Abstract

Study on evaluation of fish freshness has been carried out using several parameters such as chemical, sensory, and physical parameter in which each has its own merits and demerits. Oxidation-reduction potential and K value are a physico-chemical and chemical methods available in assessing fish freshness which are both considered as objective methods. This study aimed to find out the effect of different temperatures storage on ORP and K value change of marine shellfish. Material used in the study were black tiger shrimp (Penaeus monodon) and scallop (Amusium sp.). The experiment was laboratory experimental method. The samples were stored in room temperature (35±1oC) and refrigerated temperature (11±1oC). Analyses performed were ORP value (pH/ORP meter) and K-value (Ion-exchange chromatography method) and analysis were conducted in 4 replication. This study was carried out at laboratory of Fisheries Processing Technology, UNDIP Semarang and laboratory of PAU, UGM Yogyakarta. The ORP of black tiger shrimp and scallop stored at refrigerated temperature initially were 0.23 Volts and 0.32 Volts. There were a maximum ORP of 0.3 Volts (shrimp) and 0.35 Volts (scallop) in the 2nd day of storage. These ORP then decreased to – 0.12 Volts and 0.01 Volts for shrimp and scallop, respectively. At room temperature storage,  the ORP ranging from 0.26 to 0.33 Volts. This value consecutively decreased to – 0.17 Volts (shrimp) and – 0.16 Volts (scallop) after 32 hours storage. Initial K value of black tiger shrimp and scallop stored at room temperature were 1.32% and 1.51%, respectively and after 32 hours storage there were an increase in K value to 6.14% and 5.43%. Increase in K value was slower for samples stored at refrigerated temperature than that of room temperature.

Abstract

Freshness of fish is crucial in determining the nutritional value and sale value of fishery products.Assessment of fish freshness can be done with various methods based on several principles of chemistry,physics, microbiology, and organoleptic. K value is one of freshness test based on ATP degradation.Analysis of K values can be done with Freshness Testing Paper (FTP III). This method is relativelypractical, easy, fast and the results can be accountable. The material that used in this study are fish milk fish(Chanos chanos Forsk) and short-bodied mackerel (Rastrelliger neglectus) with total 90 fish with anaverage weight of 99 grams / fish (milk fish) and 85 g / fish (short-bodied mackerel). The fish raw materialpurchased from Rejomulyo fish market (Semarang) and taken to the laboratory in a Styrofoam box that wasgiven ice on the inside. This research used an experimental method called descriptive exploration. Storageof samples was handled at different temperatures namely 30oC ± 2oC, 15oC ± 2oC and 1oC ± 0oC. Theobserved parameters include organoleptic test and analysis of K Value (FTP III). The results showed that Kvalues for all samples increased during storage at different temperatures. The highest K values of milk fishand short-bodied mackerel fish during storage at a temperature of 0°C was on 96-hours storage time. Thehighest K values of milk fish and short-bodied mackerel fish during storage at a temperature of 15 ° C wason 72-hours storage time. Whereas the highest K values in milk fish and short-bodied mackerel fish duringstorage at 30°C temperatures, was on the 24-hours storage time. The fastest increase in K value was observed at a temperature of 30°C compared to storage at a temperature of 15°C and 0°C for all the fish samples. This means that the deterioration quality of fish will be faster at high temperatures. K values of mackerel increased more rapidly than milk fish.

Abstract

Quality of surimi (minced meat of fish) usually decrease due to denaturation of protein. Addition of cryoprotective agent such as reducing sugar as anti denaturation of protein is very important during storage of frozen surimi. Recently, development of human lifestyle require healthy food such as utilization of stevia sugar (Stevia rebaudiana) which has low calorie that can be used to replace sorbitol and sucrose during processing of surimi. The purposes of this research are to observe the effect of different cryoprotective agents before and during storage as well as the effect of storage on quality of frozen surimi fish based on pH value, water holding capacity (WHC), gel strength and organoleptic value. Materials used was surimi made from kurisi (Nemipterus sp.), stevia sugar, sorbitol and sucrose. Research method used was experimental laboratory with research design of Completely Randomized Design with split plot in time. The main plot was difference of cryoprotectant (stevia sugar 0.6%; sorbitol 4%; sucrose 4%). The product was analysed every 15 days starting from 0 to 45 days storage at – 10oC. The results showed that different cryoprotectants agent gave no significant effect before storage treatment proceed. In addition during storage, the different of cryoprotectant gave significant effect to WHC and gel strength (SSS=1356,416; SS=1458,525; S=1511,307 g.cm) but not for pH. The organoleptic value for appearance on 15 days storage was SSS=7; SS=7; S=6,56 and Folding test showed SSS=7; SS=7.78; S=7,89)

Abstract

The use of chitosan as preservative agent in fish processing had been conducted for some reasons for example its usage as food additive that can prevent microbial growth, as antioxidative agent, and, to some extent to produce safe food. This research studied the application of chitosan on salted-dried anchovy (S. heterolobus) preservation during storage at room temperature. The aims of this research were to know the effect of treatment (chitosan concentration and storage time) on the quality of salted-dried anchovy (bacterial count and organoleptic test). The experimental design used was Split plot in time design and using Randomized Complete Block with two factors. The first factor was chitosan concentrations (0,0%; 0,5%; 1,0%) while the second factor storage time (0; 2; 4; 6; 8 weeks). The results indicated that chitosan concentration and storage time significantly reduced the total bacterial count (p<0,01) but not significantly different (p>0,05) for organoleptic test. The interaction of chitosan concentration and storage time significantly influenced the total bacterial count (p<0,01).

Agustini TW. 2020. Fish-based functional food to improve health quality during pandemic covid 19 era functional compounds of fish and algae: applications in food. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The current COVID-19 pandemic requires us to maintain our immune system, one of which is by consuming nutritious foods. The high number of free radicals in the body can reduce the immune system. Antioxidants can prevent the overproduction of free radicals so that they can prevent damage to immune cells. Functional food is food or food ingredients containing bioactive compounds that can provide benefits beyond basic nutrition and provide health effects in the prevention of a disease. Fish and algae are a source of bioactive compounds with various bioactivity. Fish and algae functional compounds that have been utilized include proteins, peptides, polyunsaturated fatty acids (PUFAs), polysaccharides, pigments, and various active compounds that have antioxidant, antiviral and anti-inflammatory properties. Antioxidant nutrients commonly used are protein hydrolysate, β-carotene, chlorophyll, astaxanthin, fucoxanthin and phycocyanin as well as polyphenol group compounds. These functional compounds can be applied in functional food products in health care and prevention of disease. This paper briefly explain the functional compounds of fish and algae, their application to functional food products and future development trends.

Abstract

Tujuan penelitian ini adalah mengembangkan IPTEK bagi masyarakat dengan memberikan informasi mengenai kualitas ikan asap yang diproses menggunakan smoking cabinet dan tungku tradisional. Penggunaan smoking cabinet dan tungku tradisional diharapkan dapat menjadi alternatif metode pengasapan yang ramah lingkungan, tidak menimbulkan bahaya karsinogen, serta menghasilkan kualitas ikan asap yang baik. Dalam penelitian ini, menggunakan jenis ikan lele  (Clarias batrachus) (L) dan patin (Pangasius pangasius) (P) karena banyak dijumpai di Indonesia dan sering diolah menjadi ikan asap. Sampel ikan diasapi menggunakan smoking cabinet (LSC dan PSC) dan tungku tradisional (LTr dan PTr), kemudian dilakukan analisa mengenai kualitas ikan asap meliputi organoleptik, analisa proksimat (kadar protein, lemak, air, dan abu), pH, kandungan Polycyclic Aromatic Hydrocarbons (PAHs) terutama Benzo (α) Pyrene (BαP), senyawa karbonil meliputi phenol, asam organik, dan formaldehid. Rancangan penelitian ini menggunakan pola faktorial 2x2x2, meliputi perbedaan metode pengasapan dan jenis ikan dengan dua kali ulangan. Hasil penelitian menunjukkan bahwa perbedaan metode pengasapan dan jenis ikan memberikan perbedaan sangat nyata (P<0,01) terhadap nilai proksimat (kadar protein, lemak, air, abu).   Kandungan phenol, formaldehid, dan asam organik yang lebih tinggi adalah menggunakan tungku. Sehingga dapat disimpulkan bahwa kedua metode pengasapan dan jenis ikan tersebut dapat diterapkan untuk pengolahan pengasapan ikan meskipun terdapat kecenderungan karakteristik yang spesifik pada produk yang dihasilkan dalam hal kenampakan, bau, tekstur dan rasa.
