Effect of washing treatment on quality characteristics of burger made from spent laying duck meat

Experiment was carried out to investigate the influence number of washing treatment (without, single and double washing) on the quality characteristics and acceptability of duck burger made from spent laying Khaki Campbell duck meat. The chemical composition of burger at different number of washing treatment was varied in terms of moisture content, fats and protein content. The number washing cycles treatment were found to increase moisture content and reduce fat and protein content significantly. Increase number of washing treatment showed significantly higher (p <0.05) lightness (L*), hardness, diameter shrinkage and cooking loss. As for sensory evaluation, there was no significantly difference (p >0.05) within the sample and control (chicken burger). The spent laying duck Khaki Campbell produced using different number of washing treatment may have a possible use as raw material in restructured meat products such as burger.

PENGARUH KONSENTRASI PATI KENTANG TERHADAP KARAKTERISTIK FISIKOKIMIA DAN ORGANOLEPTIK NUGGET IKAN PATIN-TEPUNG NANGKA MUDA

Nugget merupakan salah satu produk restructured meat dengan prinsip penyatuan kembali potongan-potongan daging menjadi suatu bentuk utuh yang kompak dengan menambahan bahan pengisi (filler) dan pengikat (binder) yang dapat menentukan kualitas nugget. Pengolahan ikan patin menjadi nugget dengan modifikasi penambahan tepung nangka muda merupakan salah satu upaya diversifikasi hasil perikanan dan pertanian, meningkatkan juiciness, serta dapat meningkatkan kandungan serat nugget ikan patin. Penelitian pendahuluan pembuatan nugget ikan patin dengan proporsi 30% tepung nangka muda menunjukkan terjadinya penurunan tingkat kekenyalan dan nugget yang dihasilkan menjadi kurang kompak. Upaya peningkatan kualitas nugget dapat dilakukan dengan penambahan pati kentang sebagai filler dan binder dalam nugget. Tujuan penelitian ini adalah untuk mengetahui pengaruh konsentrasi pati kentang terhadap sifat fisikokimia dan organoleptik nugget ikan patin-tepung nangka muda. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) faktor tunggal yang terdiri dari enam taraf konsentrasi pati kentang, yaitu 3, 6, 9, 12, 15, dan 18% (b/b ikan patin-tepung nangka muda). Pengujian terhadap karaktertistik fisikokimia meliputi uji kadar air, WHC, daya serap minyak, kestabilan emulsi, tekstur, dan warna. Hasil penelitian menunjukkan adanya pengaruh konsentrasi pati kentang terhadap kadar air, WHC, daya serap minyak, tekstur, dan warna nugget. Peningkatan konsentrasi pati kentang dapat menurunkan kadar air, daya serap minyak, dan cohesiveness (konsentrasi pati kentang 15-18%), serta meningkatkan WHC, hardness, dan cohesiveness (konsentrasi pati kentang 3-12%).

Different contents of fat in pork-based nuggets: a sensorial perspective

With an increasingly busy lifestyle, consumers are looking for convenience, with products that are easy and quick to prepare. In this context, we highlight the restructured meat products breaded like nuggets. The study aimed to develop and evaluate nuggets made with pork by a sensory method. Three formulations with different concentrations of swine fat were prepared. The microbiological evaluation of the formulations was carried out, which did not present microbial contamination. The sensory acceptability assessment was conducted using a 9-point hedonic scale for the attributes softness, flavor, aroma, crispness, appearance, and overall impression of the product. Also, to assess the opinion of consumers regarding the product, a 5-point purchase intention test was applied. The results obtained show that the three samples obtained a score greater than or equal to 7 (I liked it regularly) by more than 90% of the judges. No score lower than 5 were attributed to the formulations, indicating low rejection of the products. Purchasing intentions were also high, with the percentage of judges indicating scores 4 and 5, corresponding to the terms “probably would buy” and “certainly buy” was 86.4, 81.8, and 84.5% for sample A, B, and C, respectively. The work showed that pork-based nuggets with different fat contents obtained excellent acceptability and purchase intention, presenting themselves as a potential alternative for insertion in the consumer market.

Fortifying Bakso (Restructured meat product) with potential encapsulated functional strategies – a mini review

This review revisits the Indonesian Bakso, a restructured meat product that is well preferred by wide ranges of social economy classes of the Indonesian community. Bakso has been a very good low-cost protein source for all. By understanding the complexity of the colloidal structure of Bakso that is constructed by the protein matrix and swelling starch granule interactions, it is also made clear in this review that Bakso has the potential for being more than just a low-cost protein source meal enjoyed by all. The colloidal complexities of the food system in Bakso allows it to entrap fortifications of bioactive compounds, bringing Bakso to the realm of functional foods. Various simple attempts have been made to improve the eating quality of Bakso by simple substitution of the starch with other plant-sourced starches that have functional properties. Effectiveness of these attempts had not scratched the surface of elevating Bakso into the functional food world, therefore it is an opened option to explore the potential of bringing encapsulation of functional components in this mini review processes into the mix. The variables in terms of bioactive functions, sources, polarities, solubilities and reactivities of the various compounds and encapsulating materials is still a large opportunity for further exploration. With encapsulation in play, this opens the doors of refitting Bakso with more varieties of bioactive compounds, and the elements of modifications that can be made to elevating Bakso in the functional food world.

Can Carob-Fruit-Extract-Enriched Meat Improve the Lipoprotein Profile, VLDL-Oxidation, and LDL Receptor Levels Induced by an Atherogenic Diet in STZ-NAD-Diabetic Rats?

Carob fruit extract (CFE) has shown remarkable in vitro antioxidant properties and reduces postprandial hyperglycemia and hyperlipidemia in healthy animals. Development of functional meat products that contain bioactive components are presented as a great nutritional strategy. Until now, the effect of the consumption of restructured meat enriched with CFE in a murine model of diabetes has not been investigated. The objective of this study was to evaluate the effect on glycemia, lipemia, lipoprotein profile, Ldlr, arylesterase (AE), and very low-density lipoproteins (VLDL) and liver oxidation in streptozotocin-nicotinamide (STZ-NAD) growing Wistar diabetic rats fed restructured meat in the frame of a high cholesterol/high saturated-fat diet. In the present study, three groups (D, ED and DE) were fed cholesterol-enriched (1.4% cholesterol and 0.2% cholic acid) and high saturated-fat diets (50% of total energy from fats and 20.4% from saturated fatty acids). Rats were subjected to a STZ-NAD administration at the 3rd week. Group D did not receive CFE, while ED and DE rat groups received CFE before and after the diabetic induction, respectively. After eight weeks, D rats showed hyperglycemia and hypercholesterolemia, an increased amount cholesterol-enriched VLDL (β-VLDL), IDL and LDL particles and triglyceride-enriched HDL. ED and DE partially blocked the hypercholesterolemic induction with respect to D group (p < 0.001) and improved glycemia, cholesterol levels, lipoprotein profile, Ldlr, plasma AE activity and liver oxidation (p < 0.001). Fecal fat, moisture and excretion were higher while dietary digestibility was lower in ED and DE vs. D counterparts (p < 0.0014). In conclusion, CFE-enriched meat shows, for the first time, hypoglycemic and hypolipidemic effects in STZ-NAD animals fed high cholesterol/high saturated-fat diets. Likewise, it manages to reverse possible diabetes lipoprotein alterations if CFE-enriched meat is consumed before pathology development or improves said modifications if Type 2 Diabetes Mellitus is already established.
