Chromosome-scale assembly of apple mint (Mentha suaveolens).

Objectives: Mint oil is used in various commercial applications world-wide. Mint oil is typically harvested from commercial clones of peppermint or spearmints. Spearmints are the product of a cross between two diploid species: Mentha longifolia (horse mint) and Mentha suaveolens (apple mint).

Nondestructive and Rapid Screening of Aflatoxin-Contaminated Single Peanut Kernels Using Field-Portable Spectroscopy Instruments (FT-IR and Raman).

A nondestructive and rapid classification approach was developed for identifying aflatoxin-contaminated single peanut kernels using field-portable vibrational spectroscopy instruments (FT-IR and Raman). Single peanut kernels were either spiked with an aflatoxin solution (30 ppb-400 ppb) or hexane (control), and their spectra were collected via Raman and FT-IR. An uHPLC-MS/MS approach was used to verify the spiking accuracy via determining actual aflatoxin content on the surface of randomly selected peanut samples.

High-Throughput Flavor Analysis and Mapping of Flavor Alterations Induced by Different Genotypes of by Means of UHPLC-MS/MS.

The demand for mint is increasing from year to year, and it is more important than ever to secure a sustainable and robust supply of such an important plant. The USDA mint core collection provides the basis for many researches worldwide regarding, e.g.

Diploid mint (M. longifolia) can produce spearmint type oil with a high yield potential.

Mint oil is a key source of natural flavors with wide industrial applications. Two unbalanced polyploid cultivars named Native (Mentha Spicata L) and Scotch (M. × gracilis Sole) are the main producers of spearmint type oil, which is characterized by high levels of the monoterpenes (-)-carvone and (-)-limonene.

A high throughput toolbox for comprehensive flavor compound mapping in mint.

Essential oils of the genus Mentha are extensively used as flavor ingredients in the industry. To overcome the time consuming and laborious traditional flavor analysis, a new quick, high-throughput toolbox based on a bead-beater homogenization followed by a UHPLC-MS/MS analysis has been developed and validated. While terpenes could be directly detected using atmospheric pressure chemical ionization (APCI), carbonyl compounds and alcohols required derivatization by 3-nitrophenylhydrazine (3-NPH) and glycidyltrimethylammonium chloride (GTMA) to ensure sufficient sensitivity for analysis of a single leaf.

Trigeminal Receptor Study of High-Intensity Cooling Agents.

Compounds capable of providing trigeminal effects are important to the flavor industry. Cooling agents activate a class of transient receptor potential (TRP) channels. The objective of this study was to evaluate the effect of 18 cooling agents by high-throughput screening through TRPM-8 and TRPA-1 channels.
