Abstract: Nowadays adulteration of meat products, especially of ground meat products which form an easy case scenario for implementing adulteration practices due to their structure and texture, emerges a critical issue of raised concern threatening fair trade, food quality and consumers’ health and protection. Food authentication testing is the tool to address this kind of fraud. There is several analytical methodologies applied for meat authentication targeting at different biomarkers and using a variety of analytical techniques. However, the applied methodologies should exhibit suitable performance characteristics such as reliability, sensitivity, reproducibility and availability in order to be fit for purpose. During the last 20 years, amplification tests have emerged as an important diagnostic tool, not only for clinical applications, but also for food quality and safety. It was urgent to develop molecular techniques fast and sensitive. The introduction of new DNA technologies has facilitated the ease and accuracy of of methods for fraud detection. The closed-tube methods of Loop-mediated isothermal amplification (LAMP) and Gold Nanoparticles linked with oligonucleotides used as molecular probes are well known for their robust and highly sensitive and specific amplification of target DNA. Moreover, these techniques are rapid, low-cost diagnostics and available on site. This review provides a comprehensive overview of the molecular methods developed that can be applied for investigating ground meat adul-teration and focuses on the advantages of the rapid closed tube methods that can yield color results interpreted with the naked eye. The application of such time- and cost-effective molecular tools in the food market is proposed to provide a first-level filter for meat adulterated products, serving as a complementary tool to the more in-depth -omics approach.

Abstract: Commercial retrograded resistant starch (RS3) has been successfully produced from cereals and tubers such as corn and tapioca. Pulse starches have the potential to be utilized as a raw material to make RS3 products due to their high amylose content. However, this opportunity has not yet been explored. In this study, RS3 was produced using pinto bean starch, corn starch, tapioca flour, and rice flour. This was accomplished by gelatinizing the starches, followed by refrigeration for 4 days to allow for retrogradation. Afterwards, the retrograded starch was digested with α-amylase to remove soluble starch, and the remaining non-soluble (high-RS) residue collected, dried, and milled to a flour. Pinto bean starch produced a high-RS product containing 52.88% RS. This amount was not significantly different from what was produced from corn starch (49.54%) and tapioca flour (46.08) %. Rice flour produced the lowest percentage RS (10.33%). The findings demonstrated that pinto bean starch can be utilized as a raw material to produce a high-RS product with comparable resistant starch content to corn and tapioca RS3 ingredients.

Abstract: Chayote (Sechium edule L) has a short shelf life due to its high moisture content (87-95%). This study aimed at prolonging the shelf life of chayote by using different drying methods: convective hot oven drying (OV), and osmo-dehydration (OD) with salt or sugar. Dried samples (at 20% moisture content) were analysed for their nutritional, rehydration, textural and sensory properties. Dried chayote was stored for three months while determining total plate count (TPC), coliforms, Staphylococcus, yeasts and moulds and sensory acceptability. The time to attain 20% moisture in chayote varied significantly (p < 0.05) from 9 h (OV and OD sugar) and 12h for osmo-dried chayote in salt. Ash, total sugar, starch and fiber increased significantly (p ˂ 0.05) from fresh sample as follows 5.2 - 28.3 g/100g (OD salt), 5.8 - 18.5 g/100g (OD sugar), 18.4 - 21.3 g/100g (OD sugar), 49.1 - 52.9 g/100g (OD sugar), respectively after drying. Vitamin C decreased from 232.5 - 38.4 mg/100g (OV) whereas zinc decreased from 1442.9 - 29.5 mg/100g (OV). Rehydration ratio varied from 2.0 ± 0.26 (OD salt after 30 min) to 2.9 ± 0.05 (OV after 20 min). Osmotically dehydrated samples were softer than air dried samples after rehydration and cooking. Total plate counts decreased from log 5.14 to non-detected. Staphylococcus aureus counts decreased from log 4.29 to non-detected. Coliform counts deceased from log 4.91 non detected respectively. Osmotic dehydration contributed to the preservation of the nutritional, textural and sensory properties of dried chayote with salt achieving better preservation than sugar. Drying increased the shelf life of chayote from days to three months with high microbial quality and sensory acceptability. PubDate: Sat, 30 Sep 2023 01:38:57 +000
Abstract: Proper complementary feeding is required to provide essential nutrients to growing infants. However, most families in developing countries are severely food insecure, leading to constant child malnutrition. This study developed fermented corn complementary foods (pap) supplemented with abundantly available and affordable stinging nettles. Stinging nettle leaf flour was incorporated into pap at 5%, 10%, 15% and 20% and evaluated in relation to nutritional, functional, and sensory properties. Soybeans were used to compare the nutritional and health benefits of nettles in infant nutrition. A gradual incorporation of nettle leaf flour increased (p PubDate: Wed, 27 Sep 2023 01:55:29 +000
Abstract: The aim of the study was to investigate the differences in aroma in the many plant-based hamburger analogues in the market today when compared with traditional beef hamburger. For that purpose, we investigated the aroma components using headspace gas chromatography-olfactometry and gas chromatography coupled to mass spectrometry analytical methods. The lipid-derived aldehydes and Maillard reaction compounds were key contributors to the characteristic aroma of a beef hamburger. And that most of the plant-based burgers in the market today were unable to replicate that profile. The plant-based meat analogues displayed a more roasted odor character with higher pyrazine levels and then many show evidence to the addition of other flavor compounds and spices to give the perception of a flavored meat analogue. These approaches resulted in higher flavor intensity; however, the result was something very sensorially different than the sweet, juicy, buttery, and meaty character of beef hamburger. Based on these findings, replication of the characteristic aroma of beef hamburger is complex. This work provides new insights into the key aroma contributors of beef hamburgers and the challenges that exist in trying to replicate it with plant-based meat analogues.

Abstract: Pulse starches are known to have a low glycemic index due to their unique starch conformation and high amylose content. Hence, pinto bean starch (PBS) was extracted from pinto beans and added to bread formulations at 0% (control), 5%, 10%, and 15% concentrations. Texture profile analysis (TPA) on the loaves was completed 24 hours after baking. Following TPA, the breads were analyzed to determine their starch hydrolysis profiles and expected glycemic index (eGI). TPA results showed that inclusion of native PBS in bread did not significantly alter textural characteristics (hardness, springiness, and chewiness), except for cohesiveness which was significantly lower in the bread loaves containing PBS (0.52 – 0.54) compared to the control (0.61). The addition of native PBS (eGI = 37.5) significantly reduced eGI in bread loaves by approximately 2%. However, the final eGI was still within the range considered to be high GI (>70). The findings demonstrated that pinto bean starch may be added to bread to reduce eGI without significantly altering textural properties. PubDate: Fri, 15 Sep 2023 01:30:22 +000
Abstract: Fish is a vital source of animal protein and micronutrients for many communities (rural and urban). It could be the cause of serious Toxi-infection with health consequences if handled in unsanitary conditions. The goal of this study aims to assess the hygienic and microbiological quality of dried fish and smoked fish sold in the various markets in the town of Abéché. A total of 30 samples of dried and smoked fish were collected from the vendors surveyed. Germs sought were counted in the laboratory according to the standard method of microbiology. There most of the respondents are female with 96.67%; 93.33% of them are married. The average age of respondents is between 26 and 35 and more than half (56.57%) are uneducated. The average load of dried fish in the three markets is 4.60 X 107 CFU/g for FAMT; 7.33 X 105 CFU/g for CT; 2.87 X 104 CFU/g for CTT; 1 CFU/g for Staphylococcus aureus. On the other hand, for smoked fish, the average varies between 6.81 X 107 CFU/g for FAMT; 2.28 X 106 CFU/g for CT; 1.56 X 105 CFU/g for CTT and 1 CFU/g for yeasts and molds. Enumeration of staphylococci in the three (3) samples gave high values in the range of 14 to 90 CFU/g. Additionally, the level of contamination by total mesophilic aerobic flora is 74.67% for dried fish and 36.33% for smoked fish. Therefore, it is necessary to follow up when fish processing to reduce the level of contamination by flora microbial. PubDate: Wed, 06 Sep 2023 01:39:31 +000
