Abstract:
... Aroma is an important trait of ‘Nanguo’ pear (Pyrus ussuriensis Maxim.), and esters are the main aroma components in the fruit. Refrigeration prolongs the storage period of the fruit but results in evident loss of esters. Here, we treated the refrigerated fruit with 1000 μL L⁻¹ Ethephon solution and found that exogenous ethylene treatment raised the biosynthesis of ten individual esters, and up-re ...

Formaldehyde (FA) is considered as a carcinogen and classified as a Type 2 hazardous substance but it is still illegally use as a preservative in many foods to prevent them from spoilage and increase storage time. Current technologies for quantifying FA in foods are expensive, requi ...

This study investigated how pulsed light (PL) postharvest treatment influences acerola ripening physiology and quality, thus physiologically mature acerola ‘Okinawa’ were treated with PL (0.6 J.cm⁻²) and stored for 16 days at 10 °C. Compared to untreated, PL-treated acerola showed a 5% reduction in climacteric respiration with 78.65 mol CO₂ kg⁻¹ h⁻¹ and a one-day delay in ethylene peak of 2.65 µL ...

Abstract:
... One of the major challenges to improving the performance of sodium-ion batteries at low temperatures is to develop effective anode materials with novel structures and fast reaction kinetics. Currently, converting electrode materials from the crystalline to amorphous state is an effective approach to fabricate the electrode material with high sodium storage performance. Herein, a three-dimensional ...

In this study, pectic oligosaccharides of orange peel (OPOs) were isolated and their structure characterized, and then screened according to anti-glycation level compared with aminoguanidine (AG). The results indicated that OPOs mainly included two components, and the main component has more than 50 % inhibition level for the seven glycation products at 60 °C for 40 h. At the accelerated storage t ...

Abstract:
... The integration of thermal energy storage in chilled water systems is an effective way to improve energy efficiency and is essential for achieving carbon emission reduction. However, the commonly used large-scale thermal energy storage needs significantly larger space, which hinders the wide application of thermal storage in large number of existing buildings. Unlike previous studies, this study i ...
