Researchers are endeavouring to develop prediction models to determine anthocyanin content in a simpler and more accurate way. The aim of this study was to investigate whether there is a relationship between anthocyanin and some fruit characteristics (width, length, weight, L, a, b, chroma, hue) in black mulberry (Morus nigra) fruit. With the outputs of the study, it is aimed to provide preliminary information for the models to be developed for anthocyanin estimation in future studies. The study material, black mulberry fruits, was collected from a single black mulberry tree in Kemalpaşa village of Tokat province in 2022. Harvesting of the fruits continued for two weeks as raw, semi-ripe and ripe. A total of 586 fruits were individually evaluated and the weight, width, length, colour parameters (L*, a*, b*, b*, chroma, and hue) and total monomeric anthocyanin contents of each fruit were determined. Then, Pearson correlation coefficients between the variables were determined. Stepwise regression analysis was used to find the appropriate model to explain the change in the dependent variable anthocyanin with independent variables (length, width, weight, L, a, b, chroma, hue). After the multiple regression model was established, residual analysis was performed to see the outliers in the full model and to check the accuracy of the model. As a result of the study, it was observed that anthocyanin content could be predicted by colour parameters up to a certain maturity stage. This relationship was found to weaken at the ripeness stage when the fruit colour turns black.","PeriodicalId":505931,"journal":{"name":"Turkish Journal of Food and Agriculture Sciences","volume":"265 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140249400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, the trials were carried out under five different orchard yield conditions (71.74, 143.48, 215.23, 286.97, and 358.72 kg ha-1). As a result of the experiments, the product loss and foreign material removal efficiency obtained by hazelnut harvesting with a hazelnut harvesting machine with a mechanical effective harvesting unit were determined between 34.39-37.92% and 96.91-95.62%, respectively. The product losses and foreign material removal efficiency values obtained by hazelnut harvesting machine with pneumatic effective harvesting unit were determined between 6.84-5.07% and 93.33-86.73%, respectively. The data to be obtained as a result of the study, in addition to examining the mechanical harvesting of hazelnuts, will enable the reasons for the changes that may occur in the performance characteristics of existing machines to be explained and suggestions can be made for improvement.","PeriodicalId":505931,"journal":{"name":"Turkish Journal of Food and Agriculture Sciences","volume":"52 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adetola, Idris Mustapha","doi":"10.53663/turjfas.1385212","DOIUrl":"https://doi.org/10.53663/turjfas.1385212","url":null,"abstract":"Yam is a versatile crop and plays a vital role in tropical regions, where it can be transformed into various food products. Peeling is an essential step in the processing of yam, as it increases its value. While manual peeling with knives is common in households, larger-scale production requires the use of yam peeling machines. The objective of this study was to analyse and enhance the performance of an existing yam peeling machine. The key components of the machine include the machine frame, a wire mesh-like drum, a speed reduction gear motor, a pumping machine, sprockets, pipes, and a water container. The yam peeler is powered by a three-phase 2 hp electric motor. The machine was tested on three different types of yams with varying moisture contents and at different speeds. Various performance parameters such as peeling efficiency, peeling capacity, flesh loss, and time efficiency were evaluated. Statistical analysis and SPSS models were utilized to examine the relationship between different factors and the performance metrics of the machine. The study revealed that as the peeling speed increased, the efficiency decreased. The peeling efficiency ranged from 63.27% to 92.74%, peeling capacity ranged from 2.28 kg/hr to 11.34 kg/hr, and flesh loss varied from 7.26% to 36.73%. The moisture content of the yams, peeling speeds, and tuber morphology were found to have significant effects on peeling efficiency, flesh loss, peeling capacity, and time efficiency. The yam peeler production cost is estimated to be $150. The machine demonstrated suitability for small-scale food industries due to its low cost and minimal maintenance requirements.","PeriodicalId":505931,"journal":{"name":"Turkish Journal of Food and Agriculture Sciences","volume":"115 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
