Influence of acoustic cavitation and its combination with H2O2, acid, and alkali as a pre-treatment technique on lactic acid production from rice as a model food waste

Ultrasonics Sonochemistry
Acoustic cavitation was utilized as a pretreatment technique to modify a model food waste (rice) as the substrate of fermentation, enhancing the production of lactic acid. The comparison of a low-frequency (24 kHz) reactor with a high-frequency (120 kHz)

Development, Nutritional Evaluation, and Shelf‐Life Study of a Jackfruit‐Based Meat Analogue Enriched With Legumes and Spirulina

AgriFood: Journal of Agricultural Products for Food, EarlyView.
A jackfruit‐based meat analog enriched with legumes and spirulina was developed, optimized, and evaluated for sensory, nutritional, and shelf‐life qualities. The best formulation offered superior taste, texture, nutrient density, and maintained safety and quality for up to 60 days under frozen storage. ABSTRACT This study focuses on the development and
