Abstract Freshly harvested pumpkin seed was processed into flour namely; raw (RPSF), fermented (FPSF), germinated (GPSF) and roasted (ROPSF). Various pumpkin seed flour obtained were investigated for nutritional properties using standard methods. Protein was higher in the fermented flour (35.85%) while the roasted flour (46.31%) possessed the highest fat content. Results obtained from processed pumpkin seed flour further revealed that glutamic acid (10.45-13.02 g/100g) and linoleic acid (134.72-419.70 µg/ml) were the most abundant amino acid and fatty acid, respectively. Processed pumpkin seed flour contained appreciable amount of minerals and demonstrated very good functional properties. It can be concluded that subjecting pumpkin seed to various processing methods enhanced its nutritional properties and may find application in food industry.

The aim of the study was determined the suitability of Cucurbita pepo L. (pumpkin) seed flour (PSF) supplement, which is limited for use in the food industry, to increase some chemical and functional properties of crackers.  PSFs were used to replace wheat flour in cracker formulation at the levels of 5, 10, 20 and 30%. Particularly, the total dietary fiber, protein and ash content of crackers with PSF increased. The highest increase in mineral contents of crackers were determined in P> K> Mg> Ca> Zn> Fe> Cu. The predominant organic acid of crackers was tartaric acid and the dominant fatty acid was linoleic acid. Crackers prepared with Nevşehir variety PSF yielded better results than other crackers due to their nutritious properties. As a result, with the addition of PSF, a functional food product with health benefits was obtained and a contribution was made to the product range.

The possible combination of cowpea with moringa seed flour for the production of nutrient dense moimoi (steamed cowpea paste) and akara (deep-fat fried balls) were investigated. Composite blends of cowpea and moringa seed flour in different proportions (98:2, 96:4 and 94:6) were used in moimoi and akara production while 100% cowpea flour served as control. The proximate and sensory analyses of the products were determined using standard methods. The results showed a positive influence in the proximate compositions of these products as the proportion of moringa seed flour substitution increased. The moimoi samples ranged between 10.77 – 26.92%, 18.27 – 21.16%, 8.12 – 10.72%, 1.80 – 2.19%, 0.76 – 0.84%, 44.07 – 53.99% and 269.87 – 335.18 Kcal/100g while akara samples ranged between 9.73 – 10.77%, 19.51 – 22.12%, 7.41 – 9.90%, 2.39 – 2.71%, 0.87 – 0.93%, 54.69 – 59.00% and 320.26 – 332.08 Kcal/100g respectively for moisture contents, protein contents, crude fats, ash, crude fibers, carbohydrates and energy values. The sensory evaluation results of these products favourably competed with the control except samples D (94:6) which showed a slight difference in all parameters tested. Thus, the substitution of cowpea with moringa seed flour up to 2% and 4% proportions are adequate to produce acceptable moimoi and akara, respectively.The possible combination of cowpea with moringa seed flour for the production of nutrient dense moimoi (steamed cowpea paste) and akara (deep-fat fried balls) were investigated.

BACKGROUND: Serum zinc levels are found to be low in children of protein energy malnutrition globally. Pumpkin seed flour has a high zinc content of 6.88 mg/100 g, has been formulated biscuits made from pumpkin seed flour with a zinc content of 1.52 mg/100 g. AIM: This study aims to determine the effect of giving biscuits made from pumpkin seed flour to serum zinc levels and body weight in malnutrition Wistar rats. METHODS: This research is a true experiment with pre-post-test with control group design. Subjects were 28 male Wistar strain rats induced by fasting malnutrition for 3 days and then given biscuits with a zinc dose of 0.027 mg; 0.054 mg; and 0.081 mg/BW/day and in the control group without biscuits for 2 weeks. Serum zinc levels were examined using the atomic absorption spectrophotometry method. Data were analyzed using paired t-test and one-way ANOVA test. RESULTS: Paired t-test results on serum zinc levels obtained p > 0.05 and on body weight obtained p < 0.05. One-way ANOVA test results on serum zinc levels after the intervention obtained p > 0.05 and at body weight obtained p < 0.05 followed by post hoc least significant difference test found that there were significant differences between the control group and the P1 group, a dose of 0.027 mg (p = 0.015) and P2 groups, doses of 0.054 mg (p = 0.012). Greater weight gain was found in the P1 group with an increase of 38.85%. CONCLUSION: The provision of biscuits made from pumpkin seed flour has an effect on increasing body weight of malnutrition Wistar rats and has no effect on serum zinc levels, so further research is expected to use different doses.

In this study, fortified pasta was prepared by replacing semolina with 0, 5, and 10 g/100 g of grape pomace (GP), a food industry by-product, rich in fiber and phenols. GP inclusion in pasta significantly reduced its optimum cooking time and the swelling index, while also increasing the cooking loss (p < 0.05). Furthermore, pasta firmness and adhesiveness were enhanced by the GP addition, as well as the total phenol content and the antioxidant activity, evaluated through ABTS and FRAP assays (p < 0.05). From a nutritional point of view, increasing amounts of GP resulted in a significative decrease in the rapidly digestible starch and an increase in the slowly digestible starch, while the predicted in vitro glycemic index was also reduced (p < 0.05). Sensory analysis showed that fortified spaghetti had good overall acceptability, and the results suggest that GP-fortified pasta could represent a healthy product with good technological and sensory properties.

Antioxidants are a wide group of chemical compounds characterized by high bioactivity. They affect human health by inhibiting the activity of reactive oxygen species. Thus, they limit their harmful effect and reduce the risk of many diseases, including cardiovascular diseases, cancers, and neurodegenerative diseases. Antioxidants are also widely used in the food industry. They prevent the occurrence of unfavourable changes in food products during storage. They inhibit fat oxidation and limit the loss of colour. For this reason, they are often added to meat products. Many diet components exhibit an antioxidative activity. A high antioxidative capacity is attributed to fruit, vegetables, spices, herbs, tea, and red wine. So far, the antioxidative properties of various plant materials have been tested. However, the antioxidative activity of some products has not been thoroughly investigated yet. To date, there have been only a few studies on the antioxidative activity of the pumpkin, including pumpkin seeds, flowers, and leaves, but not the pulp. The main focus of our experiment was to optimize the extraction so as to increase the antioxidative activity of the pumpkin pulp. Variable extraction conditions were used for this purpose, i.e., the type and concentration of the solvent, as well as the time and temperature of the process. In addition, the experiment involved a comparative analysis of the antioxidative potential of 14 pumpkin cultivars of the Cucurbita maxima species. The study showed considerable diversification of the antioxidative activity of different pumpkin cultivars.

Lonicera caerulea L. (haskap) berries are widely known for their richness in anthocyanins. In this study, such fruits were assessed for their nutritional and chemical composition, but also as sources of anthocyanins with great colouring properties to be applied in foodstuff. Haskap presented high levels of water, four free sugars (mainly fructose and glucose), five organic acids (mainly citric, malic, and quinic), α- and γ-tocopherol, twenty fatty acids (with prevalence of linoleic acid), and eight phenolic compounds, among which six were anthocyanins (mainly cyanidin-3-O-glucoside). The extract presented great antioxidant properties, evaluated through TBARS and OxHLIA assays, as well as antimicrobial capacity against six bacteria and six fungi. Two colourants were obtained by spray-drying haskap juice with maltodextrin and a mixture of maltodextrin and arabic gum. These formulations were stable over 12 weeks of storage at room and refrigerated temperature, without significant variations in colour parameters and in anthocyanins concentration. They were considered safe for consumption once neither microbial contamination nor cytotoxicity in non-tumour cells were detected. The results obtained allow for the consideration of haskap as a promising source of colourants to be applied not only in the food industry, but also in other fields that rely on artificial colourants.

Bioactive compounds are significant to human nutrition. They are beneficial to health as they inhibit the development of numerous diseases of affluence. Scientists continuously search for natural sources of these components. At present, the chemical composition of various plants is under investigation. Many researchers are interested in pumpkin (Cucurbita L. spp.). Different organs of this plant (pulp, seeds, flowers, leaves, shoots, roots) are consumed almost all over the world. They contain large amounts of bioactive compounds. Pumpkin pulp is used to prepare various dishes. It is also widely used in the food industry for the production of pastries, baked goods, juices, jams, marinades, and baby food. The content of carotenoids in the pumpkin has been documented in a large number of publications. However, so far there has been no complex analysis of the profile of other bioactive compounds. This article analyses 11 pumpkin cultivars of the Cucurbita maxima Duchesne species. It compares the chemical composition of the pulp and analyses the content of bioactive compounds such as carotenoids, polyphenols (flavonols and phenolic acids), tocopherols, minerals (K, Ca, Mg, Na, Fe, Zn, Cu, Mn), vitamins (C, B1, folates). In view of available information, the study provides an innovative approach. The analysis showed high diversity in the concentration of individual components between the cultivars. The research proved that pumpkin pulp was not only a source of carotenoids but also other bioactive compounds.
