This paper presents a review of cactus-pear juice production. Its technological characteristics are considered, as well as the main difficulties in obtaining high-quality juice. Acidity, pigments, aroma, and other components play an important role in the cactus pear juice processing. Betalain and chlorophyll are present in purple and green cactus pear juices, and heat treatment of the juices af...

This study was performed to compare the quality and functionality of broccoli juice as affected by extraction method. Broccoli juice was extracted using method I (NUC Kuvings silent juicer), method II (NUC centrifugal juicer), and method III (NUC mixer), and the quality properties of the broccoli juices were analyzed using three different methods. Additionally, the antioxidative, anticancer, an...

Background: Lime juice is a nutritious drink, which is generally consumed for its' refreshing properties, nutritive value, vitamin content, and health benefits. Therefore, the chemical and microbiological quality of the traditional and industrial lime juice produced in Kashan city was assessed. Methods: In this descriptive cross-sectional study, a total of 106 samples were collected and screene...

Foraging animals must often decide among resources which vary in quality and quantity. Nectar is a resource that exists along a continuum of quality in terms of sugar concentration and is the primary energy source for bees. Alternative sugar sources exist, including fruit juice, which generally has lower energetic value than nectar. We observed many honeybees (Apis mellifera scutellata) foragin...

It is well known that eating fruits and vegetables lowers the risk of chronic diseases such as heart disease and cancer. The question of what is/are the active ingredient(s) is still unresolved. The initial hypothesis was that the antioxidant vitamins were responsible. However, recently the polyphenols have been investigated since they have been found to have beneficial properties such as being...

The objectives of this study were to determine the physicochemical characteristics, sensory acceptability and microbial quality of fermented fresh water fish (Betok-Anabas testudineus Bloch) locally known as Wadi Betok, which was prepared by using 15% w/w salt and addition of palm (Arenga pinata) sugar (0, 5, 10 and 15% w/w) and lime (Citrus aurantifolia) juice (0, 2, 4 and 6% w/w). An interact...

present study examined the effect of storage conditions (packaging type, storage temperature and time) on physicochemical and microbial properties of tomato juice. samples were stored for one and three months in two packaging types (bottle and doypack) at 4, 25 and 35oc. results obtained from testes (ph changes, acidity, solid soluble content, vitamin c content, and microbial load) showed that ...
