Sensory Attributes and Shelf Life Evaluation of an Instant Soup Powder Fortified with Moringa (Moringa oleifera Lam.) Leaves

Wasting, categorized as either severe or moderate, is a form of child malnutrition that manifests with a low weight-for-height Z-score. Previous treatment methods for moderate wasting, which affects approximately 300,000 children in Kenya, were ineffective as they lacked a mechanism to replace the accelerated loss of lean tissue. Supplementation with leucine, maybe a safe and effective method for treating moderate wasting. At a high dosage, leucine activates the mammalian target of rapamycin within the muscles which enhances gain of lean tissue. Leucine supplements are currently inaccessible to populations affected by moderate wasting in Kenya. The objective of this study was,therefore,to formulate a leucine-rich composite flour (TheraPEM) from locally available foods for treatment of moderate wasting. Six composite flours were prepared using combinations of beans (Phaseolus vulgaris), groundnuts (Voandzeia subterranea), and foxtail millet (Setaria italica) selected for their high leucine content, local availability and relatively low cost. Nutrient composition analysis and sensory evaluation were conducted on each of the six flours. The three preferred flours in terms of sensory attributes were subjected to accelerated shelf-life evaluation to determine changes in peroxide value, fat acidity, moisture content and total viable count. Kraft paper, gunny bags and plastic containers were the packaging materials used.All six flours met the Codex Alimentarius food standards for minimum energy density (80 kcal/100g) and maximum fat content (27 %) in processed cereal-based foods used for complementary feeding of infants and young children. They all also met the required > 1050 mg leucine per 100 grams of flour. Formulations 2, 3 and 5 had the most preferred sensory attributes and were thus subjected to accelerated shelf-life evaluation. At the fifth month, fat acidity was least in the flours packaged in plastic containers. There was no peroxide formation in any of the three samples during the storage period. The study generated six formulations that meet the minimum requirement for leucine in treatment of moderate wasting but formulation 3, had the most preferred sensory attributes. It is recommended that formulation three be subjected to a study to further validate its effectiveness in the treatment of moderate wasting prior to release for up-scaled use.

Industrial Level

Ricotta fresca cheese is the product of Sardinian dairy industry most exposed to microbial post-process contamination. Due to its technological characteristics, intrinsic parameters, pH (6.10-6.80) and water activity (0.974-0.991), it represents an excellent substrate for the growth of spoilage and pathogenic microorganisms, which are usually resident in cheese-making plants environments. Generally, ricotta fresca has a shelf life of 5-7 days. For this reason, at industrial level, modified atmosphere packaging (MAP) is used to extend the durability of the product. However, few investigations have been conducted to validate the use of MAP in ricotta fresca. The aim of this work is to evaluate the shelf life of ricotta fresca under MAP. A total of 108 samples were collected from three Sardinian industrial cheese-making plants and analysed within 24 h after packaging and after 7, 14 and 21 days of refrigerated storage. Aerobic mesophilic bacteria, mesophilic and thermophilic cocci and lactobacilli, Enterobacteriaceae and E. coli, L. monocytogenes, Pseudomonas spp., Bacillus cereus, yeasts and moulds, and the chemicalphysical parameters and composition of the product were determined. At the end of the shelf life, Pseudomonas spp. and Enterobacteriaceae reached high concentrations, 5 to 7 and 3 to 6 log10 colony forming unit g–1, respectively. The presence of environmental contaminants indicates that the use of MAP without the appropriate implementation of prerequisite programmes is not sufficient to extend the durability of ricotta fresca. Gas mixture and packaging material should be selected only on the basis of scientific evidence of their effectiveness.

Quality And Shelf Life

This study was implemented to assess the mechanism by which Moringa oleifera leaf extract (MOLE) improves the quality and prolongs shelf-life of the broilers’ breast meat. Ninety Cobb chicks were randomly allocated to 3 groups. A control group received the standard diet, whereas the other two groups received diets containing MOLE at the doses of 250 and 500 mg/kg for 21 days. Inclusion of MOLE in broilers diet significantly reduced the detrimental changes in the overall sensory attribute scores, characteristic color and odor, and the loss of breast muscle elasticity during storage. Furthermore, it significantly reduced concentrations of thiobarbituric acid, total volatile nitrogen, non-esterified fatty acids, and peroxide, during storage compared to the control samples. No effect on the concentrations of heavy metals, such as copper, cadmium, and lead, was observed. Decomposition of samples was delayed as indicated by lower pH values and higher sensory scores at 4 and 6 days of storage in the MOLE groups. Reduced contamination with E. coli and Salmonella species indicated an antibacterial effect of MOLE. Finally, the present study highlights that MOLE supplementation may play a role in improving quality and shelf-life of the chilled breast meat in broilers.
