Instrumental Texture Profile Analysis (TPA) of Cucumber Fruit as Influenced by Its Part and Maturity Stage

Abstract

Instrumental texture profile analysis (TPA) of Nandini cucumber fruit, was measured as a function of its parts (stalk, mid and blossom), and maturity stages. These textural parameters; hardness, springiness, adhesiveness, gumminess, stringiness, fracturability, and chewiness of the fruit were measured; over a course of four maturity stages, 6, 9, 12 and 15 Days after Peak Anthesis (DAPA). The texture profile analysis was done by using the Warner-Bratzler shear force (WBS) method, and the results showed that maturity stage and fruit part significantly (P ≤ 0.05) influenced all the textural parameters evaluated. Over the course of maturation, all the parameters investigated were found to increase. During maturation, the stalk, mid and blossom hardness increased by 25, 26 and 32% respectively; springiness increased by 6.4, 7.7 and 6.2 % in the stalk, mid and blossom; gumminess increased by 57.7, 57.4 and 42.2% in the stalk, mid and blossom; chewiness increased by 60.5, 63.1 and 47% in the stalk, mid and blossom; fracturability increased from 89.13 to 118.29, 82.76 to 110.7 and 62.28 to 90.

On the Assessment of Strawberries’ Shelf-Life and Quality, Based on Image Analysis, Physicochemical Methods, and Chemometrics

“…This compound does not react with DCPIP (2,6-dichlorophenolindophenol), in contrast to the free form of ascorbic acid. This hypothesis may be confirmed by Richardson et al [35,36], who identified this particular derivative of vitamin C in fruits and leaves from the Rosaceae family.…”

Linseed and xanthan gum in algae pasta: textural, sensory and antioxidant characteristics

“…Pasta samples control, L1, X3 and Al were cooked in distilled water to OCT, and after draining, were served to twelve selected and semi-trained tasters. Tasters evaluated the products for flavour, appearance, texture and overall acceptability using a 7-point hedonic scale ranging, from 1 (extremely dislike) to 7 (extremely like), for each sensory characteristic ( € Ozyurt et al, 2015). The panellists took their test in individual sensory booths in a sensory analysis room (with temperature and lighting control), with access to cutlery, napkins and glass cups of mineral water that provided to clean the palate between samples.…”

“…Gumminess and chewiness are defined as the energy required to disintegrate a semisolid or solid food until it is ready to be swallowed (Nyorere, 2018). Milde et al (2020) noted that chewiness increased when XG was incorporated.…”
