Astaxanthin is used as a functional nutraceutical and pigment in many food products. It mostly exists the form of fatty acid ester nature. However, no detailed descriptions are available concerning stability oral absorbability astaxanthin esters. In present study, thermal esters from Haematococcus pluvialis were evaluated comparison with free-form astaxanthin.The was found to be higher than that astaxantin. After gavage esters, only detected digestive tract wall, blood plasma liver,...
Bacillus amyloliquefaciens NCPSJ7 showed potential fungicidal activities for the effective control of fungal infection. From PCR test, key genes (srfAA, sfp, fenD, bmyB, ituD, and ituC) were detected in B. NCPSJ7. These closely related to lipopeptides (LPs) synthesis. Next, three LPs families identified with liquid chromatography-mass spectrometry (LC/MS), including iturin A, fengycin surfactin. After purification C18, main active antifungal compound was proven be C14-iturin A by ESI-HRMS,...
The red color of processed shrimp, one the most attractive attributes and an important criterion for consumers, is often limited by thermal processing (microwaving, boiling frying), due to astaxanthin degradation. effect on in Pacific white shrimp (Litopenaeus vannamei) were investigated. A High-performance liquid chromatographic - atmospheric pressure chemical ionization mass spectrometry (LC-(APCI)-MS/MS) method was used identify quantify all-trans- cis-isomers astaxanthin, molecular...
Esterified astaxanthins are used as functional nutraceuticals and pigments in many food products. Unfortunately, the utilization is currently limited due to their chemical instability poor water-solubility. In this study, esterified were quantified purified from Haematococcus pluvialis using a novel precise approach. By HPLC-(+)APCI-MS/MS, twenty astaxanthin molecular species identified, of which classified into eight monoester forms (approximately 85%, w/w) twelve diester 15%, w/w),...
Abstract BACKGROUND We synthesized astaxanthin succinate diester (ASD), a novel (AST) derivate, with succinic anhydride and free AST. ASD was purified characterized using silica gel column chromatography spectrometry, respectively. RESULTS The final synthesis rate 82.63%. A stability test revealed high AST retention at pH 5.0–7.0. showed better than did under acidic conditions. Both sample ions lower rates Fe 2+ 3+ states. metabolic curve serum liver area the from 0 h to time t (AUC 0– )...
Bacillus amyloliquefaciens NCPSJ7 could secrete extracellular antimicrobial substances, showing potent antifungal activities. An active peptide AFP3 was isolated from the fermentation supernatant. After chromatography, purified tested for fungicidal activity, molecular mass, and stability. The results indicated that with a mass of around 3.3 kDa, showed discernible inhibition pathogen Fusarium oxysporum f. sp. niveum minimum concentration 31 µg/ml. It also exhibited excellent some...
The extraction of Antarctic krill oil enrich astaxanthins using n-hexane-ethanol solvent systems was studied, taking the total astaxanthin content, phospholipid content and yield as investigation indexes. Meanwhile, molecular species composition in which extracted under optimized conditions were characterized analyzed. Then digestion process bioaccessibility investigated by single-dose oral gavage with different doses oil, ICR mice model animals. Furthermore, bioacceptability from...
