Comparison Of Volatile Compounds Between The Green And Yellow Ripening Fruits Of Four Guava Species, Wang Haibo, Zhong Dan, Lin Zhixin, Ou Qiyun, Qiu Guiyu
Food and Machinery
[Objective] This study aimed to analyze the differences in volatile compounds between the mature green and mature yellow fruits of guava. [Methods] The volatile compounds in 4 kinds of guava fruits during the mature green and mature yellow were detected by gas chromatography ion mobility spectroscopy (GC-IMS). [Results] 130 volatile compounds were detected in 4 kinds of guava fruits ("Yanzhihong", "Sijihong", "Baizhenzhu" and "Siji"). Qualitative analysis showed that the fruit flavored ethyl trans-2-butenate, the grass flavored 2-hexenal and hexanal were the volatile compounds with the highest content among the 4 kinds of guava fruits. The content of volatile components in …

Objective: In order to improve the situation that existing fruit recognition and classification methods rely on manual operation and complex equipment. Methods: A lightweight model YOLO-FFD (YOLO with fruit and freshen detection) was proposed, which based on the YOLOv5 framework. Firstly, LightweightC3 was designed as the basic unit of the backbone feature extraction network based on the depth separable convolution and GELU activation function, which reduced the number of model parameters and computation, and speeds up the convergence of the model. Secondly, EnhancedC3, a large kernel depth separable convolution module, was used to improve the neck of the original model, …

Fruit Classification System Based On The Pressure Sensor Coupled With Support Vector Machine, Wang Feifei, Liu Peng, Sun Fengwei, Zhou Qiong
Food and Machinery
Objective: To improve fruit classification accuracy while considering low computational cost and low sensor cost. Methods: A fruit classification system based on capacitive pressure sensor was proposed. The system used support vector machine algorithm with a Gaussian kernel function (GKF-SVM) to classify fruits. The capacitive pressure sensors used were made of thin copper sheets and a layer of vinyl acetate, and these sensors were fixed to the thumb and index finger of a polyamide spandex glove that simulates a robotic hand. The obtained capacitance value was expressed in the form of digital level, and the data was extracted by data …

Fruit Identification Using Improved Faster R-Cnn Model, Jian Yanping, Sang Yanli, Li Yueru
Food and Machinery
Objective: To improve the identification accuracy of fruit categories. Methods: An identification method for fruit categories was established based on an improved Faster regional convolutional neural network (Faster R-CNN) model. Firstly, the regularization method was used to attenuate the weight of some high-dimensional parameters to effectively solve the over-fitting problem that may occur in the training process. Then, two loss functions, a likelihood function and a regularization function, were added to the Faster R-CNN framework to optimize the convolution layer and the pooling layer. Additionally, the least square method was utilized to solve the objective function of fruit recognition. Finally, …
Investigating Quality Attributes And Wine Production Methods Of Arkansas-Grown Grapes, Amanda Fleming
Investigating Quality Attributes And Wine Production Methods Of Arkansas-Grown Grapes, Amanda Fleming
Graduate Theses and Dissertations
Grapevines (Vitis species) are grown worldwide to produce table grapes, juice grapes, dried grapes, and wine with the United States as one of the world’s largest wine and grape producers. Though not a large contributor to the U.S. grape and wine industry, Arkansas’ industry plays an important role in the state’s agritourism and economy. Most grapes grown in Arkansas’ warm climate include native species, such as muscadines (V. rotundifolia) and hybrids (crosses of Vitis species). Two important hybrid red wine grapes grown in Arkansas are Chambourcin, grown commercially for its positive viticulture and enological quality, and Enchantment, a newer cultivar …

Research And Development Of Fruit Quality Sorting Machine, Wang Wen-Chao, Ge Feng-Li, Xu Wen-Kai, Zhao Lu-Hai, Li Juan
Food and Machinery
Objective: Improve the quality and efficiency of fruit quality sorting and reduce labor costs. Methods: A fruit quality sorting machine is designed to detect and sort for fruit quality. The sorting machine uses STC8A8K64S4A12 as the slave computer and uses Jetson Xavier NX as the master computer. The sorting machine can achieve the detection and sorting of the fruit on damage and sugar content by artificial intelligence. Results: The accuracy, resolution of sugar degree and speed of the sorter for detecting fruit were 99%, 0.1% and 7 200 h-1, respectively. Conclusion: The device can …

Comparative Effects Of Dehydration Processes On Physico-Chemical Changes In Fruits, Chang Yong Lee
Comparative Effects Of Dehydration Processes On Physico-Chemical Changes In Fruits, Chang Yong Lee
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Drying with the help of sun and wind is one of the oldest methods of food preservation known to man, but artificial drying, or dehydration, has been developed and used extensively only during the last two decades. The problem in dehydration is that the water content must be decreased sufficiently to maintain the stability of the product by retarding the rates of deteriorative biochemical, microbiological, and enzymatic reactions during subsequent storage. At the same time irreversible changes should not be brought about.
