Adulterated rice has been circulating widely among Indonesians lately. It’s not just a matter of fraud in trade; if consumed, adulterated rice can have consequences ranging from reduced nutritional value to health problems.

“In addition to the direct health risks from chemicals, consuming mixed and manipulated rice also has nutritional implications that need to be addressed,” said Faurina Risca Fauzia, a Nutrition Lecturer at ‘Aisyiyah University (Unisa) in Yogyakarta, on Monday (August 4, 2025).

Faurina stated that mixing premium rice with low-quality rice can significantly reduce the nutritional value of the rice consumed, such as decreasing the content of important vitamin B1. “Although these effects may not cause immediate fatal consequences, regular long-term consumption can lead to cumulative nutritional deficiencies that harm public health,” said Faurina.

Furthermore, consumption of low-quality or adulterated food products can increase the risk of chronic health problems. Studies show that food adulteration/mixing can contribute to increased blood sugar levels in consumers, which can potentially lead to diabetes, weight gain in the abdominal area, obesity, and increased blood lipid levels that can trigger high blood pressure. The practice of adulteration/mixing essentially alters the natural properties of food, thereby exacerbating the health risks that may already exist from consuming low-quality food or junk food.

Faurina said that various scientific studies confirm the understanding of the dangers of contamination in rice, whether intentional or natural. Prolonged exposure to harmful substances in adulterated rice can cause the accumulation of chemical compounds in the body. “This accumulation will burden the detoxification system of vital organs such as the liver and kidneys, which in turn can cause permanent damage to these organs,” she said.

Faurina explained that one of the most significant natural contaminants in rice is arsenic. Rice (Oryza sativa L.) has an extraordinary ability to accumulate arsenic, with concentrations that can be ten times higher than other cereals such as wheat. This is exacerbated by the way rice is grown, which is generally submerged in water, which supports the solubility of arsenic in the soil and its absorption into plants. Inorganic arsenic, the more toxic form, can enter rice through silicon transporters that accidentally carry arsenite. As a result, rice is a major source of dietary arsenic exposure, especially for populations that consume large amounts of rice.

“Arsenic exposure, even at low levels, can cause nausea, vomiting, diarrhea, irregular heartbeat, and blood vessel damage. At high levels and with long-term exposure, this substance can increase the risk of arsenic poisoning, type 2 diabetes, hypertension, skin disorders, nerve damage, heart disease, and various types of cancer such as skin, lung, and bladder cancer,” said Faurina.

How to recognize adulterated rice

Faurina said that people can detect whether rice is adulterated or not. First, consumers can start by understanding the visual signs, smell, texture, and taste. From its visual characteristics, it can be identified by its uneven or overly striking color.

“Adulterated rice often shows uneven color, where bright white grains are mixed with dull or yellowish ones. Some adulterated rice also looks too white and shiny, resembling plastic. Real rice generally has a natural white color and is not too shiny,” explained Faurina.

The second thing that can be seen visually is the varying size of the grains. Adulterated rice grains are often uneven, mixing long and short or large and small grains in one package. Genuine rice tends to be uniform in size and plump in shape with natural grooves on its surface. Fake or synthetic rice, on the other hand, appears slimmer, smooth without grooves, and clear.

“Then, the presence of foreign objects when washed. If plastic flakes, white powder, or other unusual particles appear when washing the rice, this should be suspected as an indication of adulterated or fake rice,” said Faurina.

In addition to visual signs, adulterated rice can also be recognized by its smell or aroma. The first thing to be suspicious of is a suspicious smell. “Adulterated rice may emit a musty smell, a chemical smell, a pungent smell like burnt plastic, or even no smell at all. Real rice generally has a neutral, slightly fragrant, or soft pandan aroma,” said Faurina.

Adulterated or genuine rice can also be identified by its texture when it is still raw. First, adulterated rice is often too smooth, slippery, and shiny like plastic when touched. Genuine rice has a surface that tends to be rough. Second, it is hard and not easily broken. If adulterated rice grains are pressed with a fingernail, they tend to feel hard and not easily broken. Good quality rice does not crumble easily when squeezed.

“Sticks to the hands. If the rice tends to stick to the palms when squeezed in a dry state, this could be an indication that the rice has been mixed with chemical lubricants,” said Faurina.

Real rice and blended rice can also be recognized after cooking. Rice made from blended rice can taste strange, be too soft, spoil quickly, or harden quickly and be difficult to digest after cooling (Unnatural Rice). Synthetic rice can also release water when cooked, rather than absorbing it like normal rice. Normal rice, made from genuine rice, will produce soft, fluffy, sweet, and easy-to-chew rice.

“To identify whether rice is adulterated or not, additional tests can also be performed. First, the water test: adulterated or fake rice tends to float when soaked in water, while real rice will sink because it has a higher specific gravity. The water used to soak real rice will turn cloudy and whitish, while the water used to soak fake rice will remain clear. Second, the burning test: fake rice made from plastic will melt or emit the smell of burning plastic when burned,” said Faurina.

Gerry Katon Mahendra, a lecturer in Public Administration at Universitas ‘Aisyiyah (Unisa) Yogyakarta, described the phenomenon of flying the One Piece flag as an expression of public protest against the government. The government should view this phenomenon as motivation; the public needs improvements to the current conditions.

“It is an interesting phenomenon (the flying of the One Piece flag). From a public administration perspective, this phenomenon is a form of public protest related to the state of governance, which is considered to be falling short of public expectations. For example, it relates to tax policies, employment, and the purchasing power of the people, which are considered to be falling short of expectations,” said Gerry on Saturday (9/8/2025).

Gerry said that the government should see this as motivation, that the public needs change or improvement from the current conditions. “This non-state flag can be interpreted as a symbol of criticism that should be responded to with better performance,” said Gerry.

He said that flying this flag is not a violation as long as it does not violate any laws, is not displayed alongside state symbols, and is not flown higher than or alongside the red and white flag. “I believe that this is part of the public’s expression of criticism and hope for better conditions,” said Gerry.

Gerry said that Law No. 24 of 2009 explains that the flying of non-state symbols such as organizational flags or cultural symbols must comply with regulations that prioritize the position of the Red and White Flag in the main position, allow foreign flags only in a diplomatic context, and prohibit separatist symbols that could disrupt the unity of the nation. It is clearly explained that the dignity of the National Flag must not be degraded, so the flying of symbolic flags, such as those that have gone viral recently, must refer back to the existing provisions.

“If they are flown alone in permitted spaces, it can certainly be interpreted as not violating the law,” said Gerry.

Gerry suggested that the government needs to apply a dialogical, persuasive, and participatory approach that provides space for the creative expression of the younger generation, while still instilling national values through education, cultural collaboration, and public role models. “If it is related to less than ideal conditions in the country, the government must not forget to remain open to criticism and to improve the quality of its performance,” said Gerry.

Gerry observed that to date, the central government and several local governments have not raised any issues, as long as the rules are not violated. However, at the technical level in the field, he saw several reports related to orders to remove certain images or symbols.

“The government should strive to be more consistent in its policies, not repressive, and prioritize an open and communicative approach towards the public. This effort is considered to be more effective in reducing polarization and increasing public awareness. Instead of prioritizing a harsh prohibition approach,” he said.

He also mentioned that young people today, who are part of Gen Z, are in a phase of growth where they are learning to understand various situations, including the current situation in the country. With Gen Z known for being creative, out of the box, and quick-thinking, it is very likely that the way they express their feelings will be different from previous generations, making cultural shifts inevitable.

“As long as it does not violate norms and rules, I believe it is acceptable. This is relevant to the saying that everyone has their time, and perhaps now is the time for Gen Z to express themselves in their own way. The task of the previous generation is to guide and direct them so that they do not go too far,” said Gerry.
