When prepared correctly, plants are a nutritional and low-cost source of protein for animal feed. The soybean is especially valuable as a food source because of its high protein content and favorable amino acid profile. However, soy also contains several enzymes that can negatively impact nutrition and potentially harm animals and humans. Cooking and drying…
Oil Oxidation: How To Measure It And Why It Matters
Oil oxidation, also known as rancidity, is a challenge that all processors in the edible oil industry must face. There is no avoiding oxidation – oil is always in a state of oxidation, and the process cannot be stopped completely. However, oxidation can be limited with certain steps. What is oil oxidation? Oxidation is an…
Boost Your Oil Yield: Why the Recycle Loop Matters
There are a few situations that can rapidly diminish profits at an expeller press processing plant. Along with the most common downfalls like unnecessary downtime and inadequate seed preparation, leaving oil in the meal has about the same result as, well, lighting your wallet on fire. To maximize profits, processors should aim to reduce the…
Soybean Meal: Protein Solubility vs. Protein Dispersibility Index
Preview in new tab Soybean is the most valuable oilseed meal on the animal feed market due to its protein content and favorable amino acid profile. Soybean also responds well to heat treatment used to destroy anti-nutritional factors (ANF) necessary for maintaining the health of monogastric animals. Although heat treatment is needed to destroy ANF,…
Maximize Your Expeller-Pressed Oil Process with Overflow
To be effective when processing with an expeller, operators must monitor and adjust several variables. A new batch of material or a different seed type will inevitably respond differently than the last. Everything from the storage of the raw seeds, upstream preparation, and wear on machine parts can impact the expeller-pressed oil process results and…
How High-Shear Dry Extrusion Advances Greener Oil Milling
Pursuing green initiatives in any industry can be difficult, but it can be particularly challenging for the oil milling industry. Regardless of whether oilseeds are processed for consumption, non-edible products like soap, fuel, or animal feed, the financial margin for error is slim. The decision to make changes to long-established practices or invest in new…
The Challenge of Small-Scale Oilseed Processing: Paying Off Your Investment
The “bigger is better” mantra has been touted for centuries, and the oilseed industry is no stranger to it. A few decades ago, processing 10-20 metric tons per day (MTPD) of oilseed was considered sizeable. Now, the average plant processes several hundred tons of oilseed per day. Enhanced machinery, the use of chemicals, and the…
7 Features of the Oil Expeller Press
The original oil expeller press was invented in the late 1800s by Anderson International’s founder, Valerius D. Anderson. This patented mechanical screw press design was a radical departure from hydraulic presses used at the time. The Anderson expeller’s primary advantage was that it allowed for continuous oil extraction and the processing of large quantities of…
Top 2021 Oilseed Trend: High Oleic Oil Demand Driven by Consumer Health Concerns
Rising health consciousness among consumers is driving demand for healthier product alternatives in restaurants, on grocery store shelves, and in the beauty aisle. Buzzwords like ‘clean,’ ‘natural,’ and ‘organic’ dominate product labels across these industries. The oil industry has not escaped this trend and has experienced a transformation over the past several years to meet…
