Acrylamide can be generated from food components during tortilla chips frying. Thus, the aim of this research was to study different nixtamalization processes as traditional (TNP) with lime [Ca(OH)], ecological (ENP) with CaCO, classic nixtamalization (CNP) that uses wood ash and extrusion (EXT) with no Ca source on mitigating the acrylamide formation in deep-fat frying tortilla chips. Acrylamide quantification was done through HPLC-UV. Lower acrylamide content in tortilla chips was for CNP with 46.3 µg/kg, followed by TNP with 55.0 µg/kg, ENP with 694.6 µg/kg and EXP with 1443.4 µg/kg. Differences in acrylamide values among samples can be related to effect of cations (Ca, Mg, Fe, Zn, Na and K) present in wood ashes, lime and salts used as raw materials. Correlation of (r = 0.85; <0.0005) was observed in color of tortilla chips, moisture, texture, blisters, and oil with acrylamide. Nixtamalization process is an effective and inexpensive strategy for acrylamide mitigation.

A Randomized, Crossover Trial Assessing Appetite, Energy Metabolism, Blood Biomarkers, and Ad Libitum Food Intake Responses to a Mid-Morning Pecan Snack vs. an Equicaloric High-Carbohydrate Snack in Healthy Volunteers with Overweight/Obesity.

Background: The differential effects of pecans versus other popular snack foods on appetite and blood markers of metabolism and satiety have not been well studied. This study investigated the effects of a single mid-morning snack of pecans or tortilla chips on subjective appetite, food intake, blood measures of hormones and metabolites, and resting energy expenditure.
Methods: Twenty participants with overweight and obesity were enrolled in a within-participants, randomized crossover trial.
A Review of N-Heterocycles: Mousy Off-Flavor in Sour Beer.

Article Synopsis
- Beer contains over 600 flavor compounds, influencing the sensory experience that consumers enjoy, particularly in the rising popularity of sour beers, which have unique flavors compared to traditional styles like lager or ale.
- The unpleasant "mousy" off-flavor, reminiscent of mouse urine or stale cereal, is linked to specific compounds from the fermentation process and commonly appears in sour beers, wines, and other grain-based beverages.
- Research is ongoing to understand the formation of these unfavorable flavors and to improve the quality and safety of mixed-culture beers and non/low alcohol beverages, while addressing consumer preferences for balanced sourness.
Association between shift work in early pregnancy, snacking, and inappropriate weight gain during pregnancy: The Japan Environment and Children's Study.

Article Synopsis
- The study explored how working night shifts affects snacking habits during pregnancy, using data from a large Japanese maternal-infant study.
- Researchers analyzed eating behaviors, focusing on fast food and snacks, and calculated odds ratios for pregnant women on night shifts.
- Results indicated that while night shift workers didn't gain excessive weight, they did snack more frequently compared to those working during the day.
In search of better snacks: ohmic-heating nixtamalized flour and amaranth addition increase the nutraceutical and nutritional potential of vegetable-enriched tortilla chips.

Background: Nixtamalized flour snacks such as tortilla chips are widely consumed across the world, but they are nutritionally poor and contribute to obesity and other non-communicable diseases. The production of healthy versions of such snacks, by incorporating vegetables and improving the quality of the flours used in their formulation, could help address these nutritional challenges. This study compared the fortification of baked tortilla chips with vegetable leaf powders (kale and wild amaranth at 0%, 4%, 8%, and 16% w/w) and using two types of nixtamalized flour: traditional (TNF) and with ohmic heating (OHF).

Widely consumed thermally processed corn-based foods can have a great contribution to acrylamide dietary intake, thus bearing a high public health risk and requiring attention and application of strategies for its reduction. This paper reviews the literature on the acrylamide content of corn-based food products present in the market around the world. The potential of corn for acrylamide formation due to its content of free asparagine and reducing sugars is described.
