The majority of the almond-related outbreaks have been associated with Salmonella. Therefore, it is necessary to find an effective method to inactivate these organisms on the raw almond before distribution in the market. This study was conducted to assess the effectiveness of superheated steam (SHS) treatments followed by catalytic infrared (IR) heat treatment to inactivate Salmonella populations on raw almond and to determine the effect of these treatments on the quality of raw almond. It has been found that SHS treatment for 70 seconds followed by catalytic IR heat treatment for 70 seconds was able to reduce 5.73 +/- 0.11 log CFU/g Salmonella population, and no survivors were found in the enrichment medium. The overall visual quality parameters of both treated and nontreated almonds were found within the acceptable limit. Therefore, SHS treatments for 70 seconds followed by catalytic IR heat treatment for 70 seconds could be an effective decontamination method for raw almonds.

Proteins and polyphenols exhibit distinct biological activities and functional properties. A comprehensive investigation into the formation mechanisms, structures, and functional properties of protein-polyphenol complexes will deepen our understanding of their interactions and establish a theoretical foundation and technical support for development of novel functional foods and pharmaceutical products. The almond protein-phloretin (AP-PHL) covalent complex was synthesized through the covalent binding of hydroxyl radicals to phloretin (PHL), utilizing almond protein (AP) as the raw material.

Analysing samples in their original form is increasingly crucial in analytical chemistry due to the need for efficient and sustainable practices. Analytical chemists face the dual challenge of achieving accuracy while detecting minute analyte quantities in complex matrices, often requiring sample pretreatment. This necessitates the use of advanced techniques with low detection limits, but the emphasis on sensitivity can conflict with efforts to simplify procedures and reduce solvent use.

The effect of partial replacement of cereals by increasing levels of almond hulls (AH) was tested in twenty-four lambs distributed into three dietary treatments: 1) diet without replacement of cereals with AH (0AH); 2) diet with replacement of cereals with 9% of AH (9AH); and 3) diet with replacement of cereals with 18% of AH (18AH). All diets included 40% dehydrated lucerne and 5% soybean oil. Dry matter intake, growth performance, feed costs, carcass traits, meat quality, and lipid oxidative stability of raw and cooked meat during refrigerated storage were evaluated.

Article Synopsis
- The study aimed to see if eating 2 oz of raw almonds daily could lower HbA1c levels in adults with high readings over a period of 16 weeks.
- Although participants consuming almonds gained slightly more daily calories, there was no significant difference in body weight or HbA1c levels between the almond group and the control group.
- However, the almond group showed improvements in diet quality and maintained their enjoyment of almonds over time, while showing changes in certain blood parameters, indicating they followed the dietary plan effectively.
