Title: Production of hydrolyzed seasoning
Inventor: FUJII MIKIO
IPC: A23L27/21
Filed: 1993-08-02
Abstract: PURPOSE:To produce a hydrolyzed seasoning having high tastiness without containing an unfavorable chlorinated compound such as dichloropropanol(DCP) or monochloropropandiol(MCP). CONSTITUTION:When an animal protein for a food with a low lipid content is hydrolyzed with hydrochloric acid, any chlorinated compound is hardly produced by carrying out the hydrolysis under mild conditions at a constant level or below. These conditions are achieved by setting hydrolyzing conditions of the protein so as to provide <=1% lipid content based on the protein and <=60% hydrolytic ratio. Since the tasting power of the hydrolyzate hydrolyzed under these conditions is lower than that of the complete hydrolysis, the hydrolyzate having high tasting power can be obtained by supplementing the insufficient hydrolytic ratio according to the hydrolysis with the hydrochloric acid and a proteolytic enzyme in combination. Thereby, the objective seasoning having the high hydrolytic ratio, i.e., the high tasting power without containing the chlorinated compound can be produced.

IPC: H03G3/30
Filed: 1983-10-13
Abstract: PURPOSE:To obtain an automatic gain control amplifier which has less restrictions of a data transmission speed by providing a main amplifier, mean value detecting means, diode, peak value detecting means, and operational amplifier. CONSTITUTION:The main amplifier 1 amplifies a data signal, and the mean value detecting means consists of an emitter follower transistor (TR) 2 which detects the mean voltage value e1 of the data signal output of the main amplifier 1. The diode 3 decreases said data signal output by a forward voltage, and the peak value detecting means consists of an emitter follower TR4 which detects the peak voltage value e2 of the difference voltage between said data signal output and forward voltage. Further, the operational amplifier 6 outputs a gain control signal proportional to the difference voltage e3 between said mean voltage value e1 and peak voltage value e2. Consequently, the TRs 2 and 4 operate at high speeds and it is not necessary to consider the matching between input impedance and output impedance, so the restrictions of the data transmission speed are reduced.
