Energy bars are considered a healthy food alternative due to the different properties attributed to them. The research aimed to evaluate the influence of amaranth and melon seeds on the nutritional composition of an energy bar intended for human consumption. A unifactorial design with three treatments T1 (45% amaranth, 15% melon seeds), T2 (30% amaranth, 30% melon seeds), T3 (15% amaranth, 45% melon seeds) was used to prepare the bars. energetic. Proximal analysis of protein, ash, fat, fiber, moisture, carbohydrates, and energy were performed on each of the formulations. A sensory evaluation of each of the treatments was carried out in which the attributes of smell, color, flavor, texture and general appearance were evaluated; A total of 20 untrained panelists were used for this. The results were analyzed with the statistical program InfoStat. The proximal analysis shows that the content of protein, ash and fiber was higher in the T2 treatment with a total of 11.03%, 12.59% and 13.43%, respectively. The fat, moisture and energy contents were higher in the T3 treatment with a total of 13.74%, 5.62% and 3820.85%. While the highest carbohydrate content was presented in treatment T1 with 67.14%. The evaluation of the organoleptic properties of taste, smell, color, texture and general appearance was better in the T3 treatment. The inclusion of the different levels of amaranth flour and melon seeds showed favorable results of the proximal and sensory characteristics (color, smell, flavor, texture and general appearance).

The nutritional composition and productivity of halophytes is strongly related to the biotic/abiotic stress to which these extremophile salt tolerant plants are subjected during their cultivation cycle. In this study, two commercial halophyte species (Inula crithmoides and Mesembryanthemum nodiflorum) were cultivated at six levels of salinity using a soilless cultivation system. In this way, it was possible to understand the response mechanisms of these halophytes to salt stress. The relative productivity decreased from the salinities of 110 and 200 mmol L−1 upwards for I. crithmoides and M. nodiflorum, respectively. Nonetheless, the nutritional profile for human consumption remained balanced. In general, I. crithmoides vitamin (B1 and B6) contents were significantly higher than those of M. nodiflorum. For both species, β-carotene and lutein were induced by salinity, possibly as a response to oxidative stress. Phenolic compounds were more abundant in plants cultivated at lower salinities, while the antioxidant activity increased as a response to salt stress. Sensory characteristics were evaluated by a panel of culinary chefs showing a preference for plants grown at the salt concentration of 350 mmol L−1. In summary, salinity stress was effective in boosting important nutritional components in these species, and the soilless system promotes the sustainable and safe production of halophyte plants for human consumption.

In recent times, the popularity of adding value to under-utilized legumes have increased to enhance their use for human consumption. Acacia seed (AS) is an underutilized legume with over 40 edible species found in Australia. The study aimed to qualitatively characterize the chemical composition of 14 common edible AS species from 27 regions in Australia using mid-infrared (MIR) spectroscopy as a rapid tool. Raw and roasted (180 °C, 5, 7, and 9 min) AS flour were analysed using MIR spectroscopy. The wavenumbers (1045 cm−1, 1641 cm−1, and 2852–2926 cm−1) in the MIR spectra show the main components in the AS samples. Principal component analysis (PCA) of the MIR data displayed the clustering of samples according to species and roasting treatment. However, regional differences within the same AS species have less of an effect on the components, as shown in the PCA plot. Statistical analysis of absorbance at specific wavenumbers showed that roasting significantly (p < 0.05) reduced the compositions of some of the AS species. The results provided a foundation for hypothesizing the compositional similarity and/or differences among AS species before and after roasting.

In Vietnam, the giant mottle eel Anguilla marmorata is the most widely distributed species and being exploited for seed in aquaculture as well as for human consumption. This study aims to investigate the basic nutritional components of the fish. The eels were collected from six locations of Thua Thien Hue province, with weights from 5 to 3200 g. In addition, the content of lipid in skin and tissue was also examined. The results show that eel flesh has a relatively high nutritional value. The water, protein, lipid, and total sugar content of the fish meat is 60.4 ± 0.94%, 19.54 ± 4.31%, 18.2 ± 1.02%, and 1.34 ± 0.34 (mg/g), respectively. The nutritional components of the eel have a good correlation with the weight according to the equation: Y = a × ln (W) + b (where W is the weight of eels; Y is the content of nutritional components; a is the correlation coefficient b is a constant) with r > 0.9. The lipid content of the fish skin is higher than that of muscle and meat.

Fresh tengra fish (Mystus tengara) samples were collected from fish market, Kawardha and different levels of salt and turmeric powder were added (0% salt and 0% turmeric powder, T0; 2% salt with 0.2% turmeric, T1; 4% salt with 0.2% turmeric, T2; 8% salt with 0% turmeric powder, T3 and 12% salt with 0% turmeric powder, T4). The processed and salted fish were dried in hot air oven at 60°C for 20 hours. Carcass yield (%), salt content (%), pH and moisture content of cured fish were respectively 39.06 - 43.87%, 3.15 - 4.59%, 6.52- 6.90 and 4.91 – 6.84 %. The sensory assessment showed that treatment T2 had the highest score for texture 5.70; appearance 8.30, odor 8.02 and taste 8.05 while T0 and T1 had least sensory scores. Aerobic plate count of various treatments were found significantly different (p Lass Than 0.05) with the lowest in treatment T4 (3.3 x 103 cfu/g) followed by treatment T2 (3.7 x 103 cfu/g) and highest in treatment T0 (5.4 x 103 cfu/g). Tengra fish cured with 4% salt and 0.2% turmeric powder (T2) found to be the best in yield, microbial load and sensory attributes. The dry salted fish processed with low level of salt and turmeric powder are best for human consumption, particularly for the patients of blood pressure and diabetes.Therefore, preparation of dried products from low-cost fish will help in increasing the employment opportunities and also reduce post-harvest losses.

<p>The obstacle in developing coconut water-based product is its easily altered properties. Ultrafiltration and ultraviolet processing are potential to obtain a longer shelf life for coconut water drink without altering its nutritional values and unique organoleptic properties, unlike other processing techniques e.g. pasteurization and ultra high temperature. Shelf-life estimation experiment showed that ultrafiltration-and- ultraviolet-processed coconut water without any addition of food additives can be stored for 51 days in 00C. The objective of this research was to evaluate the effects of ultrafiltration and ultraviolet treatments on the nutritional, physicochemical and organoleptic properties of coconut water drink. The experiments were carried out at Food Analysis Laboratory, Indonesian Center of Agricultural Postharvest Research and Development, on January-April 2015. Coconut water was flown through the ultrafiltration membrane unit and ultraviolet light unit, samples were collected in three repetitions. Nutritional composition and physicochemical properties of fresh coconut water (FCW) and coconut water drink obtained from ultrafiltration and ultraviolet process (CUU) were evaluated and compared. Organoleptic analysis was done by 20 panelists, observations included quality hedonic (aroma, sweetness, saltiness, sourness and turbidity), and acceptance (preferance and ranking test), comparing FCW and CUU with commercial coconut water drink (CWD). CUU showed indistinguishable nutritional composition and physicochemical characteristics from FCW (p&gt;0,05), except on total sugar (p=0,049), clarity (p=0,001), L* (lightness) (p=0,000) and b* (yellowish) (p=0,002). Panelists gave CUU a statistically equal rank to FCW, and better than CWD. The organoleptic characteristics of CUU were concluded as relatively same in saltiness and aroma as FCW, and less intense in sweetness and turbidity compared to CWD. After 10 days storage, panelists level of liking was higher for CUU compared to CWD in color (p=0,004) and general appearance (p=0,016).</p><p>Keywords: coconut water, nutritional composition, organoleptic properties ultrafiltration, ultraviolet</p>

Proximal Analysis

The consumption of vegetables in Mexico includes a wide variety of plants that grow naturally as weeds in the fields. The intake of these vegetables is very important in the Mexican diet because these plants supply an important input of nutrients and compounds such as fiber, vitamins, minerals, and antioxidants. Thus, the plants may be universally promoted as healthy. However, there is little information about these vegetables of popular consumption, especially in terms of the nutritional changes caused by boiling. To determine the influence of boiling on five plants of popular consumption in Mexico, the nutritional composition (proximal analysis, dietary fiber, and oxalates), antioxidant compounds (ascorbic acid, phenolics), antioxidant activity (measured by ABTS and DPPH assays), and physicochemical characteristics (water retention capacity, viscosity, color, and SEM) were evaluated. The boiling affected the nutritional composition of plants, mainly soluble compounds as carbohydrates (sugars and soluble fiber), ash, ascorbic acid, and phenolic compounds and caused changes in food hydration and color. Therefore, it is recommended that these plants be consumed raw or with short boiling times and included the cooking water in other preparations to take advantage of the nutrients released in the food matrix. In the future, to complete studies, 3 to 5 min of cooking should be considered to minimize undesirable modifications in terms of the vegetables’ composition.

Energy bars were developed using different levels of potato extrudates (0-30%) with sweeteners (45-55%), rolled oats, puffed rice, defatted soy flour and milk powder. The potato extrudates were prepared by mixing potato paste having moisture content 30% with wheat grits having moisture content 8% in the ratio of 20:80 respectively. The developed energy bars were analyzed for colour, nutritional quality and sensory attributes. Different levels of potato extrudates and sweeteners significantly affected the hua and chroma values of the energy bars. The increasing levels of potato extrudates and sweeteners (specially honey) significantly increased moisture content of energy bar. The protein content was increased significantly with increasing level of potato extrudates but found decreased with increasing level of sweeteners. The energy bar containing 20% potato extrudates and 50% sweeteners was found most sensory acceptable by panel members and it provided 8.38% protein, 2.36% crude fiber, 73.67% carbohydrates and 343.03kcal energy which also stored well at refrigeration condition.

Edible marine gastropods are consumed in northern Patagonia without regulations or knowledge of nutritional composition and food quality. We determined total lipids (TL), fatty acid (FA), paralytic shellfish poison (PSP) and metal contamination in six edible marine gastropods: Buccinanops globulosus, B. cochlidium, Trophon geversianus, Odontocymbiola magellanica, Tegula patagonica and Nacella magellanica. TL was lowest in the foot (0.29–0.56%) and maximum in organs (1.43–3.2%), presenting less TL than other edible species around the world. Saturated FA were similar to other consumed marine gastropods worldwide and dominant in all species studied (33.26–48.19%), while monounsaturated FA reached about 30% only in 2 species, but did not exceed 18% in the other species. Polyunsaturated FA reached up to 23.77%, but generally did not exceed 14%. Highly unsaturated FA (AA, EPA and DHA), reached about 27%. The dominant FA was palmitic acid (0.217 to 2.43 µg mg−1).Differences in FA could be related to the different alimentation of the species. Limit of PSP consumption was exceeded in a few months only for two species. Lead was not detectable (<4 µg g−1) while cadmium ranged from 0.07 to 15.32 µg g−1. Our results can be useful to ensure the safety food of these resources, which are being consumed and exported in low quantities in Argentina, but may be commercialized massively in the near future. Monitoring these and other food resources is essential and should be performed in any established fishery of the species reported here to guarantee the safety human consumption.

Antioxidant activities and nutritional composition are essential ingredients normally considered in the choice of vegetables for human consumption. Leafy vegetables in particular, are regarded as protective foods in human diet due to their many health benefits. The aim of this research was to carry out the quantitative phytochemical screening, the antioxidant activities of extracts and determine the nutritional content of Cucurbita maxima and Vigna unguiculata leaves. Quantitative phytochemical screening were conducted using standard techniques. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays were used to determine antioxidant activities of these extracts. Nutritional composition was determined using standard procedures.  Quantitative analysis revealed the phytochemicals in C. maxima and V. unguiculata as; saponins (1.03%, and 1.34%), tannins (3.49% and 2.60%), terpenoids (0.0% and 0.47%), flavonoids (2.81% and 4.11%), alkaloids (5.72% and 3.5%), phenols (4.02% and 3.83%) respectively. There was a significant (p=0.05) difference in radical scavenging activity of ethanol leaf extract of V. unguiculata comprared to C. maxima. In FRAP both plants’ extract revealed a good antioxidant reducing power at 100mg/ml (range 0.40 to 0.5 absorbance) at 700nM. Antioxidant activities of extracts is attributed to their flavonoid and phenolic contents. Proximate analysis revealed the nutrients for C. maxima and V. unguiculata as; crude protein (11.58% and 14.83%), crude fat (0.47% and 0.61%), ash (4.11% and 3.72%), crude fiber (6.95 and 4.68%), moisture (1.03% and 1.38%), carbohydrate (75.86% and 74.78%) respectively. This shows that the leaves are a good source of energy to both humans and animals. Also, both vegetables revealed good percentages of proteins which can be used to compliment other sources of protein.
