This study investigated how the color and β-carotene content of crude palm oil (CPO) vary as it is processed into Red Palm Olein (RPOn). Significant changes in color and β-carotene content (measured by ΔE values) were observed at each refining stage, including water degumming (ΔE = 8.15), fractionation...

Tortilla chips, which are thin and crispy snacks, are generally made from corn flour using ultra-processing technology. This technology often has a negative effect on the nutritional content of a product. One way to increase the nutritional value of ultra-processed products is to add ingredients using...

The innovation of green-colored rice flour (GCRF) was achieved by adding suji and pandan leaves. However, the green color of flour tends to be unstable, as indicated by the rapidly decreasing chlorophyll levels during storage. Blanching of the leaves in an alkaline solution may be helpful. This study...

The palm oil industry plays a vital role in Indonesia’s economy. One of the key challenges in maintaining high crude palm oil (CPO) quality is accurately determining the ripeness level of oil palm fruits.
