  • Storage Plans for Value Added MFP Products – Van Dhan
    Storage Plans for Value Added MFP Products – Van Dhan Storage Guidelines for MFP and Value Added Products - PMVDY After the processing of Minor Forest Produce (MFP) in Van Dhan Vikas Kendras (VDVKs), the need for storing the value added products becomes imperative as they must be preserved until needed for consumption. This document provides guidelines specifying how locally processed items should be preserved. Proper Storage Requirements: Any given storage system must be easy for maintenance and management. A good storage must be prevented from moisture and excessive air current. A good storage system enables free access in terms of regular check to access the state of the product. Any stored produce must be protected from pests, rodents and birds by allowing proper storage hygiene and maintenance. The storage facility must give ease of loading and offloading as the need arises. This is to create accessibility of the product. Storage Methods: Many people store their produce in the drying place itself which is not the right way of storage. Often the root or leaves are not dried properly which can cause harm if not stored properly. It is best to transfer the clean, dry produce to a cool, moisture-free place where rats and insects cannot follow. Warehouses are large houses or spaces that are commonly used as storage structures. They are especially constructed for the protection of the quantity and quality of processed agricultural products. They ways in which processed items can be stored are as follows: Bag Storage: This is a very popular form of storage. Transportation of the product is done in jute bags, the bags are easy to handle and the jute bag allows you to store different items in the same room.

Rapid oil production occurred at three stages of seed maturity. Stillingia oil syntheses in seed kern proceeded more rapidly than stillingia tallow on the kern at early stage. Analytical data for components in immature seed suggest that the pathway of seed oil synthesis is the same as Kennedy's pathway. However, the appear ance of monoglycerides indicates the existence of a side pathway. From specific positional distribution of fatty acids in mono-, di-, and triglyceride from immature seed, synthetic process of glyceride structure was discussed.

The use of biodiesel has been widely accepted as an effective solution to reduce greenhouse emissions. The high potential of biodiesel in terms of PM, NO x, CO and CO 2 emission reduction may represent an additional motivation for its wide use. However the poor low temperature operability is imperative. According to these observations a different behaviour of the after treatment system, especially as far as control issues of the Diesel Particulate Filter are concerned is also expected. The use of biodiesel as alternative to fossil fuel for light duty CI engines to reduce greenhouse gas emissions was widely investigated. However, poor stability of biodiesel - diesel mixture limits the use of biodiesel to low volume concentrations. This paper presents the results concerning the use of a novel fuel additive package containing, pour-point depressant with the aim to increase the quality and amount of biodiesel in the diesel-biodiesel blends.

  • New Oilseed Crops on the Horizon!
    New Oilseed Crops on the Horizon!: L. H. PRINCEN2 Fats and oils for food uses are now plentiful on a worldwide basis. Tallow, lard and fish oils, as well as vegetable oils, such as those derived from soybean, sun­ 1\ flower, palm, rapeseed, peanut and cottonseed, are often overproduced. Although many ofthese products are also used for industrial chemicals, they often are not [ ofthe most favorable composition for nonfood applications. A search for new oil­ 1\ seed crops with more advantageous oil composition has led to the development of l- excellent candidates that are now close to commercial acceptance. Among them are Crambe, Limnanthes, Vernonia, Sapium and Simmondsia. Other crops are at a much lower stage ofdevelopment but also have excellent potential. They include Cuphea, Foeniculum, Stokesia, Lesquerella and Lunaria. In this age ofsearching for renewable resources to replace petrochemicals and importedstrategic materials, c a well-organized research and development program on new oilseed crops could u soon result in American self-sufficiency for industrial oils andfatty acids. c Animal fats and vegetable oils make up an important part of the world's ag­ t ricultural production. Previous papers in this symposium have shown their eco­ a nomic impact from production through utilization. Although through the ages fats and oils have been produced mainly for food purposes, even centuries ago many also found use in such items as lubricants and greases, paints, soaps, lamp a oil and candles. Today, in the era ofpetrochemicals, fats and oils still playa major ( role in the production ofnonfood materials (Pryde, 1979). For example, in paints t and other coatings, where water-based latex systems have replaced much of the traditional vegetable oil-based paint market, approximately one-third ofthe bind­ ers used is still based on vegetable oils or their derivatives.

  • Value Addition Processing of Mfps
    Value Addition & Processing of Minor Forest Produce Value Chain for MFP – Stages The following commodity was studied extensively for the purpose of identifying the stages of value addition – Bael Pulp (dried) (Aegle marmelos) [ MSP – Rs. 27/kg ] Raw Material (Collection): The fruit should be picked individually, so that it does not fall on the ground to avoid cracking of the shell which may lead to spoilage during storage. Normally, the fruit should be harvested when yellowish-green and keep for 8 days while it loses its green tint. Then the stem readily separates from the fruit. A clear, gummy sap, resembling gum arabic, exudes from wounded branches and hangs down in long strands, becoming gradually solid. The fruits need to be harvested in January (2 to 3 months before full maturity) and ripened artificially in 18 to 24 days by treatment with 1,000 to 1,500 ppm ethrel (2-chloroethane phosphonic acid) and storage at 86º F (30º C). Care is needed in harvesting and handling to avoid causing cracks in the rind. Fruits need to be harvested by using long sticks attached with a hook and small bag around it. As a thumb rule, 1/3rd of the fruits should be left for consumption by birds and other animals for regeneration purpose. Cutting the branches or the whole tree for harvesting should be avoided. Ripen fruits can be harvested by shaking the branches. The hard shells of harvested fruits need to be breached by striking with a wooden or iron or stone hammer. The pulp should be removed by using a clean steel spoon or spatula and kept in clean clothes/ bamboo/ grass mats in the sun.
