Most rice is consumed as cooked, milled rice, but a small portion is also ground into flour or separated into a starch fraction and used by the food industry as a gluten-free ingredient. This study aims to find out if different types of rice flour and starch, such as white and colored rice, could be used in industry. This study employs green modification techniques to slow down the digestion process by combining polyphenols with starch. Our initial study found that the raw colored rice has a lower glycemic index than other types of rice, such as brown or white rice. Another study that looked at how the quality of colored rice flour was changed by different methods also discovered that out of the six green methods (annealing, heat moisture treatment, ultrasound, pregelatinization, wet-microwave, and dry-microwave). It found that ultrasound improved the polyphenol bioaccessibility in the rice flour and reduced the digestion rate. The pregelatinization process led to the flour having high solubility and an estimated glycemic index. Different techniques affected the flour/starch quality in different ways. Therefore, for further industrial application, it could also be easier to select the method for food product based on their required techno-functional quality of flour/starch. In addition to the modification techniques, this study showed that the high bioaccessible polyphenol content and high polyphenol content in rice greatly slowed down the rate of digestion. This study also open for further exploring the possibility of using high polyphenol agricultural waste to modify starch and flour in a sustainable manner.
Rice (Oryza sativa L.) is a crucial staple crop that supplies nutritional sustenance for half of the global population (Shao et al., 2018). Moreover, rice constitutes a significant commercial crop in Thailand, with its grains serving as a staple food, and a diverse array of rice types is present throughout the nation (Suebpongsang et al., 2020). Multiple rice types have been developed in Thailand, including colored/pigmented rice and non-pigmented rice, commonly referred to as brown and white rice, which can be utilized in many industries (Yamuangmorn & Prom, 2021). Furthermore, rice is regarded as a naturally gluten-free ingredient. Rice flour or starch can be utilized to create a variety of products, including cookies, bread, noodles, and crackers. Due to the elevated carbohydrate content in rice, most rice products are regarded as having a high glycemic index (GI). The link between polyphenols and digestive behavior has become a topic of attention, particularly for rice and its products. Researchers predominantly conducted comparisons of the features of pigmented rice and non-pigmented rice (with/without eGI) across various areas or types (Tangsrianugul et al., 2019; Verma & Srivastav, 2020; Waewkum & Singthong, 2021). Nevertheless, there remains a deficiency in information regarding the association between endogenous antioxidant qualities and other starch characteristics, which might be further considered for predicting the nutritional value of rice and for enhancing the foundational knowledge necessary for the development of rice products. The versatility of rice flour in industrial applications is primarily influenced by its physicochemical properties and usefulness. Unprocessed rice has limited utility and applicability (Iqbal et al., 2023). Consequently, novel techniques are necessary to enhance the quality of rice flours for further processing. Therefore, this research may offer essential insights for further investigation into select rice varieties and modification techniques for specific industrial applications by utilizing the starch-polyphenols complex concept.

Plant-based refers to food or products that are primarily made from plants. It can be divided into two categories: one is food that comes entirely from plants and does not include any animal products, and the other is food that contains small amounts of animal products, such as products that contain milk and eggs in limited quantities, which may also be considered part of the definition of plant-based. Plant-based meat products that closely resemble real meat and attract consumers are considered a relatively new innovation. Although tofu, tempeh, and seitan have been around for a long time, recent discoveries have led to the production of plant-based meat products that provide a sensory experience, making it difficult for consumers to distinguish between real meat and plant-based meat. Furthermore, the development of plant-based food products must prioritize quality and safety to maximize consumer benefits. Textured Vegetable Protein (TVP) is a plant-based protein made from soybeans using an extruder. It is used as a primary ingredient in the production of plant-based food products due to several advantages. These include: • High Protein Content: TVP is made from soybeans with the fat extracted, resulting in a high protein content. • Texture: When rehydrated, TVP has a texture that closely resembles meat. • Versatility: TVP has a neutral flavor, allowing it to easily absorb the flavors of various seasonings and sauces. • Cost-Effectiveness: Compared to other protein sources, TVP is relatively inexpensive while providing desirable characteristics. These benefits make TVP an attractive option in the production of plant-based foods. This study focuses on developing TVP into a plant-based crab cake and investigating the shelf life of the product in a tightly sealed container under refrigeration. It also analyzes the hygiene and cleanliness of the production process and how these factors affect the presence or growth of microorganisms that may pose a risk to consumers, referencing the cold food safety standards of Thailand. Finally, recommendations for cleaning operational areas will be provided to establishments as a guideline for developing preliminary food safety procedures in laboratory settings.

Photocatalytic materials decorated with bi-metallic nanoparticles (Bi-Metallic NPs/ photocatalyst) was synthesized for the degradation of aflatoxin B1. Bi-metallic NPs/ photocatalyst were synthesized by ultrasonic irradiation. The as-synthesized was characterized the chemical characteristics by the transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction analysis (XRD), Fourier transform infrared spectrometer (FT-IR), zeta potential analyzer, and UV-visible spectrophotometer. Bi-metallic NPs/photocatalyst was used to evaluate the degradation efficiency of AFB1 in household wastewater under visible light. The degradation process was analyzed using high-performance liquid chromatography (HPLC) at a wavelength of 365 nm, revealing that AFB1 was completely degraded 100% within 2 minutes. This superior performance is attributed to its highly porous structure, increased specific surface area, and reduced electron-hole recombination rate, which demonstrate that the developed nanomaterial has successfully achieved AFB1 degradation.
