As for the first time, the extracts of three sea cucumber species’ i.e, Actinopyga lecanora, Holothuria atra, and Stichopus vastus, were compared and tested on the cytotoxicity of cancer cells using MTT and Annexin V/Propidium Iodide assays. This study investigates the protection of sea cucumber extracts against the breast cancer cell line (T-47D). All three extracts were found to be actively declining the cancer cell progression, with the IC50 values of 6.25±0.50 µg/ml (A. lecanora), 7.5 ± 1.39 µg/ml (H. atra) and 3.25 ± 0.53 µg/ml (S. vastus). LC-MS/MS analysis was used to identify chemical compunds in the extracts. The 1,1-diphenyl-2-picrylhydrazyl (DPPH), total phenolic and flavonoid contents, and anti-collagenase activity were also assessed in all the three extracts. The results demonstrated the absence of antioxidant and flavonoid chemicals in S. vastus, A. leconara and H. atra extracts. However, H. atra contained phenolic compounds (0.4794 mgGAE/g DW). Furthermore, all tested extracts showed significant anti-collagenase activity, which supported the reduction of cancer cell proliferation. However, more research into the mechanism of action of the extract is needed before sea cucumbers therapeutic characteristics may be used to combat breast cancer.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90900253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 52 isolates of pigmented bacteria were isolated from seawater in the Krakal coastal area, Yogyakarta, Indonesia. Seven bacterial isolates showed high pigment stability. Profiling of pigment extracts using a mixture of acetone and methanol with UV–Vis spectrophotometric reading showed that the compounds produced were carotenoids. The highest total carotenoid content with UV–Vis spectrophotometric reading at 480 nm was produced by the Kral-3 isolate (1800 mg/g), followed by Kral-15 (1698.9 mg/g) and Kral-25 (797.2 mg/g) isolates. Analysis of the antibacterial activity of the carotenoid extracts of Kral-3, Kral-15, and Kral-25 isolates using the agar well diffusion method revealed a very strong inhibition score against Escherichia coli. In addition, the carotenoid extract of the Kral-3 isolate showed a strong inhibition score against Staphylococcus aureus, whereas the Kral-15 and Kral-25 isolates showed moderate inhibition scores. Based on the 16S rRNA gene analysis, the Kral-3, Kral-15, and Kral-25 isolates were identified as Kocuria rhizophilla, Calidifontibacter sp., and Rhodococcus ruber, respectively. Based on the findings, the novel bacterial strains are a potential bioresource for the commercial production of natural carotenoids.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88431383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to prioritize food and chemical pairs in the rejected fishery products. The rejection data from three major export destinations: the United States, the European Union, and Japan in 2017-2019 were used. Combinations of food and chemicals were developed and screened, followed by constructing a risk matrix to prioritize the pairs based on health and economic impact. Based on the health impact, a tuna–histamine pair was considered medium risk along with other commodities pairing with heavy metals. Tuna is the most exported seafood and suffers from the most loss; hence it has the highest score for severity and likelihood of economic impact. The combination of health and economic-based prioritization suggested that tuna–histamine was the top priority for immediate mitigation. The second priority consisted of shark–mercury, swordfish–mercury, octopus–cadmium; mahi-mahi–histamine was the third priority. This prioritization can assist risk managers in determining the order of commodities be acted upon based on health and economic considerations to enhance global market access.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86077436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The abundant fish bone waste from the fishery fillet industries in Indonesia,  can be employed as an alternative source of calcium to meet daily calcium needs. This research aimed to determine which of the six fish species (tilapia, catfish, grouper, snapper, tuna, kingfish mackerel) produces the best quality and the most cost-effective nano-calcium powder for a recommendation to the stakeholders. The calcium was extracted using an alkali treatment. The properties of the produced nano-calcium powders were analyzed for: proximate composition, calcium and phosphorus levels, color brightness level, XRD, FTIR, particle size, and SEM-EDX image analysis. The tilapia bone had the finest particle size of calcium (87.37 nm), while the grouper bone had the biggest particle size (281.4 nm). The brightness of all yields varied from 83.83 (beige-kingfish mackerel) to 90.64 (white-tilapia). The average calcium content from EDX analysis varied from 21.51% (snapper) to 34.37% (grouper). The average phosphorus levels ranged from 10.73% (kingfish mackerel) to 15.99% (grouper). The EDX Ca/P molar ratio was 1.41-1.66 across all samples. The FTIR spectra showed that all samples contained PO, CH, CO, NH, and OH groups. The XRD spectra pattern determined that the two main components of the fish bone nano-calcium powder were 90% hydroxyapatite and halite. All fish bone samples have the potential to be used as raw material for nano-sized calcium. However, grouper bone with the highest calcium content and the highest nano-calcium yield was the best choice for further study.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90302386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they belong to the crustacean group known to cause many allergies in Southeast Asian countries.

This study aims to analyze the effects of various heat processing on nutrient composition, soluble protein content, protein molecular weight profile, and allergenicity of white shrimp and mud crab. The processing was carried out by boiling, frying, and autoclaving. Changes in macronutrient content were determined using proximate analysis. Soluble protein content was analyzed using the Bradford method, while molecular weight and allergenicity profiles were analyzed using SDS-PAGE electrophoresis and ELISA techniques. Results showed that processing treatment could significantly reduce protein solubility. SDS-PAGE profile showed that heating shrimp and crab using autoclave at 121.1 oC and pressure of 0.2 MPa for 10 min was able to remove protein bands of 35-38 kDa, which were suspected as the allergen bands. However, boiling (100 oC for 10 min) and deep frying in palm oil (160 oC for 10 min) treatments of the samples gave stronger 35-38 kDa bands intensity than the unprocessed sample. Autoclaving was able to significantly reduce IgE reactivity to shrimp extract better than the boiling and frying process. In contrast, IgE reactivity of crab extract was increased by heat processing especially frying. Thus, autoclaving can be used in the white shrimp processing to produce hypoallergenic food.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89048017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to investigate the changes in quality, particularly umami-related component parameters and perform a comprehensive evaluation to assess scallop quality over time. In this study, the distinction in the abundance of microorganisms, K value, pH, color value, glycogen content, and ATP-related compound levels (i.e., ATP, ADP, AMP, IMP, HxR, Hx, and glutamic acid levels) were investigated to determine the quality of Ezo giant scallops. The parameters were evaluated every day for six days at 4°C post mortem of the scallops. The total viable aerobic count of marine bacteria increased from 1 to 3 log CFU/g over six days, and the K value increased sharply from 18% on day 2 to 66% on day 4. The pH decreased from 7.0 on day 0 to 6.0 on day 3, but the color value did not change during the six days of observation. The AMP content increased over three days and then decreased during the last three days of storage. IMP was not detected; meanwhile, the glycogen and glutamic acid levels were stable during the observation. Based on these results, the best recommendation is to serve the refrigerated scallops as sashimi for not more than two days and cook by the third day to preserve the quality.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73398984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
