In this research, the occurrence of hygienic quality and histamine in commercial brined and dried milkfish products, and the effects of brine concentrations on the quality of brined and dried milkfish, were studied. Brined and dried milkfish products ( = 20) collected from four retail stores in Taiwan were tested to investigate their histamine-related quality. Among them, five tested samples (25%, 5/20) had histamine contents of more than 5 mg/100 g, the United States Food and Drug Administration guidelines for scombroid fish, while two (10%, 2/20) contained 69 and 301 mg/100 g of histamine, exceeding the 50 mg/100 g potential hazard level. In addition, the effects of brine concentrations (0%, 3%, 6%, 9%, and 15%) on the chemical and bacteriological quality of brined and dried milkfish during sun-drying were evaluated. The results showed that the aerobic plate count (APC), coliform, water activity, total volatile basic nitrogen (TVBN), and histamine content values of the brined and dried milkfish samples decreased with increased brine concentrations, whereas those of salt content and thiobarbituric acid (TBA) increased with increasing brine concentrations. The milkfish samples prepared with 6% NaCl brine had better quality with respect to lower APC, TVBN, TBA, and histamine levels.

Article Synopsis
  • The Indian Coffee Plum (Flacourtia jangomas) is a medicinal plant known for its bioactive compounds and potential therapeutic benefits, prompting research into its extracts from bark for medical applications.
  • The study involved extracting phytochemicals using methanol, conducting screenings, and comparing the biological activities of the extracts, revealing the presence of new compounds like methyl caffeate and flacourtin.
  • Results showed the extract has strong antioxidant and cytotoxic properties, pain relief effects, and moderate thrombolytic action, but limited antibacterial and antifungal activities, indicating a need for further research on its bioactive compounds.

This research aims to isolate, characterize, and analyze pure compounds from leaf extract to investigate its antibacterial, antidiabetic, cytotoxic, and phytotoxic effects. Fresh leaves were collected, dried, and subjected to methanol extraction to obtain a crude extract. From the petroleum ether fraction (PEF) of this extract, three fractions-designated LM1, LM2, and LM3-were prepared using column chromatography.

The use of hydrogel-based interfacial solar evaporators for desalination is a green, sustainable, and extremely concerned freshwater acquisition strategy. However, developing evaporators that are easy to manufacture, cheap, and have excellent porous structures still remains a considerable challenge. This work proposes a novel strategy for preparing a self-assembling sponge-like poly(vinyl alcohol)/graphite composite hydrogel based on the Hofmeister effect for the first time.

Background: Cyclodextrins selectively bind with reactants and facilitate chemical reactions through supramolecular catalysis, similar to the mechanisms employed by enzymes. In this paper, β-cyclodextrin was used as a supramolecular catalyst in water as a green, reusable, and ecofriendly solvent system to synthesize spiro-benzimidazoquinazolinones and spiro-benzothiazoloquinazolinones.

Objective: A supramolecular catalyst β-cyclodextrin (β-CD) is used to synthesize spiro- benzimidazoquinazolinones and spiro-benzothiazoloquinazolinones multicomponent reaction involving the condensation of dimedone, isatin, and 2-aminobenzimidazole/2-aminobenzothiazole.
