Inhibition of L-Cysteine on the Browning of Fresh Wet Noodles

Abstract: This research explored the effect of L-cysteine on the browning of fresh wet noodles (FWN). With the increasing addition of L-cysteine (0.02–0.1%), the ΔL* decreased and Δa*, Δb* increased. The L-cysteine could reduce the pH value and polyphenol oxidase (PPO) activity and increase the retention rate of polyphenol of FWN. It suggested that L-cysteine could inhibit the browning of FWN by decreasing pH value, PPO activity, and the oxidation of polyphenols. In the in vitro PPO solution, the inhibitory effect of L-… Show more

“…The commercial value of fresh noodles is affected by their storage stability, appearance, mouthfeel, and cooking properties. However, a primary drawback of fresh noodles is their extreme vulnerability to deterioration, which was due to their high moisture content and rich nutritional substance that are favorable for microbial growth and physiological–biochemical reactions [ 4 ]. Freshly produced noodles will soon deteriorate regardless of being stored at room temperature or being refrigerated.…”

“…L -cysteine is an amino acid that is both safe and natural. It is commonly used in food processing as a food additive and acts as a reducing agent [ 63 ]. The wet milling fractionation of starch is mostly carried out at a temperature of 40 °C and an autoclaving time of 24–48 h. Different wet-milling procedures (e.g., acid solution, alkaline solution, alcohol) have been reported in several pieces of literature ( Table 1 ).…”

“…Recent studies have reported the use of silica and metal oxide aerogels. Silica is an exciting material for high-performance insulation applications due to its aesthetics, non-flammability, non-reactivity, and low thermal conductivity [ 63 ]. However, they have two fundamental flaws: weak mechanical properties, high susceptibility to cracks, and worries regarding long-term economic viability [ 186 ].…”

“…Basic proteins and peptides: protamine, lysozyme, polylysine, nisin, and diplococcin, have a role to prolong shel‐life (Li et al, 2014; Li, You, et al, 2021). Natural antioxidants, such as ascorbic acid, l ‐cysteine, and tea polyphenols, slow down the browning process, improve sensory shelf‐life, and discoloration ability (Wu et al, 2021). Emulsifying compounds (glycerin monostearate—monoglyceride, sodium stearoyl lactate, fatty acid sucrose ester, soy lecithin) promote or stabilize an emulsion, reduce the leaching of hydrated starch molecules from the starch granules, and suppress the recrystallization of amylose and amylopectin, thereby reducing the tendency of the starch to age (Li, You, et al, 2021).…”
