Abstract

A research was conducted to investigate the influence of fermentation dose of Saccharomyces cereviceae and sucrose addition on maintaining the physical properties of egg white flour. One hundred and thirty five fresh hen eggs were used in the research which were randomly arranged in a factorial experiment of 3 x 3 according to completely randomized design with 3 replications for each treatment combination.  The first factor was the level of Saccharomyces cereviceae, i.e. 0%, 0,2% and 0,4% w/w, the second factor was the level of sucrose addition, i.e. 0%, 2 % and 4% w/w. The parameters measured were physical properties (rendemen, water content, pH, reduction sugar and color score). Data analysis indicated that increased level of Saccharomyces cereviceae decreased water content, pH, rendemen, reduction sugar, and color score. Sucrose addition improved yield, sugar reduction, color score, but decreased pH of white egg fluor. Physical chracteristics of egg white flour was similar to those of fresh egg white at all of combination of level Saccharomyces cereviceae and sucrose, but low of reduction sugar content and the best color score was obtained at treatment combination of both high level of Saccharomyces cereviceae and low level of sucrose addition.

Abstract

Bacterial decomposition on meat, dairy and fish protein have been carried out extensively but has not been done on egg white.  In order to break the proteins down, the bacteria need to grow well on the medium. This study aims to become preliminary information to determine the growth ability of L. plantarum bacteria in the egg whites with indicators: total bacteria, pH, and, total acids formed by different fermentation treatments. The study was conducted according to completely randomized design using different time of fermentation as treatments (18: 24: 30 hours) on 150 eggs from the same chicken farm, bacteria L. plantarum 0027 FNCC isolated from milk. Replication for each treatment was five. The results showed that fermentation time significantly increased the total bacteria, total acid and decreased pH during the fermentation process.  The difference between total bacteria increase was significant between the 18-hour fermentation time and both the 24 and the 30 h fermentation time, namely 5.884 ± 0.157 log CFU/g, 6.035 ± 0.024 log CFU/g,  and 6.131 ± 0.095 log CFU/g respectively, although the difference between the 24 and 30 h fermentation time was insignificant. The difference of total acid production was significant between the 18 and the 24 and the 30-hour fermentation time, i.e. 0.077±0.014%, 0.014%±0.167 and 0.171 ±0.017% respectively, altohough once again the difference between the 24 and 30 hour fermentation time. pH decrease during the fermentation time process showed a significant difference between the 18-hour fermentation time and the others, namely 7.689±0.035, 6.434±0.501 respectively 6.353±0.65, and again the difference between the 24- and the 30-hour fermentation time was not significant. The 24-hour fermentation time may incrase growth ability ofbacteria L. plantarum on egg white.
