Novel insight into physicochemical and flavor formation in naturally fermented tilapia sausage based on microbial metabolic network.

Food Res Int 2021 Mar 11;141:110122. Epub 2021 Jan 11.

Key Laboratory of Aquatic Product Processing, Ministry of Agriculture and Rural Affairs, National R&D Center for Aquatic Product Processing, South China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Guangzhou 510300, PR China; Co-Innovation Center of Jiangsu Marine Bio-industry Technology, Jiangsu Ocean University, Lianyungang 222005, PR China.

The quality and flavor formation in fermented fish sausages are based on the complex metabolism of microbial community. In this study, the dynamic changes of physicochemical characteristics, volatile compounds, and microbial communities in the naturally fermented tilapia sausage were studied during the fermentation process. The main physical indexes (gel strength, whiteness, and hardness), dominant flavor free amino acids (glycine, alanine, and glutamic acid) and characteristic volatile flavor compounds (hexanal, heptanal, octanal, benzaldehyde, (E)-2-octenal, 4-ethylbenzaldehyde, (E)-2-heptenal, (E,E)-2,4-decadienal, 1-octen-3-ol, 2-pentylfuran, and 2-ethyl-furan) were significantly enhanced after fermentation, and were positively correlated with Lactococcus, Pediococcus, Enterococcus, and Lactobacillus.

RIFM fragrance ingredient safety assessment, p-tolualdehyde, CAS Registry Number 104-87-0.

Food Chem Toxicol 2021 Jan 14:111982. Epub 2021 Jan 14.

Research Institute for Fragrance Materials, Inc, 50 Tice Boulevard, Woodcliff Lake, NJ, 07677, USA.

The existing information supports the use of this material as described in this safety assessment. p-Tolualdehyde was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, and environmental safety. Data from read-across analog benzaldehyde (CAS # 100-52-7) show that p-tolualdehyde is not expected to be genotoxic. Read More

Spatial variations in the occurrence of potentially genotoxic disinfection by-products in drinking water distribution systems in China.

Environ Pollut 2017 Dec 11;231(Pt 2):1463-1468. Epub 2017 Sep 11.

State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Science, Chinese Academy of Sciences, Beijing, China.

We investigated the occurrence of disinfection by-products (DBPs) with genotoxic potential in plant effluent and distribution water samples from four drinking water treatment plants in two Chinese cities using comprehensive two-dimensional gas chromatography-quadrupole mass spectrometry. We tested the samples for 37 DBPs with genotoxic potential, which we had previously identified and prioritized in water under controlled laboratory conditions. Thirty of these DBPs were found in the water samples at detection frequencies of between 10% and 100%, and at concentrations between 3. Read More

Functional characterization of a Niemann-Pick type C2 protein in the parasitoid wasp Microplitis mediator.

Insect Sci 2018 Oct 24;25(5):765-777. Epub 2017 Jul 24.

State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, China.

Niemann-Pick type C2 (NPC2) is a type of small soluble protein involved in lipid metabolism and triglyceride accumulation in vertebrates and arthropods. Recent studies have determined that NPC2 also participates in chemical communication of arthropods. In this work, two novel NPC2 proteins (MmedNPC2a and MmedNPC2b) in Microplitis mediator were identified. Read More

Volatile compounds of Viola odorata absolutes: identification of odorant active markers to distinguish plants originating from France and Egypt.

Chem Biodivers 2014 Jun;11(6):843-60

Institut de Chimie de Nice, Université Nice Sophia-Antipolis, UMR CNRS 7272, Parc Valrose, F-06108 Nice Cedex 2 (phone: +33-492076469; fax: +33-492076125); PAYAN BERTRAND, 28, Av. Jean XXIII, F-06130 Grasse; European Research Institute on Natural Ingredients (ERINI), Espace Jacques-Louis Lions, 4 Traverse Dupont, F-06130 Grasse.

Absolutes isolated from Viola odorata leaves, valuable materials for the flavor and fragrance industry, were studied. Violets are mainly cultivated in France and Egypt and extracted locally. The absolutes of the two origins showed different olfactory profiles both in top and heart notes, as evidenced by sensory analysis. Read More

Subacute toxicity assessment of water disinfection byproducts on zebrafish.

Pathol Oncol Res 2012 Jul 11;18(3):579-84. Epub 2011 Dec 11.

1st Department of Pathology and Experimental Cancer Research, Semmelweis University Budapest, Üllői út 26, 1085 Budapest, Hungary.

Disinfection of raw water is essential to the production of drinking water. However, by-products of disinfection may exert toxic effects. The potential toxic effects of two of these compounds, 4-ethylbenzaldehyde (EBA) and 2,4-difluoroaniline (DFA) were investigated using the zebrafish (Danio rerio) model. Read More

Comparison of two microalgal diets. 2. Influence on odorant composition and organoleptic qualities of raw oysters (Crassostrea gigas).

J Agric Food Chem 2003 Mar;51(7):2011-8

Laboratoire de Biochimie Alimentaire et Industrielle, Ecole Nationale des Ingénieurs des Techniques des Industries Agro-Alimentaire, Rue de la Géraudière, B.P. 82225, 44322 Nantes Cedex 3, France.

Oyster farming is of real economic interest in France. Oyster farmers attach more and more importance to improving the growth and the quality of their oysters. Some fatty acids known to be aroma precursors originate from microalgae such as Skeletonema costatum and Tahitian isochrysis clone. Read More
