Antimicrobial coating on quality attributes of sausage during refrigerated storage

Edible coating based on carboxymethyl cellulose (CMC) environmentally friendly. Addition on Kecombrang (Nicolaia speciosa) extract used to be antimicrobial and antioxidants coating. CMC- based edible coating added with antimicrobial of kecombrang was used to reduce the oxidative and microbial degradation sausages stored at refrigerator at 10°C for 12 days. The cmc coating reduced malonaldehyde substances and peroxide value by 0.88 mg.kg and 92.29%, respectively, compared with the controls. The moisture barrier effect was significantly better for the CMC coating compared to the control. The CMC coating of sausages inhibits the growth of either the total plate counts of Bacillus cereus, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeroginosa. Data show that cmc can effectively be used as a natural antioxidative and moisture barrier coating to extend the quality and shelf life of sausages.

Effect of wheat bran and dried carrot pomace addition on quality characteristics of chicken sausage.

ObjectiveEffect of addition of wheat bran (WB) and dried carrot pomace (DCP) on sensory, textural, colour, physico-chemical and nutritional characteristics of chicken sausage were evaluated.MethodsWB and DCP were used as a source of dietary fibre at 3%, 6%, and 9% level individually. Different quality attributes of sausages were estimated. One product from each source with very good sensory acceptability was selected to analyze dietary fibre content and shelf life under refrigerated storage.ResultsSensory acceptability of 3% fibre enriched sausage was comparable with control and a further increase in fibre level resulted in a decrease in sensory acceptability. Fibre enriched sausages were significantly harder and less cohesive than control sausage. Significant increase in gumminess and chewiness was observed at 6% level in WB treated sausages and 9% level in DCP treated sausages. Moisture content decreased significantly in all treated sausages, protein content decreased significantly in DCP-2 and DCP-3 sausages while fat content decreased in all WB and DCP-3 treated sausages in comparison to control. The fibre enriched sausage had significantly higher dietary fibre and lower cholesterol content. Cooking yield and emulsion stability increased in treated sausages and a significant difference was noticed at 6% level in both types of sausages. pH of WB treated sausages was significantly higher and DCP treated sausage significantly lower in comparison to control.ConclusionThe results of present study indicate that fibre enriched chicken sausage with moderate acceptability can be developed by incorporating WB and DCP each up to 9% level. Chicken sausage with very good acceptability, higher dietary fibre content and storability up to 15 days at refrigerated temperature can be developed by incorporating WB and DCP at 6% level each.

Effects of Dietary Fiber and Stevioside Mixture on Quality Attributes of Sausage and the Blood Properties of Rats

This study was conducted to examine the physiochemical characteristics (PC) of a sausage with added dietary fiber and stevioside mixture, as well as the blood properties (BP) of rats with feeding of the sausage. There were no significant differences between the control and the treatments in the PC; in case of treatments, as additive contents of dietary fiber (1-3%) and stevioside (0.05-1.5%), redness (<TEX>$a^*$</TEX>) gradually increased, but yellowness (<TEX>$b^*$</TEX>) rapidly decreased (p<0.05). The pH level and water holding capacity (WHC) also tended to decrease. Thiobarbituric acid reactive substances (TBARS) were of little change. However, the texture of sensory evaluation and the adhesiveness of texture analysis had significantly low values (p<0.05). BP, such as blood sugar, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol and triglyceride (TG), did not increase and total cholesterol (TC) actually decreased (p>0.05). However, body weights of rats increased with treatments. Overall, it is suggested that adding dietary fiber and stevioside mixture to sausages can moderately improve the redness, and also reduce the levels of sugar, cholesterol and neutral lipids in the blood without noticeably affecting the WHC, oxidant stability, appearance, and taste.

Gelatin Coating on Quality Attributes of Sausage during Refrigerated Storage

Gelatin-based edible coating was used to reduce the oxidative degradation of low-fat sausages (LFSs) stored at <TEX>$4^{\circ}C$</TEX> for 8 wk under vacuum packaging. The gelatin coating reduced thiobarbituric acid-reactive substances and peroxide value by 21.5 and 26.5%, respectively, compared with the controls. The moisture barrier effect was significantly better for the gelatin coating compared to the control. The gelatin coating reduced moisture loss in sausages by 32.6% over the control. However, the gelatin coating of sausages did not inhibit the growth of either the total plate counts or L. monocytogenes. Data show that gelatin can effectively be used as a natural antioxidative and moisture barrier coating to extend the quality and shelf life of sausages.

Effect of electron beam irradiation and storage on the quality attributes of sausages with different fat contents

Sausages with different fat contents (16 or 29%) were purchased from local stores, vacuum-packaged in oxygen-impermeable bags, and irradiated at 0 or 5 kGy using a linear accelerator. The changes in quality attributes of irradiated sausages were determined during storage at 4 degrees C. The 2-thiobarbituric acid-reactive substance values of sausages were not affected by fat content but were increased after irradiation (5 kGy). Storage for 60 d increased the 2-thiobarbituric acid-reactive substance values of nonirradiated sausages (P < 0.05) but had no effect on irradiated sausages. The numbers of volatile compounds and the amounts of total volatiles were increased by irradiation in both the high-fat (29% fat) and low-fat (16% fat) sausages. Dimethyl sulfide was detected only in irradiated sausages, regardless of fat content (P < 0.05), but it disappeared after 60 d of storage. Pentane and 1-heptene were detected only in irradiated samples after 60 d of storage. Low-fat sausages had greater L* values, but had lesser a* and b* values than high-fat sausages. Irradiation and storage had little effect on either the exterior or interior color (L*, a*, and b* values) of sausages. Fat content had no effect on the sensory variables of sausages, regardless of irradiation and storage. However, irradiated sausages had significantly stronger off-odors and off-flavors than nonirradiated sausages regardless of fat content (P < 0.05). This indicated that fat content in sausages had a minimal effect on the quality of irradiated sausages during storage.

Effect of Chemically Modified Soy Proteins and Ficin‐tenderized Meat on the Quality Attributes of Sausage

ABSTRACT: The purpose of this investigation was to use ficin‐tenderized meat and cysteine‐modified soy proteins in the production of bologna and to evaluate the effect of these modifications on water‐holding capacity (WHC), emulsion stability (ES), texture, and protein solubility. The effect of ficin on meat protein was also evaluated by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis (SDS‐PAGE). Results indicated that both ficin‐tenderized meat and modified soy proteins substantially improved WHC, ES, and other quality factors. SDS‐PAGE results showed the disappearance of several protein bands in ficin‐treated meat. Solubility of meat proteins increased when ficin was used for meat tenderization. The results of this study indicated that some quality attributes of meat products can be improved by enzymatic and chemical modification of protein sources in the manufacture of meat products.
