To ascertain the most discriminant variables for three pumpkin species principal component analysis (PCA) was performed. Twenty-four parameters (pH, conductivity, sucrose, glucose, total soluble solids, L*, a*, b*, individual weight, edible rate, firmness, citric acid, fumaric acid, l-ascorbic acid, malic acid, PPO activity, POD activity, total flavonoids, vitamin E, total phenolics, DPPH, FRAP, β-carotene, and aroma) were considered. The studied pumpkin species were Cucurbita maxima, Cucurbita… 
Comparative In Vitro Antioxidant Capacity and Terpenoid Profiling of Pumpkin Fruit Pulps from a Serbian Cucurbita maxima and Cucurbita moschata Breeding Collection
The findings have helped to identify the most suitable antioxidant-rich varieties to select for national breeding programs for improving human health and provide valuable information to the overall current understanding of the potential health benefits of pumpkins and the discriminant triterpenoids underlying the C. maxima and C. moschata accessions investigated here.
Antioxidant potential of phytochemicals in pumpkin varieties belonging to Cucurbita moschata and Cucurbita pepo species
It was shown that the antioxidant activity is more affected by the type of cultivar than by the pumpkin species, and cultivars such as ‘Delicata’, ‘Baby Boo’ and ‘Cream of the Crop’ were characterized by particularly high antioxidant activity.
Characterization and Discrimination of Apples by Flash GC E-Nose: Geographical Regions and Botanical Origins Studies in China
Forty-one apple samples from 7 geographical regions and 3 botanical origins in China were investigated. A total of 29 volatile compounds have been identified by flash GC E-nose. They are 17 esters, 5
Extraction of Carotenoids from Pumpkin Peel and Pulp: Comparison between Innovative Green Extraction Technologies (Ultrasonic and Microwave-Assisted Extractions Using Corn Oil)
This study supports the use of innovative green extraction techniques to obtain bioactive pigments like carotenoids and antioxidant activities of pulp and peel of two varieties of pumpkin.
Optimization of Extraction Conditions for the Antioxidant Potential of Different Pumpkin Varieties (Cucurbita maxima)
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
Physicochemical and Sensory Properties of Pumpkin (Cucurbita moschata D) and Arrowroot (Marantha arundinaceae L) Starch-based Instant Porridge
Pumpkin is a potential source of vitamin A and antioxidant. Arrowroot starch as the source of carbohydrates contains a low glycemic index. However, the utilization of pumpkin and arrowroot starch as
Utilizing Pattern Recognition Methods for Detecting the Adulteration of Glucose and Fructose in Honey
The aroma of honey is one of the important parameters in honey grading and that is depended on several factors, such as geographical origin, climate, botanical and environmental conditions. The aim
Commercial Bio-Packaging to Preserve the Quality and Extend the Shelf-Life of Vegetables: The Case-Study of Pumpkin Samples Studied by a Multimethodological Approach
From microbiological analyses total microbial count was below the threshold value up to 7 days for samples in all the films, and 11 days for biofilm C, the most promising packaging for microbiological point of view, aroma analysis was also carried out.
Influence of Marination with Aromatic Herbs and Cold Pressed Oils on Black Angus Beef Meat
The main goal of the present study was to analyse the influence of different cold pressed oils and aromatic herbs during marination process on the nutritional, textural, and sensory attributes of the final grilled sirloin samples.


Study of phenolic compound and antioxidant activity of date fruit as a function of ripening stages and drying process
Edible parts of two varieties of date palm fruits from Iran were analyzed to determine their phenolic compound and antioxidant activities (AA) and result showed that TPC and AA varied with temperature and decreased by increase of drying temperature.
Identification and quantification of carotenoids in pumpkin cultivars (Cucurbita maxima L.) and their juices by liquid chromatography with ultraviolet-diode array detection
The carotenoid pigments of different cultivars of Cucurbita maxima L. (pumpkin) were investigated in pulp, peel and genuine juice by means of HPLC. In dependence of the variety different
Determination of the Optimum Sun-Drying Time for Vitis vinifera L. cv. Tempranillo Grapes by E-nose Analysis and Characterization of Their Volatile Composition
