Amorphous silica is increasingly used in diagnostic and biomedical research because of its ease production relatively low cost. It generally regarded as safe has been approved for use a food or animal feed ingredient. Recent literature reveals that amorphous may present toxicity concerns at high doses. In anticipation potential human exposure to silica, it advisable examine cells different organs. Consequently, we investigated the response several normal fibroblast tumor varying doses...

Bioactive peptides (BPs) released by proteases from different food protein sources are often served as antioxidants in applications. This study aims to investigate 11 BPs derived fish and egg white potential natural antioxidant activity assays. The kinetic of the against xanthine oxidase (XOD) tyrosinase was also analyzed. antioxidative capacity indicated that VWWW (VW4, mackerel meat), followed IRW (IW3, white) VKAGFAWTANQQLS (VS14, tuna backbone protein), possessed highest...

To determine the histamine-relatedhygienic qualities and bacteria of scombroid fish fillets sold in traditionalretail markets, 61 samples were collected from northern southern Taiwan. It was found that content volatile base nitrogen most below 25 mg/100 g, which is regulatory level The ratio unacceptable samples/total for aerobic plate count Escherichia coli 100% 15% 20% samples, respectively, compared with requirements hygienic standards. average various biogenic amines all lower than 3...

ABSTRACT Sailfish fillets were involved in a 1994 food poisoning outbreak westem Taiwan. Samples collected from the victims’residues and retail wholesale suppliers. They analyzed for amines by gradient elution system of HPLC. Tryptamine, histamine, spermine, trimethylamine, spermidine, cadaverine found; other not detectable. The concentration histamine was higher than 100 mg/100g which assumed as toxic level. allergy‐like symptoms victims along with high content sailfish they had eaten...

The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating superoxide anion radical and reducing power, the immune-stimulating HB4C5 cells J774.1 cells. It found that increasing in correlating with concentration below 3.5 mg/ml. showed maximum relative activities cell proliferation (174%) IgM secretion (132%) at 120 µg/ml extract. Overheating slightly reduced At 80...

Slightly acidic electrolysed water (SlAEW) and (AEW) have been demonstrated to effectively inactivate food-borne pathogens. However, the underlying mechanism of inactivation remains unknown. Therefore, in this study, a differential proteomic platform was used investigate bactericidal SlAEW, AEW, sodium hypochlorite (NaOCl) solutions against Vibrio parahaemolyticus. The upregulated proteins after NaOCl treatments were identified as outer membrane K U. downregulated adenylate kinase,...
