The contamination levels of beauvericin and four enniatins, A, A, B and B, in 207 samples of wheat flour and corn grits on the Japanese market were determined by an analytical method based on LC-MS/MS. The toxins were extracted from samples with acetonitrile-water (85:15, v/v) and then purified with C18 cartridges. The method was validated in a single laboratory using spiked samples at two levels; the recovery of the five toxins ranged from 91.1% to 113.8%. Enniatin B was frequently detected in imported wheat flour (81.8%) and domestic wheat flour (85.6%), and the highest concentration of enniatin B was present in a domestic wheat sample (633 μg kg). In corn grits, beauvericin was found in 34% of the samples, but enniatins were not detected at all. The maximum concentration of beauvericin in corn grits was 26.1 μg kg. Deoxynivalenol and nivalenol in the same samples were determined by a method using an immunoaffinity column. Co-contamination of deoxynivalenol and enniatins was observed in 61% of the imported wheat samples and in 58% of the domestic wheat samples. These results suggest the need for a risk assessment for cyclic depsipeptide mycotoxins in Japan and a study on the synergistic effect of deoxynivalenol and enniatins.

Cocoa is a high value product and therefore a potential target for economic adulteration with less expensive ingredients. Carob flour is less expensive than cocoa powder and is frequently cited as a potential cocoa substitute. While carob has legitimate uses as a cocoa replacement, these characteristics also make it a potential adulterant of cocoa powder.

Background: Canna edulis is a high-quality resistant starch raw material, especially for making flour products. This study aimed to investigate the effect of Canna edulis starch (CES) on the properties of flour, rheology of dough and quality of semi-dry noodles. The CES replaced part of the wheat flour in the semi-dry noodle formula.

This study was intended to provide a novel process that fills a knowledge gap in relation to the enhancement of pulses utilization. The primary goal was to develop an experimental framework for using a high-pressure supercritical fluid extruder (SCFX) as a continuous bioreactor to produce off-flavor reduced and functionally superior pulse flours and protein concentrates in a single step. The current study focused on using SCFX processing to remove off-flavor from pulse flour and protein concentrates, enhancing the quality, acceptability, and marketability of pulse-based products.

Over the last decades, eating habits have shifted towards convenient foods with shorter preparation times due to people's busy lifestyles and higher living standards. Rapid changes in dietary patterns and lifestyles with the industrialization and globalisation have led to the escalating incidence of chronic diseases, which has paved the way to greater interest in dietary changes regarding nutritional status and health benefits. Composite flour is a combination of wheat and non-wheat flours or exclusively non-wheat flour with improved nutritional value, therapeutic properties and functional characteristics.

Research Background: Porang ( Blume) contains a high amount of starch, glucomannan and Ca-oxalate. Soaking porang tuber in acid (citric acid) and salt (sodium chloride) solutions affects the Ca-oxalate content, functional, rheological and thermal properties of porang flour. The aim of this study is to thoroughly investigate the effect of soaking treatments in acid and salt solutions at different temperatures on the physicochemical, rheological and thermal properties, functional groups, molecular mass and morphology of porang flour.
