Stabilization of Rice Bran: A Review

Area of Science:

• Food Science
• Agricultural By-product Utilization
• Nutritional Science

Background:

• Global food security challenges are exacerbated by environmental limitations.
• Rice bran, a major milling by-product, is underutilized as a food source due to rapid deterioration.
• Hydrolytic rancidity, caused by enzyme activity, prevents direct use of rice bran in food products.

Purpose of the Study:

• To review methods for stabilizing rice bran and related by-products.
• To assess the efficiency of stabilization processes during storage.
• To discuss the impact of stabilization on rice bran's nutritional components.

Main Methods:

• Literature review of various rice bran stabilization techniques.
• Analysis of enzyme inactivation methods to prevent rancidity.
• Evaluation of storage stability and component integrity post-treatment.

Main Results:

• Enzyme inactivation (stabilization) is crucial for preventing rice bran deterioration.
• Various stabilization methods exist, each with varying efficiencies.
• The chosen method impacts the preservation of bioactive compounds in rice bran.

Conclusions:

• Stabilization is essential for transforming rice bran into a viable food ingredient.
• Effective stabilization strategies can mitigate food waste and enhance nutrient utilization.
• Further research into optimal stabilization techniques is warranted for maximizing rice bran's potential.
