  • Bioactive Peptides by in vitro Digestion of Germinated Bean Cotyledons

    • Authors: Lidia Lopez-Barrios, Erick Heredia-Olea, Daniel Guajardo-Flores, Esther Perez-Carrillo, Janet A Gutiérrez Uribe
      First page: 76
      Abstract: Germinated black bean cotyledons were extruded at two different screw speeds (350 or 400 rpm). Extrudates were digested with pepsin and pancreatin to evaluate the antioxidant and anti-inflammatory activities of hydrolysates collected at 0, 60, 90, 120 and, 180 min. Soluble protein recovered before the enzymatic digestion of extrudates obtained at 350 rpm (E1), or 400 rpm (E2) showed the highest antioxidant (AOX) capacity, with 2,790 or 2,335 µmol eq Trolox/g, respectively and the best nitrogen oxide inhibitory. Even though extrudates presented different peptides profiles, the enzymatic digestion of the storage proteins released similar peptides. RLL and YAL were among the identified peptides obtained after 180 min of enzymatic digestion. Extrusion can be a useful process to produce novel functional ingredients from legume proteins for the food industry.

      Abstract: Uganda is one of the major cassava producing countries in the world. Currently, utilization of cassava is limited to semi-processed products through the informal sector. Cassava has technological potential as a raw material for agro-industrial products, such as flours for baked products, animal feeds and starch. The aim of this study was to investigate the chemical composition of five major cassava varieties grown in Nebbi distict (Uganda), to assess their potential as industrial raw materials. Analysis of the chemical composition of local (Nyamatia and Nyarukeca) and improved (NASE 3, NASE 14, and NASE 19) cassava varieties was carried out using standard methods. Results showed significant (p < 0.05) differences between the varieties indicating high levels of starch, calcium, magnesium, cyanonenic glucosides and phytates. The cassava varieties contain low levels of protein, lipids and minerals with respect to recommended daily intake of these nutrients. Moisture contents ranged from 5.43 for Nyamatia to 10.87 for NASE 19; ash from 1.05 for Nyamatia to 2.39 for NASE 14; crude fiber from 1.06 for Nyamatia to 1.18 for NASE 19; crude protein from 0.74 for Nyarukeca to 1.51 for NASE 14; crude lipid from 0.39 for Nyamatia to 0.63 for NASE 19; and starch contents from 66.72 for NASE 19 to 84.42 for NASE 3. The mineral contents (mg/kg): calcium ranged from 13.15 for Nyamatia to 16.56 for NASE 3; iron ranged from 0.002 for Nyarukeca to 0.01 for NASE 19; zinc ranged from 0.56 for Nyamatia to 0.87 for NASE 3; magnesium ranged from 3.58 for NASE 19 to 3.88 for Nyarukeca; and copper ranged from 0.002 for Nyamatia to 0.14 for NASE 3. The contents of anti-nutrients (mg/kg): cyanogenic glucosides ranged from 30 in NASE 3 and NASE 19 to 800 in Nyamatia; phytates ranged from 661.33 in Nyarukeca to 984.64 in NASE 3; oxalates ranged from 90.6 in Nyarukeca to 227.8 in NASE 3; and tannin ranged from 0.18 in Nyarukeca to 0.33 in NASE 3. Based on the chemical composition results, all the cassava varieties studied contain higher levels of cyanogenic glucosides than recommended by Ugandan and East African Standards, making them unsafe for direct utilization as food and food raw materials for industries at levels beyond 30% in food formulations. The high starch levels in all the cassava varieties make them valuable raw materials for starch and starch-related industries.

      Abstract: The pathogenesis of alcoholic liver diseases progresses from fatty liver to hepatic inflammation and necrosis to fibrosis. Clove buds (Syzygium aromaticum L.) are one of the richest sources of dietary polyphenols with many traditional medicinal uses. Hence, the present work attempted to evaluate the hepatoprotective activity of a standardized polyphenol-rich extract of clove buds (Clovinol). The experiment was conducted on Wistar rats designated into three groups. First group was vehicle control and hepatotoxicity was induced to the second group by the administration of ethanol at the fixed dose of 12.5 g/kg body wt., orally for 30 days. Clovinol (100 mg/kg body wt.) was co-administered with ethanol in the third group. The liver toxicity was assessed by the estimation of liver marker enzymes in addition to which, assays of antioxidant enzymes, inflammatory markers, and liver histopathology studies were also conducted. Ethanol treatment significantly increased (p<0.05) liver function markers (SGOT and SGPT) and reduced (p<0.05) the antioxidant enzymes (SOD, CAT, and GPx) and GSH. It also increased the WBC count, inflammatory markers (nitrite, CRP, COX-2, IL-6 and TNF-α) and lipid peroxidation, significantly (p<0.05). Supplementation of Clovinol showed significant (p<0.05) reversal of all these biochemical and molecular variables indicating the efficacy of Clovinol in the downregulation of alcohol-induced oxidative stress and inflammatory changes, bringing about a significant reduction in the associated liver pathology. To summarize, we found that Clovinol could be a potential functional ingredient for liver health.

      Abstract: Edible insects are widely consumed in different parts of the world and can serve as an alternative nutritional source to conventional foods. Nonetheless, little attention has been given to their quality and shelf life in different packages when exposed to different storage environments. In this study, the effect of storage temperature, duration and type of packaging on the storage stability of the adult house cricket meal was examined. The samples were boiled, solar dried, milled and packaged into polypropylene (PP), plastic (PL) and polyethylene (PL) packages. The samples were then stored for six months in refrigerated and ambient conditions where by changes in physical and biochemical attributes were monitored. Iodine values significantly decreased in all the packages while peroxide, p-anisidine and saponification values significantly increased. SFA, MUFA and PUFA contents reduced during storage although a higher tendency for MUFA and PUFA values was observed in the refrigerated samples. Total viable count (TVC) and yeast and molds counts significantly increased in storage. Three types of fungi; Aspergillus spp., Alternaria spp. and Penicillium spp. were isolated in all the packages. Overall color change steadily decreased with increase in storage time. Deterioration was higher in samples stored in ambient conditions than in refrigeration. The degree of deterioration in the two storage environments among the different packages was in the order; PP>PE>PL. Although the PL package outperformed the other packages it is recommended to carry out sensory analysis and avoid post-processing contamination that can adversely affect the product quality and safety during storage.

      Abstract: The aim of the present study was the implementation of molecular techniques in the detection and quantification of allergic substances of peanut in various kinds of food products, e.g., breakfast cereals, chocolates and biscuits that are frequently related to allergies. In some cases, the presence of peanuts can be due to contamination during production and are not declared on the label. A total of 152 samples were collected from supermarkets and were analysed by a Real Time PCR method. The results indicated that 125 samples (83,3%) were found positive in peanut traces but the most important finding is that from the 84 samples that had no allergen declaration for peanuts, 48 (57,1%) of them were found positive. In conclusion, Real Time PCR can be a very important tool for the rapid detection and quantification of food allergens.

  • Antioxidant Activity of a Oryzanols Concentrate by Differential Scanning

    • Authors: Bruno Irigaray, Ivan Jachmanian, Maria A. Grompone
      First page: 38
      Abstract: Oryzanols are natural antioxidants that are found in appreciable amounts in rice bran oil. However, by chemically refining the crude rice bran oil they are lost during the chemical neutralization step leaving the oil refined with very little oryzanols. The chemical neutralization leaves a residue called "soapstocks" where most of these antioxidants are found. From the soapstocks and by relatively simple procedures it is possible to obtain a oryzanols concentrate which may contain 33% of them. However, its antioxidant power has been little studied in oils compared to other natural antioxidants. Therefore, the present work gives information about the antioxidant power of a concentrate of oryzanols compared to natural antioxidants such as tocopherol and synthetic antioxidants such as butylhydroxytoluene (BHT) added in oils with different degrees of unsaturation and without antioxidants. The results determined by the differential scanning calorimetry method show that the antioxidant power was variable according to the method used. The tocopherol protected the oils from the oxidation at 130°C (soybean and high oleic sunflower) better than the oryzanols concentrate by the isothermal method. When the non-isothermal method was used it was found that the-tocopherol protected soybean oil better than oleic high sunflower oil compared to the oryzanols concentrate. However, when comparing BHT with oryzanols concentrate, BHT generally had a lower protection in both oils and both methods. These results show that the oryzanols concentrate has a protective effect of the oxidation of the studied oils, however, this could depend on the degree of the oil unsaturation.

  • Effect of Surface Coatings on the Shelf life and Quality of Cassava

    • Authors: Loreto Atieno Oduor, Willis Owino, Elijah M. Ateka, Jane Ambuko
      First page: 46
      Abstract: Cassava (Manihot esculenta) is grown as an important dietary source of carbohydrates for communities in a number of African countries. However, Cassava is susceptible to postharvest physiological deterioration which affects its quality and leads to the unpalatability and unmarketability of roots after harvest. Edible surface coatings have been found to be effective in preserving the quality of various perishable food products. This study was undertaken with the objective of determining the best combinations and concentrations of both xanthan gum and guar gum capable as a technology for extending the shelf life of harvested cassava roots. Cassava (variety KME 1) was harvested at physiological maturity. The coating formulations used were: 1%, 1.5%, 2% guar gum, 1.5%, 2%, 2.5% xanthan gum, and 1%, 1.5%, and 2.5% xanthan guar/gum combination in the ratio of 1:1 with some roots left as control. Sampling was done at 2-day intervals for 20 days. The coated cassava showed lower respiration and ethylene production rates than the control samples while change in quality parameters; phenols, colour, flesh firmness, weight loss and dry matter content was significantly (P≤0.05) delayed in the coated samples. The results suggested that using 1.5% xanthan guar/gum as an edible coating, cassava shelf life can be extended by upto 20 days at 25 °C.

    • Authors: Nafiseh Yavari, Mahnaz Mazaheri-Assadi, Ziauddin H. Mazhari, Mohammad B. Moghadam, Kambiz Larijani
      First page: 61
      Abstract: This study is the first report using tea fungus “kombucha” to ferment natural pomegranate juice to produce a fermented beverage with high content of glucuronic acid, as a human health beneficial component. We profited the acetic acid bacteria and yeasts symbiotic layer, which is well known in producing pharmaceutical beverages with considerable released organic acids such as glucuronic acid. Also, we used the natural pomegranate juice with high amount of carbohydrate and acid, as a favourable substrate for the fermentation process. The yield of glucuronic acid production was monitored by cultivating natural pomegranate juices under the 17 optimized-combinations of three distinct sucrose concentrations, fermentation temperatures, and processing time. The combinations were designated by applying the statistical response surface methodology method. The maximum amount of glucuronic acid 17.074g/l determined in the media with 8g/l supplementary sucrose after 14 days fermentation at 37°C, using high-performance liquid chromatography. Along with glucuronic acid production, effect of the three factors - sugar concentration, processing temperature and time - was also examined on changes of five physical and chemical properties of the fermented pomegranate juices, including; pH value, remained sucrose and reducing sugar content, kombucha layer biomass, and total acidity. Within 14-day fermentation process, the pH values showed decrease, the layers’ mass presented considerable increase, and the total acid content increased in the beverages. Overall, obtained data suggested that natural pomegranate juice can be a potential candidate for further development as a functional beverage to support the maximum human daily intake of glucuronic acid (45mg for a 70kg adult).
