Abstract Within the rich diversity of South American freshwater fish, Colossoma macropomum (Characiformes: Serrasalmidae), known as tambaqui, cachama or blackfin pacu, can reach 30 kg, is a traditional product in regional fish markets and has drawn attention farmers since 1930s. Considerable progress achieved different fields aquaculture science contributed to growth tambaqui production. Tambaqui proven suitable for both monoculture polyculture systems, extensive intensive production systems...

The effects of sodium tripolyphosphate, ascorbic acid, erythorbate, and natural antioxidants — green tea extract propolis on the physicochemical stability mechanically separated meat (MSM) tilapia stored for 180 days at −18 °C were investigated. proximate composition, lipid oxidation (thiobarbituric acid reactive substances, TBARS), pH, water activity color (L*, a*, b*, c* °h) analyzed. Frozen storage affected composition MSM by reducing protein content increasing moisture contents. All...

Currently, there is a strong emphasis on improving the nutritional quality of foods while simultaneously addressing environmental concerns and food waste. This study aimed to utilize by-products from tilapia salmon filleting produce oils, incorporating them into ice creams as substitutes for saturated fats. The oils were extracted through grinding, cooking, centrifugation, followed by refining process. They then added cream formulations at proportions 0%, 2.5%, 5%, 7.5% 10%, replacing cream....

The creation of quails has increased in Brazil and the world, for production meat eggs. However, industries have not invested use slaughter by-products. objective was to investigate stability pre-fried chicken nuggets, quail with mechanically separated nuggets. Initially, color dough were analyzed, yield calculated. nuggets developed centesimal composition determined. Soon after, analyses pH, water activity, lipid oxidation (TBARS, substances reactive thiobarbituric acid), internal external...

The pirarucu (Arapaima gigas), an Amazonian fish with high protein content, is a promising raw material for burger production, although it presents low levels of fiber and bioactive compounds. In contrast, the peel yellow pitaya (Selenicereus megalanthus), rich in antioxidants, often discarded, despite its potential as functional ingredient. This study aimed to produce flour (PPF) evaluate application formulation burgers. PPF was obtained through ethanolic extraction (60%, 1:1 m/v), followed...

ABSTRACT This work considers the hypothesis of using Parallel Factor Analysis (PARAFAC) for relating consumer acceptance to descriptive attributes by employing three‐way external preference maps. A pilot case study with a real data set from six commercial samples grape juice was conducted. The results revealed that PARAFAC useful attributes, simultaneously considering various analyzed maps provided general interpretation data, thereby making it possible relate preferences, sensorial and...

In this study, we evaluated the effect of minced fish (MF) inclusion on acceptance tilapia sausages. One hundred consumers participated in sensory test relation to attributes appearance, color, aroma, flavor, texture, overall impression, and purchase intent. The tests were conducted using same composition ingredients, varying only raw material (MF fillet), resulting 5 different formulations. To represent results attributes, generated internal preference maps through principal component...

This study evaluated the effect of ractopamine (RAC) on performance finishing pigs and meat quality these animals. Seventy crossbred (35 barrows 35 females) selected for high gain lean meat, with initial weight 77.1±0.32 kg were distributed in randomized blocks five treatments (0, 5, 10, 15, 20 ppm RAC diet) seven replications during 28 days. The experimental unit was represented by a male female pig. Regarding variables, there linear increase final increasing levels RAC, as well average...
