332 results about "Cinnamic aldehyde" patented technology

Cinnamic aldehyde is the chemical compound that gives cinnamon its flavor and odor. Cinnamic aldehyde occurs naturally in the bark of cinnamon, camphor, and cassia trees.

Composite metal oxide loaded Pt-based nano metal catalyst and preparation method therefor

A Pt-based nanometer metal catalyst supported by a composite metal oxide and a preparation method thereof belong to the technical field of catalyst preparation. Composite Metal Oxide Supported Pt-Based Nanometal Catalysts Composite Metal Oxide as CeO 2 -ZrO 2 、TiO 2 -ZrO 2 , ZrO 2 -TiO 2 One of them, the specific surface area of ​​the catalyst is 250-400m 2 / g, the average particle diameter of Pt particles is 2-5 nm, and the mass percentage of Pt is 1.0-5.5%. The metal salt solution, chloroplatinic acid solution and potassium borohydride solution are mixed in a colloid mill to nucleate at a high speed, and then use kinetics to control the hydrothermal reaction, and further realize the compounding of metal oxides and the reduction of precious metals, and finally obtain a compound Metal oxide-supported Pt-based nanometal catalysts. The method is applied to the reaction of preparing cinnamyl alcohol by selective hydrogenation of cinnamaldehyde, and the conversion rate of cinnamaldehyde and the selectivity to cinnamyl alcohol can reach 90-100% and 90-100% respectively. The metal nanoparticles of the catalyst have high dispersion degree, small size, strong interaction with carrier and simple preparation method.

Spice composition for inhibiting food spoilage microorganisms

The invention discloses a spice composition for inhibiting food spoilage microorganisms, which consists of the following raw materials in percentage by weight: 30 to 50 percent of cinnamic aldehyde, 20 to 45 percent of eugenol, 20 to 40 percent of thymol, and 5 to 25 percent of salicylaldehyde. The eugenol, the cinnamic aldehyde, the thymol and the salicylaldehyde come from essential oil or natural-identical edible spices which are rich in the spices; components of the spice composition can be directly mixed, dissolved evenly and then used according to the proportion, or are dissolved and diluted by adopting solvents such as water, edible alcohol, propanediol, and grease to use, or are dispersed evenly by adopting other carriers such as dextrine and starch to use; the material selection of the spice composition is natural, safe and nontoxic; the co-synergistic action among spice ingredients ensures that the composition is highly-efficient and broad-spectrum to inhibit the food spoilage microorganisms; the spice composition has small usage amount, and can not apparently affect the flavor of food; and the spice composition is added into various food to effectively inhibit the growth and propagation of microorganisms which cause the food to spoil and deteriorate, thereby preventing spoilage of the food and keeping the food fresh.

Flavour compositions

A flavour composition comprises at least 0.5% by weight of one or more of the following group A materials: cinnamic aldehyde, basil oil, tarragon, cis-3-hexenyl acetate, cis-3hexenol, orange oil, lime, citral, and damascone; and at least 3% by weight of one or more of the following group B materials: anethole synthetic, alcohol C10, eucalyptol, methyl salicylate, clove bud oil, carvone laevo, benzyl benzoate, thymol, benzaldehyde, benzyl formate, ethyl salicylate, eucalyptus oil, ionone alpha, iso amyl acetate, rosemary oil, cardamom oil, ginger, eugenol, camomile oil, spearmint, and peppermint. These materials have been identified as being capable of inhibiting the growth of Porphyromonas gingivalis or the protease (arg-gingipain) activity of Porphyromonas gingivalis, and so to possess hitherto unappreciated antimicrobial properties. The invention thus enables compositions to be defined comprising flavour materials that enhance the antimicrobial efficacy of known antimicrobial agents against micro-organisms or metabolic processes associated with gum diseases. The invention also provides a consumer product, particularly an oral or dental care product, including such a flavour composition; a method for reducing or preventing gum disease; and use of the flavour compositions for reducing or preventing gum disease.

Fluorescent probe for monitoring lipid peroxidation processes in different subcellular organelles

The invention discloses a fluorescent probe for monitoring lipid peroxidation processes in different subcellular organelles, and belongs to the field of fine chemical engineering. The fluorescent probe is prepared through the steps of: enabling fluorine boron pyrrole derivatives to react with cinnamic aldehyde, wherein piperidine is used as a catalyst, and a 4 angstrom molecular sieve is used as a dehydrating agent; and performing quaternization on the obtained reactant so as to obtain molecules of the fluorescent probe. The probe contains active groups such as triphenylphosphine cations, morpholine and quaternary ammonium salt cations, the probe has a single-minded subcellular organelle targeting property because of the different active groups, and the probe can be optionally positioned on subcellular organelles such as mitochondria, lysosomes and cell membranes. The probe has zero toxin and zero side effects and is suitable for monitoring the lipid peroxidation processes in the subcellular organelles in different physiological processes through a fluorescent microscope or flow type cell analyzing technology. The probe is stable in solid condition nature and easy to store for a long time, an intuitional succinct detecting reagent with low cost is provided for inquiring processes relevant to the lipid peroxidation in cells, and microcosmic structural information is provided for detection by a subcellular organelle targeting property function.
