Abstract

Choux pastry is a baked product that generally has low fiber content due to its primary ingredient, wheat flour, which contains minimal dietary fiber. Incorporating alternative ingredients rich in fiber can enhance its nutritional value. One such ingredient is Eucheuma cottonii seaweed flour, which is high in dietary fiber and offers potential for innovation in the utilization of fishery-based products. Dietary fiber plays an important role in binding water, improving digestion, and reducing the risk of certain diseases such as cancer. This research aimed to determine the optimal level of Eucheuma cottonii seaweed flour addition to choux pastry based on consumer preference. The study was conducted in December 2024 at the Fishery Product Technology Laboratory, Faculty of Fisheries and Marine Sciences, and at the Chemistry Application Laboratory and PPBS Service Building, Faculty of Mathematics and Natural Sciences, Padjadjaran University. An experimental method was used with four treatments: 0% (control), 7.5%, 10%, and 12.5% seaweed flour. Organoleptic tests (appearance, aroma, taste, and texture) were performed by 25 semi-trained panelists, and proximate analysis was conducted. The results showed that the choux pastry with 10% seaweed flour was the most preferred, with organoleptic scores of 7.8 for appearance, 7.6 for aroma, 7.5 for texture, and 7.7 for taste. Proximate analysis indicated that the 10% seaweed flour choux pastry contained 0.3% crude fiber, 2.9% moisture, 2.28% ash, 27.43% fat, 11.27% protein, and 56.09% carbohydrates.

Abstract

Pacific oysters (Crassostrea gigas) are one of the major aquaculture commodities that contribute greatly to the Japanese fishing industry. This study aims to describe the oyster farming management system based on field research experience in Hyogo Prefecture, Japan. The method used was participatory observation for eight months, covering all stages of aquaculture from seed collection to post-harvest. Observations showed that oyster farming is carried out using the hanging raft method (ikada-suika-shiki), relying on natural food in the form of plankton with depth management and regular hanger rotation. A seed training process (yokusei) was also applied to increase the oyster's resistance to environmental stress. The growth rate of oysters in the rearing phase ranges from 0.25-0.35 grams per day, and harvesting is done during winter to produce high-quality meat. The implementation of efficient and systematic production management has proven to increase yield and product quality. These results suggest that oyster farming practices in Japan can serve as a reference in the development of sustainable oyster farming in Indonesia.

Abstract

Drying has the potential to alter the physical, chemical, and organoleptic characteristics of food materials. This study aims to identify the composition of non-volatile flavor compounds in fresh and dried sea lettuce (Ulva lactuca). The identification of non-volatile flavor compounds was conducted using amino acid profiling through High-Performance Liquid Chromatography (HPLC). The organoleptic characteristics, including appearance, aroma, texture, and taste of fresh and dried sea lettuce samples, were assessed through a simple descriptive test. The quantitative amino acid analysis data and the descriptive test results were analyzed using a comparative descriptive method. The findings revealed that both fresh and dried Ulva lactuca contain 17 types of amino acids, comprising 9 essential amino acids and 8 non-essential amino acids, which influence flavor characteristics. The descriptive test indicated that fresh Ulva lactuca is characterized by clean, shiny, and soft light green to dark green sheets with an elastic texture and a distinctive fresh seaweed aroma. In contrast, dried Ulva lactuca exhibited a yellowish-green color, a stiff and brittle texture, and a stronger salty taste with a slight umami sensation. These findings highlight the potential of Ulva lactuca as a versatile ingredient in food product development, particularly for enhancing flavor and nutritional value.

Abstract

Mutu ikan laut segar merupakan indikator penting dalam menjamin keamanan dan kelayakan konsumsi. Penelitian ini bertujuan untuk menilai tingkat kesegaran ikan kakap (Lutjanidae) dan ikan ekor kuning (Caesio sp.) yang dijual di Pasar Kordon, Bandung Timur, menggunakan metode uji organoleptik berdasarkan SNI 2729:2021. Penilaian dilakukan terhadap enam parameter sensori utama oleh lima panelis, dengan rentang nilai 5 hingga 9. Hasil menunjukkan bahwa tingkat kesegaran kedua jenis ikan berada dalam kategori cukup segar, dengan nilai rata-rata berkisar antara 6,8 hingga 7,2. Ciri-ciri umum yang diamati menunjukkan bahwa ikan masih layak konsumsi, meskipun terdapat tanda-tanda awal penurunan mutu. Hal ini menunjukkan perlunya perbaikan dalam penanganan pascapanen dan penyimpanan agar mutu ikan tetap terjaga hingga ke tangan konsumen.
