Abstract: It is an object of the present invention to enhance the ?-amylase inhibitory activity of a fenugreek seed component. According to the present invention, the bitter taste of fenugreek seeds can be collaterally reduced. The present invention relates to a processed product of fenugreek seeds obtained by allowing ?-glucosidase to act on a fenugreek seed-derived material and the like, and the method for producing the same.

Abstract: Provided is a method for preventing decomposition/deterioration of a lipophilic component due to interaction with water, or due to interaction with light, enzymes, oxygen, or heat in the presence of water. The method for preventing decomposition/deterioration of the lipophilic component in the presence of water is characterized in that a complex comprising a lipophilic component, a phytosterol ester, and a cyclodextrin is formed, and the aforementioned lipophilic component is preserved in the form of said complex in the presence of water.

Abstract: It is an object of the present invention to obtain fenugreek seeds having reduced bitter taste without causing significant changes in non-bitter components contained in fenugreek seeds. The present invention relates to a method for producing fenugreek seeds having reduced bitter taste, comprising allowing ?-glucosidase to act on an eluate in which the components of fenugreek seeds have been eluted and then allowing the fenugreek seeds to absorb the eluate and ?-glucosidase, and a food containing such fenugreek seeds.

Abstract: The present invention provides DNA and RNA designed on the basis of the sequence of an enzyme gene for repressing the expression of the enzyme gene generating a lachrymatory factor from a precursor of the lachrymatory factor, and also a vector for introducing DNA for repressing the expression of the gene of the lachrymatory factor-producing enzyme into a vegetable.

Abstract: Provided is a method of quantifying a specific plant genus in a food or a food ingredient by a PCR method, comprising: (i) preparing a sample for correction where a sample derived from the specific plant genus to be detected and a standard plant sample are mixed in a predetermined ratio, and extracting genomic DNA from the sample for correction; (ii) preparing a test sample where a known amount of the standard plant sample is added to the food or the food ingredient to be examined, and extracting genomic DNA from the test sample; (iii) practicing a quantitative PCR method using the genomic DNAs and primers; and (iv) conducting correction with a standard value for correction determined for the sample for correction to calculate the amount of the specific plant ingredient contained in the test sample.

Abstract: The present invention relates to protein or polypeptide capable of converting 1-propenylsulfenic acid concerning the formation of lachrymatory factors generated when plants such as onions are broken into pieces or cut into lachrymatory factors, and also to DNA (lachrymatory factor-producing enzyme genes) encoding the protein or polypeptide; a primer usable for isolating a gene of a lachrymatory factor-producing enzyme of the genus allium and a method for isolating the gene with the primer; a recombinant vector containing the DNA; a transformant containing the recombinant vector containing the DNA; a method for preparing protein or a polypeptide having lachrymatory factor-producing enzymatic activity by culturing host cells transformed with the recombinant vector containing the DNA; protein or a polypeptide having the lachrymatory factor-producing enzymatic activity; and a nucleic acid molecule having a function of repressing the translation of mRNA on protein or polypeptide having the lachrymatory factor-prod

Abstract: The object of the present invention is to provide DNA and RNA designed on the basis of the sequence of an enzyme gene for repressing the expression of the enzyme gene generating a lachrymatory factor from a precursor of the lachrymatory factor, and also a vector required for introducing DNA for repressing the expression of the gene of the lachrymatory factor-producing enzyme into a vegetable.
