Initial Storage

To develop the utilization of lactic acid bacteria in Chinese-style sausage, Lactobacillus plantarum and a commercial culture (DS-66) were used as a starter cultures for manufacturing Chinese-style sausage. The products were vacuum packaged and stored at 3 or 25°C. The results showed that the pH value and residual sodium nitrite of the sausage significantly declined as storage time increased (P< 0.05). However, the thiobarbituric acid (TBA) and volatile base nitrogen (VBN) values gradually increased as storage progressed. Lactic acid bacteria propagation increased rapidly during the initial storage time and then decreased slightly after 4 weeks of storage. The sausage inoculated with one of the starter cultures had a lower pH value and could suppress the TBA and VBN values, dissipating residual sodium nitrite, and could inhibit spoilage bacteria during the storage time.

This experiment was conducted to determine the ensiling characteristics and microbial changes of fodder ramie silage treated without additive (Control), or with molasses (M), lactic acid bacteria (LAB), and mixtures of lactic acid bacteria and molasses (LABM). Triplicate samples were randomly opened on days 0, 3, 7, 14, 28 and 60 of ensiling for sampling and the contents were processed for quality assessment and laboratory analysis. Compared with control silage, addition of M and LABM decreased pH and butyric acid while increasing lactic acid during ensiling (P < 0.05). For the LAB treatment, the pH value declined slowly at initial days then kept relatively stable at about 5.39 and the concentration of lactic acid increased for the first 7 days then maintained stable until day 60. The control silage showed a rise in pH and a significant decline in lactic acid concentration at later stage. Microbial changes had similar trend during ensiling for all the treatments where the lactic acid bacteria increased at initial days then showed a decline at later stage. Furthermore, LAB treatment had the highest (P<0.05) lactic acid bacteria population at almost all ensiling periods. It was concluded that both M and LABM treatment can improve the fermentation quality of fodder ramie silage to some extent, but the effects of adding lactic acid bacteria still need further research.

Dry Fermented Sausage

Dry fermented sausage is popular among the world because of its rich nutrition and unique flavor. Starter cultures play an important role in the quality of dry fermented sausage. In this study, probiotics lactic acid bacteria Lactobacillus delbrueckii N102, Latilactobacillus sakei H1-5, Debaryomyces hansenii Y4-1, and Wickerhamomyces anomalus Y12-3 were isolated from food-borne materials. The physicochemical properties, microbial populations, TBARS, lipolysis, proteolysis, and volatile flavor compounds of dry fermented sausages with different starter cultures were evaluated comparatively during the ripening process. The results showed that both L. delbrueckii N102 and L. sakei H1-5 grow well and could rapidly reduce the pH value of the products. At the same time, they could significantly reduce the number of Enterobacter putrefaciens, so as to ensure the safety of the products. In addition, the strains N102 promoted the formation of flavor compounds 2,3-butanedione, 3-hydroxy-2-butanone, and carnosine, whereas taurine content of batch H1-5 was significantly increased, while yeast y4-1 and y12-3 could also grow faster in sausage and promoted the esters and alcohols formation such as ethyl acetate and linalool, with the formation of γ-aminobutyric acid by y4-1. Compared with lactic acid bacteria, yeasts showed to contribute more in flavor formation and effective inhibition of lipid oxidation. The starter cultures played different roles in flavor contribution and had obvious differentiation in the ripening process of dry fermented sausage.

Greater lizardfish (Saurida tumbil) is known to contain endogenous formaldehyde content. Formaldehyde can kill spoilage bacteria, pathogens, and molds. However, this compound is also carcinogenic. The present research was conducted to determine the profile of endogenous formaldehyde and deterioration in the quality deterioration of greater lizardfish during frozen storage. The sample was provided from TPI Cituis, Tangerang, Banten. Sampling and analysis to determine the formaldehyde profile and fish deterioration were conducted once in a month for four months. The samples were then analyzed for formaldehyde profiles (formaldehyde, TMA, TMAO, and DMA) and quality deterioration profiles (TVB-N, acidity, TPC, and organoleptic plates). The results showed that greater lizardfish had 8.62±3.4 ppm formaldehyde content, which increased in the first-month storage and then decreased in subsequent months. The content of TMA and TMAO increased during frozen storage. Greater lizardfish quality deterioration analysis during storage showed the increasing of TVB-N content. Based on the organoleptic score, greater lizardfish can be stored for up to three months. The pH value and total bacteria of greater lizardfish increased in line with storage time.

   The aim of this research was to examine the microbiological quality of calf starter pellet added with fermented cabbage waste after stored for 0, 4, and 6 weeks. The materials used in this research consisted of cornmeal, rice bran, soybean meal, molasses, mineral mix, and fermented cabbage waste. This research used Completely Randomized Design with 4 treatments and 3 replications. The mixed calf starter pellet consisted of 100% calf starter and 6% of fermented cabbage waste, and then stored for 0 weeks (P0), 2 weeks (P1), 4 weeks (P2) and 6 weeks (P3). The observed microbial qualities were the total lactic acid bacteria and the presence of gram positive and negative bacteria in the mixed calf starters. The total lactic acid bacteria were analyzed descriptively, while the presence of gram bacteria was analyzed with analysis of variance followed with Duncan’s test. The result of this research showed that an increase in storage time would result in lower lactic acid bacteria population, while the gram-positive and negative bacteria was not significantly affected. The research concluded that 6-weeks stored calf starter pellet added with 6% of fermented cabbage waste could maintain its lactic acid and gram-positive bacteria population, while also reducing its gram-negative bacteria population as well.

The use of mesophilic lactic acid bacteria (LAB) in the manufacture of Feta cheese was studied. Five selected mesophilic strains, confirmed as Lactobacillus plantarum (2 strains), Lb. paracasei subsp. paracasein Lb. brevis and Lactococcus lactis subsp. lactis, isolated from ripened Feta and Teleme cheeses, were used in 7 different combinations, alone or in combination with Lb. delbrueckii subsp. bulgaricus and Streptococcus thermophilus (the control combination) for the manufacture of Feta cheese. Each combination of strains was used to prepare four different batches of Feta cheese, keeping all the other production parameters according to the traditional technology. The cheese batches were analyzed for bacteriological, chemical and sensory characteristics. The results showed that the populations of lactobacilli and lactococci increased from the beginning of the cheese manufacture reaching a population of more than 7.0 log10cfu/g. This level was maintained during the whole ripening period (60 days) and during the subsequent 60-day storage period. Only in batches prepared with the control combination F8 {Str. thermophilus I Lb. delbrueckii subsp. bulgaricus), did the population of LAB decline to 6.0 log10cfu/g at the end of the ripening period. Also, except for the yeast population which increased, in all other bacterial groups tested (coliforms, staphylococci, total contaminating bacteria, psychrotrophic bacteria, proteolytic and lipolytic bacteria) populations gradually decreased during the ripening period. Results of the chemical analysis showed a sharp increase in acidity (the cheese pH dropped to ca. 4.5 within 3-4 d) and, whereas the values of other chemical indices (moisture content, fat content and NaCl) were stabilized between the 15* and 30* day of ripening, proteolysis (nitrogen soluble in 12% TCA) and lipolysis (ADV) progressed throughout ripening. The assessment of the overall acceptance by the sensory panel was between "very good" and "excellent" for all cheeses. This suggests that the selected mesophilic starter cultures can be used alone or in combination with the traditional culture {Lb.delbrueckii subsp. bulgaricus I Str. thermophilus) in the production of Feta cheese, as the results of this work indicate that the wild (autochthonous) strains of Lb. plantarum and Lc. lactis subsp. Lactis are well adapted to the environmental conditions that prevail in Feta cheese. Batches prepared using these mesophilic starters received the highest score in the assessment of organoleptic quality of Feta cheese. Very good results were also obtained using the combination of the mesophilic starters Lb. brevis and Lc. lactis subsp. lactis or Lb. paracasei subsp. paracasei and Lc. lactis subsp. lactis alone or in combination with Lb. delbrueckii subsp. bulgaricus and Str. thermophilus.
