Apricot is among the most important fruits in Morocco. This study aimed to determine the main physical, physicochemical, and biochemical quality criteria of three principal apricot cultivars in Morocco, namely, “Maoui,” “Canino,” and “Delpatriarca.” Different physicochemical and biochemical methods have been improved and adapted for the assessment of the apricot’s quality. Fruit of “Canino” has shown a good organoleptic quality due to interesting biometrics, richness of carotenoids (up to 113.67 μg of β-carotene g−1 of fresh weight (FW)), and an important content of soluble solids (SS) that reached 17.20 °Bx. “Delpatriarca” is rich in organic acids (27.35 g/kg FW for total acids) while “Maoui” has high water content (83.77%) and a SS content of 16.03 °Bx. The association of the total acidity and soluble solids determination with the use of the HPLC for determining the organic acids was very practical and effective in determining the organoleptic quality of the fruit. High correlations were detected between several attributes. In addition, an important relationship between total carotenoids concentration and color parameters (L ∗ a ∗ b ∗ ) demonstrated that these parameters are good for apricot quality and ripening indices. The obtained results also revealed the presence of a high variability among the quality criteria of the three apricot cultivars. These characteristics could be useful for promoting the consumption of the “Maoui” as fresh fruits and the use of “Canino” and “Delpatriarca” for industry derivatives products. The results could also be useful for new apricot breeding program among different eco-geographical groups of the Mediterranean region.

ABSTRACT Sweetpotato (Ipomoea batatas) is a root crop grown in many countries. This tuberous root is a source of energy, nutrients, and phytochemicals. In this study, bioactive compounds and physical and physicochemical qualities of sweetpotato genotypes were evaluated. Eight new genotypes of sweetpotato produced by Embrapa Hortaliças (orange-fleshed: MD09026-OF and MD09024-OF; cream-fleshed: MD09011-CF, MD09004-CF, MD10039-CF, and MD10004-CF; yellow-fleshed: MD09017-YF and MD12002-YF) and two cultivars used as controls (Beauregard and Brazlândia Roxa) were evaluated for color, soluble solids, dry matter, phenolic compounds, total carotenoids and β-carotene. Hue angles differed even between those sweetpotatoes with the same flesh color. The orange-fleshed genotypes MD09024-OF, MD09026-OF, and Beauregard, had the lowest L*, showing to be darker than the others. These sweetpotatoes also had the brightest flesh colors with higher C*. The orange-fleshed genotypes MD09026-OF and MD09024-OF were sweeter (10.55oBrix and 9.23oBrix) than Beauregard (5.12oBrix). Brazlândia Roxa had the highest dry matter content (38.05%), followed by the genotypes MD10004-CF, MD09017-YF, MD09026-OF MD10039-CF, and MD09011-CF, which showed similarity, ranging from 32.33% to 29.12%. The highest contents of total carotenoids were found for the orange-fleshed genotypes MD09026-OF (80.06 mg g-1) and MD09024-OF (70.56 mg g-1) and Beauregard (73.12 mg g-1). These same genotypes showed the highest total phenolic compounds (0.815 mg g-1 and 0.686 mg g-1, respectively). MD09026-OF showed the highest content of β-carotene (46.47 mg g-1). MD09026-OF was the most prominent genotype among those evaluated, as it showed the highest total carotenoid, β-carotene, phenolic compounds, and soluble solids content, in addition to a high dry matter content.

ABSTRACT The stability of cactus-pear powder, obtained by the process of spray drying for 40 days, was evaluated under controlled conditions of relative air humidity (83%) and temperature (25 and 40 °C). The whole pulp was characterized with regard to its physico-chemical parameters: pH, total titratable acidity, soluble solids, water content, total solids, ashes, reducing sugars, total sugars, non-reducing sugars, luminosity, redness, yellowness and water activity. The stored samples in powder were evaluated every 10 days for water content, water activity, total titratable acidity and color (luminosity, redness and yellowness). The whole pulp was slightly acidic and perishable, due to the high water content. During storage, the packages did not prevent water absorption, thus increasing water content and, consequently, water activity. Yellowness oscillated along the storage time, but the predominance of the yellow color was not affected.

However, those methods can’t fulfil the 15 cm settlement limit. Tanah bekas tempat pembuangan akhir (TPA) memiliki potensi besar untuk dimanfaatkan dalam bidang konstruksi. Tanah bekas TPA umumnya memiliki karakteristik serupa dengan tanah lempung berkadar air serta memiliki material organik dan anorganik dari timbunan sampah. Salah satu masalah dalam memanfaatkan tanah bekas TPA adalah rendahnya kualitas tanah yang mengakibatkan penurunan besar pada struktur. Perbaikan pada tanah bekas TPA diperlukan untuk mengurangi besarnya penurunan yang terjadi. Penurunan merupakan aspek penting dalam suatu perancangan konstruksi, maka dari itu batasan pada penurunan ditetapkan untuk menghindari penurunan yang berlebihan yang dapat merusak struktur. Permodelan menggunakan beban struktur 1,2,3, dan 4 lantai dan dihitung penurunan yang terjadi pada fondasi dengan beban struktur terbesar. Penampang fondasi berbentuk lingkaran mempertimbangkan beban percobaan hingga 4 lantai cocok untuk fondasi dangkal. Stabilisasi tanah secara kimiawi menggunakan 2 metode yaitu Sodium Hidroksida 6% dan batu kapur 3-4,5%. Berdasarkan hasil perhitungan, didapati stabilisasi menggunakan Sodium Hidroksida lebih efektif dalam mengurangi penurunan tanah yang terjadi dan mampu mengurangi besarnya penurunan hingga 32,42% pada beban struktur 4 lantai. Namun, stabilisasi tanah menggunakan kedua metode belum dapat mencapai batas aman penurunan sebesar 15 cm.

Ensuring an attractive commercial appearance of egg yolks involves the introduction to the feed of laying hens of the dyes of various origins. Recently, egg producers have preferred natural dyes, which include carotenoids: lycopene and astaxanthin, which can be deposited in chicken egg yolks. The aim of this study was to determine the quality of egg yolks, colour intensity and carotenoid composition of yolks when oil extracts of lycopene (20, 40 and 60 mg/kg feed) or astaxanthin (10, 20 and 30 mg/kg feed) are included in the chickens’ diet. 45 High Line W36 chickens at the age of 24 weeks were used for the experiment. Feeding laying hens with supplements of lycopene oil extracts at doses of 30, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of feed for 30 days in increasing concentrations did not affect egg weight, albumen height, Haugh unit, strength and the thickness of the shell. The addition of lycopene to the diet of chickens at doses of 20 mg/kg of feed increased the content of lycopene, unidentified carotenoids and the total content of carotenoids in the yolks, but did not change the intensity of their colour. Increasing the dose of lycopene in the diet of chickens to 40 and 60 mg/kg of feed increased the content of lycopene in yolks and the intensity of their colour to 7.4 and 8.0 points against 5.6–6.1 points in the control, but did not affect the content of β-carotene and total carotenoids in the yolks. The addition of astaxanthin oil extract at doses of 10, 20 and 30 mg/kg of feed increased the content of astaxanthin, β-carotene and total carotenoids in chicken egg yolks and increased the intensity of their colour to 12.8, 14.8 and 14.4 points on a 16-point colour scale YolkFanTM. To obtain chicken table eggs with a given colour of the yolks, it is advisable to use the addition of astaxanthin oil extract in doses from 10 to 20 mg/kg of feed for 30 days. The results of the research can be used to develop a technology for the production of functional table eggs enriched with carotenoids of natural origin with an attractive colour for consumers.

ABSTRACT Campomanesia rufa (O. Berg) Nied. is a native Cerrado species that presents great edible potential. However, it is a species “in danger of extinction” as recommended by the International Union for the Conservation of Nature (IUCN). No technical and scientific information about the species exists, thus demonstrating the importance of its research. The present work aimed at the physical and chemical characterization of immature and mature C. rufa fruits. The fruits showed a change in coloration from green (b * = 25.11, h = 122.43) to yellowish-green (b * = 34.26 , h = 115.73), an increase in mass (6.54 g to 10.88 g), diameter (23.76 mm to 28.03 mm) and soluble solids (8.00 to 10.80%). The fruits presented high levels of total (1246.35 mg 100 g-1) and soluble pectin (195.93 mg 100 g-1), high water content (78.86 g 100 g-1), low pH value (3.40), and high citric acid content (1.2%). However, the fruits had low protein (0.81 g 100 g-1), lipid contents, and low caloric values (64.76 kcal 100 g-1). The fruits presented significant values of carotenoids, phenolic compounds (312.47 mg 100 g-1), vitamin C (263.60 mg 100 g-1) as well as good in vitro antioxidant activity (1862.81 µM g-1). The results obtained indicate that C. rufa fruits showed a similar composition to the fruits of other Campomanesia species, and their biological properties should be investigated additionally under in vivo conditions.
