Effect of three grinding methods on some properties of Nutmeg
LWT - Food Science and Technology, 1993Co-Authors: L. H. Mckee, L.d. Thompson, M. L. HardenAbstract:Abstract The particle size, composition and antioxidant capacity of Nutmeg ground by ambient, chilled and liquid nitrogen methods were studied. About 70% of Nutmeg ground by each of the three methods was classified as 'medium' particle size. Grinding method did not affect moisture content, which averaged 6.8%. Nutmeg ground by the ambient method had a higher percentage of steam volatile oil (5.8%) than Nutmeg ground by the chilled (5.5%) and liquid nitrogen (5.3%) methods. The percentage of oleoresin in Nutmeg ground under ambient conditions varied widely from batch to batch, while Nutmeg ground by the liquid nitrogen method had a more consistent batch-to-batch percentage of oleoresin. A series of standard solutions was prepared from pure Nutmeg oleoresin and a color equivalent was calculated for each sample to indicate the amount of color compound in the sample relative to the standard curve. The color equivalent of Nutmeg ground by the liquid nitrogen method (0.969 g/100 mL) was higher than that for Nutmeg ground by the chilled (0.748 g/100 mL) and ambient (0.902 g/100 mL) methods. The addition of 2.5% Nutmeg was found to have a slight antioxidant effect when tested in a model salad dressing formula.

Nutmeg : a review
Lebensmittel-Wissenschaft & Technologie, 1991Co-Authors: L. H. Mckee, M. L. HardenAbstract:Although whole Nutmeg is available, ground Nutmeg is the more popular form of the spice. Since the 7 to 16% oil content of Nutmeg makes grinding at ambient temperatures difficult, chill-conditioning and cryogenic grinding have been suggested as alternative methods of preparation. The chemical composition of Nutmeg, including moisture, mineral content, volatile oils, and oleoresins, are reviewed. Sensory properties and antioxidant ability of ground Nutmeg, Nutmeg oils, and other Nutmeg components are also discussed

Effect of Nutmeg Flesh (Myristica fragrans Houtt) against Streptococcus mutans growth
Journal of Syiah Kuala Dentistry Society, 2021Co-Authors: Putri Rahmi Noviyandri, Nurhadisah, Santi ChismirinaAbstract:Streptococcus mutans is an oral commensal. Its bacteria are involved in the dental caries pathogenesis. Nutmeg flesh (Myristica fragrans Houtt) is one of the native plants of Indonesia. Nutmeg flesh (Myristica fragrans Houtt) contains antibacterial properties such as alkaloids, flavonoids, tannins, terpenoids, saponins, and essential oil. The purpose of this study is to determine the effect of Nutmeg flesh (Myristica fragrans Houtt) extract in the inhibition of Streptococcus mutans growth. The extract of Nutmeg flesh (Myristica fragrans Houtt) was made using the maceration method with ethanol 96% as the solvent. The Diffusion methods to identify the inhibition of Streptococcus mutans growth. The concentration of Nutmeg flesh (Myristica fragrans Houtt) extract used in this study were 25%, 50%, 75%, and 100. The one-way ANOVA analysis showed that there was the effect of Nutmeg flesh (Myristica fragrans Houtt) extract on Streptococcus mutans growth with value p

The one-way ANOVA analysis showed that there was the effect of Nutmeg flesh (Myristica fragrans Houtt) extract on Streptococcus mutans growth with value p0.05, and then data was tested by Least Significant Difference (LSD). This study's conclusion showed an effect of Nutmeg flesh (Myristica fragrans Houtt) extract in inhibiting Streptococcus mutans growth. The concentration of Nutmeg flesh (Myristica fragrans Houtt) extract, which has the greatest inhibition zone on the growth of Streptococcus mutans, is at a concentration of 100% is 33,53 mm

Nutmeg: Open Source Software for M/EEG Source Reconstruction.
Frontiers in neuroscience, 2020Co-Authors: Leighton B. Hinkley, Corby L. Dale, Chang Cai, Johanna M. Zumer, Sarang S. Dalal, Anne M. Findlay, Kensuke Sekihara, Srikantan S. NagarajanAbstract:Neurodynamic Utility Toolbox for Magnetoencephalo- and Electroencephalography (Nutmeg) is an open-source MATLAB-based toolbox for the analysis and reconstruction of magnetoencephalography/electroencephalography data in source space. Nutmeg includes a variety of options for the user in data import, preprocessing, source reconstruction, and functional connectivity. A group analysis toolbox allows the user to run a variety of inferential statistics on their data in an easy-to-use GUI-driven format. Importantly, Nutmeg features an interactive five-dimensional data visualization platform. A key feature of Nutmeg is the availability of a large menu of interference cancelation and source reconstruction algorithms. Each Nutmeg operation acts as a stand-alone MATLAB function, allowing the package to be easily adaptable and scripted for the more advanced user for interoperability with other software toolboxes. Therefore, Nutmeg enables a wide range of users access to a complete "sensor-to- source-statistics" analysis pipeline.

Abuse of Nutmeg (Myristica fragrans Houtt.): studies on the metabolism and the toxicologic detection of its ingredients elemicin, myristicin, and safrole in rat and human urine using gas chromatography/mass spectrometry.
Therapeutic drug monitoring, 2006Co-Authors: Jochen Beyer, Dorothea Ehlers, Hans H. MaurerAbstract:Seeds of Nutmeg are used as spice, but they are also abused because of psychotropic effects described after ingestion of large doses. It was postulated that these effects could be attributable to metabolic formation of amphetamine derivatives from the main Nutmeg ingredients elemicin (EL), myristicin (MY), and safrole (SA). In a case of a suspected Nutmeg abuse, neither such amphetamine derivatives nor the main Nutmeg ingredients could be detected in urine. The metabolites of EL, MY, and SA were identified using gas chromatography-mass spectrometry in rat urine and their presence in human urine of the Nutmeg abuser was confirmed. The identified metabolites indicated that EL, MY, and SA were once and twice hydroxylated at the side chain. In addition, EL was O-demethylated at 2 positions followed by side chain hydroxylation. MY and SA were demethylenated and subsequently methylated. In the human urine sample, the following metabolites could be identified: O-demethyl elemicin, O-demethyl dihydroxy elemicin, demethylenyl myristicin, dihydroxy myristicin, and demethylenyl safrole. As in the human urine sample, neither amphetamine derivatives nor the main Nutmeg ingredients could be detected in the rat urine samples. Finally, toxicologic detection of Nutmeg abuse was possible by identification of the described metabolites of the EL, MY, and SA in urine applying the authors' systematic toxicologic analysis procedure using full-scan gas chromatography-mass spectrometry after acid hydrolysis, liquid-liquid extraction of analytes, and microwave-assisted acetylation of extracted analytes.
