Use of honey is gaining ground worldwide as people are getting aware of the high nutritional values and beneficial health promoting effects of honey. This study was carried out in order to compare the proximate compositions and the mineral contents available in both natural honey and artificial honey obtained from some selected towns in Ijebu and Remo zones of Ogun State, Nigeria. The parameters were analyzed using standard methods of Association of Official Analytical Chemists (AOAC, 2005). From the results obtained, the proximate compositions (%) of the natural honey were - moisture content (17.85±0.74), carbohydrate (78.56±2.92), protein (2.43±0.23), fat (0.68±0.04), crude fiber (0.19±0.02), ash (0.29±0.05) while that of the artificial honey were moisture content (21.65±0.94), carbohydrate (76.25±2.67), protein (1.53±0.12), fat (0.30±0.07), crude fiber (0.12±0.01), ash (0.15±0.09). The natural honey compositions were generally better than those of the artificial honey compositions. This trend was also observed for the mineral contents – Na, K, Ca, Mg, Fe, Zn and other parameters such as pH, titratable acidity, electrical conductivity and total acidity analyzed.

The quest for cheap and quality food is on the increase, especially during economy crises. Some nutritional properties of the raw and cooked local and industrial spaghetti were determined using standard methods. Concentrations of mineral elements were determined using atomic absorption spectrophotometer. Total ash (0.98±007 %), crude protein (14.28±0.15 %) and carbohydrate (77.95±0.11 %) levels in the raw industrial spaghetti were higher compared to the locally processed raw spaghetti. Carbohydrate and moisture levels for both processed spaghetti increased on cooking, while total ash and protein contents decreased. Crude fiber (0.009±0.00 %), carbohydrate (77.52±0.21 %) and moisture levels in the cooked local spaghetti were higher than in the cooked industrial spaghetti. Proximate contents of the local and industrial raw spaghetti were significantly (P ≤ 0.05) different. Concentrations of mineral elements in the raw locally processed spaghetti were lower than in the industrial spaghetti. Low levels of functional properties were recorded in the local spaghetti. Cooking decreased zinc content in the spaghetti, but significantly (P ≤ 0.05) increased the moisture content, crude fiber, carbohydrate and mineral contents. The spaghetti processed locally may serve as an alternative to the industrial spaghetti.

The proximate and some essential mineral compositions of groundnuts processed by different methods for consumption were determined. The parameters were analyzed using standard methods of the Association of Official Analytical Chemists (AOAC, 2005) and Greenfield and Southgate, 2003. From the results obtained, it was found that the proximate compositions (%) of the groundnuts boiled with the pods were – moisture content (18.77  0.02), crude protein (22.93  0.06), crude fat (38.94  0.03), crude fiber (1.75  0.02), ash (3.90  0.04) and carbohydrate (13.73  0.04). Groundnuts roasted with the pods had– moisture content (2.91  0.04), crude protein (29.73 0.08), crude fat (50.11  0.04), crude fiber (4.36  0.03), ash (5.14  0.03) and carbohydrate (7.76  0.05) while those of the groundnuts roasted without pods were – moisture content (2.88  0.04), crude protein (26.64  0.06), crude fat ss(49.04  0.02), crude fiber (4.26  0.03), ash (4.73  0.02) and the carbohydrate (11.50  0.04). The mineral compositions (in (mg/kg) of the groundnut sample boiled with pods were Na (0.23), K (0.67), Ca (0.11), P (0.38), Mg (0.16) and Fe (41.5). Groundnut samples roasted with the pods were Na (0.38), K (0.98), Ca (0.17), P (0.47), Mg (0.27) and Fe (61.2), while the mineral compositions (in (mg/kg) of the groundnut samples roasted without the pods were Na (0.27), K (0.82), Ca (0.16), P (0.42), Mg (0.25) and Fe (53.6). This study revealed that the proximate and the mineral contents in the roasted samples were generally higher than those of the boiled sample except for the moisture and the carbohydrate contents.

Objective: Ogi is a fermented cereal gruel produced from maize, sorghum or millet. The objective of the study was to investigate the effect of ginger and cinnamon on the proximate composition and sensory properties of corn ogi. Methodology: Ogi slurry was prepared from corn and fortified with 5% ginger, 5% cinnamon, 5% ginger: 5% cinnamon and 2.5% ginger: 2.5% cinnamon spices and 100% corn ogi as control. The samples were analyzed for proximate composition and sensory properties using standard methods. Results: The results obtained from this study indicated that there was an increase in the moisture, ash, protein and fat contents of corn ogi spiced with ginger and cinnamon and a decrease in carbohydrate content. These increases were observed to be significant (p<0.05) with corn ogi samples spiced with ginger than for cinnamon except for crude fiber which was higher in ogi spiced with cinnamon. Moisture content of the ogi samples ranged from 8.53-9.79%, crude protein 5.13-6.37%, ash 0.19-0.30%, crude fiber 0.29-0.81%, carbohydrate 78.93-81.64% and energy contents 387.77-391.98 kcal. The inclusion of cinnamon and ginger had no significant (p<0.05) effect on the sensory properties of the unsweetened spiced ogi samples. Mean scores obtained for unsweetened ogi samples were low. Upon sweetening with sugar, these scores were increased for all sensory attributes. Sensory evaluation of sweetened ogi samples showed that the control sample was more preferred for all sensory attributes and this was followed closely by sample ogi spiced with 5% ginger. Conclusion: This study recommends the use of ginger at 5% for the fortification of corn ogi which will result in ogi with sensory properties similar to 100% corn ogi. It also showed the potential of fortifying corn ogi with ginger and cinnamon, either singly or as a blend, to enhance the nutritional quality of corn ogi.

The present study assesses the feasibility of noni and mulberry as a raw substrate for the production of probiotic noni and mulberry juice by lactic acid bacteria (Lactobacillus plantarum SK-3 and Pediococcus acidilactici M-3). Changes in pH, titratable acidity (lactic acid), cell survival, and antioxidant properties were examined during fermentation. Both the strains grew well in noni juice and mulberry juice after 48 hour fermentation. P. acidilactici M-3 produced less lactic acid than L. plantarum SK-3. After 28 days of cold storage, both tested strains survived the low-pH conditions in fermented noni juice and mulberry juice. Both the juices fermented with L. plantarum SK-3 had a high antioxidant capacity. The noni and mulberry juice fermented with L. plantarum SK-3 had shown the cholesterol-lowering ability better than the juices fermented with P. acidilactici M-3. Finally, L. plantarum SK-3 and P. acidilactici M-3 were found as optimal probiotics for fermentation with noni juice as well as mulberry juice. In this investigation, the results could be an indicator of the development of health-promoting food juices.

The cracking of sweet cherries causes significant crop losses. Sweet cherries (cv. Bing) were coated by electro-spraying with an edible nanoemulsion (NE) of alginate and soybean oil with or without a CaCl2 cross-linker to reduce cracking. Coated sweet cherries were stored at 4 °C for 28 d. The barrier and fruit quality properties and nutritional values of the coated cherries were evaluated and compared with those of uncoated sweet cherries. Sweet cherries coated with NE + CaCl2 increased cracking tolerance by 53% and increased firmness. However, coated sweet cherries exhibited a 10% increase in water loss after 28 d due to decreased resistance to water vapor transfer. Coated sweet cherries showed a higher soluble solid content, titratable acidity, antioxidant capacity, and total soluble phenolic content compared with uncoated sweet cherries. Therefore, the use of the NE + CaCl2 coating on sweet cherries can help reduce cracking and maintain their postharvest quality.

“Soumbara” is a fermented product sold in the markets of several West African countries. In the markets, it is sold in several formats (granulated, powder, and paste). The objective of this study was to evaluate the microbiological and physicochemical characteristics of these three types of “Soumbara” sold in the Korhogo markets. For this purpose, a preliminary survey followed by a sampling of 54 samples of “Soumbara” was carried out. The microorganism load count was carried out according to microbiological standards. The pH, titratable acidity, and moisture content were measured, respectively, with a pH meter, by dosing with sodium hydroxide solution and by differential weighing after passing the sample through the oven. The pH of the different samples is around 6. The moisture content is higher in “Soumbara” paste (20-24.7%) than in powdered (7.3-9.3%) and granulated (8.6-10.7%) “Soumbara.” The acidity rates are between 0.07 and 0.13%, 0.2 and 0.3%, and 0.08 and 0.1%, respectively, for the granulated, powder, and paste types. Mesophilic aerobic germ loads (6.17-8.38 log10 cfu/g) for all three types of “Soumbara” are above the standard. Total coliform (1.13-2.96 log10 cfu/g), mould (0.86-2.52 log10 cfu/g), and yeast (0.33-1.53 log10 cfu/g) loads are below standard. The microbiological quality of the three types of “Soumbara” is unsatisfactory. Overall, “Soumbara” powder is the most contaminated, followed by granulated and paste “Soumbara.” “Soumbara” must be added during culinary preparations in order to avoid possible public health problems.

The amount of titration acid in must is in the largest number of cases with in the range 5.0-8.0 g/dm3. Wines, as a rule, contain less acids than must, and according to Regulations, titratable acidity is in the range of 4.0-8.0 g/dm3 expressed in tartaric acid, because a part of tartaric acid is deposited in the form of salts (tartar or argol) during alcohol fermentation. For wines that contain less than 4 g/dm3 of titratable acids there arises a suspicion about their origin, that is, that during the preparation some illegal acts were done. Because of that, the aim of this paper is to determine titratable acidity in white wine, using standard methods of determination, which are compared with the results received by potentiometric titration using ion-selective electrode. According to the received results it can be seen that wine titration with indicator gives sufficient reliable values of wine titration acidity. However, as potentiometric titration at pH value 7.00 is more reliable and objective method, the values of titratable acids content in wine, expressed through tartaric acid, are given according to this result. The analysis of differential potentiometric curves shows that these curves can give us an answer to the question of the presence of a larger amount of other nonorganic substances, which have already existed in wine. However, none of the used methods gives absolutely reliable answer what substances are present in analysed samples.

Honey as a food has long been used in human nutrition and is still popular. Honey is important because of its therapeutic, prophylactic and strengthening value. Pollen is one of the most decisive components that ensure the quality and type of honey. Modern society becomes more and more sensitive to airborne pollen. Therefore, it is crucial to determine the composition of allergenic plant pollen in natural honey. For this purpose, we studied and compared pollen abundance in honey and air samples collected in Lithuania. Standard methods for pollen investigation in air and honey were used in this study. The botanical diversity of pollen identified in honey and air samples indicates 10 morphotypes: 8 of woody plants and 2 of herbaceous plants, in both the honey and air samples. <em>Salix</em> pollen counts in the honey were found to be highest among airborne pollen from May to September. The anemophilous allergenic pollen constituted 44 % of the total pollen detected in the honey.

Background: Turmeric and red chili are the common spices used for cuisine preparation in Bangladesh. Commercially packed turmeric and red chili might have decreased nutrient contents compared to raw turmeric and red chili. Aims:  The study aimed to compare some of the nutrient values between the commercially packed and raw turmeric and red chili. Methods: Commercially packed turmeric and red chili with different brand names (Radhuni, Tiger and Pran) and in raw turmeric and red chili were purchased from local market. Proximate analyses - dry matter (DM), crude protein (CP), crude fiber (CF) and mineral contents were performed. The total phenolics and total tannin contents were determined using appropriate methods. Results: The proximate analysis results showed that both Radhuni (97.56 mg/g) and Tiger (97.28 mg/g) turmeric revealed significantly higher content of DM (p<0.001). No notable difference was observed in CP value. Crude fiber value displayed significantly highest value (p<0.001) in Tiger brand (4.96 mg/g) and the lowest in Radhuni brand (1.76 mg/g). Mineral content was significantly (p<0.05) highest in raw turmeric (9.97 mg/g). A significantly higher amount (p<0.001) of DM in packed chili was recorded. Tiger chili contained significantly higher amount of CP (6.02 mg/g) and CF (9.31 mg/g) while Radhuni contained the lower amount of CP (4.81 mg/g) and CF (2.48 mg/g). Raw chili had significantly higher amount of ash (13.24 mg/g). Examination revealed significant level (p<0.001) of total phenolics in acetone extracts of Tiger turmeric and chili powder. Significant amount of tannin was found in raw turmeric (33.89 µg/g; p<0.005); however, Pran brand of turmeric had the lowest amount of tannin (9.53 µg/g). Tannin content recorded in red chili was significantly (p<0.001) higher in commercially packed Tiger brand which was 16.57 µg/g compared to raw red chili (3.315 µg/g). Antioxidant analysis showed higher antioxidant activity in both raw turmeric and red chili powder. Conclusion:  Tiger brand turmeric ensures the standard moisture, fiber and protein contents as well as the amount of phenolics and tannin.
