Abstract

Optimization of anthocyanin pigment extraction from butterfly pea flowers (Clitoria ternatea L.) is an important focus to increase the efficiency of obtaining valuable active compounds. This study marks an initial approach in the application of Microwave-Assisted Extraction (MAE) using 0.75% aquadest-tartaric acid solvent, with the hope of producing more stable anthocyanins. The main objectives of this study were to identify the effect of the solvent-material ratio, extraction duration, and MAE power level on anthocyanin levels (mg/L) through the One-Factor-At-a-Time (OFAT) method. The results showed that the optimal treatment was obtained at condition P17, with a solvent-material ratio of 1:15, an extraction time of 15 minutes, and an MAE power of 450 watts, which produced an anthocyanin level of 33.89 ± 0.47 mg/L. These findings confirm that increasing the solvent-material ratio to the optimal point contributes to increasing anthocyanin recovery. However, excessive MAE time and power can cause pigment degradation. The optimal ratio variables were found to be in the range of 1:15 to 1:25, extraction time 9–15 minutes, and MAE power 270–450 watts. This study is expected to be the basis for further optimization using the Response Surface Methodology (RSM) method which allows for deeper analysis of the interactions between variables.

Abstract

Abstract Surabaya is one of the places for producers who provide MP-ASI products with various attributes, one of these products is MP-ASI premixed rice. This study aims to find out some of the attributes with the highest importance value for consumers in choosing MP-ASI premix rice products and identify consumer preferences on the sub-attributes of MP-ASI premix rice products. The attributes used in this study were cooking time, the type of material, the type of packaging, the addition of nutrients, the flavor variant, and the place of purchase. The research was carried out using a survey method. The total number of respondents was 100 that determined using the Slovin formula, and the collection of respondents was carried out using a two-stage cluster sampling technique. The premixed rice MP-ASI products that are the preference according to consumers are made from white rice (0,24) with the addition of fat nutrients (0,41), have a type of plastic bottle packaging (0,06) with a cooking time of less than 20 minutes (0,34), and have a variant of fish meat flavor (0,16) which is sold online (0,14). The results of the consumer preference analysis from this study can be used as a consideration in developing premix rice MP-ASI products.   Abstrak Surabaya adalah salah satu tempat bagi produsen yang menyediakan produk MP-ASI dengan berbagai atribut, salah satu produk tersebut adalah beras premiks MP-ASI. Tujuan dari penelitian ini adalah untuk menentukan beberapa atribut dengan nilai kepentingan tertinggi bagi konsumen dalam memilih produk beras premiks MP-ASI serta mengidentifikasi preferensi konsumen pada sub-atribut produk beras premiks MP-ASI. Penelitian dilaksanakan menggunakan metode survei, total jumlah responden adalah 100 ditentukan menggunakan rumus Slovin, dan pengambilan responden dilakukan dengan teknik two-stage cluster sampling. Produk MP-ASI beras premiks yang menjadi preferensi menurut konsumen yaitu berbahan dasar beras putih (0,24) dengan penambahan nutrisi lemak (0,41), memiliki jenis kemasan botol plastik (0,06) dengan waktu tanak kurang dari 20 menit (0,34), dan memiliki varian rasa daging ikan (0,16) yang dijual secara online (0,14). Hasil analisis preferensi konsumen dari penelitian ini dapat dijadikan pertimbangan dalam mengembangkan produk MP-ASI beras premiks.

Abstract

Pedada (Sonneratia caseolaris) has great potential as a source of natural antioxidants. The high antioxidant content in pedada fruit requires an appropriate extraction method so that the extracted antioxidant levels in pedada fruit can be maximally extracted. However, the extraction of active compounds from pedada fruit is often limited by the dense cell structure. Pedada fruit extraction can be done using a modified maceration method with Pulsed Electric Field (PEF) pretreatment, so as to shorten the extraction time and require less solvent in the process. It is expected that PEF can damage the cell structure and increase the solubility of antioxidant compounds in the solvent. The quality of the resulting extracts will be evaluated based on total phenol content, total flavonoids, free radical scavenging activity, and antioxidant compound profile. The best treatment was obtained based on antioxidant analysis of the extraction results, namely at a PEF time of 2 minutes with IC50 DPPH values of 18 ppm, IC50 FRAP 37 ppm, total phenol content of 434 mgGAE/L, and total flavonoid content of 120 mgQE/L.
