Measuring internal maturity parameters contactless on intact table grape bunches using NIR spectroscopy
(Frontiers Media, 2019)The determination of internal maturity parameters of table grape is usually done destructively using manual methods that are time-consuming. The possibility was investigated to determine whether key fruit attributes, namely, ... -
Drying kinetics of pomegranate fruit peel (cv. Wonderful)
(Elsevier, 2019)Pomegranate juice processing produces large amount of peel as by-product or waste which is a potential source of raw material for food and other bioprocessing industries. Drying the peel offers opportunities for value ... -
Light regulation of carotenoid biosynthesis in the peel of mandarin and sweet orange fruits
(Frontiers, 2019-10-15)Carotenoids are the pigments responsible for the coloration of the peel and pulp of Citrus fruits. Light is one of the major environmental factors influencing coloration and carotenoid content and composition of fleshy ... -
Application of gum arabic and methyl cellulose coatings enriched with thyme oil to maintain quality and extend shelf life of “Acco” pomegranate arils
(MDPI, 2020-12-01)The effects of gum arabic (GA; 1.5% w/v) and methyl cellulose (MC; 1% w/v) enriched with thyme oil (TO; 0.25 and 0.5% v/v) on the quality of “Acco” pomegranate arils were studied. Coating treatments, namely, MC, MC + ... -
The effects of postharvest treatments and sunlight exposure on the reproductive capability and viability of Phyllosticta citricarpa in citrus black spot fruit lesions
(MDPI, 2020-12-21)Citrus black spot (CBS) is caused by Phyllosticta citricarpa, which is classified as a quarantine organism in certain countries whose concerns are that CBS-infected fruit may be a pathway for introduction of the pathogen. ... -
Food preservative capabilities of grape (vitis vinifera) and clementinemandarin (citrus reticulata) by-products extracts in South Africa
(MDPI, 2019-03-22)The drive towards sustainable food systems coupled with increased consumer sophistication have prompted innovation in waste valorization. Grape and citrus processing by-products, abundant in the Mediterranean and tropical ... -
Mathematical modelling of blanch-assisted drying of pomegranate (Punica granatum) arils in a hot-air drier
(MDPI, 2020-05-20)The effect of blanching conditions on the hot-air drying kinetics of three pomegranates (cvs. “Acco”, “Herskawitz” and “Wonderful”) were assessed. Water blanching conditions considered were 90 °C for 30 s, 90 °C for 60 s, ... -
Rapid methods for extracting and quantifying phenolic compounds in citrus rinds
(Wiley Open Access, 2016)Conventional methods for extracting and quantifying phenolic compounds in citrus rinds are time consuming. Rapid methods for extracting and quantifying phenolic compounds were developed by comparing three extraction solvent ... -
Mating compatibility and competitiveness between wild and laboratory strains of Eldana saccharina (Lepidoptera : Pyralidae) after radiation treatment
(Florida Entomological Society, 2016)The efficacy of the sterile insect technique (SIT) applied as part of area-wide integrated pest management (AW-IPM) depends on efficient transfer of sperm carrying dominant lethal mutations from sterile males to wild ... -
Classification of 'Granny Smith' apples with different levels of superficial scald severity based on targeted metabolites and discriminant analysis
(German Botanical Society, 2016)To study the metabolic changes in ‘Granny Smith’ apples with different severities of superficial scald, fruit were stored in normal refrigerated air (0°C, 95% RH) for 12 weeks followed by 7 d shelf-life under room conditions ... -
Berry abscission in vitis vinifera L. cv. Waltham Cross : changes in abscission-related factors during berry development
(South African Society for Enology and Viticulture, 2005)During the 1999 season, changes in total soluble solids (TSS), titratable acids (TA), pedicel diameter, berry diameter, berry mass and fruit removal force (FRF) were determined at biweekly intervals from 27 until 111 days ... -
The influence of storage duration and elevation of storage temperature on the development of berry split and berry abscission in vitis vinifera L. cv. Thompson seedless table grapes
(South African Society for Enology and Viticulture, 2005)Thompson Seedless grapes, packed in non-perforated low density polyethylene bags, were cold stored at -0.5°C and RH 83% for 0, 1, 2, 4 and 8 weeks. After storage at -0.5°C for these periods, the grapes were stored for ... -
Stability of total phenolic concentration and antioxidant capacity of extracts from pomegranate co-products subjected to in vitro digestion
(BioMed Central, 2016-09)Background: Co-products obtained from pomegranate juice processing contain high levels of polyphenols with potential high added values. From value-addition viewpoint, the aim of this study was to evaluate the stability of ... -
Internal flesh browning of ‘Cripps’ Pink’ apple (Malus domestica Borkh.) as influenced by pre-harvest factors and the evaluation of near infrared reflectance spectroscopy as a non-destructive method for detecting browning
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The successful marketing of ‘Pink Lady’™ apples produced in South Africa is under pressure due to internal flesh browning (IFB) development. IFB incidence is increased by long term controlled atmosphere ... -
Physiological responses of pears to exogenous ethylene and pre-harvest factors influencing post-harvest quality with reference to 'Forelle' and 'Packham's Triumph' pears
(Stellenbosch : Stellenbosch University, 2000-04)ENGLISH ABSTRACT: The major sites for fruit ripening and softening are found in the middle lamella where enzymatic and non-enzymatic mechanisms seem to degrade pectin polymers to a more soluble state and in the primary ... -
