This application note summarizes a groundbreaking study in the world of food safety and conservation that delves into the aggregation-induced emission (AIE) phenomenon of nonconjugated rhodamine derivatives, sheds light on the underlying mechanism driving their luminescent properties and unlocks their potential in food spoilage detection.

Rice mainly consists of starch, but it also contains inorganic nutrients, and it has been reported that different inorganic elements have different distributions in a rice grain. We carried out elemental distribution imaging of inorganic nutrients with the HORIBA XGT-9500 X-ray analytical microscope. The result successfully visualized that P and K were accumulated in specific areas of a rice grain, while S and Zn were uniformly distributed within a rice grain.

In this application note, a method for accurately predicting the amounts of major constituents of kava root from spectroscopic absorbance and fluorescence measurements made with the HORIBA Aqualog® and the A-TEEM technique is presented.

Saffron is a target for adulteration due to its high price. Other compounds can be added, such as minerals, oils or synthetic colorants. The two in one Duetta spectrometer was used to rapidly acquire Excitation Emission spectra for different saffron samples from different suppliers.

A wide range of elements are present in plants. Some elements exist to play important roles as plant nutrients or enzymes, and some elements accumulate unexpectedly due to environmental pollution. While it is important to understand the bulk concentrations of individual elements from a nutritional and ecotoxicological perspective, the distribution of elements is also important for a better understanding of the mechanisms of metabolism and uptake in plants.

In this study, particle size of wheat flour is measured by laser diffraction technology that has emerged as the most important and effective technique in the world of particle size analysis. When compared with traditional sieve method, laser diffraction is fast, non-destructive, and provides automated measurement through a simple measurement workflow.

食用昆虫作为一种可能的解决方案已受到关注，作为一种补充来源，以减少粮食不安全，因为它们的营养价值，如蛋白质、脂肪和矿物质。Micro-XRF可以无损地了解昆虫体内的元素分布。本文利用HORIBA XGT-9500 x射线分析显微镜对食用蟋蟀进行了元素地图成像，发现其颌部富含锌。

Multilayer polymer films, composed of different materials, are used in a variety of industrial applications. The analysis of these multilayers is important to support, especially for safety and performances control. Here, we use Raman microscopy by cross-section analysis and confocal depth profiling to investigate the chemical composition of two multilayers films.

Aqualog A-TEEM光谱仪具有专门识别和量化蔓越莓中关键掺杂物的能力，这些掺杂物是最常见的蔓越莓膳食补充剂，包括松树皮，葡萄籽和花生皮提取物。

辣椒酱含有大量盐分，会增加患肾病和心脏病的几率。

面粉的粒径分布范围很广，其取决于所需的最终产品。

现如今有两种光学技术可用于表征乳液，即激光衍射法和动态光散射法。 这两种分析技术都具有快速可靠的优点。 然而，由于分析原理的差异，对于同一种样本进行分析会获得不同的结果。

豆酱是一种磨碎的豆制品，其中包含大部分种皮以及不同大小的肉质部分。这些组分的粒径对产品的口感、风味和稠度有直接影响。

乳液是将一种流体液滴悬浮在另一种流体中。乳液的稳定性取决于液滴的初始尺寸和表面活性剂的相关性质。在乳化过程中需要使用粒径分析来确保液滴的理想尺寸，并识别由于不稳定分散体引起的任何乳状液（液滴聚结）。

近年来，随着仪器成本的降低，时间分辨荧光技术的应用也越来越广泛。在食品工业中尤其如此，时间分辨荧光已被应用于食品的表征以及与食品安全和降解有关的方面。

本应用介绍了使用 XGT 9500 对食品进行异物分析。有以下三种分析：油性意大利腊肠上的异物、夹层火腿和香肠中的异物以及饮料产品中的苍蝇

随着人们健康饮食理念的不断加强，越来越多的人关注到食用油的作用和功效。因此寻找对于特级初榨橄榄油等产品的快速质量分析和评价方法已经越来越重要。

许多食品以颗粒形式存在，从粉末到乳液、悬浮液和颗粒。颗粒的尺寸分布会影响最终产品的味道、外观、稳定性、可加工性和功能性。 食品的正确颗粒表征需要一系列分析仪器。所有 HORIBA 颗粒技术均已成功应用于食品行业，包括激光衍射、动态光散射和图像分析。以下部分记录了粒度分析在食品工业中的具体应用。

我们喜爱的食物依靠调味剂（或香精）来增强它们的味道。调味剂可以是简单的盐或糖，也可以是水果提取物或是各种香料的混合物。调味剂可以降低食品加工成本，同时让饮食更健康。为了实现较高的效益，需要对粒度进行控制。厨师和食品科学家不仅关注各种调味剂，还考虑它在烹饪和制造过程中的表现。而这些在很大程度上取决于颗粒的大小。

质量控制是糖生产的重要组成部分。在这项研究中，LA-960V2能够快速分析颗粒分离和解聚状态下糖粉的粒径。

本研究侧重于对糖替代品颗粒的临界粒径进行表征，因为粒径对产品的流动性、溶解度以及粉末均匀性具有较大的影响。

本应用说明回顾了粒径分析在蛋黄酱和蛋黄酱产品形成中的重要作用，以及粒径变化如何影响这些替代品的口感和一致性。

巧克力中使用的可可粉的粒度会影响颜色和风味强度。该行业将“口感”称为可接受或不可接受的衡量标准。如果颗粒太大，它不会有一致的奶油味。可可颗粒的大小也会影响品尝时的苦味水平。
