TL;DR: In 1989, JPO&Japio as mentioned in this paper proposed a method to suppress peculiar odor emitted from an enzyme and improve the enzyme resistance to the chlorine present in city water, by adding a particular amt. having inclusion capability to an enzyme- contg. powdered detergent.
Abstract: PURPOSE: To suppress peculiar odor emitted from an enzyme and improve the enzyme resistance to the chlorine present in city water, by adding a particular amt. of each of a sulfite and a compd. having inclusion capability to an enzyme- contg. powdered detergent. CONSTITUTION: A powdered detergent having improved detergency is produced by incorporating a protease, a cellulase, a lipase, etc. 0.1-5wt.% sulfite (e.g., sodium sulfite) and 0.1-5wt.% compd. having inclusion capability are added to the detergent to suppress enzyme odor. Representative examples of the compds. having inclusion capability include β-cyclodextrin, methylated β- cyclodextrin, α-cyclodextrin and γ-cyclodextrin. Thus it is possible to mask enzyme odor without the necessity of increasing the amt. of a perfume or using a special perfume. COPYRIGHT: (C)1989,JPO&Japio

TL;DR: In this paper, the corrosion inhibition of aluminum alloy 2024-T3 by two organic compounds, 5,5′-dithiobis-(2-nitrobenzoic acid) (ER) and sodium sulfite (SUL), in 3.5% NaCl was investigated at various temperatures using electrochemical techniques, such as impedance spectroscopy (EIS) and potentiodynamic polarization.

TL;DR: The results revealed that the pH could be maintained at a relatively high level for an optimized pH-buffering effect when Na2SO3 was added before the reaction of Xyl-Phe and the conversion of N-(1-deoxy-d-xylulos-1-yl)-phenylalanine was successfully improved.

TL;DR: Protein isolates from succinylated, maleylated and dimethylglutarylated flours were highly water-soluble, and did not coagulate by heating, while sensitivity of proteins in isolates to calcium ions was not affected by acylation or sodium sulfite treatment of the flour.
Abstract: Maleylation, succinylation, dimethylglutarylation, and sodium sulfite treatment of cottonseed flour increased protein extraction from the flour in suspension, and precipitated more protein in the extract at pH 4.0, compared to unmodified flour processed through conventional methods. However, acetylation decreased protein extraction and precipitation at this pH. Protein isolates from succinylated, maleylated and dimethylglutarylated flours were highly water-soluble, and did not coagulate by heating. Acetylation decreased heat coagulability of the resulting protein isolate, but did not affect water solubility of the isolate. Treatment of the flour with sodium sulfite markedly increased heat coagulability of the isolate, and decreased its solubility. Oil absorption capacity of the isolate was increased slightly by dimethylglutarylation, but other treatments did not affect the capacity significantly. Sensitivity of proteins in isolates to calcium ions was not affected by acylation or sodium sulfite treatment of the flour.
