Peanut proteins: Extraction, modifications, and applications

Abstract. As naturally sourced proteins, peanut proteins have garnered significant attention from the food industry, owing to their numerous advantages, such as easy extraction, non-pungency, and high bioavailability. Furthermore, peanut proteins are highly digestible in the gastrointestinal tract and boast a high net protein utilization rate

Peanut seeds are rich in oil, which exists as oil bodies (OBs). By extraction, peanut crude OBs are obtained and can be used as a food ingredient. In a previous study, it was found that the crude

Aqueous enzymatic extraction of peanut oil body and protein

Aqueous enzymatic extraction (AEE) is a new technology for extracting vegetable oil body which has the advantages of low energy consumption, product safety, mild reaction conditions, and simultaneous separation of oil and protein. Among the enzymes tested in the present work, Viscozyme L (compound plant hydrolase) exhibited the highest extraction activity during peanut oil extraction

In aqueous enzymatic extraction, enzyme preparations are applied to mechanically crushed peanuts to increase the degree of damage to the cell wall. Although the reaction time required for aqueous enzymatic extrac- tion is increased compared to aqueous extraction, the peanut OB extraction efficiency is higher6）.

Composition and structural characterization of peanut crude

The composition and structure of peanut crude OBs were analyzed in this study, which might give some hints for improving aqueous enzymatic extraction processing of peanut free oil. CRediT authorship contribution statement. Chen Liu: Conceptualization, Methodology, Investigation, Data curation, Writing - original draft.

The oil extraction using cold-pressing method is performed at temperatures below 60 °C while in a hot-pressing condition, high temperatures are applied (Tan et al., 2020). Although peanut oil produced by hot-press is more popular due to its better aroma and flavor, it may lose its micronutrient due to proton denaturation at high temperatures.

The Mechanism of Extraction of Peanut Protein and Oil Bodies

2.2 Extraction of proteins and oil bodies Peanut protein and oil bodies were extracted using the graded extraction method20）and aqueous enzymatic extrac-tion of maize germ21）, respectively, with some modifica-tions. The skinless peanut seeds were ground in a high-speed universal grinder（FW-100; Beijing Ever Bright

In this study, the relationship between the composition and rheological properties of peanut oil bodies from aqueous enzymatic extraction was evaluated. Aqueous enzymatic extraction using a combination of cellulase and pectinase at a 1:1 ratio effectively destroyed the structure of the cell wall and resulted in the maximum oil body yield of 90.7%.

How is peanut oil extracted?
Peanut oil is typically isolated from peanuts using conventional extraction methods, such as mechanical pressing and solvent ( n -hexane) extraction [ 29 ]. However, many of the peanut proteins are denatured as a result of high temperatures during pressing or due to exposure to the organic solvent.
Which method is used to extract peanut protein?
2. Extraction method The extraction method used significantly affects the structural, functional, and physicochemical properties of peanut protein ingredients. The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [ 27 ].
How can aqueous enzymatic extraction improve the function of Peanut proteins?
Discuss extraction methods, modifications and applications of peanut proteins. Aqueous enzymatic extraction can efficiently separate oils and peanut proteins. The functionality of peanut proteins was significantly improved after modification. Native and modified peanut proteins can be used for a variety of purposes in foods.
Why is US pretreatment used in the extraction of peanut oil & proteins?
US pretreatment technique can be applied for the extraction of peanut oil and proteins to improve their heat-induced gelation properties by modifying their molecular structure to the denser and more homogeneous network (more stable) which is less sensitive to enzyme hydrolysis ( Fig. 13 ).
