    Notes: Sodium acid pyrophosphate (SAPP) is currently used by the sausage industry to accelerate development of cured meat color. The cured color accelerator was examined, through sensory evaluation and instrumental measurements, for its effects on the texture of frankfurters. The effects of SAPP on other sensory properties and on chemical and physical characteristics were also examined. SAPP was found to slightly improve texture by increasing springiness, hardness, and awareness of skin, and by reducing oiliness. SAPP had no detrimental effects on texture. SAPP caused a slight improvement in flavor by enhancing beef, salt, smoke, and seasoning flavors, and by diminishing fat flavor. and mouthfeel. However, the presence of SAPP resulted in intensified sour flavor and decreased aroma and flavor of pork. SAPP did not greatly reduce residual nitrite levels or increase the development of meat color. SAPP effectively lowered viscosity of the emulsion and held emulsion temperature down during emulsification. Unlike alkaline phosphates, SAPP did not improve moisture retention or cook yields; it had no effect on proximate analysis. SAPP did cause an increase in exudate formation in stored vacuum-sealed packages of frankfurters.

    Notes: Five levels (0, 5, 10, 15, 20%) of partially defatted chopped beef (PDCB) were substituted for lean in fermented beef stick sausage to evaluate changes over a 90 day period (24°C). Replacement of 0, 5, 10, 15, and 20% of the lean with PDCB did not affect percentage of fat, moisture, protein, moisture:protein ratio, or aw of the final product. TBA values were different (P〈0.05) between storage periods, but were all lower than those associated with oxidative rancidity. Warner-Bratzler shear values increased incrementally with increasing PDCB but were still within acceptable limits. Sensory profiles indicated that concentration of PDCB in the formulation had no effect on aroma, mouthfeel, taste, or texture of the product over storage time.

    Notes: Prerigor trimmings from four lean cuts of pork carcasses (n = 3) were used to manufacture three replications of low-fat (10%) fresh pork sausage containing konjac flour gel, at 0, 10 or 20% levels and compared to a 40% fat control. Treatment sausages showed equal or improved cooked yields, slightly higher shear force (kg/g) and sensory textural attributes, but rated slightly lower in juiciness. As konjac flour gel levels increased, shear force and sensory textural attributes became more like the control. Storage time had minimal effect on quality and shelf life. Acceptable low-fat, prerigor pork sausage can be produced with 10–20% incorporation of konjac flour gel.

    Notes: Effects of sodium ascorbate (Na ascorbate) and sodium erythorbate (Na erythorbate) on vitamin B]2 content of cured, cooked ham were investigated. Paired hams were injected with cure solution containing no curing accelerators or with cure solution containing Na ascorbate or Na erythorbate (3.28, 6.56, 9.84 g/L). There were no differences between vitamin B12 contents of hams containing added curing accelerators and paired controls, indicating that B12 was not destroyed by either Na ascorbate or Na erythorbate. Analysis of ascorbate, dehy-droascorbate, isoascorbate and dehydroisoascorbate showed ascorbate to be the only substance present in Na ascorbate-treated hams and isoascorbic acid to be the only substance present in Na erythorbate-treated hams.

    Notes: Frankfurters, with and without 0.5% sodium tripolyphosphate (STPP), containing 3.5% vital wheat gluten (VWC), calcium reduced nonfat dry milk (RNFDM) and soy protein concentrate (SPC) were processed to an internal temperature of 72° or 82°C and compared to an all-meat control. Processing yields, textural profile analysis (TPA) and sensory textural attributes were not different among protein treatments, but SPCand VWG contributed slight-to-moderate off-flavor. VWG and SPC franks were acceptable, but slightly less desirable than the control and RNFDM treatments. Franks processed to 82°C were more desirable, but at the expense of reduced yields. STPP did not affect yields, but increased sensory firmness and TPA fracturability and hardness. VWG, RNFDM and SPC were comparable to the control for most traits studied, but alterations in spice formulation are needed to improve VWG and SPC flavor.

    Notes: Ground beef with or without 3% added glandless cottonseed flour (GCF) was over-wrapped with polyvinyl chloride film and displayed up to 6 days in a retail case. Aerobic plate counts were slightly higher (P 〈 0.05) for ground beef with GCF at day 0, with no difference (P 〉 0.05) found at days 3 and 6. At day 6, a combination of Pseudomonas and heterofermentative Lactobacillus spp. made up a major part of the microflora of ground beef without GCF whereas heterofermentative Lactobacillus spp. constituted a dominant part of the microflora of ground beef with GCF. Discoloration and lipid oxidation in ground beef during display were markedly reduced by addition of 3% GCF.

    Notes: Three separate batches of ground beef containing 25% fat were extended to 0, 10, 20 and 30% by weight with rehydrated defatted textured soy protein (TSP). Five samples of each soy level were wrapped in a polyethylene oxygen-permeable film and stored at 5°C for 4 days. Samples were analyzed daily for changes in bacterial numbers (total plate counts and coliforms), pH, titratable acidity, proximate analysis, ninhydrin reactive material, carbohydrate content, and gas liquid chromatographic (GLC) analysis of individual amino acids to assess spoilage in TSP extended ground beef. Total bacterial numbers increased significantly as days of storage progressed and in proportion to added TSP. Coliforms increased during storage, but not proportional to increased levels of soy protein. Spoilage in soy extended samples, as determined by off-odors and bacterial numbers, was evident by day 4 as total bacterial counts approached 108 bacteria/g. The differences of pH were significant among soy levels, but did not change appreciably during storage. Titratable acidities were not significantly changed with increases in soy protein. As soy level increased, percentages of moisture and ash increased, but percent fat decreased. No differences were noted for percent protein. Total carbohydrate as determined by proximate analysis increased with TSP levels. Concentration values for carbohydrates were proportionately larger with added amounts of TSP, but varied little during 4 days of storage. Ninhydrin reactive material differed significantly among samples, but not proportionate to added TSP, and decreased in the 30% soy level between days 3 and 4. Decreases in individual amino acids could not be shown from the qualitative results obtained by GLC analysis. Further investigation is suggested using more definitive measuring techniques to determine the factor(s) causing accelerated spoilage in soy extended ground beef.

    Notes: Instrumental and sensory evaluations were conducted on frankfurters manufactured with an increased monounsaturated/saturated (M/S) lipid ratio and 25% less fat than control. The M/S ratio was altered by using lean and fat from pigs fed 0%, 10%, or 20% canola oil (CO) which is high in oleic acid. Incorporation of 10% and 20% CO pork tissue into the product decreased saturated fat by 11.0% and 18.6%, respectively. Instron texture analysis indicated slight increases in cohesiveness with elevated CO, whereas decreasing fat increased gumminess and chewiness. Sensory evaluation demonstrated that the overall palatability ratings of the test frankfurters were similar to the control product. Frankfurters with significantly less total fat and saturated fatty acids without adverse sensory and storage characteristics were produced.
