The phytochemical characteristic analysis of a group of 30 haskap berry genotypes was carried out bearing in mind the concern for the consumption of food with high nutraceutical value that helps maintain good health. Phytochemical fruit composition and antioxidant activity were assessed by the Folin–Ciocalteau, spectrophotometric, DPPH (1,1-diphenyl-2-picrylhydrazyl) as well as ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) method. Evaluation of antioxidant activity was referred to as the Trolox equivalent. The observed differences in the content of phenolics, flavonoids, vitamin C and antioxidant activity allowed us to select genotypes which, due to the high level of the analyzed compounds, are particularly recommended in everyone’s diet. In addition, the analysis of the prospects of increasing the analyzed phytochemical properties, estimated by parameters such as heritability and genetic progress, indicates the effectiveness of breeding in relation to each of the analyzed traits. The results of the presented research can be used in the implementation of future breeding programs for this valuable species.

Summary This study aimed to characterize propolis with respect to its antioxidant activity and apply it to the elaboration of Italian-type salami. A propolis sample was collected and subjected to chemical and physicochemical characterization and its antioxidant capacity determined. Four salami formulations were developed: F1 (no antioxidants); F2 (addition of 0.01% BHT); F3 (addition of 0.01% propolis) and F4 (addition of 0.05% propolis). The salamis were evaluated with respect to their physicochemical properties and lipid oxidation. The characterization of the propolis showed a high level of waxes and low levels of phenolic compounds and flavonoids, although in sufficient quantity to prove their antioxidant activity. The Italian-type salamis showed moisture, protein and lipid contents which conformed to the limits preconized by Brazilian legislation. The F4 formulation (0.05% propolis) showed a better result when compared to the formulations F3 (0.01% propolis) and F1 (no antioxidant). However, formulation F2 (0.01% BHT) showed the lowest value of lipid oxidation. The results showed that propolis inhibits oxidative action and can be added to meat products as a natural antioxidant.

The present study aimed to formulate a nutraceutical enriched fruits and nuts spreads and analyze the presence of phytochemicals in the formulated spread. The pumpkin seeds and cucumber seeds were roasted at 150° C for 15 mins and made into powder. The seed powder was mixed to the pulp of ?-carotene rich fruits like mango, papaya and muskmelon in order to make fruits and nuts spread. Treatments like Mango with pumpkin seed powder (T1), Papaya with pumpkin seed powder (T2), Muskmelon with pumpkin seed powder (T3), Mango with cucumber seed powder (T4), Papaya with cucumber seed powder (T5) and Muskmelon with cucumber seed powder (T6). The fruits and nuts spreads were analyzed for the presence of phytochemicals ?-carotene, polyphenols, tannins, flavonoids and antioxidant activity. The formulated fruits and nuts spreads were packed in polypropylene boxes, glass bottles and stored under refrigerated condition at 4°C. ?-carotene content was found to be high (634.21?g/g) in Mango with Pumpkin seed powder spread (T1), tannin content was higher (52.61 mg/g) in Papaya with Pumpkin seed powder spread (T2), flavonoid components were higher (3.25 mg/g) in Mango with Pumpkin seed powder spread (T1), and polyphenols content were found to be high (59.33 mg/g) in Papaya with Cucumber seed powder spread (T5). The antioxidant property was high in the Mango with Pumpkin seed powder spread (T1) when compared to all other treatments. Pumpkin seeds comprised of excellent amount of bioactive compounds. The pumpkin seed incorporated spread showed a high level of phytochemicals when compared to other spreads. This was ready to eat spread which had 3 months of shelf life under refrigerated condition is preferred for people of all age groups.

A total of 110 melon accessions with different geographical origins (18 countries) were screened for resistance to Fusarium oxysporum f.sp. melonis race 1.2 (pathotypes 1.2Y and 1.2W) using two artificial inoculation procedures. Twelve accessions showed some resistance to one or both strains. Three Japanese accessions, Shiro Uri Okayama (var. conomon), Kogane Nashi Makuwa, and C-211 (var. makuwa), and a Portuguese accession, BG-5384 (var. cantalupensis), showed the highest levels of resistance to both strains. The remaining eight accessions (all var. inodorus) had some level of partial resistance to 1.2W only. To our knowledge, this is the first time a high level of resistance to F. oxysporum f.sp. melonis race 1.2 has been identified in melon accessions of Western origin. The morphological traits of the 12 accessions that showed partial resistance were characterized to assess their suitability as resistance sources in melon breeding programs. Because most of the Western commercial cultivars belong to the cantalupensis, reticulatus, or inodorus botanical varieties, the resistant accessions from these varieties seem to be the most useful sources of resistance in breeding programs for developing melon cultivars of these types resistant to fusarium wilt race 1.2. The Portuguese accession BG-5384 had a high level of resistance within the Western types, and its morphological characteristics were fairly similar to some of the Western commercial cultivars.

Cowpea (Vigna unguiculata) is a neglected crop native to Africa, with an outstanding potential to contribute to the major challenges in food and nutrition security, as well as in agricultural sustainability. Two major issues regarding cowpea research have been highlighted in recent years—the establishment of core collections and the characterization of landraces—as crucial to the implementation of environmentally resilient and nutrition-sensitive production systems. In this work, we have collected, mapped, and characterized the morphological attributes of 61 cowpea genotypes, from 10 landraces spanning across six agro-ecological zones and three provinces in Mozambique. Our results reveal that local landraces retain a high level of morphological diversity without a specific geographical pattern, suggesting the existence of gene flow. Nevertheless, accessions from one landrace, i.e., Maringué, seem to be the most promising in terms of yield and nutrition-related parameters, and could therefore be integrated into the ongoing conservation and breeding efforts in the region towards the production of elite varieties of cowpea.
