Inclusion Level

The objectives were to determine effects of salt inclusion on production yields, commercial slicing yields, sensory characteristics, and lipid oxidation of bacon. A total of 144 bellies that ranged in weight from 5.8 to 6.6 kg were selected from 2 different suppliers. Fresh bellies were weighed to determine an initial weight (green weight). Then, bellies were randomly assigned to salt levels of 1.2, 1.5, or 1.8% in the final product and manufactured into bacon. Bacon was stored frozen, in aerobic packages, for approximately 0 d, 30 d, 60 d, or 90 d and analyzed for lipid oxidation. Sensory analysis was conducted approximately 14 d after slicing and again 90 d later. Cook yield was increased (P ≤ 0.05) in 1.2% bacon compared with 1.5 and 1.8% bacon, but slicing yield was 1% unit greater (P ≤ 0.05) in 1.8% bacon compared with 1.2% bacon. Increasing salt content from 1.5 to 1.8% increased the number of bacon slices generated from a slab of bacon by 12 slices and by nearly 16 slices when compared with the 1.2% treatment. Sensory saltiness increased (P ≤ 0.05) as intended salt level increased. Lipid oxidation and oxidized odor and flavor intensity was not different among salt treatment levels within any storage period. Reducing salt from 1.8 to 1.2% in bacon can adversely affect slicing yield, but was not detrimental to cook yield and did not reduce the rate of lipid oxidation of bacon.

The aim of this work was to investigate the effect of pre-cure freezing on the physicochemical, texture and sensory characteristics of raw and dry-cured hams. Both, refrigerated (R) and pre-cure frozen (F) hams showed the same weight losses during the processing. At the green stage F Iberian hams had lower moisture content, higher values of a* and chroma, lower hardness and chewiness and higher adhesiveness and springiness than R ones. However, at the end of the processing R and F Iberian hams only were different in salt content, F hams showing lower values than R ones. Sensory analysis of Iberian dry-cured ham did not show differences in salty taste. Panelist detected a higher fat hardness and lean pastiness in F than in R hams. The overall acceptability for both groups of dry-cured hams was between average and good.

Significant Protective Effect

Abstract The effect of thyme supercritical extract on oxidative stability of precooked and cold-stored (at 4°C for 6 days) pork chops was analysed. Thyme extract was applied with a marinated process (SF1), or was introduced on the surface of the chops after cooking (SF2). Thyme extract in SF1 samples showed a significant protective effect towards oxidation of lipids during the cooking process. Both processes of thyme application showed potential for lipid oxidation inhibition throughout the refrigerate storage period of precooked pork chops, thus protecting colour and sensory characteristics of the samples. Finally, at the end of storage period, the lowest oxidative changes were determined for SF1chops.

Both pre- and post-rigor beef semimembranosus muscles were ground with salt (0, 2 and 4%) and then subdivided into two treatment groups (freezing and freeze drying) and evaluated during storage of 0, 5, 10 and 15 wk for chemical and sensory traits. Rehydration ratios of pre-rigor freeze-dried beef (salted or unsalted) were not significantly changed during a 15-wk storage period at 25°C. With the addition of 2 and 4% salt, pre-rigor freeze-dried beef was less susceptible (P<0.05) to lipid oxidation (lower TBA values) than post-rigor, freeze-dried beef. Pre-rigor, freeze-dried beef was superior to post-rigor, freeze-dried meat in all sensory traits studied. Differences in TBA values were not significant between pre-rigor and post-rigor, frozen beef treatments at any salt level (0, 2 and 4%). Pre-rigor, frozen beef samples were superior (P<0.05) to conventional post-rigor, frozen meat in panel tenderness and acceptability scores. The TBA values of pre- and post-rigor beef (frozen or freeze dried), in general, increased with increased salt level (0, 2 and 4%). Freeze-dried beef samples (pre- or post-rigor) were less (P<0.05) tender, cohesive, acceptable and more rancid and/or off-flavor than frozen meat (pre- or post-rigor).

Background: The extrusion cooking is the most widely used process so the development and consumption of extruded snack products having health and nutritious benefits would help increase the health status of the population. Objective: The aim of this study was to investigate the effect of storage days on physical, microbial activity and sensory characteristics of extruded snacks and kinetics of extruded snacks. Methods: Extruded snacks were produced by extrusion cooking at optimized conditions of temperature, moisture and screw speed of 110°C, 12% (db) and 200 rpm. The products were packed in lowdensity polyethylene (LDPE) and laminated pouches (LP) and were stored at an accelerated temperature condition of 40 ± 2°C. The storage stability in terms of quality parameters such as moisture, hardness, bulk density, color, lateral expansion, sensory characteristics and total plate count was investigated. Results: An increase (p≤0.05) in the value of moisture, bulk density, a*, and total plate count was observed during the storage period, whereas hardness, L*, b*, ΔE and sensory characteristics showed significant (p≤0.05) decreased order with storage period. No significant effect on the lateral expansion of the extruded product was observed. A significant decrease in total carbohydrate, fat and protein content was found during the storage period. The average sensory score and microbial analysis suggested that extruded snacks packed in LDPE pouches can only be acceptable up to the 60th day and extruded snacks packed in LP can be acceptable to more than 90th day. The kinetics of color and hardness suggest first order kinetics. Conclusion: Overall investigation suggested that extruded snacks were more stable in the LP as compared to LDPE pouches.

Aim: the aim of this study was to determine sensory profile, through the use of just-about-right (JAR) scales and penalty analysis, of Bobolo and Chikwangue from the cassava roots fermented with previously cassava-fermented chips powder (PCFCP). Furthermore, retting time, cyanide content and pasting properties of retted roots were evaluated. Methods: for that, two samples of Bobolo and Chikwangue obtained from two cassava retting methods were studied: a control made from the retting without PCFCP and a product made from retting with PCFCP. Results: retting time was carried out in 48 hours less with PCFCP and 60% of cyanide reduction more than control. No major modifications occurs in pasting properties of paste fermented with PCFCP. The sensory analysis indicated high levels of acceptability for products made from retting with PCFCP. The penalty analysis showed that attributes “too sour” and “too much fermented odor” affected the acceptability of the Bobolo from retting without PCFCP significantly. Conclusion: fermentation of cassava through the use of PCFCP is suitable to improvement of sensory characteristics of fermented cassava by-products.

ABSTRACT: This research aimed to evaluate whether the essential oil of Aloysia triphylla (EOAT) used in vivo as a sedative in the water for transporting fish could increase the oxidative stability of silver catfish (Rhamdia quelen) fillets during frozen storage. The chemical composition of EOAT and of fillets from fish exposed to EOAT (0, 30 or 40µL L-1) were assessed. The pH and lipid oxidation parameters (conjugated dienes, CD; thiobarbituric acid-reactive-substances, TBARS) were evaluated in the fillets throughout the storage period (-18±2oC/17 months). The main compounds found in EOAT were α- and β-citral. Treatment with EOAT did not modify the proximate composition of the fillets, but 40µL L-1 EOAT reduced pH levels when compared to the control fillets (P<0.05). Compared to the control fillets, the fillets from fish treated with 30 and 40µL L-1 EOAT had higher initial CD values (P<0.05), whereas fillets from fish treated with 40µL L-1 EOAT had lower TBARS levels after 6, 9 and 17 months of storage (P<0.05). Results indicated that use of EOAT as a sedative in silver catfish transport water delays the degradation of primary oxidation products (CD) into secondary products (TBARS) in the frozen fillets. This delay in the lipid oxidation rate may increase the shelf life of frozen fillets.

The main role of milk and milk products in the technology of confectionery products (chocolates, caramele-candy products, dairy products, spreads, etc.) is to increase the nutritional value of the final product and to influence some sensory characteristics of quality (appearance, consistence/texture, flavor). In this study, mixtures of milk and cocoa spreads of a new composition with increased content of milk components were produced, and then assessed for sensory quality traits, peroxide value, free fatty acid content and the content of heavy metals (lead, cadmium and copper) during storage from 0-30 to 180 days at room temperature (18 - 20?C). The samples were evaluated using the analytical-descriptive sensory analysis (point system) with description of the dominant properties (appearance-color, surface gloss, consistence-spreadability, dynamic property of melting, the consistence in the oral cavity-oiliness and flavor-odor and taste). The results of sensory analysis were statistically analyzed using two-way analysis of variance MANOVA, LSD and Levene's test. Based on the obtained results it can be concluded that the composition of mixtures of milk and cocoa spreads significantly affects all characteristics, whereas the storage time significantly affects the appearance, consistence, i.e. spreadability and taste of the product.
