The Effect of Cooking Method and Cooked Color on Consumer Acceptability of Boneless Pork Chops

The objective was to determine the effects of sous-vide cooking and degree of doneness on consumer eating experience of pork chops when cooked color was expected to differ. The hypothesis was consumers would prefer a cooked brown color and would rate grilled chops more acceptable than sous-vide chops. Chops were cooked to 63 °C or 71 °C using either an open-hearth grill or a sous-vide device. Participants evaluated four samples for tenderness, juiciness, flavor, and overall acceptability. Participants rated a greater percentage of chops cooked sous-vide at 63 °C as tender (82.82%), juicy (55.83%) and acceptable (60.34%) compared with all other cooking method and degree of doneness combinations. Participants rated a greater percentage of sous-vide chops as tender and acceptable compared to grilled chops. Participants rated a greater percentage of chops cooked to 63 °Cas tender, juicy, flavorful, and acceptable when compared to 71 °C. Even when participants could visualize cooked color, they preferred chops cooked to 63 °C compared with chops cooked to 71 °C. Overall, participants preferred chops cooked to 63 °C compared to 71 °C regardless of the cooking method and preferred chops cooked to 63 °C using the sous-vide cooking method the most among all treatments.

Feasibility of Elder-Friendly Food Applications of Sacha Inchi According to Cooking Method: Focusing on Analysis of Antioxidative Activity and Brain Neuron Cell Viability

One of the objectives of this study was to determine the effect of the cooking method on the antioxidant activity of Sacha inchi (Plukenetia volubilis). This work was focused on the importance of performing proper cooking for studying Sacha inchi. The result of this study sheds light on preventing nutritional loss with appropriate cooking methods. Three types of cooking processes were selected: uncooked, roasted at 160 °C for 6 min, boiled at 100 °C for 13 min. The results of the present study indicated that roasted Sacha inchi is distinguishable for its high content of antioxidants (total polyphenol content 485.50 μM, total flavonoid content 0.02 μg/mL, DPPH free radical scavenging activity 33.05%, ferric reducing ability 0.19 μM). The results of the present study also indicated that Sacha inchi uniquely promotes HT22 cell viability. With roasted Sacha inchi treatment, HT22 hippocampal neuronal cell showed a significantly increased number of growth (p < 0.001). Results also suggest that the development of tenderized Sacha inchi could help the elderly consumers achieve their target antioxidant provision in smaller portion sizes, thus curtailing the peril of sarcopenia. The mousse type of elderly food may also change the taste of many other nut consumers as they may opt to start selling and consuming Sacha inchi. It could be in the Sacha inchi industry’s best interest to make certain all of the population’s textural favors are catered.

Effect of Cooking and Freezing on Levels of pesticides residues in Local Fresh Fish

Pesticides are an important part of pests controlling strategies. Misuse of such chemicals has been linked to pollution of various environments and toxicities that lead to various health conditions and diseases. Importance of healthy and non-contaminated fish for human diet is essentially required. Samples of 14 local fresh fish (tilapia, grey mullet, and cat fish) were analyzed for seven pesticides (endosulfan, heptachlor, malathion, chlorpyrifos, bifenthrin, deltamethrin, and fenoxycarb) using liquid chromatography with tandem mass spectrometry (LC-MS/MS). Heat processing applied for positive samples by two different cooking method (roasting at 79 °C for 10 min and frying at 210 °C for 40 min) have influenced the levels of studied pesticides and significantly reduced their levels by 53-95%. Freezing preservation of contaminated fish at -70 °C for one month only reduced the level of the pesticides by 6-30%, however, final reduced levels were not below recommended maximum residue limit values.

Speciation and Bioaccessibility of Arsenic in Rice and Its Implication in Risk Assessment

Numerous studies have studied the health risk assessment of human exposure to As or bioaccessible As via rice intake, however, the bioaccessibility of different As species in rice is seldom reported. In the present study, 31 rice samples were collected from markets or individual growers to investigate the speciation and bioaccessibility of As. Five different species (AsⅢ, AsV, DMA, MMA and AsB) were detected in rice samples from different regions, among which AsⅢ accounted for the largest proportion (62.95% in average), followed by DMA and AsV. In addition, the cooking method could facilitate the release of As from rice into gastric and intestinal juice, and subsequently increase the bioaccessibility of As. The bioaccessibility of inorganic As in cooked rice ranged from 71.83% to 100%, and that of organic As ranged from 31.69% to 61.04%. Non-carcinogenic and carcinogenic risk assessment of children and adults exposure to As via rice intake considering the bioaccessibility of cooked rice was carried out. The hazard quotient (HQ) of iAs and total As for children ranged from 0.21 to 1.61 and 0.48 to 2.26, respectively, while those for adults ranged from 0.12 to 0.88 and 0.26 to 1.23, respectively. Incremental lifetime cancer risk (ILCR) for children and adults ranged from 9.57 × 10-5 to 7.25 × 10-4 and 5.21 × 10-5 to 3.95 × 10-4, respectively. The results of risk assessment indicated that children would face a higher health risk than adults when they took the same type of rice as their staple food.

Effect of geographical location, insect type and cooking method on the nutritional composition of insects consumed in South Africa

Edible insects may be a sustainable source of protein and some other nutrients, especially for low economic status communities. The current study determined the influence of insect type, geographic location and cooking method on the nutritional composition of insects. The investigation would contribute to maximal derivation of the nutritional benefits of insects. Dried samples of four insect types, Gonimbrasia belina (mopani worm), Gynanisa caterpillar, termite soldiers/workers, and termite alates, were procured from different street vendors across Vhembe district in Limpopo Province, South Africa. G. belina samples were cooked by frying, boiling with and without salt addition. Generally, nutrient content varied significantly with insect type and geographic location (P<0.05). Protein content varied from 40 g/100 g in termite alates to 69.75 g/100 g in termite soldiers/workers. Termite soldiers/workers had the highest iron content (range: 545-629.5 mg/kg), whilst Gynanisa caterpillar had the highest zinc content (range: 122.14-150.33 mg/kg). Similarly, Gynanisa caterpillar had the highest levels of lysine (range: 0.80-4.53 g/100 g), threonine (range: 0.79-2.64 g/100 g) and isoleucine (range: 0.63-2.33). On the other hand termite soldiers/workers had the highest levels of valine (range: 2.20-3.47 g/100 g), leucine (range: 2.49-3.87 g/100 g) and phenylalanine (range: 1.38-3.55 g/100 g). Cooking method significantly affected nutrient retention. Boiling with salt added resulted in the highest retention of protein and total mineral content (ash), and, therefore, seems a suitable method for cooking insects. The findings indicate that, if optimally selected and cooked, edible insects can contribute significantly to the alleviation of protein, zinc, and iron deficiencies in target communities.

Effects of using chia (Salvia hispanica L.) mucilage and different cooking procedures on quality parameters of beef patties

This study was carried out to investigate the effects of chia (Salvia hispanica L.) mucilage (CM) as a fat replacer in grilled or pan-fried beef patties. For this purpose, beef fat was replaced by CM at levels of 0, 25, 50, and 75%. The use of CM and cooking method affected cooking-related parameters. Cooking yield was lower in pan-fried patties, while the addition CM increased the cooking yields. Moisture retention, shrinkage, changes in diameter, and thickness of grilled patties were improved compared to the pan-fried samples. The addition of CM increased moisture retention, while shrinkage values decreased. Results of our investigation revealed that CM retarded oxidative changes in pan-fried patties. Textural parameters and sensory properties of samples were not negatively affected by the addition of CM.

Effects of Sous-vide Cooking on the Initial Yield, Peak Force, and Elastic Modulus of Cooked Beef Semitendinosus

The objective of this study was to compare the traditional cooking method with sous-vide cooking at various cooking temperatures and times on the initial yield, peak force, and elastic modulus of semitendinosus (ST) beef. This study also examined the colour properties, cooking loss, and water retention of ST beef. Sous-vide samples were cooked inside vacuumized pouches at temperatures 60, 70, and 80 ℃ for 3 and 6 h. Meanwhile, the traditional cooking method was treated at 90℃ for 30 min. Reduced the initial yield, peak force, and elastic modulus of ST beef could be attained in 6 h at 60 ℃. Higher temperature and prolonged cooking time seem to cause meat to be tougher, likely due to the longitudinal myofibrils shrank. In terms of water retention and cooking loss, sous-vide cooked at 60 °C (regardless of cooking time) significantly exhibited better water retention and lower cook loss. This mild cooking temperature also best preserved the colour properties of lightness (L*) and redness (a*) than the other treatments.

Comparison of the single-step and double-step sous-vide treatment effect on the quality attributes of chicken breast •

Sous-vide treatment is a modern minimal processing cooking technique that uses a single-step temperature of 55–70 °C and longer time. The quality attributes of meat might be improved by including cooking steps at below 50 °C temperatures in the sous-vide treatment. The aim of this study was to investigate the effects of the double-step sous-vide treatments on the quality attributes of the chicken breast and comparing with the traditional single-step sous-vide treatments. The single-step sous-vide treatments were performed at 60 °C. In the double-step sous-vide treatments the first step temperature was 45 °C and the end temperature was 60 °C. Double-step sous-vide treated chicken breasts obtained higher tenderness, moisture content and lower weight loss compared to the single-step sous-vide treated chicken breasts. Double-step sous-vide treatment provided an attractive cooking method to produce high quality chicken breast, however, challenge tests for specific pathogens would be useful for the assessment of the microbiological quality for different treatment combinations.
