摘要:
According to the present invention, a low common salt soy sauce having a favorable flavor, and, in particular, a low common salt soy sauce having a favorable flavor, containing ethanol, 2-phenyl ethanol, isobutyl alcohol, and isoamyl alcohol, which are known as important aromatic components in soy sauce at high concentrations, and further containing succinic acid, which is a taste component, at a high concentration can be obtained without using special means. Conventional soy sauce powders are disadvantageous in that they are likely to become hygroscopic and deliquescent and thus they easily form powder blocks during storage, and that they have high stickiness and thus they are less likely to be uniformly mixed with other powder components. The present invention provides a soy sauce powder having a favorable flavor and containing 2-phenyl ethanol and succinic acid at high concentrations in order to overcome such disadbantages without using special means. The low common salt soy sauce of the present invention is obtained by a method for producing a low common salt soy sauce, which comprises adding a carbohydrate raw material to moromi in which the viable soy sauce yeast cell count per 1 g of moromi is 1 x 10 7 cells or more, adjusting the common salt concentration of the moromi in a manner such that the common salt concentration in moromi juice after maturation is 4.0 to 12.0 w/v%, and carrying out fermentation and maturation of the moromi. The pH of the obtained low common salt soy sauce is 4.7 to 6.0.

Provided is an amadoriase having heat resistance superior to that of conventionally known amadoriase. Provided is an amadoriase having substitution or deletion of one or more amino acid residues at positions corresponding to amino acids selected from the group consisting of three amino acid residues from the carboxyl terminal and amino acids at positions 151, 43, 53, 267, 350, 185, 196, 299 and 323 in the amino acid sequence of Amadoriase derived from Coniochaeta species indicated in SEQ ID NO: 1. Enzyme and glycated hemoglobin assay kits can also be provided that have superior storage stability even in the case of being subjected to increasingly severe temperature conditions such as during distribution at ambient temperatures, long-distance transport or in the production of oxygen sensors.

Provided are a seasoning that contains deep and rich flavor of ingredients mainly composed of a large amount of glutamic acid, and a method for producing the seasoning. The glutamic acid content in a glutamic acid containing seasoning liquid thus produced is not lowered even after long-term storage thereof. Herein, a protein raw material such as wheat gluten, defatted soybeans, and an extracted residue of dried and fermented fish shavings is enzymatically decomposed by the liquid koji. In that step, a zinc containing compound or zinc yeast is added to the mixture of the raw materials such that the zinc concentration is set in the range from 5 ppm or more to 700 ppm or less as a conversion amount of pure zinc. This procedure facilitates the enzymatic decomposition to produce an excellently flavored seasoning liquid or powder including a large amount of glutamic acid.
摘要:
There are provided, firefly luciferase with excellent thermostability and/or storage stability and a process for its production. Firefly luciferase having the amino acid sequence of firefly luciferase, wherein the amino acid corresponding to position 287 of Heike firefly luciferase has been replaced with alanine, or wherein the amino acid corresponding to position 392 has been replaced with isoleucine, and a gene for the firefly luciferase. By utilizing this gene, it is possible to efficiently produce firefly luciferase with increased stability. It is also possible to obtain firefly luciferase with further increased stability by combination with a mutation in which the amino acid at position 326 has been replaced with serine, and/or a mutation in which the amino acid at position 467 has been replaced with isoleucine.

Disclosed are: a firefly luciferase for use in the inexpensive, highly accurate and highly sensitive nucleic acid analysis using dATP but any expensive reagent having poor reactivity to DNA polymerase such as dATPαS; and a nucleic acid analysis method using the firefly luciferase; and a nucleic acid analysis kit. Specifically disclosed are: a composition for use in the analysis of a nucleic acid, which comprises a luciferase whose reactivity to dATP is 1/400 or less relative to its reactivity to ATP; a method for the analysis of a nucleic acid, which is characterized by using the composition; and a kit for the analysis of a nucleic acid, which comprises the composition.
摘要:
It is intended to provide a means for obtaining a novel soy sauce with less soy sauce flavor and having a rich flavor although it is a fermented soy sauce. More particularly, it is intended to provide a process for producing the fermented soy sauce characterized by preparing soy sauce koji, preparing a soy sauce moromi by adding a salt solution to the soy sauce koji in an amount that allows the ratio of water to be 170 to 450% (V/V), fermenting and maturating the soy sauce moromi, adding the soy sauce koji or the soy sauce koji and the salt solution to the soy sauce moromi during the process of fermentation and maturation and further fermenting and maturating the soy sauce moromi after the addition.
摘要:
A method is described for producing a soy sauce powder by mixing soy sauce oil and an emulsifier such as glycerin fatty acid ester with a soy sauce, agitating the mixture, allowing the mixture to stand still, separating the mixture into an oil phase and an aqueous phase so as to obtain an aqueous phase containing soy sauce-derived aroma components at high concentrations, and subjecting the obtained aqueous phase to spray drying.
