Abstract ：
Objective: To study the chemical constituents of Gelidium amansii and lay a foundation for the research and development of functional food of Gelidium amansii. Methods: TLC and LC-MS were used to analyze the richness of chemical components in the ethanol extract of Gelidium amansii. The ethanol extract of Gelidium amansii was separated and purified by silica gel column and HPLC, and the structure of compounds were determined by GC-MS, NMR, and combined with the data reported in the literature. The antioxidant activity of some compounds was determined. Results: TLC and LC-MS analysis showed that the ethanol extract of Gelidium amansii was rich in secondary metabolites, and it was likely to be sterols. 29 compounds (5 sterols) were identified from the ethanol extract by CC-MS. Among them, palmitic acid (46.76%), ethyl palmitate (13.82%), cholesterol (7.20%), 4,6-cholestadien-3beta ol (4.99%) were the four compounds with the highest content. After chromatographic separation and NMR identification, 9 compounds were obtained, which were cholesterol (1), 1,2-diol phytoene (2), pagosterol C (3), 6-hydroxy- cholest-4-en-3-one (4), cholest-5-en-7-one (5), cholest-5-ene-3β, 7α diol (6), cholest-5-ene-3β, 7β diol (7), cholest -4-en-6-one (8), 3-hydroxyethyl-2-methyl-maleimide (9). Compound 7 has the strongest ability to scavenge DPPH and ABTS free radical with IC50 values of 0.18 mg/mL and 12.2 μg/mL, respectively. Conclusion: In this paper, the ethanol extract of Gelidium amansii were systematically studied for the first time. Compounds 3, 8 and 9 were new natural products. Some sterols showed good antioxidant activity. © 2024 Chinese Institute of Food Science and Technology. All rights reserved.

Abstract ：
On the basis of single factor experiment, the extraction process of Gelidium amansii ethanol extract (GAEE) was optimized by response surface methodology. Then, the GAEE was successively extracted by petroleum ether, ethyl acetate and n-butanol, and the antioxidant and antibacterial activities of different extraction phases were evaluated. The results showed that the optimum extraction conditions were as follows: extraction time was 64 min, ultrasonic power was 350 W, extraction temperature was 55 !, ethanol concentration was 60% and solid-liquid ratio was 1:35. The extraction rate of GAEE was 1.654 g/g, and DPPH radical scavenging rate of GAEE (2 mg/mL) was 58.29% Subsequent experiments proved that the antioxidant and antibacterial activities of different extraction phases were concentration dependent, and the antioxidant and antibacterial activities of ethyl acetate phase were the strongest. IC50 values of ethyl acetate phase against DPPH, ALTS free radicals, and hydroxyl radical were 672.4, 14.1, 599.7 μg/mL respectively. Their minimum in hibitory concentrations (DIC) of ethyl acetate phase against Staphylococcus aureus and Vibrio parahaemolyticus were 156.3, 156.3 μg/mL, and the minimum bactericidal concentrations (DLC) of ethyl acetate phase against Staphylococcus aureus and Vibrio parahaemolyticus were 625, 312.5 μg/mL. © 2023 Chinese Institute of Food Science and Technology.

Abstract ：
The purpose of this study was to explore the potential of the development and application of Paecilomyces hepiali, a fungus with edible and medicinal value, as a foodborne antioxidant and anti-aging agent. Its n-butanol extract (PHE) from rice cultures was selected for anti-aging experiment because of significant free radical scavenging activity in vitro. In vivo, PHE could significantly prolong the mean lifespan, 50％ survival days, and the maximum lifespan of Drosophila on a high-fat diet. It is amazing that the mean lifespan increased from 19.1 days to 32.9 days, 50％ survival days increased from 15.7 days to 34.3 days, and the maximum lifespan extended from 44.7 days to 52.7 days, when the high-fat female Drosophila model was fed with 10 μg/mL PHE. Further research showed that PHE reduced the accumulation of peroxide products and increased the activity of antioxidant enzymes. Then, through antioxidant activity tracking, dimerumic acid (compound 1, the IC50 value of 3.4 μg/mL on DPPH free radicals scavenging activity), 4,5-dihydroxy-3-methoxypentanoic acid (compound 2, new compound), and thymidine (compound 3) were isolated from PHE. It is worth mentioning that dimerumic acid, the major antioxidant compound of PHE (content up to 3％), was discovered in P. hepiali for the first time. It was concluded that PHE showed excellent anti-aging activity at a very low concentration on fat diet-induced high fat Drosophila melanogaster, and dimerumic acid may be its main material basis. These results indicated that PHE had the potential to be developed as antioxidant and anti-aging agent in the healthcare industry.

Abstract ：
For food preservation, the packaging film needs to have higher antibacterial activity in initial phase and keep longer activity. In this study, cinnamaldehyde (CA) and its sulfobutyl ether-beta-cyclodextrin inclusion complex (CA/S) were used to fabricate fish gelatin antibacterial composite films. The addition enhanced the elongation at break and light barrier property of the films. Film forming solution incorporated with CA and CA/S presented the most excellent inhibition ratio against Pseudomonas aeruginosa, which was 98.43 +/- 1.11% in initial period and still 82.97 +/- 4.55% at 72 h. Further, the packaging solution of gelatin combined CA and CA/S effectively inhibited the growth of microorganisms during preservation of grass carp slices. Especially, the total volatile salt-based nitrogen (TVB-N) did not exceed 10 mg/100 g at the end of storage, indicating that the active coating could obviously extend the shelf life of fish muscle. This work provided a promising food packaging system with antimicrobial and environmentally friendly.
