AI Technical Summary

Benefits of technology

[0016] The invention is directed, in part, to the discovery of a naturally-occurring source of 2-furfurylthiol ("FFT"), namely seeds of the Brassica genus. The invention also includes the discovery that, when heated, seeds within the Brassica genus produce a relatively-high concentration of FFT, thereby providing not only a natural FFT source, but also an economical and efficient FFT source.

Problems solved by technology

However, in many situations, this no longer is an acceptable option.
In particular, consumers are increasingly demanding "all natural" consumable products.
Unfortunately, however, when these materials are heated, they produce relatively low concentrations of FFT.
Therefore, they are rather inefficient and uneconomical as sources of natural FFT.

Embodiment Construction

[0028] These examples are provided to help illustrate various aspects of the invention. However, the examples do not limit the scope of the invention.

[0029] All of the seeds used in these working examples were obtained from Forbes Frozen Foods of Cincinnati, Ohio.

[0030] 1. Concentration of FFT in Heated Brassica Seed

[0031] Approximately ten grams each of various types of Brassica seed were heated as described in Table 1 below. The concentration of FFT subsequently was determined by using a stable isotope dilution assay, although other procedures may be used, as known to those of ordinary skill.

[0032] The heated Brassica seed was weighed and extracted with dichloromethane (50 ml) containing deuterated FFT ([.sup.2H.sub.2]-furfur-ylthiol, at a concentration of 20 .mu.g per 50 mg). The volatile compounds subsequently were isolated by applying the high vacuum transfer technique described by Jung et al. (Lebensm.-Wiss. U Technol. 225:55-60, 1992), the Jung et al. article being incorporat...

Abstract

A process for producing 2-furfurylthiol ("FFT") in Brassica seed includes heating Brassica seed under a temperature and for a time sufficient to produce an elevated amount of FFT in the Brassica seed. The heated seed may be extracted and / or otherwise treated, and may be used to provide a flavorant or odorant to consumables such as foods.

Description

[0001] This invention relates to the production and use of 2-furfurylthiol ("FFT"), and more particularly, to the production of FFT from natural sources.DESCRIPTION OF THE RELATED ART[0002] 2-furfurylthiol ("FFT") is a highly-desirable flavorant and odorant compound. Not only does FFT provide desirable aroma and taste characteristics, but also it is effective at extremely low concentrations. In particular, the odor threshold for FFT is 0.01 .mu.g / L of water. Accordingly, FFT may be used in small amounts, thereby making its use highly cost-effective.[0003] In the past, the demand for FFT has been met by making FFT synthetically. However, in many situations, this no longer is an acceptable option. In particular, consumers are increasingly demanding "all natural" consumable products. In many instances, in order for a consumable product to be labeled "all natural", the product may not include any synthetically-made compounds. Accordingly, there is a growing demand for FFT which is deriv...
