Abstract

Currently, the consumption of broiler-chicken meat increases up to 3.7510 kg/cap/year. This condition is due to the increasing of population growth and food businesses which use chicken meat. On the other hand, the chicken meat contains of high fat, thus easily oxidized and resulted in free radicals and off- flavor. Chicken meat is widely used as meatball that is processed through the stage of meat-milling and boiling which triggers fat oxidation. Therefore, an antioxidant is needed to inhibit oxidation. Aloevera contains flavonoid compounds that could scavange free radicals. The objective of this research was to optimize the addition of aloe vera gel in the chicken meatball to obtain high antioxidant effect and acceptable product. Considering its high water content (> 98%), in this study aloe vera gel was added as an ice-substitution in the making of meatball. The meatballs were made by mixing of 250 g chicken meat with 125 g tapioca for each sample, seasoning (salt, pepper, garlic), and added ice with water/aloe vera gel  ratio (g/g) of 100/0; 85/15; 70/30; 55/45 and 40/60. The doughs were molded in ball-shape then boiled at 90 oC for 10 minutes. The meatballs were subjected to analysis of moisture content, the ability to scavenge of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical or radical scavenging activity (RSA), acid, peroxide and thyobarbituric acid (TBA) number,  physical properties including water holding capacity (WHC), cooking loss, and texture (softness, chewiness and deformation) as well as  acceptability by hedonic test. The results showed that the highest acceptability and antioxidative activity of meatballs was obtained in meatball with the ratio of water/gel between 55/45- 40/60 (g/g). This aforementioned meatball had softer texture and likely chewiness. The percentage of the WHC and cooking loss were not significantly different, but it had high RSA and lowest value of acid, peroxide and TBA numbers. ABSTRAKSaat ini konsumsi daging ayam ras pedaging meningkat hingga mencapai 3,7510 kg/kap/tahun. Hal ini disebabkan antara lain oleh meningkatnya jumlah penduduk dan usaha di sektor pangan yang menggunakan daging ayam ras. Disisi lain, daging ayam ras mengandung lemak cukup tinggi, sehingga mudah teroksidasi menghasilkan radikal bebas dan penurunan flavor. Daging ayam ras banyak digunakan sebagai bakso yang diolah melalui proses penggilingan daging dan perebusan, sehingga dapat memicu terjadinya oksidasi lemak. Oleh sebab itu, diperlukan antioksidan untuk menghambat oksidasi. Aloe vera diketahui mengandung senyawa flavonoid yang dapat menangkal radikal bebas. Tujuan penelitian ini adalah melakukan optimasi penambahan gel lidah buaya pada pembuatan bakso daging ayam ras untuk menghasilkan bakso dengan efek antioksidatif tinggi dan disukai. Pada penelitian ini gel lidah buaya ditambahkan untuk mensubtitusi es batu yang digunakan pada pembuatan bakso, mengingat kandungan air gel tinggi (> 98%). Pembuatan bakso untuk setiap 250 g daging ayam ditambah 125 g tapioka, bumbu (garam, merica, bubuk bawang putih) dan es batu yang dibuat dengan variasi rasio air/gel lidah buaya (g/g): 100/0; 85/15; 70/30; 55/45 dan 40/60. Bahan dicampur menjadi adonan dan dibuat bola-bakso, selanjutnya direbus pada suhu 90 oC selama 10 menit. Analisis yang dilakukan adalah kadar air, kemampuan menangkap radikal DPPH, angka asam, peroksida dan TBA (thyobarbituric acid); sifat fisik: water holding capacity (WHC), cooking loss, tekstur (kelunakan, kekenyalan dan deformasi) dan akseptabilitas bakso ditentukan secara inderawi dengan Hedonic Test. Hasil penelitian menunjukkan bahwa bakso dengan akseptabilitas dan aktivitas antioksidasi tinggi dibuat dengan es batu dengan rasio air/gel lidah buaya 55/45-40/60 (g/g).  Bakso tersebut lebih lunak dan kekenyalannya disukai. Persentase WHC dan cooking loss tidak berbeda nyata, nilai RSA tinggi, sedangkan angka asam, peroksida dan TBA paling rendah.

Abstract

Red palm oil (RPO) is a palm oil product that still retains carotene (pro vitamin A) in high contents. Diversification of RPO in food products should be developed to enhance consumers’ nutrition. This research was conducted to make margarine and baking shortening based on RPO and its application in baking products. The RPO used was neutralized crude palm oil (CPO) (RPO NPO) and from fresh fruit bunches (RPO FFB). Margarine was made into 2 types namely grade A (RPO 100%) and grade B (RPO: refined bleached deodorized palm oil (RBDPO) 50:50) and baking shortening also 2 types namely grade A (RPO: refined bleached deodorized palm stearin (RBDPS): refined bleached deodorized palm kernel oil (RBDPKO) 70:15:15) and grade B (RPO: RBBDPO (50:50): RBDPS : RBDPKO 70:15:15). Bakery products were made into 3 types of sweet bread, donuts and rolls cake. The margarine and baking shortening that obtained have high carotene, the peroxide value fulfills the standard of <10 mgeq/kg but high free fatty acid (FFA) about 0.1-0.3%, that is caused by RPO have high FFA. The sweet breads, donuts and rolls cake using RPO-based margarine and baking shortening have moisture content, fat content, FFA content, peroxide value and volume expansion (except donuts and rolls cake) similar to commercial products, but the carotene content was higher. Preference for color, aroma, texture and flavor of sweet breads, donuts and rolls cake using RPO : RBDPO (50:50) were quite high from RPO 100%, but lower compared to commercial products, relatively. Therefore, mixing of RPO and RBDPO can be an alternative in improving nutrition of bread products.

Abstract

This study aimed to measure the effect of roasting time on physicochemical properties and volatile compounds of unfermented cocoa liquor roasted with an oil bath method. Physicochemical properties (pH, temperature, and color), flavor, and volatile compounds were analyzed. The results showed that the longer the roasting time the higher the unfermented cocoa liquor’s temperature, °Hue, and ΔE value, but lower pH and L value. There were 126 volatile compounds obtained by various roasting time, identified as pyrazines (12), aldehydes (16), esters (1), alcohols (31), acids (15), hydrocarbons (11), ketones (19), and others (21). At 15, 20, and 25 minutes of roasting time, 69, 74, and 67 volatile compounds, respectively, were identified. Volatile compounds’ profiles were indicated to be strongly influenced by roasting time. The largest area and highest number of compounds, such as pyrazines and aldehydes, were obtained at 20 minutes, which was also the only time the esters were identified. As well as the time showed a very strong flavor described by panelists.

Abstract

Lai (Durio kutejensis) seed starches have a high retrogradation ability and low paste stability so that its function in food industry is less widespread. This phenomenon can be overcome by starches modification, such as acetylation using asetat anhidrat as modifying agent. This study aims to observe the physical properties of acetate starch such as swelling power and solubility, morphological characteristics, and amylographic properties (retrograde rate, viscosity, gelatinization temperature) and the results will be compared to native starch. Lai seed starches was acetylated using asetat anhidrat 3% and 4%, the reaction time variation was 15, 30, 45 and 60 minutes and the reaction pH used ranged from 8-8.5. Acetylation with a different amount of asetat anhidrat (3% and 4%) and different time of reaction (15, 30, 45, 60 min) give an optimum result of DS in 4% of asetat anhidrat with 15 minute of reaction time. DS that reached at those condition is 0.22 and has the same tipe as native starch (tipe A). The result of FTIR shown that there’s a new peak at 1735 cm-1 was a part of carbonyl group and the weakening of hydroxyl group peak of acetate starch. Acetylation decreased the final viscosity from 1472 cP to 1170 cP, setback value from 172 cM to 31cP, and breakdown from 798 cP to 350 cP. Meanwhile, the pasting temperature increased after acetylation from 71.82 °C to 76.05 °C. These result indicate that acetylation increased the resistance of retrogradation, and high pasting stability.
