I am looking for a cost effective, simple and environment friendly way to extract pulp out of agricultural wastes in large scales. What is the best way?
Steam extraction using whole fruit with added pulp juice produced the highest yield (70.3%). Fructose and glucose were predominant sugars and malic was the predominant acid in all extracted juices.
Plant extracts have gained importance in insect control, being considered environmentally safe, less hazardous to non target biota, simple inexpensive and can be applied effectively by using techniques more suitable for developing countries. Several plant extracts were effective as potential acute or chronic insecticides, insect growth inhibitors or antifeedants against a variety of insect species
Six juice extraction methods for mayhaw cultivar Texas Star were evaluated for percent juice yield, pH, °Brix (soluble solids), titratable acidity (TA), sugar/acid ratio, sugar and organic acid contents, and color of extracted juices from fresh fruit. Methods study steam extraction using whole fruit with added pulp juice (SEP) or without added pulp juice (SE), cold-press extraction using whole fruit (CPE) or finely ground fruit (CPEG), hot-press extraction using finely macerated fruit pulp (HPEG), and hot-press extraction in combination with a pectolytic enzyme pretreatment (ENZ). Juice quality determined by HPLC analysis of sugar and individual organic acid. Juice quality and extraction efficacy were significantly (P ≤ 0.05) affected by extraction. Steam extraction using whole fruit with added pulp juice produced the highest yield (70.3%). Fructose and glucose were predominant sugars and malic was the predominant acid in all extracted juices. SEP produced juice with lowest amount of total sugars.
