SPECIAL STORY 70 FEED & ADDITIVE MAGAZINE November 2022 PROCESSING OF DIFFERENT TYPES OF SOYBEAN MEAL (SBM) To obtain the SBM, it may be processed in a variety of different ways to increase the protein concentrations and to deactivate anti-nutritional factors. During different stages of processing, this feed ingredient is exposed to varying degrees of heating. Based on the processing, we can obtain different types of SBM such as full fat SBM (FFSBM), extruded expelled SBM, and solvent extracted SBM. Both full fat and extruded expelled SBM are obtained primarily from the dry extrusion process. The extruded expelled SBM undergoes an additional step of mechanical expelling of oil from the FFSBM obtained after extrusion. The solvent extracted SBM is obtained after the solvent extraction of the oil from the soybeans. This SBM is the most popular and is widely used across the feed industry. However, there is a need for the use of extruded FFSBM due to their extra benefits. In addition, there is a lack of clarity amongst many extruder operators on the optimum processing conditions for obtaining the best quality of this potential feed ingredient. BENEFITS OF FULL FAT SOYBEAN MEAL According to Ramos (2021), FFSBM is an excellent source of energy with high stability on fat. The nutritional quality and amino acid digestibility of full fat soybean meal can be better than the conventional solvent extracted SBM, if properly processed. IDEAL EXTRUDER TEMPERATURE TO PRODUCE BEST FULL FAT SOYBEAN MEAL Although there are different types of plant proteins used as low cost and sustainable protein sources, soybean meals are the most widely used source of high-quality plant protein for livestock, aquaculture, and especially for poultry feed. It is also considered as an effective feed ingredient that are less expensive and more sustainable that fish meal. Therefore, the understanding of its processing allows us to take advantages.
