The consumer demand for meat analogs (MAs) is on the rise. Soy proteins are frequently used as the primary ingredient in MAs, but soybean may negatively impact human health and cognitive functions. The aim of this research was to develop alternative chicken nuggets using mushroom and chickpea flour. Effect of different sources of mushroom and starch in the textural and sensory quality of nuggets were determined. Phoenix mushroom was chosen based on nuggets' textural and sensory qualities. Different ratios of mushroom and chickpea flour (0:70, 15:55, 55:15, and 70:0, w/w) were tested to prepare the nuggets. Based on protein, textural and sensory qualities compared to chicken and commercial plant-based nuggets, the mushroom to flour ratio of 55:15 was chosen. The results showed that tapioca starch-containing nuggets had a better texture and were more palatable to consumers. The processed nuggets demonstrated lower protein (6.88 vs 11.72%, dry wt. basis) but better cooking yield (87.65 vs 85.29%), moisture retention (77.86 vs 75.16%), fat retention (90.55 vs 88.39%) and higher consumer acceptability than commercially available soy-based nuggets. The results of the study suggest that mushroom and chickpea flour may replace soy protein in meat analogs.

Peanut protein hydrolysates with varying degrees of hydrolysis (DH) were prepared by using Alcalase and Flavourzyme. The enzymatic hydrolysis highly influenced a transformation of protein secondary structures, particularly from β-sheet to β-turn structures (11–21 %). The DH impacted functional properties and anti-free radicals' activity of peanut protein hydrolysates. Flavourzyme-derived protein hydrolysate (FPH) with DH5% had the maximum potential as an emulsifier (54.50 ± 0.71 %, p < 0.05). The effectiveness of protein hydrolysates in preventing the oil separation and enhancing the oxidative stability of peanut butter was dependent on the type of enzyme and DH. The inclusion of partial hydrolyzed protein (DH5%) produced by the Alcalase (APH) substantially decreased the occurrence of oil separation; whereas FPH with DH5% significantly retarded increment of PV, TBARs, CD in peanut butter during the storage period (p < 0.05). This study indicated the possible use of partial hydrolyzed proteins as a stabilizer in peanut butter by slowing lipid oxidation and increasing oil entrapment.

Pulsed electric field (PEF) is one of the emerging technologies that has been applied in many aspects of the food industry. This study examined the impacts of a PEF on the cooking quality, physicochemical properties, nutritional factors, and in vitro protein and starch digestion of two varieties of rice, including Jasmine 105 (white non-glutinous rice) and San Pa Tong 1 (white glutinous rice). Response surface methodology (RSM) and a three-level, three-factor Box–Behnken design were employed to assess the effects of the pulse number, electric field strength, and frequency on cooking time. The findings demonstrated that the number of pulses was a crucial factor influencing cooking time. Under optimal conditions (3347–4345 pulses, electric field strengths of 6–8 kV/cm, and frequencies ranging from 6 to 15 Hz), the rice cooking time was significantly reduced by 40–50% (p < 0.05) when compared to a conventional method. Moreover, PEF-treated rice showed a significant enhancement in in vitro protein and starch digestibility (p < 0.05), as well as retained a higher content of rapidly digestible starch. These results suggested that PEF treatment is a promising green technology for producing a novel quick-cooking rice with an improved eating quality.
