Abstract:
... The relationship between microscopic and macroscopic properties in fat-continuous dispersions is multifaceted compared to bulk oils, which limits the ability to extrapolate results from bulk systems towards complex formulations. The impact of confectioner’s sugar on the crystallization and rheology of palm oil (PO) and mid-fraction blend (PMF) was investigated in this study. Adding sugar significa ...

Abstract:
... An acoustic setup was developed to simultaneously detect the resonant frequencies f1 from equator and f2 from calyx shoulder of pear (Pyrus bretschneideri Rehd.). A proposed index based on these two frequencies was used for firmness evaluation of non-spherical pear. We confirmed the stability of this setup by repeatability analysis of acoustic response signal. When predicting the firmness of pears ...

Abstract:
... In this research, the efficacy of two different ethanol treatments on astringency removal was evaluated in 'Hiratanenashi' and 'Denkuro' persimmon cultivars. Fruits from both cultivars were treated with ethanol on-tree or after harvest. A silica-ethanol patch was attached onto the peel of individual fruits on-tree or harvested fruits kept under the tree for 3 days. On-tree treated 'Hiratanenashi' ...

This study aimed to describe the effects of the cooking condition, including water ratio (WR) and soaking time (ST), on the texture of rolled barley, and to evaluate its β-glucan content, total phenol content and in vitro starch digestibility. Rolled barley (75 g) was soaked in 1.5×, 2.0× and 2.5× weight of aliquots of Milli-Q water at room temperature, for 30 and 90 min, respectively, and then co ...

The aim of this investigation was to evaluate the effect of pH variation, sucrose, salt and hydrocolloid gums (xanthan, guar, karaya and locust bean) addition on the gelling properties and the water holding capacity (WHC) of the egg white (EW) gel. Tree levels of pH (4.5, 6.5, 8.0), sucrose/salt (1, 3, 6% w/w) and hydrocolloids (0.01%, 0.10%, 0.20% w/w) were tested in this study. Obtained results ...

Abstract:
... ‘Yali’ pear (Pyrus bretschneideri Rehd. cv. Yali) is susceptible to core browning after a long term of cold storage. In this study, the effects of 1-methylcyclopropene (1-MCP) with different concentrations (0, 0.25, 0.5, 1.0 μL L−1) on the quality and core browning of ‘Yali’ pear fruit were investigated. The results showed that 1-MCP significantly reduced the ethylene production, kept higher firmn ...

Abstract:
... For blueberry, harvest readiness is based on skin color, with fruit being considered ready to pick when the berry skin reaches 100% blue coverage. The extended bloom period for the blueberry inflorescence and uneven developmental rates can yield fully blue fruit that are widely different in physiological maturity, at any given harvest date. The objective of this study was to determine the inherent ...
