An innovative solid liquid extraction technology: use of the naviglio extractor for the production of lemon liquor.
This document is a review on solid-liquid extractive techniques and describes an innovative solid-liquid
extraction technology using the Naviglio Extractor®. Also explained is an application for the production
of alcoholic extract from lemon peel. The alcoholic extract, mixed with a sugar and water solution in the
right proportions is used to make a well known Italian lemon liquor commonly named "limoncello".
Lemon liquor is obtained utilizing the Naviglio Extractor®; the procedure used is fast and efficient and
uses about half the weight of lemon peel per volume of ethyl alcohol used for the extraction of the
odorous and taste responsible compounds, compared to the commonly used extraction procedures. To
test the consumer’s preference and compare the taste of the liquor obtained with that obtained by peel
maceration from the same lot of lemons and obtained using the traditional recipe, a consumer test has
been carried out. One hundred people, chosen from among frequent consumers of limoncello, tasted
the two lemon liquors, and evaluated intensity of aroma, colour, alcohol taste and sweetness. In about
81% of the preferences, the liquor obtained using the Naviglio Extractor® was preferred. The extraction
process used allows the ethanol from used up lemon peel to be totally recovered so that these can be
disposed of as non toxic waste or used in agriculture or as cattle feed
Convolutional Neural Networks for the segmentation of microcalcification in Mammography Imaging
Cluster of microcalcifications can be an early sign of breast cancer. In this
paper we propose a novel approach based on convolutional neural networks for
the detection and segmentation of microcalcification clusters. In this work we
used 283 mammograms to train and validate our model, obtaining an accuracy of
98.22% in the detection of preliminary suspect regions and of 97.47% in the
segmentation task. Our results show how deep learning could be an effective
tool to effectively support radiologists during mammograms examination.Comment: 13 pages, 7 figure
Effect of tomato by-products in the diet of Comisana sheep on composition and conjugated linoleic acid (CLA) content of milk fat
To evaluate the effect of supplementing the diet of Comisana sheep with by-products from industrial tomato manifacture on the composition and conjugated linoleic acid (CLA) content of milk fat, two groups of 50 ewes each were fed either total mixed ration standard (TMRS) or total mixed ration with added tomato by-products (TMRA). Milk fat composition was determinated by HRGC. The milk fat content for animals fed the TMRA diet increased by 6,41% aafter six weeks, compared with the animals fed the TMRS diet. The CLA content in the milk fat for the group of animal fed the TMRA diet was 19,8% higher than for those fed the TMRS diet. The fatty acid composition showed an increase in the amount of PUFA; the n-3:n-6 ratio increased by 13% in the milk from sheep fed with the TMRA diet
