Mustard white

When ground and mixed with water, the seeds of black mustard ferment and yield a sharp, irritating odor and a pungent taste white mustard does not react in this manner. 

Sinapine, CjgHjjOgN, was isolated as a thiocyanate from black mustard seeds (Brassica nigra) by Henry and Garot." Will and Laubenheimer first noted that sinapine occurs in white mustard seed in the form of the alkaloidal glucoside sinalbine, CajH jOuNgSg, which, on hydrolysis by the enzyme myrosin, also present in the seed, furnished dextrose, p-hydroxybenzylthiocarbimide and sinapine sulphate. Owing to its instability sinapine is unknown in the free state. The thiocyanate can be recrystallised from water and converted into the acid sulphate by treatment with sulphuric acid. 

Stubble turnips were found to be almost the equal of white mustard as a catch crop and source of nitrogen to subsequent crops (Kotnik Kopke, 2000).

A recent review of the metabolites of L. maculans and L biglobosa produced in diverse culture conditions [19] emphasized that both species biosynthesize host-selective and non-selective phytotoxins. Importantly, it was shown that the composition of metabolite profiles of L. maculans depended on the composition of the culture medium. In a chemically defined liquid medium, isolates virulent on canola produced mainly sirodesmin PL (1), a non-host-selective phytotoxin, minor sirodesmins with one, three, or four sulfurs bridging the dioxopiperazine ring (sirodesmin H (3) [20], sirodesmin J (4) and K (5) [21]) and phomalirazine (6) (Fig. 9.1). The various sirodesmins 1-5 and phomalirazine (6) caused necrotic lesions of different intensities on leaves of both resistant and susceptible plants. Phomalide (7), the first host-selective phytotoxin isolated from virulent isolates of L. maculans, caused disease symptoms (necrotic, chlorotic, and reddish lesions) on canola (susceptible to L maculans) but not on brown mustard or white mustard...

Teel Oil, or Oil of Sesamum.—The plant yielding this oil, the sesamum orientals, is extensively cultivated throughout India for the sake of the fine oil expressed from its seeds. The latter are imported from Calcutta under the name of teel seeds. They are about the size of white mustard seeds. Three varieties are known— namely, the white, the particolored, and the block. It is principally from the latter that the eesumum oil of commerce is obtained. The seed contains about forty-five per cent, of oil. This has been already mentioned as an adulterant of almond oil, and, according to Pereira, may be used as a substitute for the latter. 

Oil of Mustard.—This oil is precured by expression of the bruised seeds of tho black or white mustard. The mustard plant—rinapis—of which there are several species, appears to be indigenous to this country. It was formerly cultivated in Durham, but is now grown principally in the neighborhood of York. In India and the East, mustard is cultivated solely for the sake of the fixed oil it contains. The seeds of black musterd were first analysed by Tiiibieiioe, and have been since examined among others by Pelouze, Eobiquet, YOI. II. 

Pungent components produce a hot sensation on the tongue or at the back of the throat. The most important species of this group are capsicum, ginger, pepper (black and white), mustard and horseradish. 

Early research with irradiated paprika (Beczner et al, 1973), white pepper, nutmeg and ginger (Tjaberg etal., 1972) concluded that the technique was not suitable for the detection of these spices since the free radicals formed were short lived and could not be distinguished from intrinsic free radicals already present in the non-irradiated samples. More recently, a radiation-induced stable EPR signal has been observed for up to three months in paprika, white mustard and chilli (Stachowicz et al1992).

Putnam and Duke (115) screened for phytotoxicity in seed sources from 526 accessions of cucumber and found 3% of the accessions inhibited the indicator species, proso millet (Paniaum mctCaceum L.) and white mustard (BAa tZca. hittXa Moench), by more than 75%. In the field, some accessions reduced weed populations more than 50%, but less weed suppression occurred under periods of increased rainfall...
