sensoris margarin. Penelitian ini menggunakan Rancangan Acak Lengkap non faktorial dengan 5 perlakuan proporsi fraksi olein dan stearin yaitu 5:95, 10:90, 15:85, 20:80, 25:75. Hasil penelitian menunjukkan  proporsi fraksi olein dan stearin dengan penambahan sari labu kuning memberikan pengaruh nyata terhadap uji hedonik warna, aroma, rasa, tekstur dan uji mutu hedonik warna, aroma, rasa, dan tekstur margarin. Margarin dengan karakteristik terbaik diperoleh dari penggunaan fraksi olein dan stearin (5:95).

Abstract

Jelai (Coix lacryma-jobi L.) is a plant that produces seeds and can be consumed like cereals. The high carbohydrate content makes jelai suitable for processing into flour. Native jelai flour has the disadvantages of being susceptible to retrogradation and syneresis, not resistant to changes in pH, temperature, or mechanical treatment so that modifications need to be made to improve its characteristics, one of which is ultrasonication. This study aims to determine the effect of ultrasonication time on the physicochemical and functional characteristics of jelai flour. The results showed that ultrasonication time had a significant effect on colour analysis a* and b* of modified jelai flour and no significant effect on water absorption capacity, amylose content, and viscosity. The highest a* colour analysis value was obtained from the 60-minute ultrasonication time treatment of 2.05 and the highest b* value was obtained from the 50-minute ultrasonication time of 9.58. The increase in a* and b* values is due to the high heating temperature during ultrasonication time which can change the chemical composition of flour which affects the colour.
