RATIONAL DOSE OF THE CAVIAR COMPONENT AND CITRIC ACID IN THE CAVIAR SAUCE RECIPY USING OFF-STANDARD ROE OF THE PIKE
The article focuses on the investigation of four variants of the caviar sauce "Nezhnost" using mayonnaise, different doses of the caviar component (off-standard unscreened caviar of the pike caught in autumn) and citric acid. The idea of developing recipe variants is connected to changing percentage of off-standard caviar (minus 5%) and mayonnaise portion (plus 5%). Analysis of organoleptic and physico-chemical indices of caviar sauce samples with different doses of introducing the caviar component (76.5; 71.5; 66.5 и 61.5%) showed that only one sample with 71.5% of caviar component corresponded to the requirements of GOST 31761-2012 "Mayonnaises and mayonnaise causes". In order to eliminate bitterness in the caviar sauce samples, as well as to prevent the deep oxidation process of fat, citric acid was introduced into the formulation in different amounts: 0 (control), 0.1; 0.3 and 0.5%. According to organoleptic and physico-chemical indices, the only sample with citric acid dose 0.3% (caviar component dose - 71.5%) corresponded to the requirements of GOST 31761-2012. In order to determine the stage of product readiness there was studied the process of accumulation of fermolent titrated nitrogen in the caviar sauce samples. Introduction of citric acid was stated to inhibit the production process. Maturation period of caviar sauce with citric acid dose 0.3-0.5% made 20 days. Chemical composition of a sample with citric acid dose 0.3%, most correspondent to GOST requirements, was determined as following: content of water - 61.1%; protein - 12.4%; lipids - 22.6%; carbohydrates - 2.3%; minerals - 1.5%. Sample energy value made 241.6 kcal. According to such microbiological indices as amount of mesophilous aerobic and facultatively anaerobic microorganisms and bacteria belonging to a coli bacillus group, this sample of caviar sauce corresponded to the Sanitary-epidemiological requirements 2.3.6.1079-01. Using off-standard unscreened pike roe of autumn catch as raw material for producing the new protein caviar product has been found possible.
