“…A sample of accurately weighed 0.5 g crude oil was used to determine palmitic acid content (Pal), stearic acid content (Ste), oleic acid content (Ole), linoleic acid content (Lin), linolenic acid content (Linolenc), and other composition content of each oil by gas chromatography-mass spectrometry [ 78 ]. These contents were determined as follow: (a) saturated fatty acid content (Sat) % = Pal + Ste; (b) unsaturated fatty acid content (Unsat) % = Ole + Lin + Linolenc; (c) saturated/unsaturated ratio (Sat/Unsat) = saturated fatty acid content / unsaturated fatty acid content [ 79 ] .…”

Background Most of Camellia oleifera forests have low fruit yield and poor oil quality that are largely associated with soil fertility. Soil physical and chemical properties interact with each other affecting soil fertility and C. oleifera growing under different soil conditions produced different yield and oil composition. Three main soil types were studied, and redundancy, correlation, and double-screening stepwise regression analysis were used for exploring the relationships between C. oleifera nutrients uptake and soil physical and chemical properties, shedding light on the transport law of nutrient elements from root, leaves, and kernel, and affecting the regulation of fruit yield and oil composition. Results In the present study, available soil elements content of C. oleifera forest were mainly regulated by water content, pH value, and total N, P and Fe contents. Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining 74.0% the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel had synergistic and antagonistic effects. Increasing oil production and unsaturated fatty acid content can be accomplished in two ways: one through increasing N, P, Mg, and Zn contents of leaves by applying corresponding N, P, Mg, Zn foliar fertilizers, while the other through maintaining proper soil moisture content by applying Zn fertilizer in the surface layer and Mg and Ca fertilizer in deep gully. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting N, P, K, Cu and Mn contents in kernel, which determined the yield and oil composition of C. oleifera.

“…The minimum cooking time was defined through moving out a rice kernel at different time intervals during cooking process, placing it on a glass plate, and pressing it with a little long-handle spoon. The rice was cooked until no white core was visible in any kernels when pressing, following the method of Tao et al [23].…”

“…The fatty acid profile was determined as described by Tao et al [23]. For lipid extraction, rice flours (300 mg) were weighed into a 10 mL plastic centrifugal tube and mixed with 1 mL hexane and 0.25 mL of 2 mol/L KOH-methanol solution for 30 s. After being extracted for 40 min in the water bath at 30 • C using a 300 W ultrasonic probe, the sample was cooled to room temperature and mixed with 0.25 mL of 2 mol/L HCl solution for 1 min.…”

To establish the safe and reproducible effects of cold plasma (CP) technology on food products, this study evaluated the gelatinization parameters, fatty acid profile, and hygroscopic properties of rice grains repeatedly treated with low-pressure radiofrequency (RF) helium CP (13.56 MHz, 140 Pa, 120 W-20s, 0–4 times, and 300 g sample). Compared with the untreated (zero times) sample, with an increase in CP treatment times from one to four on rice, the water contact angle and cooking time decreased, while the water absorption rate and freshness index increased, and the pH value remained unchanged. CP repeating treatments essentially had no effect on the gelatinization enthalpy, but significantly increased the peak temperature of gelatinization. From the pasting profile of rice that has been repeatedly CP treated, the peak, breakdown, and setback viscosities in flour paste decreased. CP repeating treatments on rice did not change the short-range molecular order of starch. Compared with the untreated sample, the first helium CP treatment maintained the content of C18:1n9c, C18:2n6c, and C18:3n3, but the second to fourth CP treatment significantly decreased contents of these fatty acids (FAs) as the C18:0 content increased. The first three CP treatments can increase the water and sucrose solvent retention capacity in rice flours. CP repeatedly treated rice first exhibits the similar monolayer water content and solid surface area of water sorption. Principal component analysis shows that contact angle, pasting parameters, and fatty acid profile in milled rice are quite sensitive to CP treatment. Results support that the effect of low-pressure RF 120W helium CP treatment 20 s on rice grains is perdurable, and the improvement of CP intermittent treatments on rice cooking and pasting properties is an added benefit, and the hygroscopic properties of rice was kept.

Objective: Cold plasma (CP) treatment is used to remove contaminants like ergosterol (ERG) in cereal foods. Methods: The conversion of ERG into vitamin D (VD), gelatinization properties and fatty acid (FA) profiles were evaluated in wheat shorts treated with 120W low-pressure radiofrequency oxygen or helium CP for 90-120s. Results: Compared with the untreated samples, 46-64% of ERG was degraded and produced a maximum amount of vitamin D2 and Vitamin D3-like compounds in the 120W CP 90-120s treated samples. Oxygen CP had a higher capacity to degrade ERG than helium CP. The peak temperature of gelatinization was increased by both CP treatments, while the other gelatinization properties were not changed. The content of mono-unsaturated free fatty acids (FAs) in wheat shorts had no significant change, 88.3-95% of total FAs, 82.2-89.1% of unsaturated FAs and 80.4-87.2% of polyunsaturated FAs were maintained. Helium CP increased the contents of C18: 0, C18: 1n9c, C18: 1n9t, and C20: 3n6 and saturated FAs, and reduced the C20: 1 and mono-unsaturated FAs content. Oxygen CP did not change C18: 0, C18: 1n9c, C18: 1n9t, and C20: 1 contents, but reduced the C20: 3n6 content. The oxygen CP oxidized polyunsaturated FAs, leading to a decrease in the unsaturated FA content, while helium plasma caused the decomposition of monounsaturated and polyunsaturated FAs, and partially converted some unsaturated FAs into saturated FAs. Conclusion: CP treatment is useful to change ERG into VD in wheat shorts.
