Effects Of Period And Temperature On Quality And Shelf-Life Of Cucumber And Garden-Eggs Packaged Using Cassava Starch-Zinc Nanocomposite Film, Adeshina Fadeyibi, Zinash Delebo Osunde, Mohammed Gana Yisa
Journal of Applied Packaging Research
Nanocomposite film can be used to prolong the shelf-life of fruits and vegetables. This research was undertaken to investigate the effects of packaging period and temperature on the quality and self-lives of cucumber and garden-eggs packaged using cassava starch-zinc nanocomposite film. Hundred grams each of cucumber and garden-eggs were wrapped in a 200× 350 mm size nanocomposite film and low density polyethylene (LDPE) of 2.240± 1.076 × 10-10 gm-1Pa-1s-1 water vapor and 1.568± 0.084× 10-10 gm-1Pa-1s-1 oxygen gas permeability. The products were stored at 10−27oC temperatures …

Effects Of Storage Temperature And Duration On Pasting Properties Of Indica Rice, Xie Lan, Quan Ke, Liu Yan-Lan, Mo Xi-Ya, Zhu Hong, Zhou Xiao-Ling, Huang Shou-En, Yi Cui-Ping
Food and Machinery
The pasting properties of three cultivars of Indica rice (Zhefu 802, Yuanlong 8462, ‘Zaoxian 5-34’), at different temperature (36, 25, and 4 ℃) during 0~3 months storage, were studied to understand effects of storage temperature and duration. The results indicated that the storage time was significant (P＜0.05) correlated to pasting properties of rice when stored at 36 ℃. The peaks of viscosity and breakdown both increased first and then decreased. The cool paste viscosity increased first and then stabilized, and setback and pasting temperature showed an upward trend. However, the pasting properties varied depending on the rice cultivar. When rice …
Study On Correlation Between Forced Ventilation Precooling And Temperature Distribution Of Strawberry In Fresh-Keeping Transportation, Cheng Li-Li
Food and Machinery
Studied the temperature distribution of strawberry during commercial forced air pre-cooling, quantifies the relationship between environment and product temperature, and evaluated the pre-cooling duration. Results: the half-cooling time (HCT) inside the pre-cooled tunnel was about twice the external semi-cooling time, and the HCT outside the tunnel was closely related to the internal HCT. The temperature prediction from a limited number of sensors detected a temperature change of up to 7 ℃ at the end of pre-cooling, indicating that in some cases the pre-cooling time should be extended to increase the uniformity of the cooling temperature.
Design And Test Of An On-Line Measuring System For Vacuum Freezing Dryer, Zhao Hai-Bo, Peng Xin, Wu Kun, Dai Jia-Ao
Design And Test Of An On-Line Measuring System For Vacuum Freezing Dryer, Zhao Hai-Bo, Peng Xin, Wu Kun, Dai Jia-Ao
Food and Machinery
To obtain real-time water contents and temperatures of vacuum freezing drying process, and to facilitate monitoring of drying process, a novel online measuring system (OMS) for vacuum freezing dryer was proposed and experimental tests were carried out. The system was composed of a microcontroller, a strain pressure sensor, a thermal resistance, modulus conversion modules, an OLED screen and other components. Wireless data transmission was used, and temperature correction and vibration reduction were carried out in the design. Experimental tests showed that the system could be used to measure the weight, moisture content and temperature in real time during the vacuum …
