Abstract

This research aims to determine the effect of oats addition in wheat cookies formulation seen from physical and sensory characteristics. Six formulations used in this research consist of wheat flour and oats mixture namely Control (100%:0%), Formulation 1 (80%:20%), Formulation 2 (60%:40%), Formulation 3 (40%:60%), Formulation 4 (20%:80%), and Formulation 5 (0%:100%). Based on analysis of variance result at α = 5%, there was a significant difference in the value of hardness and work from control and all variation of cookies’ formulation. It was also found that the decreasing composition of wheat flour and increasing composition of oats caused a decrease in the value of hardness and work. The addition of oats in the formulation of wheat cookies increases the level of brightness (L), decreases the value of a* (red tone), and increases the value of b* (yellow tone) of cookies. From sensory evaluation, compared to controls, the addition of oats in the formulation increased the acceptance rating for color parameter for all formulation, taste parameter for Formulation 2 until 5, and overall parameter for Formulation 2 and 3, while for the texture parameter, the addition of oats did not provide an increased in the acceptance rating.

Abstract

Edible flower adalah jenis bunga yang aman untuk dikonsumsi. Edible flower kaya akan senyawa bioaktif seperti asam fenolik, karotenoid, dan flavonoid. Penelitian ini bertujuan untuk mengeksplorasi dua jenis edible flower, yaitu Nasturtium (Tropaeolum majus) dan Torenia (Torenia fournieri) guna pengembangannya sebagai produk teh celup. Teh celup bunga Rosella yang sudah dikenal luas digunakan sebagai produk pembanding. Pengolahan teh celup terdiri dari beberapa tahapan yaitu persiapan dan pengeringan edible flower dan proses penyeduhannya. Seduhan teh edible flower kemudian dianalisis total flavonoid, aktivitas antioksidan, dan sifat sensorisnya. Hasil penelitian menunjukkan bahwa seduhan teh celup bunga Torenia  mempunyai total fenol dan aktivitas antioksidan paling tinggi, yaitu 58,04 mg QE/g ekstrak dan IC50 9,18 mg/L, disusul oleh seduhan teh celup bunga Nasturtium (45,12 mg WE/g ekstrak dan 11,62 mg/L) dan teh celup bunga Rosella (19,55 mg QE/g ekstrak dan 19,77 mg/L). Seduhan teh bunga Torenia mendapatkan respons sensoris hedonik yang setara dengan seduhan teh bunga Rosella untuk atribut warna, aroma dan rasa, yaitu disukai, tetapi lebih baik untuk atribut keseluruhan (disukai dibanding agak disukai). Sedangkan teh bunga Nasturtium mendapatkan respons sensoris hedonik lebih rendah dari keduanya. Diantara dua teh edible flower yang diuji, teh bunga Torenia lebih berpotensi untuk dikembangkan menjadi teh herbal karena mempunyai respons sensoris setara dengan teh bunga Rosella tetapi mempunyai aktivitas antioksidan yang lebih tinggi.

Abstract

Chocolate is cacao nib processed product which is favorite commodity in the world, nevertheless, many of consumer have not known about the process. Notable stage in cacao processing is roaster process. Cacao roasting process currently uses conventional methods, which have weaknesses like energy wastage and bioactive compounds damage. Vacuum drying oven is new roasting method which uses low pressure and temperature. Through this research, the difference of aroma development between roasting process on conventional and vacuum drying oven method was investigated. Roasted cacao was extracted by water distillation, then distillate was separated by diethyl ether partition. The extract was characterized with GC-MS. The Characterization result shown that temperature 70°C contained 11 volatile compounds and temperature 80°C, 90°C and 140°C contained 7 volatile compounds. The higher roasting temperature, the more diverse of volatile compound. The best result in cacao roasting was on vacuum drying oven at 90°C, which has similar aroma with 140°C as control sample.

Abstract

Red betel leaf (Piper crocatum) is a plant growing in tropical areas and previously known as an ornamental plant, but then later used as medicinal plant. Previous researches found that red betel leaves contain bioactive compounds such as alkaloids, flavonoids, tannins, and many more that have potential to be used as antioxidant. The extractions were carried out using variations of solvent types (ethanol, water, and ethyl acetate) and feed to solvent (F:S) ratios in g/ml (F:S=1:20, F:S=1:25, F:S=1:30). The best conditions from this research were the usage of ethanol as the solvent. In addition to its ability to extract the compounds potential as antioxidant and F:S ratio of 1:30, it could give highest yield of extract. Variation of solvent type and variation of F:S have significant effect on the value of antioxidant activity (IC50) of the red betel leaf sample.

Abstract

Curcuma aeruginosa is one of the herbs with health benefits and has been used in traditional medicine, has the characteristic bitter taste, so that limited use was. The formation of walls in the active component coating process can minimize direct contact of bitter receptor cells in the oral peripherals so the perception of bitterness can be reduced. This study used a variation of the WPI concentration as the coating wall materials 10%, 15% and 20%. Formation of coating walls was analyzed using SEM later in the sensory test for effectiveness decreased level of bitterness. The addition of 10% WPI results in the best wall formation was in Curcuma aeruginosa, which could decrease perception of significant bitterness. In contrast to the addition of WPI 15% and 20% were found in an oval shape, craters and ruptures form on coating wall, reducing the protection of the core component and contact with bitter receptor cells in the oral peripheral resulting in bitters taste perception increasing.

Abstract

Misuse of chemicals, such as borax, as an additive in food is still common. This abuse is intended to increase elasticity and crispiness for longer in food products, even though borax is prohibited in the food industry. Some food products on the market that often contain borax are tofu, meatballs, noodles, and crackers. Research studies and mass media in several traditional markets in Indonesia have proven and verified the presence of borax in crackers. Based on this, we want to know whether there is the same thing in the distribution of crackers at Blauran Market, Salatiga City. Therefore, this research aims to quantitatively determine the status of borax in crackers sold at Blauran Market, Salatiga City, in 2023—a quantitative descriptive research method. Sampling used the purposive sampling method. The research design used was a completely randomised factorial design. The first factor is the type of cracker, consisting of four levels: gendar cracker brand X, gendar cracker brand Y, white eggplant cracker brand minute. Each treatment combination was repeated three times to obtain 24 experimental units. Quantitative test of samples using a UV-VIS spectrophotometer. Data processing using two-factor ANOVA with replication. The test results showed that the four brands of cracker samples contained >100 ppm borax. The highest borax content was in white eggplant crackers.

Abstract

Kopi manggarai menjadi salah satu kopi dengan kualitas unggul di Indonesia, tidak hanya dari cita rasa namun dari keunggulan dari senyawa bioaktif. Senyawa bioktif kopi memberikan manfaat lain terutama dapat menjadi senyawa fungsional yang bermanfaat bagi kesehatan. Teknik perendaman biji kopi akan mempengaruhi munculnya senyawa bioaktif. Perendaman biji kopi akan menyebabkan terjadinya proses fermentasi, yang akan menyebabkan terjadinya reaksi sintesis metabolit mikroorganisme yang dapat menghasilkan senyawa bioaktif yang memiliki nilai fungsional. Dalam penelitian ini dilakukan identifikasi senyawa bioaktif kopi manggarai arabika dengan perbandingan proses lama perendaman yaitu secara full wash dan semi wash. Hasil identifikasi yang diperoleh variasi  senyawa bioaktif pada setiap perlakuan memberikan dampak yang berbeda, semakin lama proses perendaman akan memberikan kuantitas senyawa bioaktif yang semakin banyak. Sedangkan semakin pendek waktu perendaman akan memberikan variasi senyawa bioaktif yang semakin tinggi. Namun adanya proses roasting akan mempengaruhi kualitas senyawa bioaktif pada kopi manggarai arabika
